Question about Coleman Heating & Cooling
The first thing I would do is to make sure that you have power to your outside unit. The main power coming in should be 220-240. The power in should go directly into the contactor which shoul have two lines from the thermostat to bring 24 volts in to engage contactor.Without knowing what has already been done it's possible that he took power from the transformer on condensor to power gas valve to get you heat. If this is the case then you will need to get 24 volts back to contactor to make your a/c work.Hope this helps you some. Thank you.
