Having problems with your Air Conditioners ?

I have power running to the indoor units but the heat pump and the indicator lights are not comming on. It's like there is no signal from the heat pump got any ideas?


Answers :

Have you checked the breaker to the outdoor unit? Have you checked to see if your indoor unit is calling for it to come on? You will need to do a complete breakdown on the unit to see if the two are communicating with each other. It could be the control board outside.

Now, there is a clicking noise coming from the heat pump - it did it at first when trying to turn it on....now, when it's warmer, it will turn on, then start to do it. Doesn't seem to be putting out hot air now. Any ideas? The thermostat came with a new box that sits inside the ceiling and it's been replaced, bu
