I have used Central Heat and Air for 20+ years, but no longer. The last few times I used them it has gotten worse and worse. I would not let this place repair my toaster, much less my AC. The last time I used them was the final straw. They promise to get a part overnight when it actually takes 4-5 days. They repaired my unit, and it was working fine. I walked into my house, and a couple of minutes later I hear a loud pop, and my main breaker had cut off. The workers had shorted something inside the unit. Once they got the power back on the AC unit was NOT working but they refused to accept any responsibility for this. They got the unit running again by bypassing a sensor. I contacted the manufacturer, and was told this "repair" is not authorized or recommended. Central still has the nerve to bill me, not only for the initial work they did, but for the unauthorized repair as well! Central Heat and Air should be avoided if at all possible
