Air Con Regas in Park Royal

Cold air comes back by weight, not guesswork. We recover whatever refrigerant your system still holds, weigh it so you can see how much had escaped, vacuum test the circuit for leaks, then recharge to the exact figure the manufacturer specifies. Both R134a and R1234yf systems are handled here, with an anti-bacterial cleanse available if the vents smell musty.

What is air con regas?

Air conditioning is a sealed circuit rather than a tank that gets topped up. The compressor pressurises refrigerant, the condenser at the front of the vehicle sheds that heat into passing air, a receiver drier pulls moisture out, and an expansion valve drops the pressure so the refrigerant boils inside the evaporator behind the dashboard, taking heat out of the cabin air blown across it. The refrigerant also carries the oil that lubricates the compressor, so a circuit running low is a compressor running dry, which is why an ignored system eventually turns into an expensive one. Charge escapes slowly through hoses and O-ring seals whether or not a fault exists, so cooling fades across years rather than failing overnight. Older cars use R134a, newer ones R1234yf, and the two are not interchangeable.

How we carry out air con regas

We identify which refrigerant your vehicle takes and look up the exact charge weight it should be holding, then connect the station to the high and low pressure service ports. The old refrigerant is recovered and weighed, so you learn how much had actually leaked away since last time. With the circuit empty we pull it down to a vacuum and hold it there, watching whether pressure creeps back up, which is the test that catches a leak before a single gram of fresh gas goes in. If it holds, the system is charged by weight along with fresh lubricating oil and tracer dye. We then run it and measure the temperature at the centre vents against the outside air before handing the keys back.

• Musty smell as the fan starts
• Windscreen demists far slower than before
• Air con clicks on and off constantly
• Cabin only cools once you are moving
• No recharge in over two years

What you get from air con regas

• Charged by weight to manufacturer specification

• Vent temperature verified before you leave

Air con regas and West London driving

Air conditioning works hardest when a vehicle is barely moving, which describes an unfortunate amount of driving in this part of London. Sitting on the Hanger Lane gyratory, or queuing where the A406 North Circular meets the A40 Western Avenue, there is no ram airflow through the condenser at all, only what the cooling fans can drag through, so the system has to dump cabin heat with the least help it ever gets. A charge that coped last summer will blow merely cool in that queue. Slow traffic along Scrubs Lane and the Harrow Road on a humid afternoon finds exactly the same weakness.

Why choose Park Royal Tyre & Alignment Centre for air con regas

A recharge is only worth as much as the leak test in front of it and the weighing that follows. We are an RAC Approved Garage and an AA Approved Garage, equipped for both R134a and R1234yf, which are genuinely separate systems needing separate service equipment. Your circuit is charged to the manufacturer's stated weight rather than filled until it feels colder, and if it will not hold vacuum you are told there is a leak instead of watching fresh gas disappear into it.
