What We Service
Regular servicing is essential to keep your heating and cooling systems running smoothly and efficiently. It helps reduce energy consumption, lowering your bills while extending the lifespan of your system and protecting your investment. With routine maintenance, your system will perform at its best year-round, minimising the risk of unexpected breakdowns and ensuring reliable operation when you need it most.
Heat Pumps
We provide comprehensive maintenance for both air-source and ground-source heat pumps. Our experts ensure that your system is free from blockages, operating at the correct pressures, and maximising energy efficiency.
Underfloor Heating
Regular servicing ensures even heat distribution and prevents common issues like airlocks or system imbalances. We also check for proper thermostat operation and inspect components for wear and tear.
Air Conditioning
Stay cool and efficient with professional servicing for your air conditioning units. We clean filters, check refrigerant levels, and ensure the system operates efficiently and quietly.
MVHR Systems
Ensure healthy indoor air quality with routine MVHR maintenance. We clean filters, inspect ductwork, and test the heat recovery function to optimise your system’s performance.
