When you go to turn on your commercial property's AC unit, it might kick on right away. But what if it didn't turn off? That wouldn't be good because then your energy bills will rise and excessive wear could happen to various parts. If you're in this situation, these solutions can help with commercial AC repair.
Check Thermostat Settings
Before thinking about the worst possible scenario with your commercial AC unit, remain calm and first head to the thermostat. You want to check the settings to make sure they're not set to where the AC unit would just keep running.
If the cooling setting is in fact switched to off, then check the fan setting. It could still be on or set to auto, and that could be the reason why the condenser is still running. Turning everything to off can often times solve the problem.
Look For a Faulty Contactor
When you turn the commercial property's AC unit on, electrical signals are sent to a component known as the contactor. This piece then closes and powers up the outside unit.
Every now and then, there can be excessive heat created around the contractor when it engages. This can make it stay closed like a weld. Then the outside unit will just stay running even if you have the AC unit switched off.
If you believe this problem is likely, then hire a commercial repair technician. They need to get the contactor open so that your condenser unit can shut off properly.
Consider Damaged Thermostat Wiring
For your commercial building's AC unit to shut off when disengaged, the thermostat wiring needs to be in great condition. If it's not, then a proper signal can't be sent to the outside unit to turn off.
You don't need to worry if you suspect damaged thermostat wiring . You'll just need to find a commercial HVAC contractor to fix what may be wrong with the wiring.
It could be a punctured wire or wires that have been chewed through by rodents. The contractor will access these wires and test them, seeing which ones need to be repaired or replaced.
Having a commercial AC unit that turns on is always great to see, but when it doesn't turn off, that creates a lot of stress. Even though this isn't an ideal situation, you can handle it by going through possible issues and hiring professionals if there is a severe problem.
