Everything You Need To Know About Reverse Cycle Air Conditioning

By | Air Conditioning

Here in Sydney, we experience a wide-ranging climate. Although not as extreme as other parts of the world, we still endure sweltering summers and chilly winters. On top of this, many houses here (particularly older ones) are poorly insulated, making air conditioning a staple.

Because of this, you will likely need an air conditioner that both heats and cools to stay comfortable all year round. The solution? Reverse cycle air conditioning.
Air Conditioning

Reverse cycle air conditioning is ideal because of its heating and cooling capabilities, making it the most energy-efficient option.

A reverse cycle air conditioner is a unit that has both heating and cooling capabilities. This is the most energy-efficient way to control your home’s climate in both winter and summer, as you will only need to install a single system rather than separate ones for different seasons.

How Do They Work?

The way that reverse cycle air conditioners (also known as heat pumps) work is quite simple. They function in a similar way to a refrigerator in that they have an internal coil and external coil, which are connected by piping that is filled with refrigerant. When the unit is being used to warm a room, the refrigerant is pumped from the compressor to the internal coil at high pressure. The refrigerant is then passed through the external coil, expelling any cold air picked up at the internal coil. When the unit is in cooling mode, the two coils’ role is reversed by reversing the refrigerant’s flow.

What Are The Benefits of Using Reverse Cycle Air Conditioning?

There are several benefits of using a reverse cycle air conditioner:

• They are one of the most energy-efficient ways to control the climate in your home

• They provide both heating and cooling, so you only have to buy a single system

• They remain cool to touch at all times because they have no exposed elements or flames

• They also filter and dehumidify the air

• They are flexible, with a range of configurations and features to suit the needs of any home

• They run very quietly

• They are better for the environment

• They are extremely sturdy and will last for many years

What Kinds of Reverse Cycle Air Conditioning is there?

They are different types of reverse cycle air conditioners to choose from, and deciding which is best for your home will depend on a few things, like how big your home is and how many rooms you wish to heat/cool.

Split Systems

This is the kind of system where the condenser is fixed externally outside the home, and the head unit is fixed inside the home. These are connected by piping, which carries the refrigerant. The indoor unit is usually fitted to a wall. Split systems are area-specific, meaning they are limited to cooling/heating a single room, so they are best suited to small properties or apartments. If the ability to heat or cool multiple rooms is needed, a multi-split system may be the better option for you.

Multi-Split Systems

Multi-split systems are systems with more than one indoor unit connected to a single outdoor unit. These systems can have up to seven internal units, and each one can be controlled independently. This means that specific rooms can be set at different temperatures, all from a remote. They are great for larger homes or homes that wish to control the temperature in several rooms.

Ducted Systems

Ducted systems consist of a heat pump located outside or in a roof space, ducting that distributes the warm or cool air throughout a house, and vents that blow the conditioned air into a room. This type of air conditioning will require a certain amount of cavity space for installation, so it may not be suited to every home. They are best suited to larger homes or commercial spaces looking to control the entire building’s temperature. Some ducted air conditioning systems even allow for separate zones, meaning you have temperature control of individual rooms.

The Best Type of Air Conditioner for Apartments, Single Story or Multi-Story

By | Air Conditioning

Choosing an air conditioner can be a confusing affair. There are several different brands, models and configurations to choose from, and figuring out which of these is best suited to your house will require you to think about many things: how big is your home? How many floors do you have? How many rooms do you want your air conditioner to heat or cool?

Every air conditioner serves different needs, so let’s work out what type is best for you.

Best type of air conditionerThe best type of air conditioner depends on your living circumstances; whether that be an apartment, single-story, or multi-story house.

To help you make the right choice, let’s look at the best type of air conditioner for each type of house.

Apartments

If you want to get an air conditioner for your apartment, there are a few things you’ll want to consider that will affect what kind of system you get. First of all, whether you rent or own your apartment will greatly impact the choice you make. If you rent, you may be limited to what kind of system you can have, and in this case, a window, wall or portable unit might be the most suitable. These are self-contained, meaning they contain the compressor and the evaporator in a single unit.

