Air-con re-gas in Walsall
Weak cooling, misting or a musty smell? We re-gas both older R134a and newer R1234yf systems, and we'll tell you honestly which one your car needs. Based in Walsall, serving the whole West Midlands.
Signs your air-con needs a re-gas
Weak or warm airflow
The air-con runs but never gets properly cold — usually the first sign refrigerant has dropped.
Misting or damp smells
A musty smell or misted windows when the air-con is on can point to low refrigerant or a system fault.
Air-con clutch not engaging
If the compressor won't kick in at all, the system may have lost too much refrigerant to run safely.
Which gas is my car?
A rough reg-year guide — we always confirm the exact gas from your car's own label before booking any work.
R134a — typically pre-2013
The older refrigerant, used across most cars registered before roughly 2013. Cheaper gas, so a re-gas typically costs less.
R134a re-gas
Call with your registration for an exact quote.
R1234yf — 2013 onwards, mandatory from 2017
The newer, more environmentally-friendly refrigerant, phased in from around 2013 and mandatory on new type-approvals from 2017. The gas itself costs roughly 10x more than R134a, which is reflected in the price.
R1234yf re-gas
Costs more than R134a, reflecting the gas's higher cost — call with your registration for an exact quote.
What a re-gas involves
We check the system for leaks and confirm the correct refrigerant for your specific car, recover any remaining gas, evacuate the system fully, then refill to the manufacturer's exact specification with the correct oil — finishing with a performance check to confirm it's blowing cold before you drive away.
Common questions
What's the difference between R134a and R1234yf?+
R134a is the older refrigerant, used in most cars before roughly 2013-2017. R1234yf is the newer, more environmentally-friendly gas that became mandatory on new type-approvals from 2017 — it's chemically different and costs roughly 10x more per kilogram than R134a, which is why an R1234yf re-gas is typically pricier.
Which gas does my car use?+
As a rough reg-year guide: most cars registered before 2013 use R134a; most from 2017 onwards use R1234yf; cars in between vary by manufacturer and model. The exact gas is confirmed from your car's own under-bonnet air-con label or the manufacturer's data — we check this before booking any work so there's no guessing.
How much does an air-con re-gas cost?+
R1234yf costs roughly 10x more per kilogram than R134a, so an R1234yf re-gas typically costs more than an R134a one — call with your registration and we'll confirm the exact price for your gas type.
How often does air-con need re-gassing?+
Air-con systems naturally lose a small amount of refrigerant over time, even with no leak. Most manufacturers recommend a check every 1-2 years — if performance has noticeably dropped, it's worth booking a check regardless of when it was last done.
What does the re-gas process involve?+
We first check the system for leaks and confirm the correct refrigerant type for your car, then recover any remaining gas, evacuate the system, and refill it to the manufacturer's exact specification along with the correct oil. A quick performance check confirms it's blowing cold before you drive away.
