AC refill with R134a (cars 1990–2017)

AC refill with R134a — for cars 1990–2017

R134a (1,1,1,2-tetrafluoroethane) was the standard refrigerant in almost every new car sold in Europe from the early 90s until the EU MAC Directive (2006/40/EC) phased it out for new models from 1 January 2017. That means most cars on Norwegian roads today still have R134a systems — and you can safely get a service or refill from us at any time. The refrigerant is non-flammable, has low requirements for handling equipment, and is still fully legal to top up in existing systems.

Why does the AC get worse over time?

Even a perfectly sealed system naturally loses 10–15% of its refrigerant per year through diffusion — molecules gradually seep through hose walls and O-rings. After 4–5 years the system typically has half its original charge left, and cooling performance noticeably drops. In addition, compressor oil carries away a few grams with every kilometre driven. That's why we recommend a full AC service every two years as preventive maintenance, not just when the problem is already there.

How we perform the R134a refill

We connect the car to an automatic service station that first identifies the refrigerant type to avoid mis-charging. The process then runs automatically: vacuum recovery of all existing refrigerant and compressor oil, the vacuum pump runs for 20–30 minutes to remove moisture and air, a leak test verifies that the system holds vacuum, and finally the correct amount of oil and R134a is refilled according to the vehicle manufacturer's specification (typically 400–700 grams). The whole job takes 30–60 minutes depending on the car, and we always provide a fixed quote before starting.

What's included in the service?

• Refrigerant identification to avoid mis-charging
• Recovery and recycling of old R134a (closed-loop system)
• System evacuation for 20–30 minutes
• Leak test under vacuum
• Top-up of compressor oil (PAG oil) as needed
• Refill of the correct R134a amount per manufacturer spec
• Function test with temperature reading at the vents

Price and what affects it

The price varies primarily with how much refrigerant your car needs. Smaller passenger cars take 400–500 grams, while larger SUVs and vans may need 700–900 grams. R134a itself is cheap per kilo, so the material cost is moderate — labour and equipment make up the bulk. We always give a fixed price based on your model before we start, so you know exactly what you'll pay.

When more than a refill is needed

If the vacuum leak test shows that the system doesn't hold, we have to find the leak first. Common causes are brittle O-rings, condenser leaks after stone chips, or fatigued seals at the compressor shaft. We then bring in our leak-search service before refilling — there's no point in charging a system that leaks, and refrigerant released into the atmosphere is both expensive and an environmental burden.
