The Truth About Freon: Myths Homeowners Still Believe

If we had a dollar for every time we heard, “It just needs more Freon”, we could retire and spend our days on a beach somewhere cooler than Houston in August.

But here’s the deal — most of what you’ve heard about Freon (and other refrigerants) is about as accurate as a weather forecast from 1987. Let’s clear the air.

First Things First: What Is Freon?

Freon is actually a brand name, like Kleenex or Band-Aid, but it’s become shorthand for “refrigerant” in general. Refrigerant is the chemical in your AC that absorbs heat from inside your home and dumps it outside.

If your AC were a sandwich, refrigerant would be the peanut butter — it’s not the bread, it’s not the jelly, but without it, you’ve just got a sad pile of bread.

Myth #1: Freon Gets Used Up Over Time

Nope. Refrigerant doesn’t get “used up” like gas in a car. If your AC is low, it’s because there’s a leak. Adding more without fixing the leak is like topping off a leaky gas tank — you’ll be right back where you started (but poorer).

Myth #2: Adding More Freon Instantly Makes the Air Colder

Not necessarily. If there’s a bigger problem — like a failing compressor or airflow issues — topping off the refrigerant won’t solve it. It’s like putting more sugar in bad coffee. Still bad.

Myth #3: Any Refrigerant Will Work in Any System

Your AC is picky. You can’t just throw in whatever’s on sale. Using the wrong refrigerant can cause major damage and void your warranty faster than you can say, “I thought it’d be fine.”

When Refrigerant Really Is the Issue

• Warm air blowing from vents

• Hissing or bubbling noises

• Ice on the evaporator coil

• Sky-high energy bills for no good reason

The 2025 Refrigerant Rule Change

Starting January 2025, R-410A (a common refrigerant) is being phased out in favor of more eco-friendly options like R-454B and R-32. Translation: if your system is older, now’s the time to plan ahead before costs go up and parts get scarce.

Bottom Line

If you suspect a refrigerant problem, call a pro (like us) to find and fix the leak. Otherwise, you’re just pouring money into the air… literally.
