HVAC systems manufactured in 2025 and beyond will no longer use R-410A, the most common refrigerant in current residential air conditioning units and heat pumps. This is part of a global effort to reduce the environmental impact of refrigerants that contribute to global warming and ozone depletion.
Starting January 1, 2025, all new residential air conditioners and heat pumps must utilize A2L refrigerants. Older refrigerants like R-410, which are likely the refrigerant used by your current system, are being phased out. These new systems are designed to have a lower global warming potential (GWP).
Efficiency ratings are regional, so the new HVAC regulations for 2024 depend on where you live. New air conditioners in Northern regions must have a minimum SEER rating of 14. In Southern regions, the minimum SEER rating is 15 for most units.
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).
In absence of regulatory certainty at the federal level, many states have adopted environmental regulations that seek to limit the negative impacts of short-lived climate pollutants (SLCP) such as HFCs. California was the first state to take official action. California Senate Bill 1383, also known as the Super ...
The new refrigerant changes in 2025 are part of a larger effort to make air conditioning systems more environmentally friendly, while still keeping homes comfortable. These changes are being driven by regulations to phase out older refrigerants like R-410A, which have a high global warming potential (GWP).
If your system is nearing the end of its life, replacing it before 2025 could be a smart move to avoid higher prices later. Rising Repair Costs: If your system requires frequent repairs or uses R-22 refrigerant, which is already phased out, you might be better off replacing it now.
As a part of this plan, R-410A refrigerant will be gradually phased out of production. The objective is to replace it entirely with A2L refrigerants over time. Starting in 2025, HVAC manufacturers can no longer make equipment that requires R-410A.
The standards have to keep evolving as the technology does or else we'd be stuck in the figurative stone age with our heating and cooling solutions. That's why the United States Department of Energy or DOE has decided to discontinue production of air conditioners with a SEER rating of 14.
Repair: Older AC units typically have lower energy efficiency ratings (SEER), which means higher electricity costs. For instance, a 20-year-old unit may have a 10- or lower SEER.
R-454B. R-454B is the newest refrigerant, which will gradually replace R-410A, the refrigerant used in HVAC manufacturing from 2010 until the phase-out is complete in January 2025.
AC systems typically have a lifespan of 10 to 15 years. If your unit is approaching or has surpassed this age range, it might be time to consider a replacement. Older systems tend to be less reliable and more expensive to operate.
What SEER rating qualifies for tax credit 2024? Split ducted heat pumps and packaged heat pumps must meet a SEER2 rating of 15.2 or above. Non-ducted heat pumps must meet a SEER2 rating of 16 or above.
Heat Pumps are Eligible for Incentives in 2025
Heat pump rebates and tax credits are a big reason why heat pumps are worth it in California. There are several incentives for heat pump installation in California in 2025.
On January 1, 2020, the U.S. Environmental Protection Agency (EPA) banned the production and import of R-22. But units manufactured in 2009 and earlier still use R-22 today. Its use will eventually be eliminated in the U.S., so all current and future homeowners must be prepared for the transition.
How much does a new HVAC system cost for a 2,000 sq. ft. home? The costs range from $6,224 to $11,434, depending on the system type and installation requirements. Key factors include system size, type, efficiency, and local labor rates.
According to the Kobie SEER Energy Savings Calculator, a 16 SEER unit uses about 13% less energy to produce the same amount of cooling as a 14 SEER unit of the same size. That means that for every $100 you'd pay to run your 14 SEER unit, you could save $13 by upgrading to a 16 SEER unit.
Minimum SEER Ratings for 2024
Packaged AC: 15.2 SEER2 and 11.5 EER2. Ducted split heat pump: 15.2 SEER2, 7.8 HSPF2, and 11.7 EER2. Packaged heat pump: 15.2 SEER2, 7.2 HSPF2, and 10.6 EER2. Mini-split system: 16 SEER2, 9 HSPF2, and 12 EER2.
In general you should consider upgrading to a higher SEER if you live in a very hot climate and/or if you have a large home. The best way to see how much a higher SEER unit can save you is by checking an online SEER calculator.
If you replace your AC after the phaseout begins in January 2025, your costs could increase by as much as 30%. This is because it's more expensive for manufacturers to produce HVAC systems that use the new refrigerants.
ComStar's RS-53 (R470A) is the world's only drop-in retrofit replacement for existing R410a systems.
How much will an R-22 to R-410A conversion cost? The actual cost will depend on many things, including where you live, but most of the time R-22 conversions start at around $2,000 and go up from there. The higher end of that range is somewhere around $4,500 to $4,600.
On December 20, 2023, the EPA finalized and amended a rule that will allow one additional year (January 1, 2026) for the installation of new residential air conditioner and heat pump components manufactured or imported prior to January 1, 2025.
Big changes are coming to the HVAC industry starting January 1, 2025, due to new EPA regulations on refrigerants. These rules aim to reduce environmental impact but could significantly affect how consumers buy or repair HVAC units. The EPA will require refrigerants with a Global Warming Potential (GWP) below 700.
