One of the hottest discussions (pardon the pun) within the air conditioning and heating industry is the difference between two refrigerants – R-22 and R-410A. As a homeowner considering a purchase, it’s important that you understand the difference so you can make the best decision for your system. We’ve outlined below the main differences and why they matter.
HVACR service technicians find themselves at the forefront of the refrigerant transition in AC and commercial refrigeration. As hydrofluorocarbon (HFC) refrigerants with high-global warming potential (GWP) are being phased down, mildly flammable A2L refrigerants have been identified as potential lower-GWP alternatives. But information about A2L servicing requirements is largely unknown in the U.S., which raises many questions within the technician community. If you’re an HVACR technician, the chances of soon encountering A2Ls is very likely. It’s important to gain a better understanding of A2Ls to maximize safety and assist your customers with installation and service calls.
As a contractor, it is important that you are aware of the different federal minimum efficiency levels and compliance requirements across regions. Understanding the new standards and metrics (SEER2, EER2, HSPF2) will help both you and your clients feel confident moving forward with these changes.
The purpose of the American Innovation and Manufacturing (AIM) Act is to phase down HFC, or hydrofluorocarbons, production and consumption by 85% over the next 15 years, and support a transition to more environmentally and consumer-friendly cooling technology options. HFCs will continue to be available for existing equipment, but the EPA will establish requirements for managing any existing HFC in use.
With the transition to lower GWP refrigerants, you may wonder what this means for both your existing systems and for systems purchased ahead of the transition. We’ve outlined a few of the main differences between refrigerants along with some additional guidance on why selecting the correct refrigerant for the desired application matters.
In this episode, Lindsay, Jennifer, and Rajan continue the discussion from the previous episode, and further explore the world of system efficiency. Rajan explains the metrics (SEER, IEER, EER) used to rate AC systems and what it fails to cover.

In this episode, we will be going through the EPA’s SNAP Rules, what they mean and how they affect the industry, specifically technicians. We also discuss the history of these SNAP rules and the effects that they have on HFCs.

Today we answer the question, “Why are HFC’s not a good permanent solution?” We also discuss the greenhouse effects and how ozone-depleting gasses such as HFC’s are related to this. In addition, we explore the proliferation of refrigeration around the globe and the Kigali phase down and how it works.
