Question DetailsAsked on 12/1/2015

how much to fix heat pump with compressor that is not charging?

I switched out thermostat but wired it wrong. Had a pro family member wire it properly. The fan outside now works as well as the aux heat but the compressor on heat pump no longer "charges". I had wired mixed up the orange with the W2.

Sounds like you need a Heating and A/C contractor. Since fan comes on and auxiliary heat, sounds like the thermostat was not damaged. Compressor not coming on means either the thermostat is not set to A/C (did it get switched to OFF or Heat ?), or perhaps the control board on the A/C unit got fried - no way to tell without taking a volt ohm meter to it and checking where it is and isn't getting current. I seriously doubt the A/C mechanical unit itself was damaged - sounds like just a control circuitry issue - not that those cannot be expensive too.

Other possibility - that the "pro" family member wired it wrong again, and the thermostat thinks you are calling for heat when you think you are calling for A/C. That would be my first thing to check for.

I would guess minimum service charge of probably $75-150 if miswiring, maybe a few hundred $ if board got fried - a lot of them cost around $100 for the board itself, though they also go up to the $300-400 range for some models.
