2023 HVAC Regulations

How will new 2023 HVAC regulations impact your home?

The HVAC industry is set to make big changes in 2023 with new regulations to increase energy efficiency and eco-friendliness. The new regulations will impact you as a homeowner and your current HVAC units, so it’s important to understand what to expect.

This guide will provide an overview of the 2023 HVAC regulations, including changes to the seasonal energy efficiency ratio (SEER) and refrigerant requirements. We will also discuss the benefits and potential drawbacks of the new regulations and answer questions about upgrading your old HVAC system.

SEER Regulations

SEER stands for Seasonal Energy Efficiency Ratio, which measures the cooling output of an air conditioner compared to the electrical energy it consumes. The higher the SEER rating, the more efficient the AC.

Starting January 1, 2023, two changes will be related to SEER regulations. First, the minimum SEER rating will increase for HVAC equipment. Currently, new air conditioners must have a minimum SEER rating of 13 in northern states and 14 in southern states. This will change to 14 and 15, respectively, in 2023.

Additionally, the industry will adopt the SEER 2 standard. SEER 2 measures the total heat removed from a specific space versus the energy used in the process. The required testing conditions will change to reflect real-life circumstances better. In 2023, HVAC equipment, including AC condensers and heat pumps, will have to display their SEER 2 rating on their packaging.

These changes will give consumers a better estimate of their potential energy usage when shopping for new HVAC equipment, but they will only impact homeowners beyond that. With the increased focus on energy efficiency, it’s important to consider these changes when purchasing or repairing an HVAC system in 2023.

Refrigerant Regulations

Recently, the HVAC industry moved from R-22 (Freon) refrigerant to R-410 (Puron) refrigerant due to its reduced harm to the environment and human health and its ozone-friendly properties. Now, the industry is preparing for another change as the Environmental Protection Agency (EPA) is likely to require using another class of refrigerants called A2L by 2025.

A2L refrigerants have a lower Global Warming Potential (GWP) than alternatives, but they are also mildly flammable. As a result, HVAC manufacturers are developing new technology to accommodate the use of A2L refrigerants, such as new storage and transportation systems and equipment with automatic shutoff capabilities in case of a leak.

This shift in refrigerants aims to reduce the carbon footprint of HVAC systems and promote a more sustainable and eco-friendly industry. It might not immediately impact homeowners, but it’s vital to be aware of these upcoming changes and their potential environmental benefits.

Pros and Cons of New HVAC Regulations

As with any major change, there are pros and cons to the new HVAC regulations taking effect in 2023. While the overall impact of these regulations is positive, it’s important to understand the potential consequences as well.


  • Positive Environmental Impact: Most HVAC equipment requires significant energy to operate, contributing to carbon dioxide emissions and global warming. The new regulations push for more energy-efficient and eco-friendly products, reducing the industry’s carbon footprint.
  • Reduced Utility Bills: The increased energy efficiency of new HVAC equipment means that homeowners can expect to see a reduction in their utility bills.


  • Difficulty in Finding Replacement Parts: As the industry phases out older technologies, finding compatible parts for older HVAC systems may become harder, making repairs more challenging.
  • Initial Inventory Challenges: The industry may experience challenges in obtaining inventory that meets the new regulations, which could lead to longer wait times for parts or replacement units.

It’s important to note that the new HVAC regulations are a positive step towards a more sustainable and energy-efficient future. While the 2023 HVAC regulations may create minor inconveniences, such as longer wait times for replacement parts or initial inventory challenges, upgrading to a new HVAC system is still important, and the benefits of a more energy-efficient and eco-friendly system far outweigh the drawbacks.

By reducing your carbon footprint and lowering your utility bills, you can positively impact the environment while saving money in the long run. And with technology constantly evolving and the phase-out of older systems, upgrading to a new HVAC system will ensure your home stays comfortable and up-to-date with the latest industry standards.

How to Upgrade Your HVAC System

The new 2023 HVAC regulations, including the increased SEER ratings and the switch to eco-friendly refrigerants, will result in HVAC systems that are better for the environment and more energy-efficient.

Upgrading your HVAC system to meet these new 2023 regulations can seem overwhelming, but it’s an important step towards a more sustainable and energy-efficient future. Here are a few tips on how to make the process smoother and easier:

Assess Your Current System

Before you upgrade, assess the current state of your HVAC system and consider its age, efficiency, and overall condition. If it’s in good working order, you might not need to replace it entirely.

However, if your HVAC system is old, outdated, and frequently requires repairs, upgrading to a new one, or scheduling a repair, is likely your best option. To determine the current state of your HVAC system, consider having it inspected by a professional.
