Common questions

Car air con, answered

Everything drivers ask us most, from how often to regas to what to do about a musty smell. Can't find your question? Get in touch and we'll answer it directly.

How often should I regas my car air conditioning?
A car's air conditioning loses roughly 10% of its refrigerant gas every year through normal use. Most cars benefit from a regas every two to three years to keep the air blowing properly cold.
Should I use my air con in winter?
Yes — it's one of the best things you can do for it. Air con dries the air, which is exactly what clears a misted windscreen fast, and running it for a few minutes each week through winter keeps the compressor seals lubricated so they don't dry out and leak. Skipping it all winter is one of the most common reasons a system needs a regas come spring.
Why do my windows still fog up even with the heater on full?
Heat alone just moves warm, damp air around — it doesn't remove the moisture causing the fog. Air con actively dries the air as it cools it, which is why switching it on alongside the heater clears a misted windscreen far faster. If it's still slow to clear, low refrigerant is often the cause.
How much does a car air con regas cost?
It depends on your vehicle and which gas it takes — older cars use R134a, newer cars (roughly 2017 on) use the pricier R1234yf. Get in touch or drop by and we'll confirm the exact cost before any work begins.
How long does an air con regas take?
Most regas and recharge jobs take around 45 to 60 minutes. We run a vacuum and pressure test first, so you leave knowing the system holds and the air is genuinely cold.
My air con smells bad. Can you fix that?
Yes. A musty smell usually means bacteria and mould in the system. Our ozone sanitisation treatment kills it at source and leaves the cabin fresh, often paired with a new pollen filter.
My regas didn't last. What's wrong?
If a regas drains quickly, there's almost always a leak. We use UV dye and electronic detection to trace it, then fix the cause so you're not paying to refill a system that won't hold.
Do you look after vans and work vehicles?
We do. Vans and small fleets are welcome, with flexible drop-off times to fit around a working week. Get in touch and we'll sort a schedule that suits.
