When it comes to keeping your New England home cool and comfortable, Heritage Home Service knows that what’s inside your air conditioning system matters just as much as the system itself. One key component often overlooked is the refrigerant — the chemical that absorbs and releases heat to make cooling possible.
In recent years, new eco-friendly refrigerants have become the standard for HVAC systems. Understanding these changes isn’t just good for the environment — it can also help you save money, stay compliant with new regulations, and make smarter HVAC upgrade decisions.
Why Refrigerants Are Changing
Older refrigerants like R-22 (Freon) were once standard in home cooling systems across Massachusetts, New Hampshire, and Maine. However, R-22 has been phased out due to its ozone-depleting properties. As of 2020, it can no longer be produced or imported in the U.S., and servicing older systems has become more expensive and less practical.
The industry has since shifted toward greener alternatives that are safer for the environment and more energy efficient. These new refrigerants are part of a larger nationwide effort to reduce greenhouse gas emissions and modernize HVAC technology.
Meet the New Generation of Eco-Friendly Refrigerants
Here are the most common refrigerants you’ll see in new and replacement HVAC systems today:
R-410A
- Replaced R-22 as the standard refrigerant in most residential systems over the past decade.
- Does not deplete the ozone layer.
- Offers improved energy efficiency and better overall performance.
However, R-410A is now being gradually phased down due to its global warming potential (GWP), paving the way for even newer options.
R-3
- Considered a next-generation refrigerant.
- Has a significantly lower GWP than R-410A (about 68% lower).
- Uses less refrigerant volume to achieve the same cooling effect, which improves efficiency.
- Already widely used in Europe and Asia, and becoming more common in North American systems.
R-454B
- One of the leading replacements for R-410A in many modern heat pumps and air conditioners.
- Lower environmental impact, with a GWP about 78% lower than R-410A.
- Compatible with many existing system designs, making it a strong choice for future installations.
Why Homeowners Should Care
You might not think much about refrigerant when you adjust your thermostat — but these changes affect your home comfort, energy bills, and long-term costs.
Here’s why it matters:
- Regulatory Compliance: Older systems using R-22 can’t be recharged with new supply, and repairs can be costly due to dwindling availability.
- Energy Efficiency: New refrigerants often work with advanced system designs that use less energy, helping lower your monthly bills.
- Environmental Responsibility: Choosing eco-friendly refrigerants means reducing your home’s carbon footprint, contributing to cleaner air for New England communities.
- Future-Proofing: Installing a system that uses the latest refrigerants ensures you won’t face sudden changes in availability or new regulatory hurdles down the road.
What This Means for Your HVAC System
If your air conditioning system was installed before 2010, it may still use R-22. In that case, upgrading to a modern system is usually the smartest long-term investment. Systems that use R-410A, R-32, or R-454B offer:
- Quieter operation
- Better temperature control during hot New England summers
- Higher SEER ratings, which translate into energy savings
- Eligibility for Mass Save® and other rebates when replacing older, inefficient units
At Heritage Home Service, our licensed HVAC technicians can evaluate your current system, explain your refrigerant options, and help you choose an upgrade that balances comfort, cost, and environmental impact.
Rebates and Incentives for Eco-Friendly Upgrades
Many Massachusetts, New Hampshire, and Maine homeowners qualify for significant rebates when they upgrade to modern, high-efficiency HVAC systems that use eco-friendly refrigerants.
- Mass Save® Rebates: Offer substantial savings on qualifying AC and heat pump installations.
- State Energy Programs: Local utilities in NH and ME often provide additional rebates or low-interest financing for efficiency improvements.
- Federal Tax Credits: Certain ENERGY STAR® certified systems qualify for tax incentives under the Inflation Reduction Act.
Our team can guide you through the paperwork to make sure you maximize your savings while upgrading your home comfort system.
