If your air conditioner is blowing hot air into your commercial business, this can make it difficult for everyone to work, especially if it is hot outside. Fortunately, there are some things you can do on your own to determine what is wrong with the air conditioner. If not, you can contact an air conditioning contractor to repair or replace your air conditioner. Keep reading to see if you can get your air conditioner to start blowing cold air again.
Inspect the Thermostat
The problem may be with your thermostat instead of your air conditioner. First, check for any loose connections or wires under the baseplate of the thermostat. To see this, you will have to unscrew some screws to remove the baseplate. Look for loose wires or look for any wires that are not connected to anything. If you see either of these things, then this is your problem. If it is only one wire, you may be able to repair this on your own. If you still have documentation from your thermostat, it likely has a wiring diagram in it to help you.
If you see nothing wrong, then the actual thermostat may be bad and will have to be replaced.
Check the Condenser Coil
Another thing that can cause an air conditioner to blow hot air is the condenser coil may be dirty. If it is, the condenser coil cannot work properly. To repair this problem the condenser coil must be cleaned. To prevent this from happening in the future, you should have your unit maintained on a regular business by a qualified contractor.
Go outside and look at the unit. You should hear it running. If you do not hear anything then one of the components inside the unit is not working. Because you are feeling hot air the compressor inside the unit is likely bad. The unit may also be running low on refrigerant. If so, a contractor will have to refill the system for you. It could also be a problem with the condenser fan, such as the motor may be bad.
If none of these things repair the problem, you may have a return duct that is not connected. If you do, then this duct would pull hot outside air into your building.
Talk with a contractor, such as at Associated Mechanical Contractors, Inc., about this information and they can give you many more details. The contractor can also give you many tips on how you can care for your unit during the year to keep it running.
