Frequently Asked Questions
Our air con regas starts from £80 + VAT for R134a systems, and £120 + VAT for R1234yf systems. The exact price depends on the refrigerant your vehicle uses.
It depends on the age and model of your vehicle — most cars manufactured after 2017 use R1234yf, while older vehicles typically use R134a. If you’re not sure, send us your vehicle registration and we’ll check for you.
A standard air con regas usually takes around 30–45 minutes, so in most cases we can have you back on the road the same day.
This can be caused by low refrigerant, a leak, a faulty compressor, a pressure sensor fault, or an electrical issue. A regas will top up the refrigerant, but if there’s an underlying fault, we’d recommend booking a diagnostic check first.
No — a regas only recharges the refrigerant and does not repair leaks or faulty components. If a leak is causing your system to lose gas, we’d need to diagnose and repair that separately.
