Is Your Car Air Con Blowing Warm? Why It Might Need More Than Just a Regas

When the warmer weather hits, the last thing you want is to turn on your vehicle’s air conditioning only to be greeted by a blast of lukewarm air. Many drivers assume that a weak AC simply needs a quick gas top-up, but the reality in the workshop is often a bit more involved.

Over time, vehicle air con systems naturally lose a small percentage of refrigerant each year, but leaks can also develop around seals, hoses, or the condenser due to vibration and road debris. If your system is struggling, running a simple regas without checking for underlying faults is only a temporary fix.

At our St Neots workshop, we use specialised equipment to test for leaks, safely drain old refrigerant, and restore your system properly. Whether you drive an older pre-2017 model or a newer vehicle, keeping your AC maintained also helps demist your windows quicker during winter dampness.
