Common Heat Pump Problems and How to Fix Them

Heat pumps are a popular choice for heating and cooling homes and commercial properties because of their energy efficiency and versatility. However, like any mechanical system, heat pumps can experience problems over time if neglected, not maintained or as they age. Here are five common heat pump problems and how to fix them.


Lack of Heat

As we leave summer behind, the need to heat our properties grows. If your heat pump isn’t providing enough heat, check the air filter to make sure it’s clean. A dirty filter can restrict airflow and reduce output. Another possible cause of a lack of heat is a faulty thermostat. Check the thermostat to make sure it’s set to the desired temperature and is functioning properly. If the filter and thermostat are both in good condition, it’s possible that the heat pump’s refrigerant level is low. In this case, contact Fonko to arrange for a professional heat pump technician to take a look.


Noisy Unit

No one likes listening to a knocking or loud humming when they are relaxing at home or working. If your heat pump is making loud or unusual noises, it’s likely due to a problem with the fan or compressor. A fan that is loose or damaged can create a grinding or rattling noise, while a faulty compressor can make a buzzing or humming sound. If you hear any of these noises, turn off the heat pump and call us for support.


Frozen Coils

Frozen coils are a common problem in heat pumps, especially during the coming winter months in New Zealand. If you notice ice buildup on your heat pump’s coils, turn off the system and let the ice melt naturally. Once the ice has melted, check the air filter to make sure it’s clean – it may need replacing. If the coils continue to freeze, it may be due to a refrigerant leak, which requires professional attention.


Uneven Functionality

If your ducted heat pump is providing uneven heating or cooling, it’s possible that there’s a problem with the ductwork. Inspect the ducts for leaks, cracks, or other damage, and seal any gaps with duct tape or mastic sealant. Another possible cause of uneven heating or cooling is a dirty or blocked air handler. Check the air handler and clean or replace the filter if necessary.


Unit Won’t Turn On

If your heat pump won’t power up, the first step is to check the thermostat to make sure it’s properly set and functioning. If the thermostat is working properly, check the power supply to the heat pump to make sure it’s not tripped. If this isn’t the issue, it’s possible that there’s a problem with the heat pump’s control board or compressor. To get your heat pump working like new, ask Fonko.
