Increasing Cost of AC Units Due To Refrigerant Changes
The cost of new air conditioning units is on the rise in 2025. One of the biggest reasons is the industry-wide phase-out of R410a refrigerant. This commonly used refrigerant is being replaced by more environmentally friendly alternatives due to new federal regulations aimed at reducing harmful emissions.
For Florida homeowners, this shift means higher equipment prices, changes in installation standards, and long-term decisions that can affect your comfort and utility costs. As a Florida HVAC installer serving Zephyrhills and surrounding areas, Custom Air Conditioning & Air Quality is here to help you make sense of these changes and prepare for what’s ahead.
Why AC Unit Costs Are Rising?
In 2025, new EPA regulations under the AIM Act are phasing out the use of R410a refrigerant due to its high global warming potential. As a result, manufacturers are now required to produce air conditioning systems that use eco-friendlier refrigerants like R32 or R-454B.
This shift is causing a rise in AC unit costs across the board.
New refrigerants require redesigned components, updated safety features, and specialized training for technicians, all of which add to production and installation expenses.
Additionally, the supply chain is adapting to these changes, which means parts and systems are in higher demand and sometimes harder to source. Together, these factors are driving up the overall price of new HVAC systems in 2025.
What Is R410a and Why Is It Being Phased Out?
R410a is a widely used refrigerant found in most residential and commercial air conditioning systems installed over the past two decades.
While effective for cooling, it has a high Global Warming Potential (GWP) of 2,088, meaning it traps over 2,000 times more heat than carbon dioxide when released into the atmosphere.
Due to its environmental impact, the EPA is enforcing a nationwide phase-out under the American Innovation and Manufacturing (AIM) Act, which aligns with broader global climate goals aimed at reducing harmful hydrofluorocarbon (HFC) emissions and promoting more sustainable cooling solutions.
New Refrigerants: R32 and R-454B
With the phase-out of R410a, the HVAC industry is transitioning to newer, more environmentally friendly refrigerants, including R32 and R-454B.
Both options offer significantly lower Global Warming Potential (GWP) compared to R410a, helping reduce environmental impact. R32 has a GWP of 675, while R-454B is even lower at 466.
These refrigerants also deliver better energy efficiency, which translates to lower monthly utility bills and long-term cost savings for homeowners.
However, both are classified as A2L refrigerants, meaning they are mildly flammable and require specialized handling and installation. That’s why it’s critical to work with certified HVAC professionals like the team at Custom Air Conditioning & Air Quality to ensure safe, compliant service.
What This Means for Homeowners?
For homeowners, these refrigerant changes bring both challenges and opportunities.
New AC systems using R32 or R-454B are typically 10–15% more expensive upfront due to updated technology and installation requirements.
Meanwhile, repairing older R410a systems is becoming increasingly costly, as the refrigerant is no longer being produced and supplies are dwindling.
However, making the switch now can lead to long-term energy savings and improved system performance. If your air conditioner is more than 10 years old, it may be more economical to invest in a new, energy-efficient unit rather than continue paying for rising repair and refrigerant costs.
Upgrading now ensures compliance with regulations and avoids future headaches.
