Precision Heat Pump Servicing

Expert Heat Pump Repairs

We have extensive experience resolving common faults such as:

  • Inconsistent heat output or cold radiators
  • Sudden system shutdowns and error codes
  • Excessive ice build-up on the outdoor unit
  • Unusually noisy operation or vibrations
  • Low refrigerant levels and F-Gas leaks
  • Sensor failures and electrical communication issues

Why Regular Heat Pump Servicing Matters

While air source heat pumps are incredibly reliable, they are sophisticated pieces of engineering that benefit from annual professional attention. That’s why we offer regular heat pump system servicing in Gravesend and beyond.

Protect Your Warranty

Most major manufacturers – including Vaillant, Samsung, and Mitsubishi – require an annual service by a certified engineer to keep your warranty valid.

Maximise Efficiency

Over time, debris on the evaporator coils or incorrect flow rates can force your pump to work harder. We optimise your settings to ensure you maintain the highest possible SCoP (Seasonal Coefficient of Performance).

Prevent Winter Breakdowns

A summer or autumn service allows us to catch minor issues before they turn into a mid-winter emergency.

Our Heat Pump Servicing Process

At Heatswap, we don’t believe in “quick look” servicing. Because we are Heat Geek and MCS-accredited specialists, our maintenance process is a deep-level technical audit designed to squeeze every bit of efficiency out of your system.

Performance & Airflow Optimisation

We start with the outdoor unit, performing a deep clean of the evaporator fins to ensure there is zero restriction to airflow. We also check the fan balance and motor to ensure the unit remains as quiet as the day it was installed.

Hydraulic & Fluid Health

We check your system’s water pressure and, more importantly, the concentration levels of your glycol (antifreeze) and corrosion inhibitors. We also remove and clean your magnetic system filter.

F-Gas & Electrical Safety

As F-Gas certified engineers, we carry out a full leak detection check on the refrigerant circuit. We also inspect the electrical terminals for any signs of wear or heat damage and verify that the compressor and sensors are operating within the manufacturer’s specific tolerances.

Handover & Warranty Support

Once finished, we provide a full service report. This acts as your proof of maintenance for manufacturer warranties and government compliance.
