Car Air Conditioning Not Cold in Ashford? Causes & What It Costs to Fix (2026)

By Salek Tyre & Mechanic · Ashford, TW15

If your car's air conditioning has stopped blowing cold air, the most common cause is low refrigerant and in most cases an AC recharge sorts it quickly for £50–£80. Here's how to tell what's wrong and what you can expect at Salek in Ashford TW15.

Why is my car air conditioning not cold?

There are several reasons a car AC stops cooling, ranging from a straightforward recharge to a more involved repair. The most common causes, in order of likelihood:

1. Low refrigerant (most common)

AC refrigerant slowly escapes from the system over time even a perfectly healthy system loses a small amount each year through micro-permeation. After two to three years without attention, the refrigerant level drops below what the system needs to produce cold air. An AC recharge restores the correct level and is the fix for most AC problems on cars in otherwise good condition.

2. Refrigerant leak

If the system has lost refrigerant faster than normal, or if a recharge hasn't lasted as long as it should, there may be a leak typically from a joint, O-ring, or the condenser. We use leak-detection dye during recharge to identify any active leak. A minor leak can often be sealed; a significant condenser or compressor leak requires a part replacement.

3. Compressor fault

The AC compressor circulates refrigerant through the system. If it's failed or the clutch that engages it is worn, the system won't cool regardless of refrigerant level. You may notice the AC click on briefly then cut out, or hear a clunking noise when the AC is switched on. Compressor replacement is a more involved repair.

4. Blocked or dirty cabin air filter

A heavily blocked cabin filter reduces airflow through the vents significantly. The AC may still be cooling the air, but so little gets through that it feels warm. Cabin filter replacement is inexpensive and worth checking if your airflow feels weak. This is checked as part of a full car service see our full service guide.

How much does an AC recharge cost in Ashford?

An air conditioning recharge at Salek costs in the region of £50–£80 for most standard vehicles. This includes recovering any remaining refrigerant, vacuuming the system, and recharging to the correct level with fresh refrigerant and lubricant oil.

How long does an AC recharge take?

The recharge process takes around 45–60 minutes on our specialist AC machine. You can wait at the garage while it's done.

Should I run my AC in winter?

Yes running the AC for 10 minutes once a week, even in winter with the heat on, keeps the seals lubricated and prevents the refrigerant from separating. Cars that sit with the AC unused for an entire winter are more likely to notice problems in spring. It's a good habit that costs nothing.

Is it safe to drive with a faulty AC?

A non-functioning AC is not a safety hazard in itself, but it's uncomfortable in summer heat and a severely fogged windscreen in winter is dangerous. AC is used by the demister on most cars, so a faulty system may leave you with slower demisting in cold weather. Get it checked before the weather turns.
