Regas Service
Restoring Your Vehicle's Climate Performance
- Did You Know Your Air Con Works Hard All Year Round? Don't just think summer! Your car's air conditioning system is also brilliant for demisting your windscreen in winter. It generates dry, warm air that cuts through condensation far quicker than regular heating, ensuring clear visibility for safer driving all year long.
Is your vehicle’s air conditioning no longer as cold as it used to be? Perhaps the fan is blowing, but the refreshing chill you once relied on is gone? Over time, even perfectly sealed vehicle air conditioning systems can gradually lose refrigerant gas (up to 10-15% per year), leading to a noticeable drop in performance, increased fuel consumption, and potential damage to vital components like the compressor.
A professional regas service (also known as a recharge or re-gas) is essential to restore your AC system to its optimal operating levels. It’s not just about topping up the gas; it’s a comprehensive process to ensure your system is healthy, efficient, and ready to deliver consistent comfort.
The Importance of a Professional Regas Service
- Restored Cooling Performance: Get that icy cold air back, ensuring a comfortable cabin in any weather.
- Improved Efficiency: A correctly gassed system works less hard, reducing strain on your engine and potentially improving fuel economy.
- System Longevity: Sufficient refrigerant also carries lubrication for the compressor. A low gas level means reduced lubrication, leading to premature wear and potentially very costly component failures.
- Compliance & Environmental Responsibility: Proper regassing involves the safe and legal handling of refrigerants, preventing harmful gases from being released into the atmosphere.
Our Comprehensive Regas Service: Expertise Across All Refrigerant Types
At Alpinair, with over 50 years of specialist experience, we are equipped with the latest technology and certified expertise to perform professional regas services on virtually any vehicle, using all modern and emerging refrigerant types. We don’t just regas; we ensure your system is properly diagnosed and charged for peak performance and longevity.
Our capabilities include the full range of commonly used and specialist refrigerants:
- R134a: The long-standing industry standard refrigerant found in the vast majority of vehicles on UK roads, from cars and vans to commercial vehicles and older plant machinery.
- R1234yf: The newer, environmentally friendlier refrigerant mandated in vehicles manufactured from 2017 onwards. It has a significantly lower Global Warming Potential (GWP) and requires specific, dedicated equipment for safe and effective handling.
- R744 (CO2): The Specialist’s Choice: As vehicles evolve, particularly Electric Vehicles (EVs) and certain high-performance or commercial vehicles, R744 (Carbon Dioxide) is increasingly being adopted as a natural refrigerant. Alpinair possesses the specialist equipment, advanced training, and in-depth expertise required to safely and effectively service and regas R744 systems. This capability sets us apart, ensuring we can handle the cutting-edge of automotive climate control.
- Older & Obsolete Systems (e.g., R12): While we cannot regas with R12 due to environmental regulations, we have the specialist equipment to safely recover and manage these older refrigerants from classic or vintage systems, allowing for conversion or repair.
We provide regas services for all types of vehicles:
- Cars (Modern, Classic, EV/Hybrid)
- Vans & Trucks
- Commercial Vehicles (including refrigerated units where applicable)
- Social Welfare Vehicles
- Motorhomes & Campervans
- Party Buses & Executive Coaches
Our Meticulous Regas Process
Our detailed approach ensures your AC system is not just refilled, but properly checked for optimal health:
- Initial System Performance Check: We begin by assessing your current AC performance, checking vent temperatures, and listening for unusual noises.
- Refrigerant Recovery: All existing refrigerant (old gas and any contaminants) is safely and legally recovered from your system using specialist equipment, adhering to strict F-Gas regulations.
- Vacuum & Leak Test: The system is placed under a vacuum to remove any moisture and air, which can cause corrosion and hinder performance. We then conduct a vacuum decay test and, for a more thorough check, a nitrogen pressure test to pinpoint even the smallest leaks that could lead to future gas loss.
- Oil & UV Dye Injection: The correct amount of system-specific lubricant oil is added to ensure proper compressor function and longevity. A UV dye can also be injected to help detect future leaks.
- Precise Refrigerant Recharge: Your system is accurately recharged with the correct type and quantity of refrigerant (R134a, R1234yf, or R744) as specified by the vehicle manufacturer.
- Final Performance Test: We run the AC system, checking pressures, temperatures, and overall performance to confirm it’s delivering optimal cooling.

FAQ's
How Do I Identify My Vehicle’s Air Con Gas Type?
Knowing your vehicle’s air conditioning gas type is crucial for correct servicing, as different refrigerants require specific equipment and handling. The two most common types you’ll encounter in the UK are R134a and the newer R1234yf, with R744 (CO2) appearing in some very modern or specialist vehicles.
- Before roughly 2017/2018: Most vehicles will likely use R134a.
- From roughly 2017/2018 onwards: Vehicles will almost certainly use R1234yf, as this became the legally mandated refrigerant for new vehicle types.
- Very New/Premium/Electric Vehicles: A small but growing number of vehicles, particularly certain new premium models or Electric Vehicles (EVs), might use R744 (CO2).
When in Doubt, Ask a Specialist!
If you’re unsure, or cannot locate the label, it’s always best to consult with a professional vehicle air conditioning specialist like Alpinair. We have the necessary diagnostic tools and expertise to correctly identify the gas type and service your system safely and efficiently. Never attempt to mix or top up refrigerants yourself, as this can cause serious damage to your system and pose a safety risk.
Your time is valuable to us. While we aim for most repairs to be completed the same day, sometimes unforeseen issues can arise during the service. If that happens, we'll notify you immediately and keep you fully updated on the progress.
