Is maintenance required for commercial air con?
In most cases, yes, but not for the first reasons that might come to mind. Required maintenance comes down to the laws set Essential Fire Safety Measures. Clogged ventilation or parts in disrepair can be a hazard to tenants and need to be prevented. This service is typically conducted on a quarterly basis unless there are special regulations for your industry. The upside is that regular commercial maintenance will also help with system efficiency and reduced utility costs over time.
Are there other options aside from VRV/VRF for commercial AC?
Smaller commercial spaces may be able to make use of either single split or multi-split ductless systems. These can give you better temperature control per room but include many more exposed vents and filters that require upkeep.
Does it matter if our commercial air con is too big for our space?
Actually, yes. You might think that a bigger system is a good thing when it comes to cooling a space. But commercial air conditioners should be right sized for the space they support. An oversized system will create too much moisture and leave things feeling a bit more humid. Likewise, if your system is too small, it will struggle to cool the space, creating energy inefficiencies and leaving everything uncomfortably warm.
How can I save on energy while still keeping customers and employees comfortable?
Having a commercial air conditioning system that is sized properly for your space is a good start, as noted above. Routine commercial maintenance is also important since it will keep the units running as efficiently as possible.
You might be tempted to run your system as little as possible in warmer weather. But if you start cooling the space before it heats up throughout the day, you’ll actually need to run the system less overall. It will simply struggle to catch up and cool things off if you wait to turn it on when the midday sun hits.
