My air conditioner has stopped working. Is there anything I can check before I call for service?
Yes, a homeowner can easily make the following checks: Change the batteries in your thermostat. If your thermostat has batteries in it, try swapping them for a fresh set. If your thermostat is not battery powered, do not install batteries in the thermostat.Check the circuit breaker. Has the circuit breaker tripped or is it off? If you find it tripped, reset it and see if operation resumes. If the circuit breaker trips a second time you will need a service call to determine the cause. Do not reset the breaker more than twice as unit damage may occur!Change your filter. Your HVAC system needs to move a certain amount of air to function properly. If your filter becomes restrictive, even slightly, your system performance and efficiency will suffer greatly. Changing your filter regularly is cheap insurance for your system and keeps your homes air cleaner!
