HVAC Refrigerant and Seer Changes in 2023

HVAC refrigerant and seer changes in 2023 as we explain in the blog of the upcoming changes you need to know.

A new year always brings change, and the HVAC industry is no exception to that rule.

Whether you have a resolution to improve the comfort of your home, increase your home’s energy efficiency, or plan to live hassle/worry free, pay special close attention to the upcoming changes. Some of these changes are bound to help you meet your goals and possibly save you some money in the long run.


The change from R-410a refrigerant to R-454b refrigerant will take place later in 2023. Expect the change come mid-year. A change in refrigerant can be confusing so we wanted to share some questions we received from customers. Here is what we know about HVAC refrigerant:

HVAC Refrigerant and Seer Changes in 2023

What is R-410a refrigerant?

This refrigerant is a hydroflurocarbon (HFC) commonly called Puron. This refrigerant has a high global warming potential that can contribute to climate change. It replaced R-22 or “Freon” about 20 years ago. 

What is R-454b refrigerant?

It is a more environmentally friendly alternative to R-410a. The industry change will create much lower global warming potential. R-454b will work very similar to previous refrigerants, however homeowners can expect better efficiency from the new refrigerant than what R-410a or R-22 had offered previously. 

Why is R-410a being phased out?

On December 27, 2020, the United States Congress passed the American Innovation Act, which directs the EPA to phase down production and consumption of hydroflurocarbons (HFCs). R-410a is not good for the environment so the change to R-454b should help lessen the carbon footprint of HVAC systems


Effective January 1, 2023 there will be new minimum efficiency standards dictated by the Department of Energy. What was known as SEER (seasonal energy efficiency ratio) will now be know as SEER2. The change takes place through a new government requirement for stricter efficiency testing. This new standard is known as the M1 Standard. New metrics are now being used to measure the energy performance of heat pumps and air conditioners.

You will notice air conditioner model numbers as well as heat pump model numbers adjust to reflect the transitions being made within the industry. A&G Heating & Cooling Co LLC along with Trane is committed to staying compliant with these new rules and will support homeowners throughout the change.

How do I know what type of refrigerant my air conditioner uses?

Your air conditioner user’s guide/manual will offer much information about your system refrigerant. You can also call your HVAC installation company to ask them for guidance. However, it’s best when working with air conditioner refrigerant you call a trusted professional to handle refrigerant line repair, adding refrigerant to the system, or general ac maintenance

What is the new HVAC refrigerant type in 2023?

R-454b is a more environmentally friendly alternative to R-410a. The industry change will create much lower global warming potential. R-454b will work very similar to previous refrigerants, however homeowners can expect better efficiency from the new refrigerant than what R-410a or R-22 previously offered. 

How do I know if my air conditioner or heat pump needs more refrigerant? 

There could be several reasons why your air conditioner or heat pump has stopped working. It may be low on refrigerant. This could be due to a leak in the coil. Coil leaks can sometimes occur when brazed joints become fractured or broken due to the expansion and contraction of the metal. If a leak is detected, a service technician will be able to guide you through the repair process which likely will include professionally repairing the leak and adding refrigerant to the line. 

Is R-22 or R-410a expensive?

As R-22 and R-410a are phased out due to federal government regulations, it becomes difficult for heating and air conditioning companies to acquire these refrigerants. That typically increases the cost due to lack of availability. Homeowners are encouraged to weigh the pros and cons of repair vs. replacement if they encounter loss of refrigerant within the heat pump or air conditioner
