FAQ's Do you charge to test my A/c? Why is my A/c blowing hot/warm air? What’s wrong with it? My A/c doesn’t work, how much will it cost to fix and how long will it take? Why can’t you only replace the A/c Compressor and skip the receiver dryer and TX valve? Why can’t you use 2nd hand parts for the repair? If my air conditioning lasts for the summer I just have it recharged at the beginning of the Summer. Anyone from any repair shop can fix air conditioning. Air conditioning has not changed over the years. Air conditioning fluid (refrigerant) has to be charged every so often.
