Is Your Air Con Telling You Something?
Recognise the Signs
Most A/C problems give you warning signs. If any of these sound familiar, it's worth getting it checked before the warm weather arrives.
Blowing warm or lukewarm air
The most common sign — refrigerant is low and the system can't cool effectively. Usually a straightforward recharge.
Takes a long time to cool down
Air con used to cool quickly but now takes 10–15 minutes to get comfortable. Often a partial refrigerant loss.
Water dripping inside the car
A blocked condensate drain — water that should exit under the car is collecting in the footwell instead. Easy fix.
Musty or unpleasant smell
Bacteria build-up in the evaporator — very common after winter. An anti-bacterial treatment and new cabin filter usually sorts it.
Rattling or noise when A/C is on
Could be the compressor clutch, a loose component, or debris in the system. Needs investigation before regassing.
It's been over 2–3 years
Even if it feels OK, refrigerant levels will have dropped. A recharge now prevents the system working harder than it needs to.
Not sure if it's the A/C or the pollen filter? That's fine — bring it in and we'll tell you. A musty smell in particular can be either or both. We'll check before recommending anything, and you won't be committed to any work until you've agreed to it.
Recharge or Repair — Which Do You Need?
Two Different Jobs
Most customers who come in with a warm air con just need a recharge — it's quick, affordable, and common. Some systems have an underlying fault. We'll always diagnose first so you're not paying for the wrong thing.
A/C Recharge (Regas)
The routine, most common serviceAir conditioning refrigerant slowly leaks from even healthy systems — it's normal. Over 2–3 years, most cars lose enough refrigerant that cooling performance drops noticeably. A recharge tops up the gas, and your air con works like new.
- Refrigerant recovered, system vacuumed, then recharged to the correct weight
- UV dye added so any future leaks are easy to locate
- Vent temperature measured before and after to confirm the fix
- Typically completed in 1 - 1.5 hours
- R134a (older cars) and R1234yf (2017+ cars) both handled

When there's an underlying problemIf the system has a leak, a faulty compressor, a failed condenser, or an electrical issue, just regassing it won't solve the problem — the gas will escape again. We diagnose the root cause properly before recommending any repair.
- Electronic leak detection and UV dye inspection
- Compressor, condenser, and evaporator checks
- Blower motor and electrical diagnosis
- Cabin filter inspection (often overlooked — it affects airflow)
- Written report of findings before any work is authorised

A/C Sanitiser Treatment
If your air con has a musty or stale smell, an antibacterial sanitiser bomb treats the source — not just the symptom. Done during the recharge, it adds no extra time to your visit.
- Kills bacteria and mould growing inside the A/C system
- Eliminates stale and musty odours at the source
- Administered during the recharge — no extra visit needed
- Worth combining with a pollen filter change if that's also due

We Service A/C Systems in Cars, Vans & Motorhomes
All Vehicle Types Welcome
Cars & SUVs
All makes and models. Both R134a (pre-2017) and R1234yf (newer cars) refrigerant systems handled.
Vans & Motorhomes
We service air conditioning on commercial vans and motorhomes — especially important given the A/C season for leisure vehicles.
Light Commercials
LCVs and light commercial vehicles up to 3.5t — driver comfort matters, especially for tradespeople using their van all day.
R134a or R1234yf?
You don't need to know which refrigerant your car uses — we'll confirm it before any work begins. But here's the difference if you're curious.
R134a
Older systems — cars registered before ~2017
Standard refrigerant
Used in most cars registered before 2017. If you're not sure which yours uses, we'll confirm it before any work begins. We're fully equipped to recover, vacuum, and recharge R134a systems.
R1234yf
Newer systems — most cars from 2017 onwards
Low-GWP refrigerant
Required by law in all new cars from 2017. Significantly more environmentally friendly, but more expensive per kilogram than R134a. If your car was registered from 2017 onwards it most likely uses R1234yf. We stock both and are fully equipped to handle either.
Ready for an ice-cold summer?
Call us or book online — we'll diagnose, recharge, and have you on your way, usually within the hour. No upselling, no pressure, just honest work.
Frequently asked questions
Why is R1234yf more expensive — and what will it actually cost?
R1234yf has a much lower global warming potential than the older R134a and is now required by law in all new cars. Most cars registered from 2017 onwards use it. The trade-off is cost: R1234yf is significantly more expensive per kilogram.
Pricing is a fixed service charge plus a per-gram cost for the refrigerant used. Most cars need 300–500 grams to fully recharge, though this varies by model. At current refrigerant prices, a typical R1234yf recharge costs around £150–£200 inc VAT. Some larger systems need up to 800 grams, which brings the cost higher.
We’ll confirm your refrigerant type and the cost with you before any work begins, so there are no surprises on the bill.
How do I know if I need a recharge or a repair?
Most cars with warm air con just need a recharge, so that’s where we start. When we regas the system, we add UV dye. If the cooling fades again afterwards, book a diagnostic. The dye shows us exactly where the gas is escaping, and we’ll give you an estimate for the repair before any work is done.
How long does an A/C recharge take?
Typically 1 to 1.5 hours for a straightforward recharge. We recover the old refrigerant, vacuum the system, recharge to the exact manufacturer specification, and test the vent temperature to confirm it’s working correctly. If a repair is needed, we’ll advise on timing once we’ve diagnosed the fault.
How often should car air conditioning be serviced?
Every 2–3 years as a general guide, even if the system seems to be working fine. Refrigerant naturally migrates out of the system over time — a small loss is normal. Keeping the charge topped up means the compressor isn’t working harder than it needs to, which extends component life.
My air con smells musty – what causes that?
A musty or stale smell when the A/C runs is usually bacteria or mould growing inside the system, a blocked or overdue pollen filter, or both. We’ll check both when you bring the car in and advise what’s actually causing it before recommending anything.
Do you service motorhome air conditioning?
Yes — we service the cab air conditioning on motorhomes and campervans. This is the driver cab system (the same as a car). Separate roof-mounted habitation air conditioning units are a different system and not something we cover.
Could I just top up the refrigerant myself?
DIY top-up kits are available but we’d caution against them. They don’t recover the old refrigerant before adding new, which degrades system performance over time. They also won’t detect leaks — so you might be topping up a system that will just lose refrigerant again. A proper recharge on professional equipment recovers, vacuums, and recharges correctly, and takes the same amount of time.
