Professional air con regas for all vehicles. R134a and R1234yf refrigerant. UV dye leak detection. Serving Norwich and all of Norfolk from our Ber Street garage.
Is your car's air conditioning blowing warm air, or not as cold as it used to be? A refrigerant regas is usually all it takes to restore full cooling performance. At Norwich Tyres & Auto Service on Ber Street, we carry out professional air con regas for all makes and models using both R134a and R1234yf refrigerant.
Over time, every air conditioning system gradually loses refrigerant — typically around 10–15% per year even with no visible leaks. As the refrigerant level drops, the system becomes less effective until it eventually stops cooling altogether. A regas involves recovering any remaining old refrigerant, checking the system for leaks, pulling a vacuum to remove moisture, and recharging the system to the manufacturer's specified level with fresh refrigerant and lubricating oil.
Modern vehicles built before 2017 typically use R134a refrigerant, while newer models use the updated R1234yf refrigerant. Our equipment handles both types, and we always use the correct refrigerant for your specific vehicle. We also add UV dye during the recharge process, which allows us to pinpoint any future leaks quickly and accurately using a UV lamp.
The most obvious sign is air conditioning that blows warm or only mildly cool air even on the coldest setting. You might also notice musty or damp smells when you first switch the air con on — this can indicate moisture has entered the system due to low refrigerant pressure. Other signs include the air con taking longer than usual to cool the cabin, the system cutting out frequently, or windows that take longer to demist in winter. If you notice any of these, it's worth booking a regas before the system fails entirely.
We recommend a regas every two to three years as routine maintenance, even if the air con still appears to be working. Keeping the refrigerant at the correct level reduces wear on the compressor, which is one of the most expensive components to replace. It's a small investment that protects a much bigger one.
We use a fully automatic air conditioning service machine that handles the entire regas process cleanly and accurately. First, we recover any existing refrigerant from the system — this is done in a closed loop so nothing is released into the atmosphere. We then run a leak test, pull the system down to a deep vacuum to remove any air or moisture, and recharge with the correct weight of fresh refrigerant plus lubricating oil. The whole process typically takes around 45–60 minutes, and you can wait in our customer area while we work.
Norwich drivers choose us for honest, straightforward service with no upselling or unnecessary extras. We'll tell you clearly what we find and what you need. If the system has a significant leak that means a regas won't hold, we'll tell you before we charge you for one. Call 07933 900901 to book your air con regas today.
Most manufacturers and technicians recommend regassing every two to three years. Air con systems lose refrigerant naturally over time even without a leak, so a periodic regas keeps performance at its best and protects the compressor from running low on lubricant.
R134a is the older refrigerant used in most vehicles manufactured before 2017. R1234yf is the newer, more environmentally friendly refrigerant required in vehicles manufactured from 2017 onwards. The two types cannot be mixed, and each requires different equipment. We carry both types and will always use the correct one for your vehicle.
We strongly advise against using DIY air con regas cans. They don't recover the old refrigerant first (which is a legal requirement), can't measure how much is already in the system, and may overfill it — causing damage to the compressor. A professional regas uses calibrated equipment and ensures the system is charged to the manufacturer's exact specification.
We add UV dye to the refrigerant during the regas, which makes any leaks visible under UV light. If we suspect a leak before regassing we'll test the system first. Minor leaks from seals can sometimes be treated with a specialist sealant added during the regas, while larger leaks from hoses or the condenser will need the relevant component replaced.
The regas process itself takes around 45–60 minutes. If we need to carry out additional leak testing or repairs, it may take a little longer. We'll always give you an accurate time estimate when you book.
