Air conditioning systems should be serviced annually — filters and coils cleaned, refrigerant levels checked, electrical connections inspected, and condensate drainage verified. This is best practice and standard manufacturer guidance; it also aligns with legal F-Gas obligations. Under the Fluorinated Greenhouse Gases Regulations 2015 (SI 2015/310), retained in UK law post-Brexit, refrigerant leak checks are mandatory at intervals determined by system charge size — annually for most residential and small commercial units. For commercial buildings with air conditioning above a combined 12kW effective rated output, a TM44 inspection is mandatory every five years under the Energy Performance of Buildings Regulations, carried out by an accredited energy assessor. Mainteniq's F-Gas certification REF1024168 (Refcom/BESA Group, valid to March 2029) covers all refrigerant work across London and 120 miles.
