Fault diagnosis and repair for air conditioning units that are not cooling, heating or functioning correctly. Compare up to 3 free quotes — no obligation.
Air conditioning faults range from simple fixes (blocked filters, tripped electrics) to complex refrigerant or PCB issues. An F-Gas certified engineer can diagnose the fault correctly first time — avoiding the wasted call-out costs that come from unqualified diagnosis.
Common faults include refrigerant leaks, sensor failures, compressor issues and control board faults. Getting a diagnosis call-out from a qualified engineer is the essential first step before any repair cost is committed.
Typical cost: call-out and diagnosis £80–£150. Minor repairs (sensor, filter, drain) £50–£150 plus call-out. Major repairs (compressor, PCB) £200–£600+.

“Needed air conditioning across 3 rooms in our office. Found a local installer through the site who quoted the best price for a multi-split system. Installed within the week and running perfectly ever since.”
“Booked an annual AC service through the site. Engineer arrived on time, checked the refrigerant levels, cleaned the filters and had everything running efficiently again. Fair price and really straightforward.”