If you do own your apartment, you will have more freedom when choosing what kind of system you go for. However, you will still have to consider the regulations set by your apartment’s body corporate committee before you jump in and buy one. Otherwise, a low-profile wall mounted or floor standing split system is probably the most appropriate option, seeing as apartments tend to be smaller and more open-plan than houses. If you want to control the temperature in multiple rooms, a multi-split system would be suitable.

Single Story Houses

When it comes to houses, let’s assume you own yours. If you do not, then again you will have to discuss with your landlord what’s possible. In some circumstances, your landlord will be fine with installing an AC unit in your home, as this will increase the value of the house. They may even consider paying for some of the installation themselves. If you own your home, then it’s entirely up to you what kind of system you choose. What kind of house it is will have the most significant impact on what kind of unit you choose.

For single-story homes, single split systems are an excellent choice. These are area-specific, meaning they are limited to cooling/heating a single room (depending on the layout of your home this may not be an issue for you, for example, if you have an open plan home and the unit is in a central area). They are a very cost-effective way to control the temperature in a home.

If you have a larger home or want to control the climate in multiple rooms, but do not have space for multiple outdoor units, a multi-split system is a great choice. These systems air configured so that several indoor units (which can differ in size, capacity and type) are connected to just one outdoor unit.

Multi-Story Houses

Standard multi-split systems can provide heating and cooling for up to 5 rooms and allow you to control room temperatures individually, making them ideal for multi-story homes. They are also quite efficient, making them the most economical option for larger places. There are deluxe multi-split systems for larger luxury homes that can heat/cool up to 15 rooms. Despite their powerful output, the outdoor units are compact, making it a great solution for modern homes with limited space.

For larger multi-story homes, ducted systems are another great option. These are the top-of-the-line air conditioners and, like multi-split systems, they also heat/cool multiple rooms. But rather than being specific to particular spaces, they treat the air in the whole house. You might have heard these being called central heating or central cooling.

This type of system is concealed and less obtrusive than the other systems we’ve mentioned. Generally, they are more expensive to run but with the main advantage of cooling a larger area.

Some ducted air conditioning systems allow for separate zones, meaning you have temperature control of individual rooms. However, it is important to note this feature will incur more costs. All in all, ducted AC units are a quiet and effective way to ensure climate control in a large multi-story home.

From AC installations to repairs and maintenance, we always make sure you receive the best possible service.

Improve The Air Quality In Your Home With These 6 Easy Steps

By | Air Conditioning

Indoor air quality can have a huge impact on health and wellbeing. Exposure to contaminants and allergens such as dust, mould and pollution may not seem like a big deal – these surround us outside every day. However, over time, these can pose a threat to you and your family.

In the interest of keeping your home clean and safe, we’ve located some of the best tricks to keep your air quality in check.

Air QualityThe air quality in your immediate environment can have a huge impact on your health. Here are 6 ways to improve the air quality in your home.

Symptoms of health problems caused by poor indoor air quality are often subtle, ranging from the sniffles and itchy eyes to a cough you cannot shake or irritated skin. Some people are more sensitive than others, but everybody should be concerned about their home’s air quality. Here are easy 6 ways you can make some improvements.

1. Keep Your Air Conditioner Clean

If you have an air conditioner, it is important to keep it spotless to ensure you’re not circulating contaminants throughout your home. The easiest (and most efficient) way to this is to clean your air filters every other month. Their purpose is to filter the air that passes in and out of your HVAC system, and they collect small particles of contaminants that may affect the health and wellbeing of you, your family or your employees, including dust, dirt, pollen, mould, lint and other fibres, bacteria, hair or animal fur, and particles of wood, metal or plastics. Simply remove the filter and vacuum or brush it thoroughly (outside). Keep an eye out for any holes, wrinkles or tears – these mean that your filter needs replacing. Check out our guide to cleaning and replacing AC filters here.

