We had the same problem and then had to pay $60 to have the guys who installed our original system tell us we just had the settings wrong. We thought we had "electric heat/cool", which is what we set the thermostat for. Turns out we have "auxhilary heat pump" or something like that. We don't have gas heat, it's electric, but apparently its not basic "electric heat/cool". So try changing your settings. Good luck!

Furnace switches to auxiliary heat while in cool


It's likely a bad tstat. Turn the power off to your air handler. Remove red , green, yellow and orange wires inside the tstat and wire nut them together. Not sure if your reversing valve energizes in heating or cooling but, turn the power back on. If the unit is heating turn the power off and remove just the orange wire and turn power back on. Let this run and see if it you are ONLY getting cool air ALL the time. If so you have a bad stat. If still getting heat possibly you have a bad control board in the air handler. Good Luck!!

Hello, When I set my AC unit to "Heat" and turn it on, the air will come out warm, then after a few hours the air starts to come out cool. To make it warm again I need to set the...


It sounds like you have a heat pump. When you first turn on the system the heat strips will come on and produce warm heat (referred to as supplemental heat strips), as temperatures rise the heat strips will turn off and the "A" coil will just exchange heat to maintain temperature thus conserving energy. . Initially the temps will be around 125 degrees at the register, and drop down to about 105 after the strips turn off.

On some TXV controlled outdoor condensing units the Thermostatic Expansion Valve will stick in the cool position and require replacement this will cause this symptom. It takes several hours to do and requires a licensed technician to do as it involves recovery of refrigerants. I hope this helps

I am getting hot air instead of cool air from my heat pump when it is in the cooling mode.


The problem is in the thermostat wiring. Y1 on an air conditioner, brings on the cooling. On a heat pump, it brings on the compressor, which generally fails to heat mode. The O wire operates the reversing valve, which brings on cooling. If these wires are reversed, or not hooked up, you will not get cooling.

No heat coming out but everything appears to be working fine, low on refrigerant but not empty. Turning on and operation light is on but no heat or cool air.


Heating/Cooling capacity of a system is affected by an improper refrigerant level. Though it still has refrigerant in it, it needs to be properly charged to the manufacturer's specifications. Good Luck. :-)

No heat changed thermostat flushed engine new coolant


did you release air from cooling system when replacing coolant!! if air is trapped in system it will not heat up proper. turn fan on high heat locate bleeder for cooling system, open bleeder with car running. if there is any air in system you will see it come out of bleeder. keep checking for heat. when you get heat bring coolant to proper level. leave top off of coolant recovery tank while bleeding system. put cap back on when done.

A/C turns on and cools but Heating system does not turn on when switched fron a/c to heat. All I hear is a click form the heating system.


Depending on whether you have a gas or elec. heating system it could be a fan control module or a heat sequencer. It's not the thermostat since it is clicking calling for heat. It's not the blower motor because it comes on during cooling. Either way it's an inexpensive repair.
