You are probably going to have to call a Hi Vac repair as your freon is probably too low to operate your Heat Pump properly. The only difference between the Air condition side and the heat side is a reversing valve that takes the heat produced by the Air Conditioning (cold) side and sends it into your house and exhaust the cold air out side. If the pump cannot produce heat from the expansion and compression of the freon, then no heat. You may also want to check that the pump is running as it is protected by two large BUSS fuses on the AC power to the heat pump and if any one or both of those fuses are blown, then no power to the Heat Pump. There should be an 8 inch square box mounted on a wall next to the heat pump that supplies 220V to the pump.

My 19 ft airstream's Penguin duo-therm a/c unit just started blowing out HOT air!!!! Why is this occurring?


If you have a heatpump model a/c unit, and it is blowing air that is hotter than the ambient temperature inside the airstream, then it is likely that your reversing valve is stuck in the open or closed position. A heatpump is basically an air conditioner that will also run in reverse (via the reversing valve) in order to heat instead of cool. The valve can get stuck for a variety of reasons, including; faulty wiring caused by rodents chewing or vibrations, insulators (dirt) between switch surfaces, or it could be a mechanical problem within the valve its self; these valves break often.

Heatpump blow out air put not warm


We will need to check and see if the outdoor unit is running when thermostat is set for heat. If not, check the circuit breakers and reset if tripped. Also, check to ensure the high pressure switch isn't tripped (you will likely need to open the panel to see the HPS, it will have a red button on the top of it.

Heat side of heatpump is blowing a transformer when switched to heating mode.


It is either a shorted wire or a shorted component in the heat cycle wiring. The most likely is a bad reversing valve solenoid. You can use a re-settable transformer to help lower cost while troubleshooting. Remove the RV solenoid wires and set the unit for heat. If nothing blows,you will have found the problem. If it is not the RV,plug it back in and remove another low voltage wire and restart the unit. Keep doing this until the unit runs. When it runs OK,the last wire removed will go to the defective part.

Mitsubishi heatpump not blowing out heat.


One reason could be a shortage of refrigerant. Another could be incorrect mode selection? Or the reverse valve which changes the unit from cooling to heating is either not being energised or may be blocked and would have to be replaced.

AC/Heatpump units cycle numerous times blowing ambient air.


If the compressor never kicks in, I would check the start capacitor, thermostat and the compressor windings. Most times the start capacitor is defective. Some window air conditioners the fan will run while the compressor stop through the thermostat switch. If the thermostat switch is bad every thing runs except the compressor. Let me know, Thanks, Sea Breeze

Change your heating delay to shut off sooner, you can find this in the installation manual. Also the Thermostat may have delay after heat as well. It is true there could be many variables, but it also sounds like the Heatpump is not charged properly, you will have to have a different tech come out and check that. No need to have the installer mess your system up any further. This solution will only correct the auxilary heat, your heat pump on the other hand will require expert skills.

If your Heatpump's fan isn't running but your compressor is, your fan motor is out. If nothings happening at all ensure your getting power to heatpump (ex: breaker tripped, fuses blown on outside power switch, or fuses blown in breaker box?)

Low heat


if this is a heat pump it should either be low on freon or problem with airflow over outdoorcoil. (like a fan that failed or really dirty coil) PLEASE keep in mind if this is your first year with a heatpump instead of a furnace it does blow air out MUCH colder than a gas furnace or boiler.
Thanks ,

Heat pump is not kicking in, no heat at 42 degree outdoor temp


HI,

Most likely has a freon leak , or a control problem causing heat to turn on, or if you have a heatpump the reversing valve has a problem.