2. Consider Buying Some Indoor Plants

Indoor plants don’t merely give off the presence of a healthy home, they actually assist in creating one. Some indoor plant varieties can help improve air quality by absorbing harmful toxins from the air. In fact, NASA recommends two or three plants in 8 to 10-inch pots for every 100 square feet. Different plants are suitable for different environments. So do some research into what the right kind is for you. Some plants you may want to look in to include:

• Spider plants

• Dracaenas

• Golden pothos

• Bamboo palms

• Rubber plants

• Peace lilies

• Boston ferns

• Aloe vera

3. Clean Your Home Regularly To Remove Dust Mites

Dust mites are one of the most common contributors to poor indoor air quality. These are microscopic creatures that are particularly common in humid and coastal parts of Australia. They often live in bedding, carpets, upholstered furniture, and clothing and are among the most common allergen triggers for asthma. Be sure to clean these items regularly to help remove dust mites from your home. A few tips:

• Open your curtains and windows and air out your home regularly

• Wash sheets and pillowcases with low allergenic washing soap in a hot wash (above 55 degrees)

• Vacuum carpets and soft furniture weekly

• Dust regularly using a damp or electrostatic cloth

4. Consider an Air Purifier

If you live in a particularly polluted area or your family is sensitive to poor air quality, you may want to consider investing in an electric air purifier. These devices remove contaminants from the air in a room such as dust, pollen, pet hair, mould spores, dust mite feces, smoke particles and volatile organic compounds (VOCs).

5. Ditch The Aerosols

Cleaning and personal products that come in an aerosol can contain VOCs like butane and propane, which are bad for air quality. Try ditching these for non-aerosol alternatives like roll-on deodorant and spray bottle cleaning products.

6. Watch The Level of Humidity In Your Home

Dust mites and mould love humid environments. Keeping humidity around 30%-50% is ideal so consider purchasing a dehumidifier or an air conditioner during summer months to help control these levels. Other ways to reduce your home’s humidity include airing out areas that are particularly moist like bathrooms, laundry and kitchen, using exhaust fans where possible, fixing any leaky plumbing, and avoiding overwatering houseplants.

14 Tips That Will Make Your Home Energy Efficient And Cut Costs

5 Telltale Signs That Your Air Conditioner Needs Replacing

Air Conditioning Installation: A guide from start to finish

Buying an air conditioner

The 5 Step Checklist Before Buying an Air Conditioner

By | Air Conditioning

Buying an air conditioner is exciting. Australia’s climate can be harsh – summers are swelteringly hot, and winters can get quite chilly. An AC is an ideal utility to solve both those problems.

It’s no surprise then that roughly 2 in 3 Australians have an AC unit in their home. If you’ve been thinking about getting one for some time and are ready to take the plunge, that’s great! Now you’re faced with the task of deciding what kind of system to get. There’s a multitude of choice out there, so we hope this 5 step checklist assists in buying an air conditioner that’s right for your needs.

Buying an air conditionerFrom budget to energy efficiency, we’ve created a checklist of five key things to consider before buying an air conditioner.

1. What Kind of System Is More Suitable For Your Home?

There are three main types of AC systems to consider: split systems, multi-split system, and ducted systems.

Split systems are a great choice for homeowners looking to heat a single room or large area. This system has a condenser that is fixed externally outside the home and a head unit inside. Bear in mind that if there are several walls in an interior zone, a split system may be limited in its capacity to control the temperature beyond the zone. If the ability to heat or cool multiple rooms is needed, a multi-split system may be the better option for you.

Multi-split systems comprise of one outdoor unit that is connected to multiple indoor units.
There are numerous benefits to a multi-split air conditioning unit. They are extremely efficient and capable of powering up to six interior rooms at once. With this system, each indoor unit can be controlled individually. This means that specific rooms can be set at different temperatures, all from a single remote.

Ducted air conditioning systems feature some key differences to split and multi-split systems. A ducted air conditioner is installed internally, often within the roof. From the central unit, a series of ducts cools or heats individual rooms. This type of air conditioning will require a certain amount of cavity space for installation, so may not be suited to every home.

2. So, What Is Your Home Like?

So then – what kind of house do you have? Consider these features before buying an air conditioner, as they may affect what kind of system is best suited.

• Is it insulated?

• How big are the rooms that you want to cool/heat?

• How many rooms do you wish to cool/heat?

• What’s the layout of these rooms?

