The year 2023 is set to bring major changes to the HVAC industry. The Department of Energy (DOE) has identified inefficiencies in commercial and residential units as one of the main factors contributing to the climate crisis, and has developed a multi-phase standards policy to require the production of higher-efficiency refrigeration units. Starting January 1, the new regulations will change existing minimum efficiency standards in HVAC equipment. The minimum SEER rating will increase on HVAC equipment, with new air conditioners requiring a minimum SEER of 13 in northern states and 14 in southern states.
In addition, the industry will adopt the SEER 2 standard. Heating efficiency will increase from 8.2 HSPF to 8.8 HSPF, and air conditioning systems are changing to SEER2, EER2 and HSPF2 standards. Several manufacturers, including Carrier, will build heat pumps and air conditioners compatible with the R-454b refrigerant. This refrigerant is more environmentally friendly than its predecessors, but it is also slightly flammable.
We cannot upgrade existing equipment to use the new coolant. The changes come from an initiative to reduce total energy consumption in the United States. Split-unit air conditioners that use less than 45,000 BTU must have a minimum of 15 SEER, while split units that use more than 45,000 BTU must have a SEER of 14.5.Southwest states are also subject to new EER rating requirements. Across the country, new air-source heat pumps are subject to a minimum HSPF of 8.8, while new furnaces must have at least an AFUE of 81%.
The DOE also introduced new test conditions, so you'll see a lower minimum number for SEER2, EER2, and HSPF2 compared to equivalent SEER, EER, and HSPF. These new requirements mean that manufacturers of air conditioning systems must redesign any appliance that does not meet these more stringent requirements. You'll see changes in regional standards for HVAC systems through new efficiency standards and an update to older metric systems. While the efficiency requirements of packaged systems do not increase, they will have to pass the new SEER2 and HSPF2 test protocols.
The Office of Energy Efficiency and Renewable Energy states that heating and cooling represent 55% of the energy used in residential homes. So, maximizing efficiency is a key way to keep money in your pocket at the end of each month. If your HVAC unit needs an upgrade, consider installing a high-efficiency system or adding an ERV system to improve performance. A local HVAC service can help you choose the best option for your home.
The DOE's initiative is beneficial for both homeowners and the environment. Homeowners can enjoy HVAC tax credits when upgrading their systems, while also reducing their energy consumption and helping reduce their carbon footprint. With higher efficiency ratings on all types of HVAC equipment, you can reduce your energy bills while still enjoying comfortable temperatures inside your home.
