Your car's air conditioning system is one of those things you only notice when it stops working — especially on a hot summer's day. When the cold air starts to fade, many drivers are confused about what they need: a regas, a full service, or something else entirely.
At AVS Bransgore, we get asked this question regularly. Here is the honest answer about AC regassing versus full AC servicing, and how to know which one your car needs.
What Is an AC Regas?
An AC regas (or recharge) is a straightforward procedure where we remove the old refrigerant from your air conditioning system and replace it with fresh refrigerant. It is the most common AC service and the one most drivers need.
Air conditioning systems lose a small amount of refrigerant every year — typically 5 to 10 percent. After three to four years, this loss becomes noticeable. The system still works, but it does not get as cold as it should. A regas restores the refrigerant to the correct level and brings the cooling power back.
A regas takes about 45 minutes and costs from £60 plus VAT at AVS Bransgore. We use the correct refrigerant for your vehicle — usually R134a for older cars or R1234yf for newer models.
When you need a regas: Your air conditioning is not as cold as it used to be, but it still works. The system has no visible leaks.
What Is a Full AC Service?
A full AC service is more comprehensive than a regas. It includes:
- Removal and replacement of the refrigerant
- Replacement of the receiver drier (a component that removes moisture from the system)
- Flushing the system to remove any debris or contamination
- Checking all seals and connections for leaks
- Testing the system thoroughly
A full AC service takes 2 to 3 hours and costs from £150 to £250 plus VAT, depending on your vehicle.
When you need a full service: Your air conditioning has failed completely or is barely working. You suspect a leak in the system. Your car has not had an AC service in more than five years. You have had a collision that may have damaged the AC system.
AC Leaks: The Hidden Problem
If your air conditioning loses refrigerant quickly (within a few months of a regas), you probably have a leak. A small leak might be in a hose connection; a larger leak could be in the compressor, condenser, or evaporator.
If we suspect a leak, we can perform a leak test using a UV dye. This shows exactly where the refrigerant is escaping. Small leaks can often be fixed by replacing a hose or tightening a connection. Larger leaks may require component replacement, which is more expensive.
How to Keep Your AC Healthy
- **Run your AC regularly:** Use it for at least 10 minutes every week, even in winter. This keeps the compressor lubricated and the seals in good condition.
- **Get it serviced every two years:** Regular servicing prevents problems and keeps your AC working efficiently.
- **Check for leaks:** If your AC loses cooling power quickly after a regas, get it checked for leaks.
- **Keep your condenser clean:** The condenser (the radiator-like component at the front of your car) can get blocked with dirt and bugs. A clean condenser helps your AC work more efficiently.
The Bottom Line
If your air conditioning is not as cold as it used to be, start with a regas. It is the most common fix and the most affordable. If the problem persists or you suspect a leak, a full service and leak test will identify what is wrong.
