Troubleshooting Common Heat Pump Problems: An Easy DIY Guide

Are you a homeowner in Christchurch, New Zealand, struggling with heat pump problems? If so, you're not alone. Heat pumps are an incredibly efficient and eco-friendly heating solution, but like any appliance, they can occasionally run into issues. In this blog post, we'll provide an easy DIY guide to troubleshooting the most common heat pump problems.

Before we dive in, it's important to remember that while some issues can be resolved with a bit of DIY know-how, others may require the expertise of a professional. If you're unsure, don't hesitate to reach out to the team at for expert advice and service.

1. Heat Pump Not Heating or Cooling Properly: This is a common problem that could be due to a variety of reasons. Check your thermostat settings first but remember heat rises! So it is hotter at ceiling height where the heat pump & its temperature sensor is usually located than it is at floor level this can vary by a few degres depending on location, try turning the temperature up a few degrees If that's not the issue, it could be due to a dirty air filter restricting airflow. Regularly cleaning your air filters can prevent this issue.

2. Heat Pump is Noisy: Heat pumps should operate relatively quietly. If you notice unusual noises, it could be due to loose parts, a worn fan motor, or issues with the compressor. Some noises can be resolved by tightening loose parts, but others may require professional attention.

3. Heat Pump is Leaking Water: If you notice water pooling around your heat pump, it could be due to a blocked drain pipe, a frozen coil, or a broken condensate pump. Some of these issues can be resolved by cleaning the affected parts, but others will need professional repair.

4. Heat Pump Won’t Turn On: This could be due to a tripped circuit breaker, a blown fuse, or issues with your thermostat. Check your electrical switchboard to make sure the circuit breaker is on and thermostat settings first. If the problem persists, it's time to call in the professionals.

5. High Energy Bills: If you notice a sudden spike in your energy bills, it could indicate that your heat pump is not operating efficiently. This could be due to dirty coils & filters, a malfunctioning thermostat, or low refrigerant levels. Regular maintenance can help prevent these issues.

6. Heat Pump is not responding to remote: This could be due to the batteries being flat in your remote, if you notice the screen on the remote is hard to see it usually means the batteries are almost flat and need to be replaced
