If you own a business, you'll need to understand that a commercial air conditioning system is much larger and uses much more electricity than a residential system. Because of this, it is important that you do proper maintenance for the commercial air conditioning unit. The unit can still have problems, however, two of which are listed below. If you notice these problems, you should get your unit fixed so you and your employees will stay cool.
Commercial Air Conditioning Unit Will Not Turn On
If you walk in and the air conditioning unit is turned off and will not turn back on, this may be a problem with the fuse that controls your unit. Change this fuse first and see if the air conditioning unit will turn on. If it does not, there may be a loose connection or broken wires in the electrical wiring.
If there is ice built up on the condenser coils or anywhere else inside the unit, the air conditioning unit may not turn on. If this is the case, the ice will have to be melted. The motor for the unit may be bad and need to be replaced, or the compressor could not be working.
If there is a lot of dirty buildup inside the unit, this may cause a complete breakdown over time. If the air conditioning has no refrigerant, it may not turn on.
Commercial Air Conditioning Unit Will Not Cool
If your commercial air conditioning unit will not cool, first check the temperature set on the thermostat. The thermostat itself may be bad if it keeps showing the wrong temperature. If the thermostat is set at the right temperature, the compressor belt may be loose or broken. If the compressor belt has too much oil on it, this will cause the belt to slip.
The unit may not have enough refrigerant. If this is the case, the refrigerant may be leaking. The condenser filter may be clogged. If so, the condenser cannot cool the air properly. Check the fan inside the unit to ensure it is running well. The fan blades may be bent or covered in debris.
Contact a commercial HVAC contractor to come to your business to determine what the problem is. They can then repair the unit for you, so you can have cool air again. While the contractor is, there ask them to show you maintenance tips you should know about so you can keep the unit running well.
