Air conditioning not playing ball? Let’s sort it.
Whether it’s blowing warm, dripping, or simply due its annual service — we match you with one vetted, F-Gas certified local engineer. Free to use, no obligation, and never five firms ringing you.

Most faults are cheaper than people fear
A diagnosis visit typically runs £60–120, and many engineers put it toward the repair. The honest exception is refrigerant — see below.
Not cooling properly
Blowing warm, or taking forever to reach temperature. Often a filter, a sensor — or refrigerant that has leaked out.
Water dripping indoors
Usually a blocked condensate drain or a failed pump. Cheap to fix early, messy if ignored.
Won’t switch on
Tripped breaker, failed capacitor or a PCB fault. An engineer can tell which within minutes.
Noisy or rattling
Fan bearings, loose brackets, or debris in the outdoor unit. Rarely serious if caught early.
Annual service due
Most manufacturer warranties require a documented yearly service. Miss it and you can void the cover.
Just moved in

“Topping up the gas” usually means you have a leak
Air conditioning is a sealed circuit — refrigerant isn’t consumed like petrol. If your system is low, it went somewhere, and that almost always means a leak. A cheap regas that ignores this isn’t a repair; it’s a deposit on the next one. The gas escapes through the same hole, you’re back to warm air within months, and you’ve paid twice.
A good engineer finds the leak first — pressure test, electronic detector or UV dye — repairs it, then vacuums and recharges the system. That’s why an honest price for “a regas” is higher than the cheapest adverts: the top-up is the cheap part; finding the leak is what you’re really paying for. If someone offers to gas it up without mentioning leaks at all, treat that as a red flag.
Anyone handling refrigerant in the UK must be F-Gas certified — that’s law, not a nicety. Every engineer we match holds it. Full detail in our repair cost guide, and if you’re troubleshooting first, try why is my air conditioning not cooling?
Worth trying before you call anyone
- Clean or rinse the filters — a surprising share of “broken” units are just clogged.
- Check the outdoor unit isn’t choked with leaves or boxed in.
- Check the breaker at the fuse board, and put fresh batteries in the remote.
That’s where safe DIY ends. Don’t remove casings — components can hold a charge even with the power off — and never touch the refrigerant pipework.
Repair or replace?
A rough rule: if the unit is under ten years old and the repair costs less than about a third of a new system, repair it. Above that, think hard. Systems old enough to run on R22 refrigerant can’t legally be regassed at all, so a refrigerant fault there effectively means replacement — and a modern unit doubles as an efficient winter heater.
