Overview
Air con regas, vacuum and leak checks, and climate control fault-finding for R134a and R1234yf systems.
Air conditioning is not only about summer. In a damp climate it is the quickest way to dry the air inside the car, which is why a working system clears a misted windscreen in seconds while a failed one leaves you wiping the glass with a sleeve.
Every system loses a little refrigerant each year through hoses, seals and the compressor shaft seal. As the charge drops, cooling fades gradually and the compressor works harder with less of the oil that travels around the system with the gas. Most drivers only notice once the air coming out is barely cooler than outside.
Mark starts by finding out why the system is not cooling. A regas puts the correct weight of refrigerant back in; if the system was empty, it is checked for leaks first so you are not paying to refill something that will be flat again in a few weeks.

In depth
What you should know about air conditioning
R134a or R1234yf — why it matters
Cars built before roughly 2017 mostly use R134a refrigerant. Newer models generally use R1234yf, which has a far lower environmental impact. The two are not interchangeable: they use different service connectors, different equipment and different oils, and mixing them is not permitted.
Your car's refrigerant type and the correct charge weight are printed on a label under the bonnet. That figure, not a guess, is what the system is filled to.
Why a regas is not always the answer
If a system has lost most of its charge in a short time, there is a leak. Common culprits are condensers damaged by stones at the front of the car, perished O-rings at pipe joints and worn compressor seals. Refilling without finding the leak just puts the problem off.
Holding a vacuum before recharging shows whether the system is sealed. Where a leak is found, you are told where it is and what a repair would involve before anything else is done.
Use it in winter too
Running the air conditioning for ten minutes or so every week, all year round, circulates the oil that keeps compressor seals supple. Systems left off for an entire winter are more likely to develop leaks and seized compressors.
Did you know?
Switching the A/C on with the heater set to warm is the fastest way to clear a misted windscreen. The system dries the air first, then the heater warms it.
On VW, Audi, ŠKODA & SEAT
Many VW, Audi, ŠKODA and SEAT models use Climatronic automatic climate control and clutchless compressors governed by a regulating valve. When cooling fails, ODIS shows pressure sensor readings, compressor control values and flap motor positions, so Mark can tell a gas problem from an electrical one before anything is replaced.
- Climatronic and Climatic fault codes read and cleared through ODIS
- Flap motor basic settings run after battery disconnection or panel replacement
- Compressor regulating valve faults on clutchless VAG compressors diagnosed
- Air quality and temperature sensor values checked in live data
Every other make, too
Air conditioning checks and regassing for Ford, Vauxhall, Toyota, BMW, Mercedes-Benz, Hyundai, Kia, Nissan and other makes, using the refrigerant and oil each system is designed for.
