The Connection of Heat Pump

The air discharged by heat pumps is not as hot as by oil or gas furnaces. Fire furnaces have a natural ingredient of heating as compared with heat pumps. However, if your heats pump is discharging less heat than usual. Following measures can be taken:

  • Raise the temperature by 5 degrees F and wait for a while to work it
  • Make it sure that room heating function is turned ON
  • If heat pump filters are covered with dust make them clean
  • Clean the outer coils of the heat pump


It is commonly seen that in really cold weather, condenser unit of heat pump gets frozen. To keep it working defrost cycle system must be checked after short periods of time. Check for the dust, ice crystals or any other thing that may cause blockage of heat pump filters. If no such thing is found then proper services of professionals can be hired by calling local HVAC Contractor near you.


In really cold weather heat pumps need the power to make its machinery in working condition. For this purpose, heat pumps have a built-in function which turns them ON automatically. Due to this function, the power breaker may get tripped. Check the circuit breaker and turn it ON again.


The problem in a blower of heat pump can be caused either by limit switch which distributes air to all particles. When air gets too hot, limit switch will shut the blower down. To fix this, check the thermostat to turn the fan ON or keep it at auto. You can get some help from user manual to adjust the speed of fan.

The other cause may be the disconnection of motor and belt. If the belt has been broken then the motor will run but the blower will not work. There is no hectic in fixing a broken belt. Just do the following:

  • Remove the door of the heat pump. Take the belt outside. Note down the number of belts stamped on it and replace it with a new one.
  • If the belt is in good condition. It can be placed properly, first on motor’s pulley and another side on the blower’s pulley. But keep your hands safe while doing this.


If there is a blockage on the filter of the heat pump. It will not let the blower work correctly. So make it clean. The other reason can be up and down in temperature, which is not measurable by the thermostat. Place the thermostat somewhere else or set the temperature correctly.
