Rising energy bills, hot spots around the house, or an HVAC system that can’t keep up—these are signs it might be time to replace your system. As HVAC units age (especially after 10–15 years), they lose efficiency and cost more to run. If your system is unreliable, inconsistent, or always breaking down, it won’t be able to handle the heat—literally. With another sweltering Minnesota summer on the way, replacing your HVAC system could be the long-term solution your home needs.
But here’s the twist: 2025 brought major changes to the HVAC world. Manufacturers are moving away from the standard R-410A refrigerant to newer, low-emission A2L refrigerants. This means homeowners are dealing with new technology, shifting regulations, and unfamiliar options. The good news? Pre-2025 HVAC systems using
R-410A are still available, reliable, and more budget-friendly.
This guide covers what’s changing with HVAC refrigerants, why pre-2025 systems are still a great HVAC option, and how to plan for the future. Keep reading to find out what you need to know to make the best decision for your home!
What Changed with HVAC Refrigerants in 2025?
Let’s start with what changed in 2025—and why R-410A systems are still a solid option.
What is R-410A refrigerant?
R-410A is a refrigerant (a fluid that absorbs and releases heat) found in many modern air conditioners, HVAC systems, and heat pumps. It once replaced the older R-22 refrigerant because it was more ozone-friendly. R-410A has powered reliable, energy- efficient cooling to well over a million Minnesota households over the past two decades, based on U.S. Census data and residential energy use trends from the U.S. Energy Information Administration.
Why is R-410A Being Discontinued?
The Environmental Protection Agency (EPA) recently passed the American Innovation and Manufacturing (AIM) Act, which aims to gradually reduce the use of hydrofluorocarbons (HFCs)—including R410A. The goal? Lower the refrigerant’s global warming potential (GWP) and encourage adoption of new eco-friendly alternatives.
This AIM Act includes the following key changes:
- New Equipment Restrictions: As of 2025, HVAC manufacturers can no longer produce new equipment designed for R-410A.
- Continued Service Availability: There is no immediate ban on using or servicing existing R-410A systems.
- Ongoing Support for R-410A Systems: If you install a pre-2025 HVAC system that uses R-410A refrigerant today, you can expect many years of continued performance and full support for maintenance, repair, and R-410A refrigerant recharges.
Will R-410A Refrigerant Disappear Anytime Soon?
Not at all. R-410A will remain available for many years after 2025. Even though manufacturers are now producing systems with newer refrigerants, R-410A will still be produced, sold, and circulated until likely into the 2040s with reclaimed and recycled refrigerant possibly extending the supply.
That means if you’re thinking about installing a pre-2025 system that uses R-410A, you’ll still have access to the refrigerant, service, and repairs for the long-term. Pre-2025 systems are a reliable, familiar option that technicians know well—and it won’t leave you in the lurch down the line.
Key takeaway for Minnesota homeowners: If you already own an R-410A HVAC system, or you’re thinking of installing one, you’re not getting left behind. These systems will remain serviceable, reliable, and safe for a long time.
Why a Pre-2025 System Still Makes Sense in Minnesota
Even with the phaseout coming, there are plenty of reasons why an R-410A system is
still a good investment for your home.
The newest systems on the market always tend to cost more, and many homeowners are noticing the higher price tags on the new 2025 HVAC models. That’s why many homeowners are still choosing pre-2025 systems that use R-410A. These models are often more affordable up front and still easy to maintain.
Here’s a look at both options—and what they could mean for your budget:
Pre-2025 HVAC Systems with R-410A Refrigerant
- Lower Upfront Price: Pre-2025 systems often cost less than the newest models—sometimes saving homeowners hundreds or even thousands of dollars.
- Extra Deals Right Now: Many suppliers are discounting these systems to make room for newer inventory, which can mean even bigger savings.
- Easy to Repair and Maintain: These systems use parts and refrigerant that are still widely available—and technicians are already experienced working with them. Since the EPA still allows the sale of equipment made before 2025, service and support remain straightforward.
2025 HVAC Systems with A2L Refrigerants
New systems made in 2025 will use A2L refrigerants, such as R-32 and R-454B. These A2L refrigerants are more eco-friendly, but they also come with a higher price—often up to 10–30% more for a full system and installation.
