Parts Of Your Commercial AC That Need Regular Cleaning And Repairs

Posted on

If your HVAC unit is on top of your building, it's subject to intense sun, blowing dust, and violent weather. It's always a good idea to check your HVAC regularly so repairs can be made to damage caused by the harsh conditions and to clean out the unit.

Keeping a commercial air conditioning system clean is important for the operation of the HVAC and for air quality in the building. Here are some parts that may be cleaned and repairs that may be necessary due to clogs caused by dirt and debris.

The Filters

Your building maintenance crew or your HVAC service should change the filters regularly, and this could be once a month. This is important because the filters keep dust, mold, and other debris out of the air conditioning unit.

When the filter is clogged, the air is restricted as it's pulled through the filter. This causes the air conditioner to overheat and shut off. The result is a hot building and employees complaining about the air conditioning. Changing the filters out regularly is an important part of maintaining your air conditioner that can help reduce the need for repairs.

Evaporator Coils

The evaporator coils in the air conditioner slowly accumulate dust. The commercial HVAC technician cleans the coils when needed so that the dust doesn't become a problem.

However, if you don't change the filter regularly, then more dust than usual will get inside the HVAC and cling to the evaporator coils. This interferes with the ability of the AC to cool air for your building.

One problem that could develop due to dirty coils is that the air conditioner ices over and shuts down. This could leave your employees without cool air until the situation can be repaired.

Drain Lines

A commercial HVAC system is large and complex for a big building. There are different zones that have their own equipment and drains.

A commercial system has several drains, and they're all vulnerable to clogging. When a drain clogs off, water collects in the drain pan until it overflows. This situation needs to be repaired, and it's done by cleaning out the drains so that condensation can flow out of them freely again.


Your building has a maze of ducts that deliver cool air to your employees in different parts of the building. If dust is allowed to accumulate in the ducts, or if mold grows in them, your employees may start coughing or sneezing.

The air quality in your building suffers when the ducts are dirty, but fortunately, they can be cleaned out. Dust, mold, and even rodent debris can be removed and the ducts sanitized, if necessary, so that the air quality improves in your building.

Keeping the HVAC clean helps it work better and avoid breakdowns, but there are still times when something will go wrong with your AC. A hole might develop in a refrigerant line or a blower might go bad. In that case, you'll want to have a commercial air conditioning repair service such as Day's Appliance Repair Heating & Air Conditioning Co come right away so your employees can cool down and focus on their work rather than be distracted by hot and muggy working conditions.