• Does your home get lots of natural sunlight?

• Does your home have many windows?

• Where do you live? Is it cold, hot, humid?

3. How Energy Efficient Is The System?

All new AC units will have an energy efficiency rating. They usually have two stickers – one for heating and one for cooling (if the unit is a cooling-only device, and then it will only have a blue sticker, if it a heating-only device, it will only have a red sticker). This will influence the choice you make.

As you may have guessed, the more stars, the more energy-efficient the unit is. The maximum possible rating for each side is 10 stars. If the product is rated above 6 stars for heating or cooling, it will show a ‘super efficiency rating’, which goes up to 4 stars (6 + 4 = 10). They also have capacity output and power input readings – basically how much heating and cooling the unit can produce and how much power it needs to run respectively. When comparing the star rating, you’ll want to compare systems with similar capacity output and power input readings.

It’s important to remember that units with lower ratings aren’t poor quality units. For a product to be rated at all, it needs to pass rigorous efficiency tests, so the base rating of 1 star is actually quite efficient. It only gets better from there, and the choice you make will depend on your budget.

4. What’s Your Budget Like?

Obviously, one of the biggest factors that will influence buying an air conditioner is how much money you have to spend. Air conditioning is an investment. It may require a substantial initial outlay, but you will save money in the long run.

Air conditioners range from anywhere between $500 and $5000+, so how much you can afford will affect what kind of system you get (for example, multi-split systems are more expensive than split systems), what features it has, and how energy efficient it is.

5. What Features and Functions Do You Need?

Different air conditioners have different features and functions, and this affects how expensive they are. Some might be extremely important to you and your lifestyle. Some not so much. Here are a few features you may want to consider:

• Fan speed

• Human presence sensor

• Sleep mode

• Wi-fi connectivity

• Remote control type

• Noise reduction

• Adjustable or oscillating louvres

• Restart delay

• Operation options (cooling, heating, fan, auto modes, dry air, economy modes)

Air Conditioning Glossary: Key Terminology Explained

By | Air Conditioning

All trades have their own set of terms and jargon that may sound like gibberish to the average consumer. The world of air conditioning is sadly, no different. When it comes to buying, installing and repairing an air conditioner, there is some terminology that you may hear cropping up again and again. Instead of having to nod your head confused, as a repairman unloads these new terms, we thought we’d cover some of the basics for you in our air conditioning glossary. This way,  you should be able to make more informed decisions regarding your AC needs.

air conditioning glossaryFrom ARC to zoning, this air conditioning glossary will cover some of the key terminologies you might encounter in the world of AC.

Here’s our air conditioning glossary of trade-specific terms you should know:

AIRCON FILTER: Filters are an important component of your AC system. They are usually made of a fine material like pleated paper or cloth stretched across a sturdy frame. Their function is to filter the air that passes in and out of your HVAC system. They collect small particles of contaminants that may affect the health and wellbeing of you, your family or your employees, including dust, dirt, pollen, mould, lint and other fibres, bacteria, hair or animal fur, and particles of wood, metal or plastics.

ARC: This is the Australian Refrigeration Council, the ‘peak industry body’ for refrigeration and air conditioning. They provide leadership and knowledge to the climate control industry through licensing and regulatory assistance, technical advice, promoting training quality, connecting customers to ARC-licensed businesses and providing free promotional materials for ARC-licensed businesses.

ARCTICK: The ARCTICK license must be held by any person who carries out work with refrigeration and air conditioning (RAC) equipment. Handling fluorocarbon refrigerant without a Refrigerant Handling Licence is an offence. You should only hire an AC specialist with an ARCTICK license.

COMMISSIONING: Air conditioning commissioning is the process of inspecting a new unit after installation, making sure it is running perfectly.

DUCT: Ducts are the passages used in heating, ventilation, and air conditioning that deliver and remove air. They are used in ducted systems.

DUCTED SYSTEM: Ducted air conditioners are installed internally, often within the roof. From a central unit, a series of ducts will cool or heat individual rooms. This type of air conditioner will require a certain amount of cavity space for installation, so may not be suited to every home. They are more suitable for commercial or industrial facilities.

