- Bellows Plumbing, Heating, Cooling, & Electrical Guides the Transition: Expert support for installation, rebates, and long-term savings.
Understanding Global Warming Potential in HVAC Systems
Global Warming Potential represents how much heat a greenhouse gas traps in the atmosphere compared to carbon dioxide (CO₂).
When we talk about GWP in HVAC systems, we’re measuring how much impact different refrigerants have on global warming over time, typically measured over a 100-year period.
Carbon dioxide serves as the baseline measurement, with a GWP of 1. This means that refrigerants with higher GWP values have a proportionally greater impact on global warming. For instance, a refrigerant with a GWP of 2,088 has 2,088 times more warming impact than the same amount of CO₂.
Global Warming Potential Ratings: Comparing Common HVAC Refrigerants
The HVAC industry has undergone several transitions in refrigerant types, each driven by environmental concerns. Understanding these changes helps homeowners make informed decisions about their HVAC systems.
Let’s break down the three main refrigerants and their environmental impact:
1. R-22 (Freon)
This older refrigerant, with a Global Warming Potential of approximately 1,810, has already been phased out. While it cooled homes effectively for decades, its ozone-depleting properties led to its ban. If your home still uses R-22, replacement options should be considered as this refrigerant becomes increasingly scarce and expensive.
2. R-410A (Puron)
Currently the most common refrigerant in residential systems, R-410A has an even higher GWP of 2,088. While it doesn’t damage the ozone layer, its significant contribution to global warming has led to its scheduled phase-out beginning in 2025. Many homeowners currently have systems using this refrigerant.
3. R-454B
This is the industry’s newest solution, with a dramatically lower GWP of 466. It represents a significant step forward in environmental protection while maintaining efficient cooling performance. Most new systems are being designed to use this more eco-friendly option, making it the current gold standard for residential HVAC installations.
Low Global Warming Potential: The Future of HVAC Refrigerants
The transition to low-Global Warming Potential refrigerants isn’t just an environmental choice – it’s becoming a regulatory requirement. The EPA and international agreements are driving this change to combat climate change effectively.
Under the American Innovation and Manufacturing (AIM) Act, the phase-down of high-GWP refrigerants begins in 2025, with a goal of reducing HFC production and consumption by 85% over the next 15 years.
This regulatory shift brings significant changes to HVAC technology and installation requirements:
Safety and Installation Changes
New low-GWP systems require advanced safety features, including mandatory leak detection systems and updated ventilation requirements.
These systems are designed with sophisticated sensors and automatic shutoff mechanisms to ensure safe operation. While these features add to the initial cost, they provide enhanced safety and peace of mind for homeowners.
Technology Advancements
Modern low-Global Warming Potential systems incorporate cutting-edge technology to maintain optimal performance while reducing environmental impact. These advancements include:
- Variable-speed compressors for improved efficiency
- Smart monitoring systems for optimal operation
- Enhanced heat exchange technology for better performance
Cost Considerations
While these changes may increase initial system costs by 20-30%, they often provide better long-term value through:
- Reduced energy consumption and lower utility bills
- Decreased maintenance needs due to improved system design
- Protection against future refrigerant price increases
- Potential eligibility for environmental incentives and rebates
Our team helps customers navigate these changes by providing detailed cost-benefit analyses and explaining how these new systems can actually save money over time.
Our technicians are specially trained in low-GWP system installation and maintenance, ensuring your investment is properly protected while meeting all current and upcoming regulatory requirements.
Global Warming Potential Impact on Homeowners
If you currently have an R-410A system, you’re facing some important decisions. While R-410A systems can still receive repairs, the refrigerant will become increasingly expensive as supplies dwindle.
This situation mirrors what happened with R-22, where costs skyrocketed during its phase-out. For those considering a new HVAC system, understanding GWP becomes crucial for making a smart investment.
New R-454B systems, while potentially more expensive upfront, offer several advantages:
- Better long-term cost efficiency through improved system performance
- Future-proof compliance with environmental regulations
- Reduced environmental impact through lower GWP ratings
- Enhanced safety features including required refrigerant detection systems

Making the Transition to Low Global Warming Potential Systems
When considering the switch to a low-GWP system, timing is crucial. While your existing R-410A system may continue functioning, planning ahead for the transition can help you avoid emergency replacements and take advantage of current incentives and rebates.
Most homeowners find themselves in one of three situations:
If your system is less than 5 years old: Your R-410A system still has significant life left. Focus on proper maintenance to extend its lifespan while planning ahead for an eventual upgrade. This gives you time to budget for a future low-GWP system while maximizing your current investment.
If your system is 5-10 years old: This is the ideal planning window. Start discussing options with our team to develop a strategic replacement timeline. Current rebates and incentives can make an early transition more affordable, potentially saving you money before R-410A prices surge during the phase-out.
If your system is over 10 years old: Consider making the switch sooner rather than later. Older systems are less efficient and more prone to breakdowns. Transitioning now can help you avoid emergency replacements while taking advantage of current pricing before industry-wide changes impact costs.
