❄️ Does Freon Wear Out? The Complete Guide to AC Refrigerant Myths & Leaks For more than 28 years, John’s Heating, Cooling, and Appliance Repair has been the trusted choice for homeowners and businesses across Fayetteville, Peachtree City , Newnan , Griffin , Sharpsburg , Senoia , Tyrone , Zebulon , and South Metro Atlanta . One of the most common questions we hear is: 👉 “Does Freon wear out in my air conditioner like motor oil in a car?” The short answer: No. Refrigerant doesn’t wear out — it leaks. In this guide, we’ll bust the myths, explain the science, and show you why leaks are the real problem — plus how our team fixes them the right way. 🔍 Part 1: Why People Think Freon “Wears Out” When an air conditioner stops cooling, it’s easy to assume the refrigerant (often called Freon) just “ran out.” The logic makes sense — cars need oil changes and fluid top-offs. But refrigerant doesn’t work that way. How Refrigerant Really Works Closed-Loop System – Refrigerant runs in a sealed cycle, absorbing and releasing heat. It isn’t consumed. No Combustion – Unlike fuel or oil, refrigerant doesn’t burn or break down. Constant Cycle – The same refrigerant circulates through compression and expansion, year after year. 👉 If your AC is low on refrigerant, it’s not because it wore out — it’s because it escaped through a leak. ❄️ Part 2: Why Leaks, Not Wear, Cause Problems Refrigerant leaks are the real issue. Once refrigerant escapes, your AC loses efficiency and struggles to keep up with the summer heat in Georgia. Common Signs of a Refrigerant Leak Warm air blowing from vents Ice buildup on coils or refrigerant lines Hissing or bubbling noises near the unit Higher electric bills despite poor cooling The Cost of Ignoring a Leak Burned-out compressor – one of the most expensive AC repairs Energy bills up 30–50% – wasted money every month Poor indoor air quality – sticky, uncomfortable air System breakdowns – failure right when you need it most 👉 Just “topping off” Freon doesn’t solve the problem. It’s a temporary band-aid that guarantees you’ll be calling again. 🔬 Part 3: The Science of Refrigerant Refrigerant is designed to last the entire lifespan of your AC system. It circulates through indoor and outdoor coils, absorbing and releasing heat. It doesn’t get used up or burned. It simply changes state — liquid to gas and back again. If levels are low, the system is leaking. Period. 👉 Learn more about our Air Conditioning Repair in Peachtree City page. ❄️ Part 4: Why Honest Repairs Beat “Top-Offs” Unfortunately, some HVAC companies keep homeowners stuck in the Freon myth. They’ll top off refrigerant year after year without fixing the actual leak.

No. If refrigerant levels are low, it means there’s a leak. How long does refrigerant last? The entire life of your system — unless it escapes. Can I add more refrigerant? Not without sealing the leak. Otherwise, it will just leak out again. What happens if I ignore a leak? Expect higher bills, poor cooling, and eventual compressor failure. ✅ Final Takeaway Refrigerant doesn’t wear out. If your AC is low, it’s leaking — and leaks require professional repair.
