Air source heat pump servicing: A complete guide

Do air source heat pumps need servicing?

To make sure that you can get the most out of your air source heat pump, you should look to get it serviced each year.

This will not only mean that your heat pump is kept in good shape, but an up to date service history will keep your warranty valid. So, if something should go wrong, you may be able to get it repaired or replaced without extra cost.

A yearly service will also help you prolong the life of your heat pump. One of the biggest benefits of a heat pump is that it can last around 15 years or more if properly maintained.

In some cases, you may also need a regular service history to ensure you remain eligible for any Renewable Heat Incentive grant you may have received from the government.

How often do air source heat pumps need servicing?

Just like a regular boiler, you should try and follow the conditions of your heat pump warranty or guarantee. In most cases, this means that you’ll need to get your heat pump serviced once a year.

You should keep in mind that this service should only be carried out by a competent person who has received training in heat pump technology.

What’s included in an air source heat pump service?

When you have an air source heat pump service, this will usually include:

• A full visual check
• Temperature checks
• System checks (visual and diagnostic)
• All heating pipework checked for leaks
• Cleaning of internal components
• Electrical circuits test
• Professional advice on system set-up and product use

How much does it cost to service an air source heat pump?

Usually, a heat pump service can cost anything from £150 to £300, which can vary depending on the type of heat pump you have. The average cost is around £200 for a mid-range heat pump.

How can I help to maintain an air source heat pump?

Aside from making sure that you keep on top of your yearly service, there are a few ways that you can help maintain your air source heat pump. Let's take a closer look...

1. Remove any obstructions

One of the best ways you can make sure that your heat pump has enough airflow is to keep any trees, bushes, and other obstructions at least 5ft away from it. If any branches are blocking the heat pump, you should trim or remove them to keep it clear.

2. Monitor your water pressure

Just like a traditional gas boiler, your air source heat pump is part of a heating system that relies on a certain amount of water pressure to effectively heat your home. With an air source heat pump, your system’s water pressure should be set to 1 bar, so checking your water pressure and making sure it’s at the right level will help keep things running as they should.

3. Clean the unit

Another great way of keeping everything working properly is to regularly clean your unit with a soft brush. This will help remove any dirt or debris that can build up and block any of the working parts.

If you’re unsure about how to clean your unit, ask your heating engineer or check your heat pump manual for advice. To keep things simple, just brush down the outside of the unit with a soft brush and make sure nothing is blocking the air flow.

4. Check electrical wiring

Having your wiring checked regularly for any damage or signs of wear is all part of your service. However, if you notice anything before your service date, make sure you call a qualified engineer.

5. Check for wear

While your system may not need significant repairs regularly, checking for general wear and tear and getting issues fixed as soon as you spot them will help you prolong the life of your heat pump.

If you’re not sure how you can check your systems manual or ask your service engineer when they next come to visit.

Keep your air source heat pump running smoothly 

Just like with a boiler, it’s important to service your heat pump once a year to make sure it’s operating as efficiently as possible throughout the year. This will help stop any preventable breakdowns or problems that could crop up without regular servicing.

Don't wait until it's too late—schedule your air source heat pump service today and enjoy peace of mind knowing your system is ready to perform when you need it most.
