Air Source Heat Pump Servicing & Repairs Across Dorset & Surrounding Areas

Specialist Heat Pump Servicing, Fault Finding & Repairs

ThermoLoco provides professional air source heat pump servicing, fault finding and repairs across

Dorset and surrounding parts of Somerset, Wiltshire, Hampshire and East Devon.

Based near Dorchester, we travel throughout the region to service and repair heat pump systems,

whether they were installed by us or by another installer.

We work on systems from leading manufacturers including

Daikin, Mitsubishi Electric (Ecodan), Vaillant and LG.

ThermoLoco is MCS certified and F-Gas qualified, giving us the expertise to work on both

the heating and refrigerant sides of air source heat pump systems.

Heat Pump Servicing

Regular servicing helps keep your air source heat pump operating efficiently and can identify potential problems before they develop into costly faults.

A heat pump service can include checks on system pressures, temperatures, flow rates, filters, controls, electrical components, refrigerant-side operation and the overall performance of the system.

We can service heat pumps installed by ThermoLoco as well as systems installed by other companies.

Heat Pump Repairs & Fault Finding

If your heat pump is not heating properly, producing hot water correctly, showing a fault code or repeatedly stopping and starting, we can investigate the problem.

Heat pump faults can be caused by issues on either the heating system or refrigerant side, including poor flow rates, pumps, valves, sensors, controls, wiring or refrigerant-related problems.

Our experience with both heating systems and air conditioning/refrigeration allows us to diagnose the whole system rather than looking at only one side of the installation.
