    You may need to get a service person in the recharge your system with freon. How old is it, and when was the last time it was serviced?

Sounds like a bad or stuck reversing valve. Typically r.vs. are energized in cooling, verify 24 volts to valve, if yes , bad valve

My heat unit will not blow hot air unless we go outside and hit a button on the back bottom of the unit. Once we do that it will blow hot air for that cycle. when it is time for it to come on it is cold...


If it does not have a furnace or heating elements for heating, then it is a heat pump, which is rare for a central AC system, but makes sense of the fact that it blows warm air when you reset the pressure switch, which may indicates freon pressure charge problem if your AC system has a reverse valve and uses freon to for heating (heat Pump).

Do you get heating when outside unit runs? if you do, check freon pressure levels and top up to required pressures. The button you depress is a pressure reset switch ... that is if your AC system is a heat pump ... which, as pointed above, it is not common for central ACs.

Ac BLOWING HOT AIR INSTEAD OF COLD. All of a sudden my AC started blowing hot air instead of cold. It is set on cool.


Check to see if your outside unit is running. If not, check the breaker. If it is running you may have an issue with the reversing valve. It looks like three lines coming out of the top and one on the bottom. Trace the wires back to see that they are tight and secure. Of course, TURN OFF THE POWER first. good luck.
