Why Do Heat Pumps Need Servicing?

Air Source Heat Pumps (ASHP) are highly reliable, but they operate outdoors year-round. Over time, the evaporator fins can become blocked by leaves, dust, and debris, forcing the unit to work harder to extract heat from the air. This drastically lowers the system's Coefficient of Performance (COP)—meaning higher electricity bills for you.

Furthermore, testing the concentration of the anti-freeze (glycol) in the system is critical to prevent the external pipework from freezing during winter.

As an MCS Certified business, AB1 Plumbing & Heating Services provides expert, warranty-approved maintenance for air source heat pumps across Llanelli, Swansea, and Carmarthenshire.
