Air Conditioning FAQ
How often should I regas my car air conditioning?
Most manufacturers recommend an aircon regas every 2–3 years to keep the system running efficiently. If your AC is blowing warm air, it may need recharging sooner.
How do I know if my car aircon has a leak?
Signs of a leak include poor cooling, hissing noises, or visible oily residue around AC components. We use professional leak detection equipment to find and fix the problem.
What’s the difference between R134a and 1234yf gas?
-
R134a – Used in most cars manufactured before 2017
-
1234yf – A newer, environmentally friendly gas required in most vehicles built after 2017
We service both types of gas at Brunel Motors.
Why does my aircon smell bad?
Unpleasant odors usually come from bacteria and mould in the vents. Our aircon cleaning service removes these contaminants, leaving your car fresh and hygienic.
Can you repair aircon systems as well as regas them?
Yes – we don’t just regas your aircon. Our team can diagnose and repair faults including compressors, pipes, seals, and condensers.
Does car aircon affect fuel economy?
Yes, running your AC can slightly increase fuel usage. However, if your system is low on gas or faulty, it can put more strain on components, which can increase fuel consumption further.
