Learn How Latitude .43 HVAC Can Help You With the 2025 Refrigerant Mandate

As a homeowner near Madison, WI, it’s essential to stay informed about significant changes impacting residential HVAC systems. With the upcoming 2025 refrigerant mandate, Latitude .43 HVAC is here to guide you through the transition smoothly. This blog post will explain the government mandate for HVAC systems, its impact on homeowners in the Madison area, and the ideal time to upgrade your system.

Understanding the Government HVAC Refrigerant Mandate

Starting January 1, 2025, the Environmental Protection Agency (EPA) will phase out the use of R-410A refrigerant in residential HVAC systems, replacing it with R-454B and R-32. This mandate aims to reduce global warming by requiring new systems to use refrigerants with a lower global warming potential (GWP).

What About Current HVAC Systems?

If you own an HVAC system using R-410A, service parts and refrigerants will still be available. However, as new R-410A systems become scarce, you’ll eventually need to transition to a system that operates with the new refrigerant.

Impact on Homeowners

As Latitude .43 HVAC transitions to new systems complying with the mandate, here’s how homeowners will be impacted, both positively and negatively.

Positive Impacts

  • Environmental Impact: Switching to refrigerants with lower GWP helps reduce the carbon footprint, contributing to a healthier planet.
  • Energy Efficiency: The new A2L refrigerants like R32 and R454B have a 78% lower GWP than previous refrigerants, benefiting both the environment and your wallet. Enhanced efficiency and better performance will reduce your monthly energy bills.
  • Future-Proofing: Purchasing a unit that complies with the latest regulations ensures long-term compliance and avoids costly retrofits or replacements.

Negative Impacts

  • Increased Costs: New HVAC systems could cost up to 30% more due to higher production costs associated with new designs, parts, and safety features.
  • Supply Chain Disruptions: Transitioning to new refrigerants and parts may cause availability issues, leading to delays and shortages.
  • Retrofit Challenges: Existing HVAC systems may need retrofitting to be compatible with new refrigerants, which can be expensive and technically challenging.
  • Training Requirements: HVAC technicians must undergo re-training to manage the installation and repair of new systems. Unprepared HVAC companies may face service delays, increased labor costs, and potential replacement issues.

What Homeowners Should Do

  1. Assess Your Current System: Determine the age and condition of your current HVAC system. If it is nearing the end of its lifespan, consider upgrading to a new system that uses A2L refrigerants.
  2. Consult with Professionals: Speak with HVAC professionals to understand the best options for your home. They can provide recommendations based on your specific needs and local climate conditions.
  3. Plan for Future Upgrades: If your current system is still in good condition, start planning for future upgrades. Budgeting for a new system can help mitigate the financial impact when the time comes.
  4. Regular Maintenance: Ensure your existing system is well-maintained to extend its lifespan and efficiency. Regular maintenance can also help identify any potential issues early.

Common Questions and Answers

Q: What happens if my current system uses R-410A?
A: Your existing R-410A system can continue to be serviced and maintained. However, when it comes time to replace the system, you will need to install a unit that uses an A2L refrigerant.

Q: Are A2L refrigerants safe?
A: Yes, A2L refrigerants are safe when handled properly. HVAC technicians are trained to work with these refrigerants, and systems are designed with safety in mind.

Q: Will I need to replace my entire HVAC system?
A: If you decide to switch to an A2L refrigerant, you will need to install a new system designed for that refrigerant. Existing R-410A systems cannot be retrofitted for A2L refrigerants.

Q: How much more efficient are A2L systems?
A: A2L systems are generally more efficient, leading to lower energy consumption and utility bills. The exact efficiency gains will depend on the specific system and installation.

Q: What should I consider when choosing a new HVAC system?
A: Consider the size of your home, local climate conditions, energy efficiency ratings, and long-term costs. Consulting with an HVAC professional can help you make the best choice for your needs.


The transition from R-410A to A2L refrigerants and the new 2023 efficiency standards represent a significant shift in the HVAC industry. These changes aim to reduce environmental impact, improve energy efficiency, and ensure compliance with new regulations. Homeowners need to stay informed about these developments to make the best decisions for their home comfort and energy use.
