Auto AC Refrigerant Recharge

Professional R-134a and R-1234yf recharge service — the right amount, to factory spec. We recover, vacuum, and recharge — no shortcuts, no venting. 2-year / 24K-mile nationwide warranty.
What We Do
Refrigerant Recharge Done Right
A proper AC recharge is not a can of refrigerant from the parts store. A correct recharge means recovering the existing refrigerant, vacuum-testing the system for leaks, measuring oil content, and recharging to the manufacturer-specified amount by weight — not by pressure guess.
Using a cheap 'top-off' can makes three common mistakes: it overcharges systems (which damages the compressor), ignores refrigerant oil balance, and skips the vacuum test that would have caught the leak that drained the system in the first place.
At Lynn's we use professional recovery and recharge equipment for both R-134a (most vehicles through ~2014) and R-1234yf (most 2015+ vehicles). If your system is leaking, we'll find it — because recharging a leaky system is just paying to vent expensive refrigerant into the atmosphere.

Our Process
How We Fix It Right the First Time
Recover Existing Refrigerant
We extract and weigh any refrigerant still in the system — illegal to vent. This also tells us whether the system was low.
Vacuum & Leak Test
We pull a deep vacuum on the system and hold it. If vacuum doesn't hold, there's a leak — and we find it before recharging. Charging a leaky system wastes your money and our refrigerant.
Recharge by Weight
We recharge to the exact factory specification (by weight, not pressure) with the correct refrigerant type and oil balance. Then we verify vent temp and pressures under load.

Questions from Downey Drivers
Frequently Asked Questions
How often should I recharge my car's AC?
A properly working AC system should never need refrigerant added. If yours does, there's a leak — and just recharging it again isn't fixing anything. We find the leak, fix it, then charge the system properly.
What's the difference between R-134a and R-1234yf?
R-134a is the refrigerant found in most vehicles through roughly 2014. R-1234yf is the newer, EPA-mandated refrigerant found in most 2015+ vehicles. They are NOT interchangeable — and R-1234yf requires dedicated equipment. We service both.
Can I just use one of those DIY recharge cans from Walmart?
We strongly don't recommend it. Those cans frequently overcharge the system (damaging the compressor), contain leak-stop additives that can clog the expansion valve, and don't address the underlying leak. Save yourself the compressor replacement later.
How much does an AC recharge cost?
It depends on which refrigerant your vehicle uses — R-1234yf is significantly more expensive than R-134a. Call (562) 803-5611 for a quote specific to your vehicle.
Is recharge service warranted?
Every AC repair — including recharge — is backed by our 2-year / 24,000-mile nationwide warranty on parts and labor.
