Car air conditioning is more than just a luxury—especially in a hot city like Dubai, it’s a necessity. But when it’s time for a car AC gas refill, many car owners unknowingly make simple but costly mistakes.
Incorrect handling can damage your AC system, reduce cooling efficiency, or even lead to major repairs. In this blog, we’ll highlight the most common car AC gas refill mistakes and provide expert tips on how to avoid them.
Top Car AC Gas Refill Mistakes to Avoid
1. Refilling Without Fixing the Leak
The Mistake: Simply topping off low refrigerant without checking for leaks.
Why It’s a Problem: If your AC system is leaking, the new gas will escape again—wasting money and harming the environment.
✅ Expert Tip: Always get a leak test or dye test before refilling. A professional garage can detect and seal leaks properly.
2. Overcharging the AC System
The Mistake: Adding too much refrigerant, thinking “more gas = colder air.”
Why It’s a Problem: Overcharging puts extra pressure on the compressor and may cause it to fail.
✅ Expert Tip: Always recharge using manufacturer-specified levels and precise equipment.
3. Using the Wrong Type of Refrigerant
The Mistake: Mixing or using the incorrect AC gas (e.g., R134a in a system designed for R1234yf).
Why It’s a Problem: It can cause system failure, inefficient cooling, and void your warranty.
✅ Expert Tip: Check your car’s label or manual, and only use the correct refrigerant. Always let professionals handle newer gases like R1234yf.
4. DIY Refills Without Proper Tools
The Mistake: Using over-the-counter refill kits at home without proper gauges or vacuum pumps.
Why It’s a Problem: You can’t measure accurate pressure levels, leading to overcharge or underperformance.
✅ Expert Tip: Leave AC refills to certified technicians with proper tools like recovery machines and manifold gauges.
5. Ignoring AC Filter and Cabin Filter Condition
The Mistake: Refilling gas without checking the AC filter or cabin filter.
Why It’s a Problem: A clogged filter reduces airflow and cooling, no matter how much gas you add.
✅ Expert Tip: Ask your garage to inspect or replace the cabin filter during every AC service.
6. Skipping System Flushing
The Mistake: Not flushing the system after a compressor or major AC component replacement.
Why It’s a Problem: Residual debris or old oil can damage new parts and lead to inefficient cooling.
✅ Expert Tip: Flush the system when replacing key components or switching gas types.
7. Forgetting to Replace O-Rings and Seals
The Mistake: Old or cracked seals are reused during service.
Why It’s a Problem: Leaky seals can cause refrigerant loss and lead to repeat refills.
✅ Expert Tip: Replace O-rings and seals with every major AC service to ensure a tight seal.
