Your Air Conditioning Questions, Answered
If you notice any of these common signs, it's time for a professional check-up. Ignoring these symptoms can lead to reduced efficiency and more costly repairs down the line.
-
Air Isn't Cold: The most obvious sign. The air blowing from your vents is cool at best, or even warm.
-
Unpleasant Odours: A persistent musty or damp smell indicates a build-up of bacteria and mould in the system.
-
Unusual Noises: Hissing, rattling, or clicking sounds when the AC is turned on can signal a failing compressor or other component issues.
-
Slow Demisting: Your windscreen takes much longer than usual to clear in damp or cold weather, as the AC is no longer effectively dehumidifying the air.
-
Weak Airflow: Even on the highest setting, the air coming from the vents feels weak.
Which Air Con Gas Does My Car Need?
As part of a global effort to protect the environment, vehicle manufacturers were required to switch to a new, more eco-friendly refrigerant gas. At Alpha MOT Centre, we are fully trained and equipped to service both the older and newer systems.
R134a (Older Gas)
Used in the vast majority of vehicles manufactured before 1st January 2017. This has been the industry standard for over two decades, and our technicians are experts in servicing these systems to restore their original cooling power.
R1234yf (Newer, Eco-Friendly Gas)
Required by law for all new vehicles manufactured since 2017 to meet stringent environmental regulations. This gas has a Global Warming Potential (GWP) that is over 99% lower than R134a. While the gas itself is more expensive, our price remains one of the most competitive in Essex.
Frequently Asked Questions
Most vehicle manufacturers recommend a full air conditioning service and regas every two years. Your system naturally loses around 10-15% of its refrigerant gas each year, so a biannual service ensures it remains efficient and prevents damage from low lubricant levels.
No. An air conditioning service is a specialist task that is not included in a standard MOT test or typically part of a routine annual vehicle service. It must be booked separately.
A standard regas service typically takes between 45 and 60 minutes to complete. You are welcome to wait in our comfortable reception area while our technicians carry out the work.
Our mandatory vacuum test will identify any significant leaks in the system. If a leak is found, we will not proceed with the regas, as this is environmentally irresponsible and would be a waste of your money. We will inform you immediately and can provide a separate, no-obligation quote for diagnosis and repair.
We strongly advise against this. DIY kits cannot remove the old, contaminated gas or, more importantly, the moisture that has built up in the system, which is a primary cause of corrosion and future failure. They also risk over-pressurising the system, which can cause serious and expensive damage to the compressor. A professional service is safer, more effective, and better value in the long run.
