Heat Pump Servicing & Repair in Portsmouth, Hampshire

If your heat pump is not providing the warmth you expect, making unusual noises, or displaying error codes, it could be time for a professional service or repair. Homeowners and light commercial customers across Portsmouth and Hampshire rely on GEO M&E Ltd to diagnose and resolve heat pump faults quickly and efficiently, restoring comfort and system reliability.

Common Heat Pump Problems We Fix

Heat pumps are complex systems that can develop a range of issues affecting performance and safety. Some of the most frequent problems our engineers encounter include:

  • Poor heating output or uneven warmth throughout the property

  • Defrost cycle issues causing icing on the outdoor unit

  • Strange or loud noises from compressors, fans, or pumps

  • Electrical faults such as tripping breakers or blown fuses

  • Low system pressure or flow temperature irregularities

  • Error codes or warnings on the controller or thermostat

  • Leaks in refrigerant lines or condensate drainage

  • Controller or thermostat malfunctions affecting system control

Recognising these symptoms early and arranging expert servicing can prevent more costly breakdowns and maintain system efficiency.

What to Expect from Our Heat Pump Servicing & Repair Process

GEO M&E Ltd follows a thorough, step-by-step diagnostic and servicing procedure to identify faults and optimise your heat pump’s performance.

  1. Initial Visual and Safety Checks: Our engineer inspects the outdoor and indoor units for visible signs of wear, damage, or blockages, while ensuring electrical isolation and safety protocols are adhered to.

  2. System Pressure and Flow Temperature Assessment: We measure refrigerant pressures and flow temperatures to detect leaks or inefficiencies within the system.

  3. Filter and Strainer Examination: Cleaning or replacing filters and strainers to maintain good water or air flow and prevent damage to pumps and valves.

  4. Circulation, Pumps, and Valve Testing: Confirming that circulation pumps and valves operate correctly to maintain steady heat distribution.

  5. Electrical Safety and Performance Testing: Comprehensive checks of wiring, connections, and electrical components to detect faults or risks that could cause tripping or damage. Finally, we perform performance tests to confirm the system meets manufacturer specifications.

A typical annual service includes cleaning the outdoor unit, checking condensate drains, assessing inhibitor levels and water quality in wet systems, and verifying antifreeze concentration where applicable. This attention to detail extends the life of your heat pump and maintains warranty compliance.

Before You Call: Safe Homeowner Checks

Before contacting a professional, there are some safe checks you can perform to help identify obvious issues and prepare for the engineer’s visit. Please follow these precautions carefully, avoiding any actions that require technical skills or risk electric shock.

  • Clear Airflow Around Outdoor Unit: Ensure there is no debris, leaves, or obstructions blocking airflow to the unit. Good ventilation is essential for proper operation.

  • Check Heat Pump Settings: Confirm the thermostat or controller is set to the desired temperature and mode (heating or cooling). Sometimes settings can be inadvertently changed.

  • Verify Isolation Switch Position: Make sure the system’s electrical isolation switch is turned on. If unsure, do not attempt to operate electrical components yourself.

If you notice leaks, persistent error codes, or the system continues to perform poorly after these checks, contact GEO M&E Ltd for expert assessment. Never attempt to open or repair electrical or refrigerant components yourself.

Heat Pump Types and System Options

Air Source Heat Pumps

The most common in Portsmouth and Hampshire properties, air source heat pumps extract heat from outside air. Regular servicing ensures the outdoor unit remains clean and free from icing, which can affect efficiency.

Ground Source Heat Pumps

These use underground loops to gather heat and typically require checks on fluid levels, antifreeze concentration, and pipework integrity during servicing. GEO M&E Ltd has experience maintaining both air and ground source systems.

Wet vs. Dry Systems

Wet systems use water to transfer heat through radiators or underfloor heating, needing inhibitor checks and water quality tests. Dry systems rely on air distribution and require filter cleaning and fan maintenance.

GEO M&E Ltd can service all types and brands of heat pumps, including Mitsubishi, Daikin, NIBE, and Samsung units.

Frequently Asked Questions

How often should I have my heat pump serviced?

We recommend an annual service to maintain efficiency, detect faults early, and comply with manufacturer warranty conditions. Some systems in coastal areas like Portsmouth may benefit from more frequent checks due to salt air exposure.

What do strange noises from my heat pump mean?

Noises can indicate issues such as worn fan bearings, pump faults, or refrigerant problems. Early diagnosis helps prevent breakdowns and costly repairs.

Do heat pumps work well in coastal climates like Portsmouth?

Yes. Heat pumps are designed to operate efficiently in a range of climates, including coastal areas. Regular servicing helps protect units from salt corrosion and airflow blockages caused by coastal debris.

Can servicing protect my heat pump warranty?

Most manufacturers require annual servicing by certified engineers to maintain warranty coverage. GEO M&E Ltd provides documentation of all work carried out to support your warranty claims.

Why is my heat pump freezing up during winter?

Freezing or icing on the outdoor unit usually indicates defrost cycle issues or airflow restrictions. Our engineers will diagnose and resolve these problems during servicing.
