When installing or upgrading your AC unit, you should ask yourself: What is SEER2? In the past, older HVAC systems have operated based on SEER, which measures how effectively an AC converts electricity into cooling power. SEER ratios are calculated by dividing the total cooling output by the total energy consumed by the system during the same period (i.e., the warm season).
The higher the SEER rating, the more efficient the system is. Recently, there’s been a shift toward modifying HVAC efficiency requirements to SEER2 to revolutionize the industry so that units are better at cooling, relying on less energy. Since those former qualifications equate with higher power usage and utility bills, it’s best to consider swapping your AC unit for the SEER2 alternatives.
If you’re looking to know what SEER2 is, our HVAC experts at Fairway Heating and Cooling in the Tampa Bay, Florida, area have provided detailed information to help you make an informed decision for your home.
What Is SEER2?
SEER2 is the new seasonal energy efficient ratio, which refers to the energy consumed for your heating and cooling system over an entire year to evaluate overall equipment performance. When calculating the numerical value, the ratio measures the total heat removed from an air-conditioned space, expressed in Btu, divided by the total electrical energy consumed (from the AC or heat pump) during the season (in watt-hours).
While SEER (the old efficiency standard) has been a dominant force in decision-making for HVAC systems in the past, these qualifications have recently changed. As of January 1, 2023, the Department of Energy (DOE) enacted all new units to be SEER2 compliant regardless of the state or local code. These new standards call for a minimum of 14 SEER on all HVAC (14.3 SEER2 equivalent).
With this, testing protocols have been updated and improved to include higher external static pressures and are meant to represent real-life usage better to maximize accuracy. Unlike SEER, SEER 2 evaluations will look for coil-only units’ fan power, heat load calculations, heating modes, off modes, and variable speed factors. However, it’s essential to know that these requirements differ slightly in Southern regions of the United States.
The DOE does not allow “sell-through,” or selling and installing products meeting old efficiency requirements in the Southeast and Southwest. In the North, compliance is based on the date of manufacture, while the other two regions are based on the date of installation for AC products and the date of manufacture for heat pumps.
When installing a new HVAC system, it’s necessary to ensure all units adhere to SEER2 criteria.
How SEER2 Is Revolutionizing HVAC Efficiency
The Earth is becoming warmer each year. The Intergovernmental Panel On Climate Change (IPCC) report warns that surface temperatures will likely rise about 1.5 degrees Celsius by 2050. As a result, global warming can put 75% of the world’s population at risk of deadly heat exposure, increasing reliance on AC systems.
With older units, global warming will worsen. So, the recent effort toward maximizing efficiency will limit the environmental impact of HVAC systems, revolutionizing the industry to lower the effects of climate change. Making these changes is monumental for preventing global warming from worsening. It also improves cooling systems and reduces heat-related health issues.
