Lately when I try to turn off our central a/c I have been dealing with some concerns. It seems it is taking a while for the control unit to react and link with the central heating and a/c. Periodically our central a/c can take up to 5 minutes to shut off. It was getting pretty annoying. I finally decided to call the local heating and a/c contractor to have them send out a certified heat and cooling system specialist to see what was going on with the control unit and our central heating and cooling system. To find out why when I have been trying to turn off our a/c it is taking that long. Well, I found out that the issue was that the condenser in the Heating plus Air Conditioning idea was on its way out! That is what was causing the concerns all along. I had to pay a little extra to have the heating and cooling specialist from the local heating and a/c contractor update the condenser. But now everything is working normal again. My central heating and a/c idea now turns off when I honestly flip the control unit to turn it off. I wish I had known this sooner or I would have called the heating and a/c contractor immediately to repair this Heating plus Air Conditioning issue. At least now I guess if it ever happens again why it is happening and I will be able to act immediately and get the condenser updated if needed.