INDOOR UNIT: The indoor unit is located inside. It is the part that blows hot or cold air into a room. It contains the heat exchange coil, filters, remote receiver and fan.

HEATING OR COOLING CAPACITY: This is the amount of heating/cooling the unit can produce.

HVAC: This stands for heating, ventilating, and air conditioning – a trio of functions that, as a whole, control thermal comfort and air quality in a building. It is basically a blanket term encapsulating everything from a split AC unit for a house, to a large ducted air conditioning and ventilation system for an industrial complex or skyscraper.

MULTI-SPLIT SYSTEM: This system comprises of one outdoor unit which is connected to multiple indoor units. There are numerous benefits to a multi-split air conditioning unit. They are extremely efficient and capable of powering up to six interior rooms at once. With this system, each indoor unit can be controlled individually. This means that specific rooms can be set at different temperatures, all from a remote.

OUTDOOR UNIT: The outdoor unit is the external part of the AC system, which contains the compressor, fan, and heat exchange coil, and pumps refrigerant to and from the indoor unit where it is heated and cooled.

REFRIGERANT: Refrigerant is the substance that ‘conditions’ the air it blows. Without refrigerant, air conditioners, fridges or freezers wouldn’t exist. It is a compound, either fluid or gas, that creates hot and cold air when combined with components like compressors and evaporators.

Some kinds of refrigerants are outdated, such as R12 or R22. These substances are older and are known to contribute to the greenhouse gas effect. The R22 started being phased out in 2010 and R12 was phased out in the 1990s. Hydrofluorocarbons (HFCs) like R410A and R134 is the standard today.

REGASSING: Although relatively uncommon, regassing is one of the key processes involved with air conditioning maintenance and repairs. If installed correctly, an air-con unit should not usually have to be regassed. However, older units, or those that weren’t installed by a professional installer, may need to be assessed and serviced. This involves checking for refrigerant leaks, fixing a leak if present, and replacing refrigerant if required.

SPLIT SYSTEM: Split systems are prevalent in homes all sizes. This type of air con refers to a system where the condenser is fixed externally outside the home, and the head unit is fixed inside the home.

THERMOSTAT: The device that controls the climate of a room by relaying information to the AC unit.

ZONING: The process of controlling the climate of separate rooms in a building. Older air conditioners could only be set to a single temperature. However, modern technology allows us to now control the temperature in separate rooms with a single unit.

14 Tips That Will Make Your Home Energy Efficient and Cut Costs

By | Air Conditioning, Electrical

The weather in Sydney is harsh. Summers are sweltering, and winters can get quite cold – not to mention that many older homes aren’t built for the cold weather. Air conditioning is prevalent in Sydney; roughly 2 in 3 homes in Sydney have air-con installed. However, this means that many residents have to face an ongoing battle with energy bills – ensuring their homes are as energy-efficient as possible. Are you fretting that your bills are higher than they should be? We’re here to help.
energy efficient

Energy bills are a concern for every Australian. Here 14 tips for making your home more energy-efficient.

There are several things you can do to make your house more energy-efficient. Some are cheap; some more expensive, some are suitable if you’re renting, some are only possible if you own your home. Let’s take a look!

Use Light Coloured Paint Inside – Paint your walls with light coloured paint (such as white or cream). This will help reflect sunlight inside, making rooms feel well-lit and reducing the need to use lights.

Insulate Flooring – There are many options for flooring insulation. What you choose will depend on what kind of home you have and how much you want to spend. If you can access underneath your floors, you may be able to pack insulation (such as foam) between the joists. This is a fairly affordable option. Another option is to install insulation between the floor base and the floorboards or carpet. If you have an attic space that you can access, consider adding insulation here too.

Seal Your Windows – A lot of heat is lost through windows, often through small cracks and gaps. Sealing these is a cheap and effective way to save energy.

Use Door Snakes – A lot of heat is also lost underneath doors. Door snakes are cheap and a really great way to stop air passing between rooms – inside or outside. Grab yourself a few and use them where necessary.

