FAQs
Domestic heat pumps work on thermodynamic principles, using the refrigeration cycle to move heat rather than generate it. By compressing and expanding refrigerant, the system efficiently extracts heat from the air or ground—even in low outdoor temperatures—and transfers it indoors. Like any mechanical system, regular checks are important to keep systems running efficiently and extend the unit’s lifespan. Here's some frequently asked questions when it comes to maintaining heat pump systems.
How often do I need to book a heat-pump service?
Plan for a qualified engineer to visit at least once a year; heavy, year-round use may justify a mid-season check. Regular servicing keeps the warranty valid and keeps efficiency high.
What tasks are covered during a routine service visit?
The engineer checks system performance, cleans the evaporator and condenser coils, inspects electrical connections, tests safety controls, confirms refrigerant charge, flushes the condensate pump, and records the results in a service report. Filters are cleaned or replaced and the outdoor unit is cleared of debris.
Why do I need regular maintenance if the unit seems to run well?
Preventive maintenance lowers energy use, avoids costly emergency call-outs, improves indoor air quality, and extends equipment life. Skipping service can increase running costs and shorten lifespan.
Can I carry out any maintenance myself?
You can vacuum or rinse the indoor filters every one to three months, keep shrubs and leaves at least 30 cm from the outdoor unit, and check that air vents stay clear. Leave electrical or refrigerant work to a certified professional.
Do I have legal duties under the F-gas rules?
Domestic systems usually fall below the 5 t CO2e threshold for mandatory leak checks, yet you still need to arrange repairs quickly if a leak is suspected and keep basic service records. The 2024 EU F-gas revision phases out high-GWP refrigerants, so older units may need lower-GWP refills from 2026.
Will maintenance lower my energy bills?
Yes. A well-tuned heat pump can use 10 %–25 % less energy than a neglected one, which keeps winter bills down and reduces carbon impact.
What warning signs tell me to call sooner?
Book a visit if you notice louder operation, reduced airflow, persistent ice on the outdoor coil, unusual smells, or an unexpected rise in electricity use. Early intervention prevents bigger faults.
How long does a domestic service visit take?
Most visits finish within one to two hours, depending on access and system size. Complex issues may add time, but routine checks are quick and non-invasive.
What happens if I skip annual servicing?
Efficiency drops, small leaks go unnoticed, mould can form on damp coils, and warranty cover can lapse. In many cases repairs cost more than years of scheduled maintenance.
Do you offer service plans and what are the benefits?
Our maintenance plans schedule visits automatically, provide priority repair slots, and spread costs with a fixed monthly fee. Plans help you budget and keep the system in peak condition year after year.
