The passing of the American Innovation & Manufacturing (AIM) Act in 2020 has initiated a gradual phase-down of hydrofluorocarbon (HFC) refrigerants, with an 85% reduction from baseline targeted by 2036. The EPA has proposed restrictions on HFCs in new appliances with compliance dates as early as 2025, leading to the selection of mildly flammable refrigerants as replacements. Copeland has surveyed contractors and wholesalers on their preparedness for these new requirements and is dedicated to educating customers and providing solutions to accommodate the changing refrigerant regulations.
As policies and regulations change, a transition is being made toward low global warming refrigerants and new codes. Here we will discuss ASHRAE 34 and 15, as well as the adoption of new codes and standards and how they can vary from state to state.
Previously we have looked at federal minimum energy efficiency levels and the metrics used today to rate air conditioning systems (such as SEER, integrated energy efficiency ratio, or full load EER). Now we are shifting focus and looking at system efficiency and where it is headed in the future.
In this episode, Lindsay Headings sits down with HVACR industry experts Tersh Blissett, Michael Mayberry, Eddie McFarlane, Jerry Rollins, Bryan Orr, and Bill Spohn at The Helix Innovation Center in Dayton, Ohio. Jessica Banister also joins us remotely. Our conversation begins with personal back-stories from the experts, including their passion for HVACR, and how that led them to start their social channels.
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.
In this episode, HVAC School podcast host Bryan Orr is joined by Ryan Gorman, CEO of Coldwell Banker, to give a fresh perspective on a trending topic: College vs. Skilled Trades. A subject that is top of mind for many,
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.
While many homes still use the standard single-stage air conditioner, two-stage and variable speed systems are proving to offer better energy output, efficiency, and dehumidification. Learning more about their differences and benefits can help you guide customers toward making the best choice for their home.
In order for your HVAC system to run correctly and dehumidify the interior space efficiently, your equipment needs to be sized correctly from the start. Installation needs to be done properly with fan speeds set to the desired speed for a balance of efficiency, even temperatures, and moisture reduction. Equipment controls should also be set to a point that will best optimize the system.
As an HVAC contractor, it’s important to know what your customers are looking for when shopping for a new system. Emerson Climate Technologies recently conducted a survey of about 1,500 homeowners on what factors they find most important when purchasing an air conditioning and heating system.
