What is R-22 refrigerant and why should I replace it?

If you’ve been told your AC system uses R-22 refrigerant, you might be wondering—what exactly is R-22, and why are so many homeowners replacing it?

Let’s break it down in simple terms.

What is R-22 Refrigerant?

R-22, also known as Freon, is a type of hydrochlorofluorocarbon (HCFC) refrigerant. It’s been used for decades in residential air conditioning systems and older HVAC units.

Back in the day, R-22 was the industry standard for cooling homes. But now, it’s become outdated—and for good reason.

Why Was R-22 Banned?

Here’s the deal: R-22 is harmful to the environment. Specifically, it contributes to ozone layer depletion. To tackle this issue, the Environmental Protection Agency (EPA) began phasing out R-22 under the Clean Air Act.

As of January 1, 2020, the production and import of R-22 in the U.S. were officially banned.

So, if your system still uses R-22, you’re relying on a refrigerant that is no longer being made—and that can lead to big issues.

The Rising Cost of R-22

Since R-22 is no longer produced, its supply is limited. That means:

R-22 prices have skyrocketed
It’s harder to find qualified technicians who service R-22 units
Future repairs will cost more—sometimes more than the unit is worth

At Expert Air, we often tell customers: if your AC still uses R-22, now is the time to plan for a replacement.

Is R-22 Refrigerant Illegal?

No, it’s not illegal to own or use a system with R-22. However:

You can’t refill it with new R-22
Only recycled or reclaimed R-22 is allowed—and it’s expensive
Many HVAC contractors are moving away from servicing R-22 systems

Eventually, repairing your system won’t be practical—or even possible.

How to Tell if Your AC Uses R-22

Not sure if your air conditioner uses R-22? Here’s how you can check:

Look at the manufacturer label on your outdoor unit.
Search for phrases like “R-22”, “HCFC-22”, or “Freon.”
If your system was installed before 2010, it likely uses R-22.

Still not sure? Schedule a visit with our certified HVAC technicians. We’ll inspect your unit and give you honest advice.

What Are the Alternatives to R-22?

Most new systems today use R-410A, an environmentally safer refrigerant. It’s more energy-efficient and widely supported by modern AC systems.

Other R-22 replacements include:

R-407C
R-134A
R-438A (also called MO99)

Each has pros and cons, but none are simple drop-in options. You need a professional HVAC contractor to retrofit or replace the system properly.

Should I Replace My R-22 AC System?

In most cases, yes. Here’s why replacing your R-22 system makes sense:

1. Save on Long-Term Costs

While installing a new unit might feel expensive, continuing to repair an R-22 system will cost more in the long run.

2. Boost Energy Efficiency

Newer AC models use up to 30–50% less energy. That means lower energy bills and a smaller carbon footprint.

3. Increase Home Comfort

Modern systems cool faster, run quieter, and offer smart thermostat compatibility for better temperature control.

4. Peace of Mind

Say goodbye to surprise breakdowns and limited parts availability.

What Happens If You Don’t Replace R-22?

If you stick with R-22 too long, you’ll eventually face:

Sky-high repair costs
Long wait times for parts
Limited technician availability
Reduced home resale value
Risk of total system failure during peak summer

A breakdown in July isn’t fun—especially in Texas heat. Replacing now prevents major stress later.
