Heat From Air

The top 5 heat pump problems and solutions.

If you’re looking for an economically clean, financially beneficial heating system that is going to survive the test of time, well then a heat pump might just be the perfect choice for you.

To further help you make that choice, we have outlined our personal top 5 common heat pump problems and the very handy solutions for these issues!

Sudden Loss of Heat.

If your heat pump suddenly stops producing heat, don’t panic. The problem could be something that’s easy to solve such as adjusting the thermostat. Before anything else, this is something to be checked first, ensuring the heat pump is turned on and set to heat. You never know, someone in your property could have intended on temporarily switching the heat pump off, forgetting to switch it back on.

If you recently replaced your thermostat, this could also be the root of the problem. In this case, the thermostat may be the wrong type, or may have been wired/setup incorrectly. Alternatively, if it isn’t the thermostat, the issue could be the lack of power caused by a tripped circuit, so you may need to check and reset the circuit breaker.

If your heat pump is still not working, contact Heat From Air to schedule a call from our expert technicians and we’ll do everything we can to help!

Not Enough Heat.

If you find that your heat pump isn’t warming your home as much as you’d like, then it could be down to a dirty air filter or faulty parts. Just like with an air conditioning unit, reduced airflow decreases system performance and can damage the compressor within the unit.

We definitely recommend inspecting your air filter once a month, especially during the months where you tend to use the heat pump more. It is advised to check your heat pump’s care guide for model-specific instructions on how to replace or clean air filters if this is the case. Or even better, set up regularly maintenance visits to ensure your system is kept in tip-top condition.

Other possible causes of a heat pump’s insufficient heat production may include potentially blocked air ducts, faulty valves, or poor refrigerant flow, all of which we will check on our maintenance visits!

Heat pump problems

Blowing Cold Air.

If you feel cold air coming from your air vents whilst the heat pump’s fan is running, there may be an issue with the system’s thermostat. It’s best to not assume the worst, however. It is possible that a heat pump may go into a short defrost mode to prevent icing up. This means that there could be an output of cold air, but only temporarily.

However, if your heat pump is producing cooler air than usual, try setting the thermostat to emergency heat to see if warm air flows out the vents. If you do feel warm air, then the issue is with the outdoor unit. If not, you may have an air handler or defective thermostat to blame.

When inspecting the outdoor unit, look for any frost or ice which may be forming on the outdoor coil of the unit itself. It may indicate a defective control module, defective defroster timer, or it could be low on refrigerant. Ensure you also check that the airflow to the unit isn’t restricted by grass or weeds. During winter, making sure the system is free from snow and debris is super important!

A faulty compressor valve or refrigerant flow issue could also cause problem of the heat pump blowing out cold air, which once again can be solved by getting in touch and our engineers will sort this for you.

Incorrect Cycling.

If your heat pump is on an off and on cycle, it could be overheating. This would be due to a malfunctioning blower or even a clogged air filter. Cleaning or changing the air filter may solve this problem.

Another cause could likely be the system’s thermostat which could simply need new a battery or be fully replaced. Other issues with the thermostat aren’t as easy to fix and are best left to a professional technician. If you find this to be the issue, contact Heat From Air, we’re always here to help!

If the heat pump is running non-stop, the thermostat may be set too high. For example, in extremely cold temperatures, your heat pump must work a lot harder in order to keep your home warm. Setting the thermostat to a lower temperature to save it some effort may be the solution.

Making Unusual Noises.

Rattling: If you hear this sound coming from your heat pump, it could be an out-of-place register or loose hardware. If the cover panels are not screwed on as tight as they should be, make sure to tighten them. If the noise persists or gets worse, contact us immediately.

Grinding or Squealing: Make sure to turn off your heat pump immediately and call us to schedule a service visit. This could indicate a more serious issue, such as worn-out motor bearings.

Loud hum: This may be caused from poor airflow and the system operating harder than it needs to. Clean those filters!

If you’re unsure on the unusual sound your heat pump is making, don’t hesitate to contact us. Of course, the sooner we’re able to locate your heat pump problems and fix them, the better!