Change Your Lightbulbs – Energy efficient light bulbs are a slightly larger investment when you buy them, but they will save you money in the long run. Halogen bulbs, compact fluorescent lamps (CFLs) and LEDs are all better options than incandescent bulbs.

Switch off Power When It Is Not In Use – Pretty obvious tip, right? Chargers for mobile phones and computers, lamps, televisions and appliances – all consume energy. Even they are not in use. It’s not much, but it can amount to a fair portion of your energy bill for a big home. Switch off power when not in use.

Wash Your Clothes With Cold Water – Using warm water to wash your clothes can consume a significant energy amount. Always use cold water unless necessary.

Take Showers Not Baths – A large portion of households’ energy is for heating the water used for bathing and showering. Showering uses significantly less water than bathing and is a far more energy-efficient option. When you do take a shower, keep it short. On a similar note, try and limit all running hot water, such as brushing your teeth, cleaning your face or wet shaving.

Close Your Doors – If you have a large house, it is important to consider “zoning” – closing doors where possible to trap in heat or coolness. If you have a door that leads to a garage or laundry, keep it closed!

Turn off Your Lights – This is energy cost-saving 101. Please turn off the lights whenever they are not in use.

Dry Clothes Naturally Instead of Using a Dryer – Even in winter, sun drying clothes is fine, even if it takes a little longer. Avoid using your dryer where possible. Electric dryers are one of the main culprits to hefty electricity bills.

Close Curtain on Hot Days – Closing curtains on hot days can help keep out sunlight and trap in cool air.

Buy Energy Efficient Appliances – All modern appliances have an energy star rating displayed on the front. Buy the most efficient one you can afford – the more stars, the better. If you want to know more about how this system works, check out our guide here.

Keep Your Air Conditioning Unit In Top ConditionRegularly maintaining your AC system will help ensure it runs at maximum efficiency.

If you follow these 14 tips to the best of your situation, not only will your house be energy efficient… your electricity bill will be significantly reduced as well.

Regassing Your Air Conditioning Unit: A complete guide

By | Air Conditioning

Although relatively uncommon, re-gassing is one of the key processes involved with air conditioning maintenance and repairs. If installed correctly, an AC unit should not usually have to be regassed. However, older units or those that weren’t installed by a professional installer may need to be assessed and serviced. This involves checking for refrigerant leaks, fixing a leak if present, and replacing refrigerant if required.

AC refrigerantAlthough a properly installed AC unit should not leak any refrigerant, it may need regassing at some point. Here’s what you need to know.

What Is Air Conditioning Refrigerant?

Simply put, the refrigerant is the substance that ‘conditions’ the air it blows. Without refrigerant, air conditioners, fridges or freezers wouldn’t exist. It is a compound, either fluid or gas, that creates hot and cold air when combined with compressors and evaporators.

Over the years, the common refrigerants used for air conditioning have changed in favour of new developments. Older refrigerants may be chlorofluorocarbons or hydrochlorofluorocarbons, whereas newer refrigerants are hydrofluorocarbons, which are safer for the environment and offer greater efficiency.

How Does It Work?

In air conditioners, the refrigerant is housed in copper coils. Here they absorb heat and are transformed from a high-pressure gas to a low-pressure liquid. The indoor unit delivers this hot air to the outdoor unit, where it is exhausted.

The refrigerant then cools down, returning to its low-pressure gas form. A fan then blows air onto the cool coils, which then cools the air. This is distributed via the indoor unit. This cycle continues as needed.

Why your unit might need regassing

Air conditioning units shouldn’t have to be regassed if they’ve been installed properly. Professional installers use special ‘flaring’ tools to make extremely tight connections. The pipes used are copper, which is not porous and won’t leak. After installed, the system will then be tested to ensure it is stable and will hold for its lifetime.

The only reason that a unit may need to be regassed is if the pipe connections are not flared or tightened properly, or if the pipes are damaged somehow during their lifetime. However, if you use a trustworthy, professional installer like HunterCON, you can be assured that you will never have to worry about regassing. Not only that, but you’ll be put on our 5-year installation warranty plan. Even if something happens to your AC unit, you won’t have to worry. Youtube to WAV

How Do You Know If You Need To Upgrade Your Refrigerant?

