Question about Heating & Cooling
I have a intertherm heatpump that has the heat strips located in the outside unit. The heat pump works ok until the temp gets around freezing then not enough heat to hold the thermostat setting. I suspect the strips should be helping the heat pump but is not. I can manually turn on the emergency heat and get hot air. also there is a cycle when the heat pump blows ice cold air for about 2 minutes while in the heat mode. Hope yoy have some advice. Thanks
FIRST YOUR OUTSIDE UNIT PROVIDES HEAT BY USING A REVERSING VALVE TO CHANGE THE REFRIGERANT FLOW.THERE IS NO HEAT STRIPS OUTSIDE SECOND YOUR EMERGENCY HEAT TURNS ON ELECTRIC ELEMENTS INSIDE YOUR AIRHANDLER UNIT.IT SOUNDS LIKE SOMEONE HAS WIRED YOUR UNIT WRONG OR HAS THE THERMOSTAT SET IMPROPERLY.WHEN THE HEAT PUMP CANNOT SATTISFY THE SETPOINT THE THERMOSTAT IS SUPPOSED TO TURN ON YOUR ELEC. HEAT UNTILL THE LOAD HAS BEEN REACHED AND THE HEAT PUMP CAN CONTINUE TO MAINTAIN IT.

It sounds like you have a packaged unit for modular or manufactured housing. If this is the case I have noticed that they have a outdoor thermostat wired in series that does not allow the heat strips to come on unless it is satisfied at around 55 degrees. Remember this is inside the unit so it could be much colder outside. If this is not the case you may have a defrost problem, either in the defrost board or defrost sensor.
