Our fan coil unit service work in the UK is delivered by directly employed, qualified commercial HVAC engineers — never sub-contracted. Every job is scoped properly before we attend, priced as a fixed written quote or clear per-unit rate with no hidden extras, and finished with a same-day service report covering chilled water (CHW) and LTHW flow and return temperatures, coil cleanliness, air volume, motor currents, control valve actuator response and condensate tray operation. We work to BESA SFG20, CIBSE guidance, and manufacturer specification for all major FCU brands including Daikin, Diffusion, Carrier, Trane, Kampmann, Nuaire and Dunham-Bush.
We deliver FCU maintenance for corporate offices, hotels, hospitals, universities, residential blocks and commercial developments across the UK. Whether you have 10 ceiling void chassis units or a 500-unit perimeter casing estate, our engineers carry out systematic planned preventative maintenance (PPM) to maintain indoor comfort, prevent water leaks, reduce noise and keep energy consumption low.
Common issues we resolve during fan coil unit servicing include condensate tray overflow and blocked drain lines, stuck or passing 2-port and 3-port control valves, failed valve actuators, fan motor or bearing wear causing noise, dirty filters and coils restricting airflow, BMS communication faults, and out-of-calibration wall sensors.
