What If My Air Conditioning Unit Stops Working after Thermostat Change?
If you have already eliminated the thermostat as the source of trouble, there are few other things you can checkwhen the air conditioner stops working. Begin with the condenser. These components sometimes get blocked by weeds and grass or they may be dirty from debris or dust that has been blown into them. Give the condenser a thorough cleaning. If this doesn’t resolve the issue, try cleaning the evaporator which could also be dirty.
Some air conditioning issues should be treated only by professionals. These include a faulty compressor or motor, a lack of refrigerant, and an improperly sized air conditioner. If the thermostat is not the problem and cleaning your air conditioner hasn’t helped, then your next step should be to call in a professional.Four Common Signs You Need Heat Pump Repair » « Can I Troubleshoot My Home Furnace on My Own?
