Did you know that in the U.S., buildings account for 76% of the nation’s entire electricity use? Or that 35% of their energy use goes only toward heating, ventilation, and air conditioning?
It’s no wonder then that business in Texas paid an average of $624.56 a month for their electricity bills in 2017! If your HVAC unit, however, isn't in tip-top condition, you can be paying much more.
This is why regular commercial HVAC maintenance is key to keeping energy bills low. Besides, proper maintenance will ensure your AC can beat the heat this summer. Especially in Southern Texas, including Waco, where temperatures may go over 100 °F.
That said, it's best you go through this HVAC maintenance checklist ASAP. This way, everyone in your building keeps cool while also avoiding heat exhaustion!
Replace (or Wash) the Filter
The first (and easiest) step to HVAC preventative maintenance is changing its filter. This is also one of the few steps you can do on your own to clean your HVAC before summer. Depending on the unit, the filter can either be replaceable or washable.
What’s important is to get rid of accumulated dirt and debris in the filter. Filth in the filter restricts your heater's or cooler's ability to blow out warm or cool air. Also, letting your filter get clogged can mean having the HVAC recirculate dirt in the indoor air.
Replace or wash your HVAC filters at least once every two months. Once a month, if your building is within a dusty area (like near busy roads).
Check Level of Refrigerant
Low refrigerant levels in the AC can lead to a commercial HVAC unit not "cooling" enough. In fact, if there's a refrigerant leak, your AC may not blow out cool air at all.
As part of your HVAC maintenance, have a technician check the unit's refrigerant level. It may need a recharge or there may be a leak that needs repairs.
Clean and Adjust Fan and Blower
The fan or blower in an HVAC system is what moves the conditioned air into a space (AKA your building). Dirt and debris accumulate on these parts, and when they do, they decrease air flow. This not only reduces HVAC efficiency but can also cause the AC to freeze up.
That's why cleaning these parts is key to your HVAC preventative maintenance checklist. Also, be sure to have the fan or blower adjusted to ensure optimal air movement.
Clear Filth and Debris from Evaporator Coils and Condenser Pans
The evaporator in an HVAC system "collects" heat from the air inside a building. Whereas the condenser brings this heat outside of the building.
Problems can start when evaporator coils freeze or when condenser pans get clogged. These can cause issues like poor airflow, warm air out of the AC vents, or mold-like odors.
Maintaining condenser pans is easy -- just clean and drain them. Cleaning evaporator coils can prevent them from freezing but may be too tricky to DIY. It's best that you let expert HVAC technicians handle this part of the maintenance.
Regular Commercial HVAC Maintenance Help Avert More Serious Unit Damages
Keep in mind that in Texas, the average cost of central AC installation is $6,032. But you wouldn't need to worry about that huge cost if you take care of your existing HVAC in the first place. It's much more affordable to have professionals conduct commercial HVAC maintenance.
They'll also tighten the unit’s electrical connections and lubricate its moving parts. All these are crucial steps to keeping your HVAC unit's efficient performance.
