If you’ve been shopping for HVAC equipment recently, you may have noticed how many products carry the Energy Star label. While it’s good to know Dallas-Fort Worth has plenty of energy-efficient products available, the abundance can make it hard to tell which products are truly the best of the best.
To help you find highly efficient products, federal Energy Star program experts have introduced the Energy Star Most Efficient program. To qualify for Most Efficient status, a product must meet criteria that place it in the top 5 percent of energy-efficient products in its class. For heating and cooling systems that qualify, these are some of the ratings you can expect:
- Air conditioners – Most Efficient packaged A/C systems, which require ducts and vents, must have a SEER (seasonal energy efficiency ratio) of at least 16 and an EER (energy efficiency ratio) of 12 or higher. Ductless mini split A/Cs, which use indoor air handler units mounted on walls or ceilings, must have a minimum SEER of 18 and EER of 12.5.
- Furnaces – A gas furnace with Most Efficient status must have an AFUE (annual fuel utilization efficiency) of 97 percent or higher. If you can’t find a Most Efficient furnace while shopping for HVAC equipment, for high efficiency look for one that has an AFUE of at least 90 percent.
- Air source heat pumps – Packaged heat pump systems must have a minimum SEER of 16, EER of 12, and HSPF (heating seasonal performance factor) of 8. A split heat pump system must have a SEER of 18, EER of 12.5, and HSPF of 9.6 or higher.
- Geothermal heat pumps – A closed-loop water-to-water geothermal heat pump (for a forced-air system) must achieve an EER of 16.1 and COP (coefficient of performance) of 3.1 or greater. A closed-loop water-to-air geothermal heat pump (for a hydronic radiant system) must have an EER of 17.1 and a COP of 3.6.