Here’s why:
- New Design and Safety Requirements: These systems need new parts and extra safety features, which makes them more expensive to build and install.
- Repair and Service Costs: Technicians need special training to work with A2L refrigerants, which could mean higher costs for service.
- Tariffs on Materials: New tariffs on imported HVAC parts are already driving up prices—especially for systems that use A2L refrigerants. According to ACHR News, one major supplier raised the price of R-454B by 15% in February, added another 8% in March, and then tacked on a 42% surcharge in April to prepare for anticipated tariffs.
Why R-410A Support and Maintenance Will Remain Strong
Even with the refrigerant transition underway, there’s no need to worry about keeping a pre-2025 HVAC system up and running. R-410A will remain available for servicing, and most technicians are already experienced with these systems—making ongoing maintenance, repairs, and refrigerant recharges straightforward for years to come.
The EPA planned for a long transition period so homeowners wouldn’t be left in the cold (literally). These pre-2025 HVAC systems are still going strong, especially here in Minnesota, where they’ve proven their reliability year after year. From long-lasting parts and refrigerant access to local experts who know these systems inside and out, support isn’t just available—it’s solid.
Proven Reliability in Minnesota’s Unique Climate
- Durability in Harsh Winters: Minnesota’s extreme weather demands dependable systems. R-410A systems are built for durability, performing well through freezing winters and humid summers.
- Local Expertise: Minnesota HVAC contractors are well-versed in R-410A systems, ensuring top-notch installation and service, backed by decades of proven reliability.
Wide Compatibility
- Ongoing Availability: R-410A parts and refrigerant will remain accessible well into the future. Most Minnesota HVAC companies are stocked up and prepared for ongoing service.
- Warranty Protection: Pre-2025 R-410A systems still benefit from manufacturer and service warranties, offering peace of mind for years to come.
With these pre-2025 HVAC systems, you’re not facing a use-it-and-lose-it situation; you’ll get years of reliable performance with these systems.
Who Benefits Most from Pre-2025 HVAC Systems?
These systems are especially great for:
- Homeowners Replacing Older Systems: If your current unit struggles to perform, upgrading now helps avoid unexpected breakdowns during extreme weather.
- Anyone Looking for Lower Upfront Costs: These systems are ready to install now—and often come with discounts that make them easier on the budget. A pre-2025 unit offers reliable comfort without the higher price tag of newer models.
- Households Wanting Proven Performance in a Variable Climate: Pre-2025 HVAC systems have a solid track record in both Minnesota summers and winters, delivering steady cooling and heat when it’s needed most.
Common Questions about the R-410A Phaseout in Minnesota
Here’s a quick recap of what we’ve covered so far—plus answers to the questions many
Minnesota homeowners are still asking:
- Will parts and refrigerant for my R-410A system be discontinued right away?: R-410A will still be available for service and repairs. There’s already a large supply in circulation, and support will continue.
- Will I be forced to replace my current system in order to comply with the new guidelines?: No. There’s no rule requiring replacement. If your system is working well, you’re not expected to upgrade.
- Should I upgrade anyway to a next-generation system?: That depends on your system’s age and condition. Nearing 12–15 years? It might be time to look into newer options. Still working well? No need to rush.
- Are pre-2025 R-410A systems safe and up to code?: Yes. R-410A systems remain fully compliant and safe to use, even as newer refrigerants begin to roll out.
Tips for Minnesota Homeowners Considering a Pre- 2025 HVAC System
Replacing or repairing an HVAC system is a big investment. The R-410A refrigerant phaseout doesn’t mean Minnesota homeowners need to panic or overspend. Instead, it’s an opportunity for smart decision-making and long-term planning.
When making the decision on your next HVAC system, plan on doing the following:
Anticipate Your Needs: Choose what works for your home and budget right now. Pre-2025 HVAC systems remain one of the most reliable and well-supported options in Minnesota.
Monitor Your Current System: Monitor the efficiency and performance of your current HVAC system. If you notice a spike in utility bills or reduced performance (like uneven cooling or strange noises), don’t wait to call for service. Catching issues early saves money and hassle.
Schedule Regular Maintenance: Keeping your HVAC system maintained extends its lifespan and reduces the chance of emergency repairs. Annual tune-ups, filter changes, and inspections can keep your pre-2025 HVAC system running smoothly for years.
