Air Con
Not Blowing
Cold?

Air conditioning gradually loses refrigerant charge over time — most cars lose around 10% per year. When it's low enough, the compressor cuts out and you get warm air. PAD comes to you, checks pressure first, tops up if needed.

Two ways
to book.

Price depends on your refrigerant type — R134a (older cars, pre-2017) costs less than R1234yf (newer cars). Already having a PAD diagnostic or battery test? Add the air con top-up to the same visit and save further.

Standalone Top-Up from £50

Dedicated Visit

A visit purely for the air con. PAD comes to your home, workplace, or wherever the car is parked. Mileage included within the standard service area across South Wales.

  • R134a system — £50
  • R1234yf system — £65
  • Low-side pressure check before anything is added
  • Top-up to correct level, post-fill performance confirmation

Combined Visit

Already booking an EV battery check, 12V load test, or diagnostic? Add the air con top-up to the same visit. No second callout, no additional travel. Everything done in one stop.

  • R134a system — £35
  • R1234yf system — £50
  • Same checks and top-up as standalone
  • Combinable with any PAD service

Honest information

What this service
is — and isn't.

A top-up adds refrigerant to a low system. That is not the same as a full regas. We are clear about the difference upfront so there are no surprises on the day.

What's included
  • ✓ Low-side pressure check before we add anything
  • ✓ Refrigerant top-up (R134a or R1234yf systems)
  • ✓ Post-fill performance check — you should feel it immediately
  • ✓ Honest assessment — if the system has a bigger fault, we'll tell you
  • ✓ Suitable where gradual charge loss over time is the cause
What's not included
  • ✗ Vacuum evacuation — removes moisture, needs specialist machine
  • ✗ Leak detection or leak repair
  • ✗ Compressor diagnosis or repair
  • ✗ Full regas (recovery + evacuation + precise recharge by weight)
  • ✗ Heat pump EV systems — see section below
Important — EV owners

Does your EV
have a heat pump?

Heat pump systems are fundamentally different from conventional AC. This top-up service is not compatible with them. Check before booking.

Heat Pump EVs Cannot Be Serviced With This Top-Up

Heat pump systems use the refrigerant circuit for both cabin heating and cooling — sometimes also for battery thermal management. They require F-Gas certified equipment, a proper recovery machine, and scan tool access to command the system into the correct mode before any work is done. A basic pressure top-up cannot be performed safely or reliably on these systems, and attempting it risks compressor damage.

EVs commonly fitted with a heat pump:

Tesla Model 3 (2021+) Tesla Model Y (all) Hyundai Ioniq 5 Hyundai Ioniq 6 Kia EV6 VW ID.3 / ID.4 (higher trims) BMW iX & i4 Polestar 2 (optional) Nissan Leaf 62kWh e+ BYD Atto 3 MG4 Trophy Extended Range

Common questions

Air con questions.
Short answers.

No. F-Gas regulations apply to fluorinated greenhouse gases — pure R134a and R1234yf refrigerants in their HFC form. The refrigerant used in this top-up is a hydrocarbon-based alternative, which is specifically outside the scope of F-Gas legislation. Neither PAD nor you need an F-Gas certificate to use it. The one exception is heat pump EV systems — those cannot be serviced with this product regardless, and do require F-Gas certified equipment. For conventional AC systems on ICE vehicles and most EVs, no licence is needed on either side.
No — and that distinction matters. A full regas recovers the existing refrigerant, pulls a vacuum to remove moisture from the system, then recharges to the exact factory specification by weight using a dedicated AC machine. This top-up service adds refrigerant to a system that is low. It is effective when gradual charge loss over time is the cause of weak cooling. It will not fix a system that has leaked rapidly, has moisture contamination, or has a compressor fault. We'll tell you honestly if what you need is more than a top-up.
If your air con was working well previously and has gradually been blowing less cold air over the past year or two, low refrigerant is the most likely cause. If it stopped suddenly — especially with a noise or a warning light — there may be a compressor or electrical fault. If you're not sure, WhatsApp us with your reg and a description of what's happening and we'll advise whether a top-up is likely to fix it before you spend money on a visit.
Most cars made before 2016–2017 use R134a. Most built after that date use R1234yf. There is a sticker under the bonnet near the AC system stating which type. If you can't find it, include your registration when booking and we'll confirm before arriving — we bring both types so there's no wasted journey.
It works on EVs with conventional AC systems — this includes most first-generation EVs such as the Nissan Leaf 24kWh and 30kWh, Renault Zoe, and the Mitsubishi Outlander PHEV. It does not work on EVs fitted with a heat pump. See the heat pump section above for the list of affected models, and contact us if you're unsure about your specific vehicle.
We check pressure before adding anything. If your system is already correctly charged, nothing goes in — but the callout fee still applies. We'd rather spend two minutes checking than add refrigerant your car doesn't need. If the pressure is fine and the AC still isn't cold, we'll let you know what the likely cause is and what to do next.
Possibly for a short time. If your system has a minor slow leak — a deteriorating O-ring, for example — a top-up may restore cooling for a season. But it is not a repair; the leak continues and the system will eventually go low again. We don't use kits that contain sealant, as these can contaminate professional AC machines if a garage works on the car later. If a leak is confirmed or suspected, we'll tell you that clearly so you can decide whether a proper repair is worth pursuing.
