Are you relying on an air source heat pump to keep your home warm and energy-efficient? These eco-friendly systems are a smart alternative to traditional boilers, but like any heating system, they need regular care to perform at their best. Whether you’ve just installed one through Reliant Energy Solutions or have had one for years, maintaining your system is the key to lower bills and longer lifespan.
With UK energy prices still high in 2025 and households focusing more than ever on sustainability, these top 8 air source heat pump maintenance tips will help you maximise performance, cut costs, and stay warm year-round.
1. Clean and Clear the Outdoor Unit Regularly
Your heat pump’s outdoor unit must breathe freely. Clear away leaves, dirt, grass clippings, snow, or debris that can block airflow and reduce efficiency. Ideally, keep at least 30cm of space around the unit.
Tip: Check every two weeks, especially during autumn and winter.
2. Inspect Air Filters Monthly
Dirty air filters restrict airflow and make your pump work harder. Check your filters at least once a month. Clean or replace them depending on the manufacturer’s guidelines.
Pro Tip: Set a reminder each month—clean filters improve indoor air quality and reduce energy use.
3. Schedule a Professional Service Annually
Even if everything looks fine, your system should be serviced by a certified engineer every year. A professional will check for refrigerant leaks, test efficiency, clean internal components, and ensure everything is running safely.

4. Check Thermostat Settings
Smart thermostats and heat pump-compatible controllers allow better energy management. Ensure your thermostat is properly calibrated and set to energy-efficient temperatures.
Energy Saving Range: 18–21°C is ideal for most UK homes.
5. Monitor Energy Consumption Trends
Keep an eye on your energy bills. A sudden spike in usage might signal a fault or drop in performance. Smart meters or home energy management systems can provide real-time data.
Did You Know? Monitoring patterns can help spot issues early and avoid costly repairs.
6. Defrost Mode Awareness
Air source heat pumps naturally go into defrost mode during freezing conditions. However, if your unit is constantly freezing or doesn’t defrost properly, it could be a sign of a problem.
Solution: Make sure gutters above the unit don’t leak water onto it and keep airflow unobstructed.
7. Insulate Pipes and Ducts
To prevent heat loss and boost efficiency, ensure all refrigerant lines and ducts (especially those running outdoors or in unheated spaces) are well-insulated.
Extra Tip: Upgrade insulation during your next home energy audit.
8. Keep Software and Firmware Updated
Many modern heat pumps have smart controllers or apps. Always keep these updated to benefit from the latest efficiency algorithms and error-detection tools.
Bonus: Manufacturers often release updates that improve functionality and efficiency.
