Lennox Air Conditioner not working at all after winter
Hi,
Our central air conditioning (Lennox) is not working at all. It was working fine last year when we tuned it off. A.C. is almost 3 yrs. Old. We have checked everything we know, like thermostat set up, circuit breakers, reset button and resetting of power supply plug close to outside unit etc. Our furnace is working fine and blower fan too but we turn the thermostat to cool with temperature set lower than room temperature, even blower fan don't turn on. We don't know a lot about air conditioning and not sure whether furnace breaker in the circuit box should be on or off. We will really appreciate if someone can help. Thank you, Hennah |
