Thermostat malfunctions are often responsible for heat pump failures. This article will help you decide on what to do if your heat pump does not function properly (maybe it does not cool or heat properly, frequently cycles on and off). Highlighted below are the common problems associated with heat pumps as well as the steps to take in troubleshooting them.
Heat Pump Does Not Heat or Cool Properly
Heat pumps do not produce air that is as hot as that produced by gas forced-air furnaces. If you are however used to certain temperatures of air but your heat pump produces cooler, you need to take the following steps:
- Set the thermostat properly.
- Open the room-heating registers.
- If the heat filter pump is dirty, change it.
- If your heat pump has auxiliary heating elements, ensure they are working.
- Be sure that the coils of the outdoor condensing unit are clean.
Heat Pump Becomes Noisy
When you start hearing squealing sounds and grinding noises from your heat pump, the motors bearings may be shot. You need to call the attention of the technician for this. If you are hearing rattling noises, ensure that the cover panels are tightly screwed. You can also insert flexible insulation ductwork in between the heat pump as well as the ductwork runs to reduce noise.
If you notice a popping sound emanating from the ductwork, it may be due to thermal expansion. Track the sound through the duct runs. Once found, make a small dent in the metal to provide a rigid surface that won’t move while it heats and cools.
Heat Pump Freezes or Trips Breaker
Take the following steps to correct this problem:
- Turn off the condenser unit if it freezes up or turns off.
- Ensure that the return-air registers are not blocked.
- Make sure that the filter is not clogged.
The Heat Pump Cycles Incorrectly
The heat pump may turn off and on too frequently if the unit is overheating. This problem may be due to a clogged filter or malfunctioning blower. The best thing to do to correct this problem is to check the thermostat. Ensure that it is properly calibrated. If the temperature in the room is higher or lower than what you set on the thermostat, then the problem may be due to the heat anticipator in the thermostat.
Heat Pump Fails To Run
There is a problem with the thermostat if the heat pump doesn’t go on. The following steps should be taken to troubleshoot:
1) Set the thermostat to the right setting. If you just replaced the thermostat, it’s possible that the new thermostat is the wrong type or it may have wrong wiring.
2) Ensure that the heat pump is receiving power. Go through the main electrical panel as well as any subpanels that provide power to the unit. If any of the circuits has tripped, flip it to OFF and then on kit to reset it. If the problem persists, you need to hire the service of an electrical contractor.
3) If your heat pump is connected to a power switch, ensure you turn it on. Once this is done, wait for few minutes for the handler to engage.
4) Ensure that the fuses that protect the heating elements of your heat pump (if your heat pump has electrical elements) have not tripped.
If after taking these steps the problems persist, you need to hire the service of a technician that is fully adept in the repair of heat pumps. This is where Loveland HVAC Repair comes in. get in touch with us today.