You will probably want to replace your refrigerants if they’re outdated. How do you know? Head outside and take a look at the exterior unit. If it is labelled R12 or R22, it’s time to have your refrigerant replaced. These substances are older and are known to contribute more to the greenhouse gas effect. They’ll also make your AC unit less efficient, which means pricier energy bills. The R22 started being phased out in 2010 and R12 was phased out in the 1990s. Hydrofluorocarbons (HFCs) like R410A and R134 is the standard today.

Filters are an important component of your AC system. They are usually made of fine material like pleated paper or cloth stretched across a sturdy frame.

Their function is to filter the air that passes in and out of your HVAC system. They collect small particles of contaminants that may affect the health and wellbeing of you, your family or your employees, including dust, dirt, pollen, mould, lint and other fibres, bacteria, hair or animal fur, and particles of wood, metal or plastics.

Why Is Cleaning and Replacing Filters So Important?

So why is the cleaning and replacing AC filters so important? Well, there are several reasons. First of all, clogged filters are among the most common causes of major malfunctions in an AC system. A dirty filter will also allow less air to pass through, causing fans to work harder, increasing energy consumption, and slowly damaging your system. Clogged filters can also lead to a buildup of contaminants in your ducts (if you have a ducted system).

How Often Does Your Filter Need Cleaning and Replacing?

Depending on your AC system’s environment, your air filters will need to be inspected every other month and cleaned if you notice they have become quite dirty. It will be quite easy to assess if your filter is too dirty. If your filter looks excessively dirty or damaged in some way, it may need to be replaced. Keep an eye out for any holes, wrinkles or tears – these are telltale signs that your filter needs replacing.

How Should I Clean My Air Conditioner Filters?

Cleaning dirty air conditioning filters isn’t too complicated. The main trick is to be gentle, to avoid damaging or putting a hole in your filter. If this happens, a replacement will be necessary. To clean, wash the filters with warm water, then let them dry before inserting them back into the AC. If the filters are especially filthy, some mild soap detergent will help eliminate potential odours.

Finding the Right Replacement

If your AC filters need replacing, what filter should you go for?

Different filters have different efficiency ratings called MERV ratings – this stands for Minimum Efficiency Reporting Value. In general, the cheaper the filter, the lower the MERV rating. These range from 1-16.

• Filters with a MERV rating of 1-4 are the lowest quality. They provide basic filtration and are the cheapest option. They may be suitable for low-intensity environments.

• Filters with a MERV rating of 5-8 are the next step up, providing good filtration levels at a relatively low cost. They are suitable for smaller systems, such as those in homes.

• Filters with a MERV rating of 9-13 are of higher quality and are more expensive. They can capture tiny particles.

• Filters with a MERV rating of 14-16 are the best you can buy. They can capture minuscule particles as small as 0.3 microns.

Understanding the Energy Star Rating when buying an air conditioner

By | Air Conditioning

Everyone has seen the energy star ratings stuck on the front of appliances, but not everyone knows exactly what they mean. You may shrug these off as being overly technical – but the system is actually quite easy to understand. Let’s take a look!

energy star ratingUnderstanding the energy star rating system is very important when buying an air conditioner. Here’s a look at how it works.

Why Are The Stars There and Where Did They Come From?

The energy star rating system is a joint government and industry initiative that was established to help consumers make more informed decisions about how energy efficient the products they were buying are. By increasing awareness and transparency about energy consumption, the program also succeeded in increasing demand for more efficient products, thus driving the quality and environmental sustainability of the technology.

The system was introduced in the late 1980s, first in New South Wales and Victoria. It wasn’t until 1992, however, that it became compulsory for products sold all around the country. This was when it became regulated by the Australian government.

Is the Energy Star Rating System the Same For All Appliances?

You will have seen the energy rating sticker on everything from fridges to dishwashers to air conditioners. But are they all the same? The answer is no. Why? The most simple explanation is that every appliance uses energy differently – a 4-star AC unit will not consume the same amount of energy as a 4-star TV.

What Does The Energy Star Rating On An Air Conditioner Mean?

