A properly serviced heat pump maintains its designed Coefficient of Performance (COP), uses less electricity, and lasts significantly longer than a neglected system. This service is for anyone with an installed heat pump — whether it was fitted last year or a decade ago. Regular servicing is especially important if your system heats your home and provides hot water, as performance degradation is often gradual and goes unnoticed until energy bills spike or the system fails entirely. During a service visit, we inspect the full system: outdoor unit condition, refrigerant pressures, electrical connections, flow rates, controller settings, filters, and the condition of emitters such as radiators or underfloor heating circuits. We clean components, tighten connections, and adjust settings where needed. Most manufacturers require annual servicing to maintain warranty cover. Skipping services can void your warranty, leaving you exposed to the full cost of major component replacements like compressors, which can exceed £2,000. ## What Happens If You Wait? A heat pump that has not been serviced for 12 months or more may already be running 10–20% below its designed efficiency. You will not see an error code. You will not hear a strange noise. You will simply pay more on your electricity bill every quarter. Dirty evaporator coils reduce airflow across the heat exchanger, forcing the compressor to work harder and longer to deliver the same heat output. This accelerates wear on the most expensive component in your system. Electrical connections loosen over time due to thermal cycling. A loose connection creates resistance, generates heat, and can eventually cause a PCB failure or trip your consumer unit. This is entirely preventable with annual inspection. Without servicing, minor issues such as slightly low refrigerant charge, a partially blocked filter, or an incorrect defrost setting remain undetected. Each one reduces performance individually. Together, they can cut system efficiency by 30% or more. ## How We Work 1 ### Pre-Visit Preparation We review your system type and service history before arrival so we bring the correct tools and filters. 2 ### Visual & Physical Inspection Full external and internal inspection of the outdoor unit, pipework, insulation, electrical connections, and indoor components. 3 ### Performance Testing We measure refrigerant pressures, flow temperatures, delta T across the system, and compressor current draw to verify operating parameters. 4 ### Cleaning & Adjustment Evaporator coils cleaned, filters replaced, electrical connections tightened, and controller settings optimised for current conditions. 5 ### Service Report & Recommendations You receive a written report detailing our findings, any adjustments made, and recommendations for future attention. This supports your warranty records. ## Why It Matters ### Maintain Peak Efficiency A serviced heat pump runs at its designed COP — meaning lower electricity bills and consistent heating output. ### Prevent Costly Breakdowns Catching minor issues early prevents them developing into major failures that require expensive repairs. ### Protect Your Warranty Most manufacturers require annual servicing by a qualified engineer. We provide the documentation to prove compliance. ### Extend System Lifespan Well-maintained heat pumps routinely exceed 20 years of service life. Neglected systems often fail within 8–12 years. ### Improved Comfort Correctly calibrated settings mean your home reaches target temperature faster and maintains it more consistently. ### Safety Assurance Electrical and refrigerant checks ensure your system is operating safely within all regulatory parameters. ## Technical Detail & Expertise A comprehensive heat pump service goes beyond a simple visual check. We verify the refrigerant charge by measuring suction and discharge pressures against manufacturer specifications for the current ambient temperature. Deviations indicate a potential leak or incorrect charge from the original installation. We check the condition of the evaporator and condenser coils. Outdoor evaporator coils accumulate dirt, leaves, and debris which restrict airflow and reduce heat transfer efficiency. Indoor condensers in split systems can also collect dust, particularly in properties with pets or high-traffic areas. Electrical testing includes verifying compressor winding resistance, capacitor values, contactor condition, and the integrity of all wiring connections. We also check the earth continuity and insulation resistance of the installation to ensure ongoing electrical safety. Controller and thermostat settings are reviewed to ensure weather compensation curves are correctly configured for your property and emitter type. Many systems we service have never had their weather compensation properly set up, meaning they run at unnecessarily high flow temperatures — wasting energy and reducing the COP. For systems with a hot water cylinder, we check the immersion heater function, the heat pump's DHW priority settings, and the legionella protection cycle. Incorrect settings here often result in the immersion heater running unnecessarily, significantly increasing electricity costs. We service all major brands including Mitsubishi Ecodan, Daikin Altherma, Samsung EHS, Vaillant Arotherm, Grant Aerona, Panasonic Aquarea, and Nibe. Each brand has specific service requirements and diagnostic interfaces, and we carry the appropriate tools for each. ### Related Services - [Heat Pump Repair](/services/heat-pump-repair) - [Annual Maintenance Contracts](/services/annual-maintenance-contracts) - [Heat Pump Health Checks](/services/health-checks) - [Commissioning & Optimisation](/services/commissioning-optimisation) - [← Back to Homepage](/) ### Service Areas - [Basingstoke](/areas/basingstoke) - [Hampshire](/areas/hampshire) - [Reading](/areas/reading) - [Guildford](/areas/guildford) ## Frequently Asked Questions ### How often should a heat pump be serviced? ### How much does a heat pump service cost? ### How long does a service visit take? ### Will servicing void my warranty? ### Do you offer annual maintenance contracts? ### Can you service a heat pump installed by another company? ### What happens if you find a fault during a service? ### Do I need to do anything to prepare for a service visit? ### What areas do you cover for heat pump servicing? ### Is a service necessary if my heat pump seems to be working fine? ## Protect Your Investment With Professional Servicing Annual maintenance keeps your heat pump efficient, reliable, and warranty-compliant.
