What are the major changes coming in 2023 for hvac units?

First, the minimum SEER rating will increase on HVAC equipment. Currently, new air conditioners must have a minimum SEER of 13 in northern states and 14 in southern states. In addition, the industry will adopt the SEER 2 standard. Starting next year, new refrigeration systems will contain a refrigerant with a lower global warming potential.

Several manufacturers, including Carrier, will build heat pumps and air conditioners compatible with the R-454b. 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.

Starting January 1, the new regulations will change existing minimum efficiency standards in HVAC equipment. The DOE identified inefficiencies in commercial and residential units as one of the main factors contributing to the climate crisis. In response, a multi-phase standards policy was developed to require the production of higher-efficiency refrigeration units. SEER regional ratings for cooling systems will increase by 1 SEER.

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 standards. Since 1992, the DOE has regulated HVAC equipment with minimum requirements of efficiency.

This pushes manufacturers to make products as energy efficient as possible, and homeowners can enjoy HVAC tax credits when upgrading their systems. Overall, it's better for the environment and for your utility bills. 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. In addition to the SEER rating, heat pumps also have an HSPF rating. You can reduce the cost of ductless heating and cooling systems if you have 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, which include a SEER2 rating of 13.4 and an HSPF2 of 6.7, or a SEER of 14.0 and an HSPF of 8.0, respectively. However, remember that the improved performance and economic benefits of choosing a high-efficiency heating or cooling system can save you money. in the long term.

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 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 to improve HVAC performance. A local HVAC service can help you choose the best option for your home.
