Summer is here, and if your car's air conditioning is blowing warm instead of cold, you are not alone. AC problems are one of the most common issues we see in summer, and the good news is that most of them are easily fixed with a regas. Here is what you need to know about car air conditioning and why regular maintenance matters.
How Car Air Conditioning Works
Your car's air conditioning system circulates refrigerant (usually R134a) through a sealed loop. The refrigerant absorbs heat from inside your car and releases it outside, keeping the cabin cool. The system also contains oil that lubricates the compressor and other components.
Why Your AC Stops Working
Air conditioning systems lose a small amount of refrigerant every year — this is normal. After three to five years, the loss becomes noticeable, and your AC will not blow as cold as it used to. If your AC is blowing warm or not cooling at all, a regas will almost certainly fix it.
Other reasons for AC failure include: (1) A leak in the system (requires repair, not just regas), (2) A faulty compressor (expensive repair), (3) A blocked condenser (can be cleaned), or (4) An electrical fault (requires diagnosis).
The Regas Process
A regas is a straightforward procedure that takes about 45 minutes. Our technician will: (1) Connect diagnostic equipment to measure the current refrigerant level, (2) Extract any old refrigerant and oil from the system, (3) Flush the system to remove contaminants, (4) Add fresh refrigerant to the correct level, (5) Add new oil to lubricate the compressor, and (6) Test the system to confirm it is working properly.
Cost and Frequency
A standard AC regas costs from £60 to £100 depending on your vehicle and whether any repairs are needed. We recommend regassing every two to three years to maintain optimal performance. If your AC has not been serviced in five years or more, a regas will make a huge difference to your comfort on long summer drives.
DIY AC Regas Kits
You can buy DIY AC regas kits online, but we do not recommend them. These kits are difficult to use correctly, and if you overcharge the system, you can damage the compressor (a £1,000+ repair). Professional equipment ensures the correct amount of refrigerant is added, and our technicians can identify leaks or other problems that a DIY kit cannot.
Preventative AC Maintenance
To keep your AC in top condition: (1) Run it for at least 10 minutes every week, even in winter (keeps seals lubricated), (2) Have it regassed every two to three years, (3) Get it checked if it stops blowing cold, and (4) Have any leaks repaired immediately.
