Air Convenience — Spares & Repair Lookup
Air Convenience: sort your heating & cooling faster
Air Convenience is Climate Cart's parts and repair service — one place to work out what's wrong with a heat pump, air conditioning unit or ventilation system, whatever the brand, and get the right part or advice fast.
What's the problem?
Pick what's happening and we'll tell you the likely cause and what to do next.
Not cooling or heating properly
Likely cause: a blocked filter, low refrigerant charge, a frozen coil, or (on heat pumps) low system flow.
What to do: check and clean the filter first — this alone fixes most "not cooling" calls. Still off after that, it usually needs a qualified engineer to diagnose, since refrigerant work is F-Gas certified only.
Making a noise or vibrating
Likely cause: a loose outdoor unit bracket, worn anti-vibration mounts, or a fan/compressor bearing on its way out.
What to do: check the brackets are tight and the mounts haven't perished — often a same-day fix. Persistent grinding or knocking usually means a part needs replacing.
Leaking or dripping water
Likely cause: a blocked or failed condensate drain — the single most common fault call, especially on older units.
What to do: a blocked drain is often a simple clean-out. A failed pump needs replacing — the Aspen Mini Lime condensate pump is the trade-standard fix.
Remote or controls not working
Likely cause: dead batteries, a worn-out original remote, or (rarer) a receiver/PCB fault.
What to do: new batteries first. If the remote itself has failed, a universal replacement (compatible with all major AC brands, around £20) usually sorts it same day. A PCB fault needs the model-number lookup below.
Musty or bad smell
Likely cause: a dirty coil or a build-up inside the indoor unit — common if it hasn't been serviced in a while.
What to do: a coil clean sorts this in most cases. Persistent or heavy cases may need a professional deep-clean.
Showing an error code
Likely cause: every brand uses its own fault-code system — Daikin, Mitsubishi, LG, Samsung and others all differ.
What to do: check our error code guides on the Advice hub, or email us the code plus your model number and we'll tell you exactly what it means.
Just need a routine service
What keeps a system efficient: a clean filter, a clean coil, and — on heat pumps — a protected primary circuit (magnetic filter plus inhibitor).
What to do: email us your model and we'll confirm exactly what your system needs and the cost.

Full model-number lookup
For anything specific to your exact unit — a PCB, sensor, fan motor or a part not listed above — this is the fastest route:
- Find the model number on your unit's data plate (e.g. "PUZ-WM85VAA", "FTXM25R")
- Email it to us with a photo of the data plate and a description of the fault (or the error code)
- We confirm the exact compatible part, price and lead time — usually same day

Not sure if it's worth repairing?
Read our honest repair-or-replace guidance, or ask — we'll tell you straight if a new unit makes more sense than a £400 PCB.
