Air to water heat pumps are energy-efficient systems that can provide cost-effective heating to your home. These heat pumps absorb heat from the outside air and use it to heat your home's water supply. Nevertheless, even the most reliable systems can encounter problems over time. Understanding these issues and knowing how to address them can save you stress and discomfort. Let's explore some common issues with air to water heat pumps and their potential fixes.

Disclaimer: Safety first! While it's beneficial to understand common problems, remember that solving complex issues should be left to experts. High-voltage appliances can be dangerous if mishandled. The solutions presented here are user-friendly, however, if a problem persists, promptly contact a professional HVAC technician.

1. Heat Pump Not Running

If your heat pump isn’t working at all, there could be a multitude of reasons behind this, such as a malfunctioning thermostat, a blown fuse, or a tripped circuit breaker.


Inspect the thermostat to ensure it is set correctly and functioning. Check the circuit breaker and fuses. If either is tripped or blown, try resetting it. If simple troubleshooting steps don’t resolve the problem, it's time to call in an HVAC professional.

2. Insufficient Heating

An inadequately heated water supply may be due to low refrigerant, a malfunctioning compressor, incorrect thermostat settings, or a heat pump that is incorrectly sized for your home.


Check the thermostat settings first. If that's in order, it's preferable to get an HVAC technician on board as diagnosing and addressing issues with refrigerant levels, compressors, or incorrect sizing needs professional expertise.

3. Noisy Unit

Some noise from your heat pump is normal. However, if you observe unusual sounds, such as grinding, gurgling, or squealing, these could indicate mechanical issues.


Unusual noises often stem from component issues inside the heat pump, such as the compressor or fans. Get a professional involved as soon as you notice these noises to prevent further damage.

4. Frequent Cycling

If your heat pump repeatedly turns off and on, this can indicate a problem. The causes can range from dirty coils or air filters, a malfunctioning thermostat to more severe issues like refrigerant leakage.


You could start by cleaning or replacing the air filter. However, dealing with dirty coils or refrigerant leakage should be left to a professional as these can be complex and potentially hazardous tasks.

5. Water Leaks

Water leaks can occur due to numerous issues such as broken seals, loose connections, or a rusted storage tank.


In case of small leaks, you could try tightening the connections. However, if the leak persists or you notice a rusted storage tank, you should call a professional for a thorough inspection and repair.


Understanding common problems with your air to water heat pump can save you time and inconvenience, helping maintain the system's longevity and efficiency. Remember, consistently scheduling professional maintenance can prevent many of these issues in the first place.

However, if complex issues arise or persist even after troubleshooting, do not hesitate to enlist the help of an HVAC professional. Safety and efficiency should always be the highest priorities when dealing with high-voltage home appliances.