You may have noticed that the rating system on air conditioning systems are a little harder to read because they have two stickers – one for heating and one for cooling (if the unit is a cooling only device, and then it will only have a blue sticker).

As you may have guessed, the more stars, the more energy-efficient the unit is. The maximum possible rating for each side is 10 stars. If the product is rated above 6 stars for heating or cooling, it will show a ‘super efficiency rating’, which goes up to 4 stars (6 + 4 = 10).

However, there is more to it than this. Not all air conditioners are the same: some are larger than others and require more power. So how do you compare the star rating relative to other units? You look at the numbers below each rating system.

These are the capacity output and power input readings – basically how much heating and cooling the unit can produce and how much power it needs to run respectively. When comparing a star rating, you’ll want to be comparing systems that have similar capacity output and power input readings.

So How Do You Choose The Right System?

This may all seem a little confusing, especially when you throw money into the mix. Obviously, you will want to choose the most energy-efficient system possible, but this will also mean spending more money. So how do you choose the right system?

It’s important to remember that units with lower ratings aren’t poor quality units. For a product to be rated at all, it needs to pass rigorous efficiency tests, so the base rating of 1 star is actually quite efficient. It only gets better from there. So it’s really up to you!

From experience to credentials, here are 6 telltale signs to indicate you’re working with a trusty air conditioning maintenance provider.

A reliable air conditioning unit comes from working with a good air conditioning maintenance provider. But what makes an air conditioning maintenance provider good? To help you make the right choice, here are six traits or skills worth considering.

Are They Full-Service AC Specialists?

When it comes to choosing an air conditioning maintenance provider, you’ll want to look at their skill set. The best provider will have a wide range of skills, not limited to maintenance alone.

Here at HunterCON, we offer a wide range of AC services, as well as electrical and security services. We have a wealth of experience with systems of all kinds, so no matter the size of the job, we can help. Here are just a few of the processes involved with servicing your system:

• Filter maintenance

• Electrical component test
• Check insulation on refrigeration lines
• System operation
• Inspecting electrical connections
• Thermostat operation

Are They Familiar With Your Unit?

Although most AC systems are quite similar, they do have their nuances. You’ll want to ensure you employ a maintenance provider who knows your unit inside and out, regardless of whether it’s a residential split system or a commercial ducted system.

We are air conditioning experts with a thorough understanding of all kinds of systems. We work with all major air conditioning brands and know every model.

• Daikin
• LG
• Actron Air

Are They Licensed?

As with any trade, it’s important to work with a certified AC maintenance provider to ensure peace of mind throughout the entire job. Licensed AC specialists carry an ARCtick number, meaning they are qualified to handle the dangerous materials involved with air conditioning units.

This also means they are fully qualified to advise on how the system works, general upkeep, formulate preventative maintenance plans and service your system when it needs it.

Do They Provide Preventative Maintenance Programs?

The best AC maintenance providers are those that have the option to include you in their preventative maintenance program as part of their service. A preventative plan for your air conditioning system will help ensure long life and reliable system. If HunterCON installed your AC unit, you’d automatically be put into this program, which comes with an additional 5-year warranty.

We specialise in tailoring preventative maintenance plans specific to the needs of you and your air conditioning system. This will increase the efficiency and reliability of your system, ultimately leading to a reduction in repair costs, lower electricity bills, and an increase in its lifespan.

How Well Do They Communicate?

The best maintenance providers are those that communicate clearly, right from the first phone call. Experience is evident in how well a service provider can articulate, so be sure to ask plenty of questions when choosing a provider.

We pride ourselves on putting relationships with our customers first, no matter the size of the job. Having a nimble team means we can offer ongoing support to all of our clients and see that you always know who you are talking to.

Are They Local?

Air conditioning maintenance is all about speed and efficiency, therefore working with a local specialist is very important. Some AC breakdowns are considered emergencies, and will require attention right away – you don’t want to be left in the lurch by a provider who is based on the other side of Sydney.

We are based in the Inner West. However, our operations span the greater metro area, including the Eastern Suburbs, Lower North Shore and South West. We always respond quickly and aim to be on-site as soon as possible.
