I had this company do a service on my air conditioning recently. The tech told me that my heat exchanger had a crack in it and the whole system needed replacing. Apparently the heat exchanger is the compartment where the heating takes place. The tech said he wanted a second oppinion so he had his supervisor come out and look at it. They both agreed i needed a new unit. Anyways, something didnt sound right with there diagnosis. The cost to replace the unit was ridiculous. I called another company to give me a second opinion. This company could not find anything wrong with the unit. They took the whole unit apart so i could take pictures. The heat exchanger looked brand new. Upon calling Pac Air for an explanation they stated that sometimes their guys can overlook things..! You kidding me? Anyhow, hope this helps you!
