HVAC Refrigerant and SEER Changes in 2025

Are you shopping for a new heating, ventilation, and air conditioning (HVAC) system in Purvis, MS, or the surrounding area?

If so, you will want to read this first.

The U.S. Department of Energy (DOE) raised the minimum efficiency requirements for central air conditioners and air-source heat pumps starting in 2023. All existing systems must meet these minimum standards.

Additionally, since 2023, the U.S. Environmental Protection Agency (EPA) has been phasing down the manufacture and importation of R-410a, a commonly used refrigerant for residential cooling systems. Starting in 2025, R-410a will no longer be allowed in the manufacturing of new HVAC systems.

The two changes will create a new generation of HVAC systems designed to be more efficient and eco-friendly. But you’ll also pay more to enjoy these new features, a factor to consider if you plan to replace your equipment in the next few months.

Bowman Heating & Air Conditioning is a trusted name for providing quality HVAC service to Purvis households and businesses. Give us a call for any questions you have about your next home improvement project!

What Is SEER and How Does it Impact HVAC Systems?

The seasonal energy efficiency ratio (SEER) measures cooling system efficiency. The higher the number, the better the efficiency.

SEER ratings for AC units and heat pumps have increased from 13 to 14 in northern states and 14 to 15 SEER in the South and Southwest regions of the country.

In terms of heating efficiency, air-source heat pumps have increased from 8.2 to 8.8 HSPF (heating seasonal performance factor).

The increase in efficiency means you will use less electricity for the same amount of cooling. Your Purvis home’s carbon footprint will shrink, and so will your utility bills. But you can expect manufacturers to increase prices to accommodate the new SEER ratings.

Is your cooling system more than eight years old and less than 15 SEER? Now is the perfect time to replace it. Why keep outdated, obsolete equipment that will drive up your electric bills? Call Bowman Heating & Air Conditioning today for a free consultation and upfront pricing.

What Is SEER2?

SEER2 represents new testing standards for cooling systems. The testing standards give consumers a more accurate picture of how an installed HVAC system will perform.

Similar to the changes in the SEER rating, these new testing standards do not impact your current system. The new testing requirements mean any equipment the manufacturers produce must now adhere to SEER2 standards.

New Refrigerants in 2025

Since 2010, residential cooling systems have contained a refrigerant called R-410a, a hydrofluorocarbon (HFC) that has high global warming potential and could harm the environment if it leaks from a cooling system.

For that reason, the U.S. Environmental Protection Agency (EPA) is phasing down the manufacture and importation of HFCs by 85 percent over the next decade.

Beginning next year, all new cooling systems will contain a refrigerant called R-454b, which has a lower global warming potential.

This refrigerant is more environment-friendly than its predecessors but also mildly flammable. You can rest assured our Bowman Heating & Air Conditioning technicians know how to handle it safely.

What If My Cooling System Uses R-410A?

Although R-410a will be available for equipment repairs over the next decade, no new air conditioners or heat pumps will contain R-410a beginning in 2025.

You do not have to replace any equipment because of the new refrigerant changes.

A well-maintained AC system will last 10 to 15 years. If you need a new unit, buy it this year. There should be enough R-410a to last the life of your system, but the cost of replacing the refrigerant might creep up eventually if you need a repair.

Can I Retrofit My AC to Use R-454B?

No. Refrigerants operate at different pressures. An R-410a air conditioning or heat pump system will not be calibrated to use R-454b.

Even if you could retrofit your equipment to handle different refrigerants, the cost of doing so would likely approach the price of a new system. Plus, you would more than likely void your existing warranty.

You can save money immediately on utility bills by upgrading today to a high-efficiency system. Plus, you’ll pay less in purchasing costs. Otherwise, wait until 2025 to buy a system with the new refrigerant and SEER ratings. Our trained professionals can walk you through the pros and cons.
