To make sure your air source heat pump continues to perform efficiently and reliably, it’s essential to have it serviced regularly by a qualified engineer.
At Went’s Heating Services Ltd, we specialise in monobloc air source heat pump servicing across South Shropshire and parts of Herefordshire & Powys, helping homeowners keep their systems running smoothly all year round.
Do Air Source Heat Pumps Need Servicing?
Yes — just like a gas or LPG boiler, an air source heat pump should be serviced annually.
Regular maintenance helps:
-
Keep the system performing efficiently
-
Prevent unnecessary breakdowns
-
Prolong the lifespan of the unit
-
Keep the manufacturer’s warranty valid
Most manufacturers recommend an annual service to maintain warranty coverage and ensure peak performance. A well-maintained heat pump can last 15 years or more if properly cared for.
How Often Should an Air Source Heat Pump Be Serviced?
In most cases, an annual service is sufficient, but systems in heavy use or exposed to debris (e.g., rural or coastal locations) may benefit from a mid-year check.
Always follow your manufacturer’s warranty requirements, as some specify servicing intervals or approved engineers.
Your heat pump service should always be carried out by a competent engineer with heat pump training — even though monobloc systems are sealed and do not require an F-Gas qualification, they still need careful maintenance to ensure efficiency and safety.
What’s Included in a Heat Pump Service?
A typical air source heat pump service from Went’s Heating Services Ltd includes:
-
Full visual inspection of the unit and surrounding area
-
Temperature and performance checks
-
System diagnostics and operational testing
-
Cleaning of filters, coils, and fan blades to remove debris
-
Inspection of electrical connections and controls
-
Check for water leaks or air in the system
-
Advice on optimal system settings for efficiency and comfort
We also make sure your system is operating quietly and that airflow isn’t restricted by leaves, dust, or overgrown plants.
How to Help Maintain Your Air Source Heat Pump
There are simple steps you can take between services to keep your heat pump working efficiently:
1. Keep the Area Clear
Ensure there’s at least 1.5 metres of clear space around the outdoor unit. Trim back any plants or bushes and remove debris such as leaves or twigs.
2. Monitor Your System Pressure
Your system should maintain steady water pressure (usually around 1 bar). If it drops, it may affect heating performance. Check the gauge occasionally and contact us if you’re unsure.
3. Clean the Unit Gently
Wipe the exterior casing and gently brush away dust or dirt from the air intake and grille. Avoid using a hose or pressure washer.
4. Check Electrical Wiring
If you notice damage to cables, insulation, or isolator switches, turn off the unit and contact a professional engineer immediately.
5. Listen for Changes
If your heat pump sounds louder than normal or isn’t heating efficiently, it may need servicing sooner.
