Make sure you give it time. The fan has a time delay in heat mode and doesn't come on until it warms up first.

SOURCE: Ruud heating/ac unit blowing only cold air in heating mode

Do you have gas or electric heat. If you have gas then you do not have a heat pump. You should in most cases have a red,yellow, white, and green wires coming to the thermostat. R should go to rc/rh G should go to green Y should go to Y and w should go to W. Also the switches on back should be switched to non heat pump and gas rather than electric. Hope this helps.

SOURCE: Heat Pump and fan work fine, but will not blow

The reversing valve coil may be bad or no power to it during cool. Most heatpumps are set to have the coil of the reversing valve energize in the cool mode. The heating mode is the fail safe mode if the rev valve fails to energize. Check this and let me know.

SOURCE: My AC unit wont blow the cold air.

No, you probably have a bad evaporative fan motor, capacitor or switching. It usually takes a Pro 1/2 hour to track down such a problem with good training.

SOURCE: I changed my fan motor and squirl cage blower

If you have changed the motor, I assume that the RPM is the same as the motor you have removed.?
Check the rotation of the new motor, if you have it turning in the wrong direction, it does not matter how fast it turns, it will not send enough air across the evaporator and condenser coils.
Also, if you have changed the motor, you should also change the run capacitor for the power motor.
Hope this info has helped you.

Coleman furnace problems


I take you mean there is a fan coming on that blows AC air thru the vents and is the same fan used to blow the heat ? If that is the case is the fan coming on when the heat comes on ? If not then that is why you are not getting the heat.
That can be from a temp sensor not working or a control board or a contactor
First see if the fan even comes on or if the same fan is used for both AC and heat

Ac fan wont blow


I would disconnect the fan connector and use contact cleaner to clean the connection. Usually corrosion. Also fan might be going bad (Common Problem).

The cooled air is coming out at a very weak rate. The ac unit outside is blowing out cool air when the neighbor's is blowing out warm air. The house is just not getting cool. AC has been on for 4 days...


Turn off your A/C and put your fan switch in ON or FAN. Run the fan only for approx 3 hours. Check your air filter and clean/replace as necessary. Also check your evaporator coil and clean if necessary. It is possible that your evaporator coil is frozen up from a dirty filter or coil. If it continues to be a problem, you probably have a refrigerant problem which will require a certified service technician to address. Try taking care of the filter and coil first. :-)
