Refrigerant is one of the most essential components in powering your HVAC machine. They make our home a whole lot more comfortable and our factories conducive to preserving functional temperatures for products. On the other hand, they pose negative impacts on the environment.
These changes will alter how you maintain or replace your system, so that it stays legal and easier on the environment. Knowing the details will help you plan the right upgrades for your home. So, without further ado, let’s dive in.
EPA Refrigerant Regulations 101
The Environmental Protection Agency has recently come out with new rules under the Clean Air Act and the AIM Act of 2020. They aim to phase out certain refrigerants in home heating and cooling systems, intended to cut ozone damage and emissions. Such arrangements are forged based on international agreements, such as the Montreal Protocol and its Kigali Amendment. This revolves first and foremost around cutting back on the HFCs & HCFCs.
Homeowners will be noticing changes when they service or replace their HVAC systems. Refrigerants move heat in and out of your HVAC, making your place cool in summer and warm in winter. Older chemicals like CFCs and HCFCs eat away at the ozone layer. Newer ones, HFCs, don’t hurt ozone but trap a lot of heat.
Their global warming potential, or GWP, shows how much they warm the world compared to CO₂. Some, like R-410A, score above 2,000. That number worries scientists. Over time, dropping these gases will help ease climate change and better protect the air we breathe.
Phase-Out of R-22: Implications for Homeowners
R-22, also called HCFC-22, used to be the go-to coolant for home air conditioners. The EPA stopped making or importing it after January 1, 2020. Still, you can get recycled R-22 to fix your existing unit with professionals from an AC repair studio city.
Here are the implications, as far as homeowners with R-22 systems are concerned:
- Legality: You can keep using your existing R-22 system, as there is no EPA requirement to replace it.
- Servicing challenges: R-22 supply comes only from reclaimed sources. Over time, this can drive up repair costs as supplies dwindle.
- Maintenance: Keep your system in good shape so that it runs longer and harms the environment less. Have EPA Section 608-certified techs fix leaks instead of just topping off the refrigerant. Proper upkeep saves money and protects the planet.
If your system is older or needs a lot of fixes, a new unit could save money in the long run. New air conditioners use better refrigerants. They cost less to run, and you might qualify for tax credits. Upgrading makes sense, especially as R-22 gets scarcer and service bills continue to mount.

Phase-Down of R-410A: Timeline and Impact
R-410A is a common refrigerant in newer HVAC systems. Its global warming potential (GWP) is a whole 2,088. It took over from R-22, but now it’s being phased down because of its environmental impact. Under the AIM Act, starting January 1, 2025, new air conditioners must stick to a GWP of 750 or less. Here’s what that means:
Manufacturing Deadline
Under the American Innovation and Manufacturing Act, every home or small‐business air conditioner and heat pump built after January 1, 2025, must use a refrigerant with a global-warming potential of below 700.
Most makers are choosing R-32 (GWP 675) or R-454B (GWP 466), both mildly flammable A2L refrigerants, to cut down on emissions. Production of higher-GWP blends like R-410A stops on that date, although units made before then can still be installed until January 1, 2026.
Installation Grace Period
Equipment built before January 1, 2025, can still be installed until January 1, 2026. This gives a one-year window so installers have time to work through existing stock.
For homeowners, here’s what to expect.
- Existing systems: If your system runs on R-410A, you can keep using it and get it serviced as usual. R-410A will stay on the market for servicing older units, so there’s no rush to change right now.
- New systems: After January 1, 2025, any replacement system will need a newer refrigerant. That might cost more up front, but it’s better for the planet over time.
Alternative Refrigerants: Safety and Efficiency
R-32 and R-454B have stepped in to replace R-410A. They carry an A2L rating and are mildly flammable. Still, they’re safe when used in systems built just for them, since new safety rules and building codes guide each step so that installation stays solid.
Because these systems follow precise guidelines, technicians prevent any hazards and keep everything reliable. And their impact on the climate is much lower, making them a greener choice.
| Refrigerant | GWP Value | Classification | Notes |
| R-22 | 1,810 | HCFC | Phased out since 2020, ozone-depleting. |
| R-410A | 2,088 | HFC | Being phased down, high environmental impact. |
| R-32 | 675 | A2L | Lower GWP, used in new systems, is efficient. |
| R-454B | 466 | A2L | Lowest GWP among alternatives, safe for new designs. |
These refrigerants run more efficiently so that your energy use goes down and your bills shrink over time. They’re easier to reclaim, to keep the environment cleaner.
Costs and Financial Perks
Switching to new refrigerants can bump up the price of HVAC units. Makers say EPA‑friendly models may cost at least 20% more, since they need parts built for A2L refrigerants and a few extra tweaks. On top of that, new building rules like adding fire‑rated shafts for refrigerant lines just add to the install bill.
Still, there are ways to ease the pinch. A federal tax break lets you claim up to $2,000 for an energy‑smart HVAC install, like an HVAC.Repair heat pump, under the Inflation Reduction Act. No income test applies, just your main home.
New systems often use less power. You could pocket about $160 a year in energy savings, which helps pay back that first spend over time, so that it stings less.
Don’t forget to tap into state or local rebates. They change by area and can put more money back in your pocket.
If you’re still running an old R‑22 unit, get ready for service costs to climb once supplies dry up. Regular upkeep and keeping leaks at bay become key moves to dodge frequent fixes.
Practical Tips
When considering a new HVAC system, homeowners should:
- Do their homework and pick models that meet EPA rules, using safer refrigerants like R-32 or R-454B, and are built to save energy.
- Team up with an EPA-certified HVAC pro who knows the 2025 rules inside out. They’ll point you to the right system for your space and wallet, so that you stay within code and get top performance.
- Keep the January 1, 2026, deadline in mind for installing units made before 2025. Planning ahead means you won’t have to rush at the last minute.
- Hunt down any tax credits or rebates – federal, state, or local – to help ease the cost. The IRS lists programs you might qualify for, so you don’t miss out.
- Stay on top of regular tune-ups to keep your system running longer and greener. Ask EPA-certified techs to fix leaks and spots of wear, to protect your wallet.
