If your car’s air conditioning isn’t blowing as cold as it used to, one of the first culprits that comes to mind is low refrigerant. But here’s the thing—your car’s AC system is a sealed, closed-loop system, meaning refrigerant isn’t something that just *disappears* over time like engine oil or windshield washer fluid.
So, if your refrigerant level is low… you almost certainly have a leak.
Why Can’t You Just “Top Off” the Refrigerant?
You might see DIY refrigerant recharge kits at auto parts stores and think, “Why not just add more and call it a day?” Here’s the problem:
- Refrigerant doesn’t get “used up”—it circulates indefinitely in a properly functioning system.
- Adding more without fixing the leak is like pouring water into a bucket with a hole—it’ll just leak out again.
- Overcharging the system can cause damage to the compressor, leading to costly repairs.
The only proper fix is to locate the leak, repair it, and then recharge the system with the correct amount of refrigerant.
Common Signs of an AC Refrigerant Leak
How do you know if your AC is losing refrigerant? Watch for these red flags:
✅ Weak or warm airflow (even when set to max cold)
✅ Hissing or bubbling noises from the AC system
✅ Visible oily residue around AC fittings or hoses (refrigerant leaks often leave traces)
✅ AC works fine at first, then loses cooling power
How Do You Find (and Fix) an AC Leak?
Since refrigerant leaks can be tiny and hard to spot, professional diagnosis is key. At Hillside Auto Repair, our certified technicians use state-of-the-art equipment to:
🔍 Perform UV dye tests (injecting fluorescent dye to pinpoint leaks)
🔍 Use electronic leak detectors (for precise identification)
🔍 Check O-rings, seals, and connections (common leak points)
Once we find the leak, we repair or replace the faulty component, vacuum-test the system to ensure no other leaks exist, and recharge it with the exact manufacturer-specified refrigerant amount.
