The Department of Energy (DOE) has been regulating HVAC equipment since 1992, setting minimum efficiency requirements to push manufacturers to make their products as energy-efficient as possible. Homeowners can also benefit from tax credits for heating, ventilation, and air conditioning if they upgrade their systems. In 2023, the DOE is introducing new standards for HVAC systems that will have a significant impact on the efficiency of cooling and heating systems across the country. The regional SEER ratings for cooling systems will increase by 1 SEER, while heating efficiency will increase from 8.2 HSPF to 8.8 HSPF. The classification standards for ovens will be 81% AFUE for the three regions.
Air conditioning systems are changing to SEER2, EER2, and HSPF2. Split-unit air conditioners that use less than 45,000 BTU must have a minimum of 15 SEER, while split-unit units that use more than 45,000 BTU must have an 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. You can reduce the cost of ductless heating and cooling systems by having high SEER and HSPF ratings. 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. Therefore, maximizing efficiency is a good way to keep money in your pocket at the end of each month. If your HVAC unit needs to be upgraded, consider installing a high-efficiency HVAC system or adding an ERV system for improved performance. A local HVAC service can help you choose the best option for your home.
You can request up to 30% of the cost of the work, subject to maximum limits.
