How do I determine the humidifier wire for the furnace control module hook up with two wires the same color?

Hi, I have to get my central air conditioning unit disconnected and shifted to get the pavement underneath it repaired. Also need to get it connected again. How much should the service charge me? One estimate was $1100 which is far too much. Can anyone suggest or comment? Thank you

I have a Rheem central air conditioner unit which suddenly stopped blowing cool air (AC). The outside unit (compressor) seems to be working since it kicks on. However, the air blowing inside the house is only room temperature air. I made sure the blades were turning in the right direction on the...

I need to replace my home air conditioning system. Nice down stairs but upstairs terrible. It's the original system, 19 years old. My house is 2500 sq feet, 2 story. What's the best system I should buy? How many seer? I don't want to overbuy but upstairs is unbearable!!

My central air unit does not "kick" on. The fan from the furnace and heat... does. There is a spark at the thermostat and the fuse box appears to be o.k. Any suggestions.
