What does air conditioning maintenance consists of?

Air conditioning maintenance refers to checking its components, such as the drain pipes, main unit, and supply lines to make sure they are clean. In addition, the proper operation of the compressor is verified, the status of the filters is seen, the correct operation of the coils and heat exchangers are checked, among other assessments

How periodically should an air con be serviced?

Residential ACs must be reviewed annually, while commercial ACs, quarterly or monthly (as in the case of nursing homes and health centres), depending on the type of building, the manufacturer’s instructions and the corresponding legal provisions. However, in most cases, it is necessary to carry out air conditioning maintenance at least once a year for the equipment to function properly and prolong its useful life. In addition, by regularly servicing an air conditioner, it is possible to find potential faults in it and correct them promptly before the damage (and the cost of repair) is greater.

Can an air con get damaged if it is not serviced as required?

Yes, if ACs aren’t serviced in the period recommended by each manufacturer, the following occurs:

  • The equipment will work excessively and generate a greater amount of carbon dioxide.
  • The life of the AC may decrease.
  • Roofs may flood and create water leaks.
  • The airflow emitted by the device could decrease, in addition to having bad odours caused by mould and bacteria, which can also cause allergies, asthma and other respiratory problems.
  • It can become clogged, reducing its ability to emit heat or cold.
  • Its warranty could be annulled.

What can I do with a noisy AC?

  • Check that the noise is not caused by vibrations.
  • Place the AC in an appropriate place.
  • In case the AC is installed in a wall, the noise reverberates through the structure of the building so it is recommended to move the AC.
  • Check if the compressor is making more noise than usual.
  • Check that the AC is properly installed and put rubber items between it and your property.

Isolate the AC by means of a wall that allows it to maintain airflow and reduce the noise level.

How should a new AC be serviced?

In any case, the right person to carry out the maintenance has to be a professional in the area. They know exactly how to maintain each type of air conditioner.

What any user can do is regularly clean AC filters in order to avoid the accumulation of external agents in them because that may limit airflow and reduce the AC’s operation.

The steps to remove the front panel and reach indoor unit filters should be indicated in each AC’s proprietary manual.

When should AC filters be cleaned?

The filters in the AC indoor unit should be cleaned fortnightly. Now, in case your AC is located in a place where there is a lot of dust or pollution, you should clean it weekly or every ten days at least.

The efficiency of an AC will depend on its filters’ state. If these are clogged by dirt, they should be replaced by neat ones.

Is it necessary to periodically re-gas an AC?

If an AC is installed properly, you will not need to re-gas it.

Pipe joints must be adequately coupled to avoid problems such as pipe wear or other unforeseen causes. If this is not correct, there can be refrigerant leaks in your AC that would eventually make it necessary to re-gas the unit.

It should be noted that aircon professionals are the only individuals who are qualified to check and correct ACs gas leaks.

What are some signs that you need air conditioning maintenance?

Gas leaks

When the air con refrigerant spills, it must be solved immediately. Otherwise, it could cause health damage to users.

Unexpected Noises and Unpleasant Odors

When the AC presents infrequent noises it should be checked. The AC has to be turned off immediately when the sound of metal scraping is heard, as leaving it to operate in these conditions could cause it to eventually get damaged.

On the other hand, when the air conditioner smells musty, there is probably mould in the ducts, and if it smells like burnt plastic, it may be due to the AC cable coating is burning.

AC does not cool

If the air con is not cooling the area, it is necessary to call a professional to service or repair it. If the thermostat has the lowest temperature and the AC emits hot air through its vents, the compressor is faulty. On the other hand, the AC may not cool because it needs to be regassed.

An increase in AC Temperature

If your AC’s temperature is increased, it is possible that the unit has damaged components, dirty coils, or needs regassing.

AC blows less than usual

There are several reasons that can cause less air to blow:

  • Blocked filters
  • Blocked ducts
  • Compressor failure

It is important to emphasize that a professional in the area is the best person to detect the faults for which your equipment does not work well and the only one who can do air conditioning maintenance or repair it if necessary.
