London Air Conditioning & Heating Maintenance Contracts
Professional maintenance for all heating, ventilation, air conditioning, and commercial refrigeration systems. F-Gas certified, London and 120-mile radius.
Air conditioning and heating maintenance covers the planned servicing of all mechanical systems controlling temperature, ventilation, and air quality in a building. In London properties this typically means fan coil units (FCU), heat interface units (HIU), central interface units (CIU), mechanical ventilation with heat recovery (MVHR), boilers, and split or multi-split air conditioning. Annual servicing is best practice for residential systems; commercial AC above 12kW requires an energy inspection every five years under the Energy Performance of Buildings Regulations. F-Gas legislation requires annual leak checks on refrigerant-based systems. Mainteniq provides planned maintenance contracts covering all of these, for landlords, property managers, and facilities teams across London and a 120-mile radius.
