If you’ve chosen to install an air source heat pump, you’ve already made a smart move toward energy efficiency, lower bills, and a smaller carbon footprint. But just like any well-used piece of equipment, a bit of regular care can go a long way in keeping it running smoothly for years to come.
Here are our top maintenance tips to help you maximise performance and boost the longevity of your air source heat pump.
1. Keep the Outdoor Unit Clear
Your heat pump works by absorbing heat from the air outside, which means the outdoor unit needs good airflow to operate efficiently. Check it regularly to make sure it’s free from leaves, dirt, grass clippings or snow. We recommend keeping a clear space of at least half a metre around the unit.
Also, trim back any shrubs or plants that may be getting too close. This helps prevent clogging and makes the system work less hard to do its job – which means lower energy bills for you.
2. Clean or Replace Filters
One of the simplest things you can do to maintain your system is to clean or replace the filters every 1 to 3 months, depending on usage and the type of filter your system uses. Dirty filters restrict airflow, reduce efficiency and can put unnecessary strain on the unit.
If you’re not sure how to check or change your filters, just give us a ring. We’re happy to walk you through it or come out and do it for you.
3. Check for Ice or Frost Buildup
In colder months, it’s normal for a bit of frost to build up on the coils. However, your heat pump should automatically defrost when needed. If you notice thick ice forming or the system isn’t defrosting properly, it might indicate a problem.
Blocked airflow, dirty coils or low refrigerant levels can all cause frost issues. Don’t ignore this – give our team a call so we can get it sorted quickly before it leads to bigger problems.
4. Keep an Eye on Your Energy Bills
A sudden spike in your energy use could be a red flag. While energy prices do fluctuate, a noticeable change without explanation could mean your heat pump isn’t running as efficiently as it should. It might be working harder than normal due to a blockage, fault or other issue.
Regular servicing can catch these issues early and help keep everything running at peak performance.
5. Listen for Unusual Noises
Your heat pump should run fairly quietly. If you start to hear rattling, buzzing or grinding sounds, don’t ignore them. Unusual noises could be a sign of loose parts, debris caught in the fan or motor issues.
Catching these early can prevent more costly repairs down the line – and save you a lot of hassle.
6. Schedule an Annual Service
We can’t stress this one enough. Just like a car needs a yearly MOT, your heat pump needs regular servicing by a qualified technician. An annual check-up includes inspecting components, checking refrigerant levels, cleaning coils and making sure everything is running safely and efficiently.
Our friendly Green Energy Homes team is fully trained to carry out maintenance that not only keeps your system in top shape but also helps extend its lifespan. And because we understand the system inside and out, we know exactly what to look for.
7. Don’t DIY Repairs
We’re all for a bit of DIY, but when it comes to heat pump repairs, it’s best left to the professionals. Trying to fix things yourself can void your warranty and potentially make things worse.
If something doesn’t seem right, give us a call. We’d rather catch a small issue early than wait until it becomes a major headache for you.
8. Use Smart Controls for Efficiency
If your heat pump came with smart thermostats or controls, learn how to use them to your advantage. Setting schedules, adjusting temperatures by room and avoiding unnecessary heating can all improve performance and save money.
Need help setting up your controls? Our team is happy to guide you through it, whether we installed your system or not.
9. Watch Out for Poor Drainage
During operation, your heat pump may release some condensation. This should drain away smoothly. If you notice pooling water or damp areas around the unit, there could be a blocked or damaged drain.
Proper drainage helps avoid damage to the system and surrounding areas, especially during colder months when water could freeze.
