Hollis, NH Homeowner Seeks Advice When Purchasing A New Unit
There are three different rating systems to measure the efficiency of a heating and air conditioning system. EER (Energy Efficiency Rating) determines the cooling output in BTUs comparative to watt-hours of electricity. This measurement is most often used for determining the efficiency of smaller HVAC units, like window air conditioners. SEER (Seasonal Energy Efficiency Rating) can provide a bigger picture of the efficiency of your unit because it looks at both hot and cold days. This is a common measurement homeowners look at when considering a new HVAC system. HSPF (Heating Seasonal Performance Factor) specifically measures the efficiency of the heat pump.
A homeowner in Hollis was looking to replace her HVAC unit. Wanting something with excellent energy efficiency, she contacted the team at Joyce Cooling & Heating Inc. for advice.
For Big Picture of Energy Efficiency, Consider the SEER (Seasonal Energy Efficiency Rating)
The SEER rating is one of the most important when considering the energy efficiency of a new HVAC unit. This rating is determined based on the cooling output over a season, compared to how much energy is used. This is one of the most accurate ratings because it looks at an entire season, instead of a smaller snapshot in time. A good SEER rating is 14 or higher, with most new units averaging a SEER rating of 16. Some of the most energy efficient models can have a rating up to 23.
HBSF (Heating Seasonal Performance Factor) for Heat Pump Efficiency
A home’s heat pump’s efficiency is measured by an HSPF rating. You can also look for the Energy Star label for the most energy efficient heat pumps. To qualify for the EPA’s high standard of Energy Star, heat pumps must have an HBSF rating of 8.2 or higher. These most energy efficient heat pumps also must have a SEER rating of 12 or higher to receive the Energy Star label. Most of today’s heat pumps have a rating between 8 and 10.
With this information about HVAC system efficiency ratings, the homeowner in Hollis was able to choose a new unit that will reduce the amount of energy used and save her money in the long run.
