Two-Stage Heat Pump
What is a two-stage heat pump?
A two-stage heat pump, also called a dual-stage heat pump, utilizes a two-stage compressor. It has 2 levels of intensity – high (100%) and low (typically 70%). The heat pump will cycle on and off at low speed — first stage — for the majority of the year, until it gets really cold or hot out and needs to jump to high speed — second stage — to keep up. The heat pump will automatically jump between stages in response to the temperature that you set on the thermostat.
How efficient are two-stage heat pumps?
Two-stage heat pumps are highly efficient: they consume less electricity at lower speeds and run for longer periods of time. Long run times circulate air throughout the home, eliminating the likelihood of hot and cold or humid and dry spots.
Once your home has reached your desired temperature, the system will switch to the first stage and continue to run. This fluctuation allows your home to efficiently maintain a steady, even temperature and humidity level.
SEER Ratings
All central ACs were required to have a minimum SEER rating of 10 in 1992 and by 2006 that minimum was raised to 13. In certain regions of the country, like the south and southwest, that minimum standard is raised even farther to 14.
In 2023, regulations will require a minimum SEER of 14 for the northern U.S. and 15 for the southern U.S.
Year North South & SW 1992 10 10 2006 13 13 2015 13 14 2023 14 15
SEER ratings are compiled using standard formulas to help you determine how much you can expect to pay annually in energy costs. This lets you compare air conditioning units and pick the one that best suits your needs.
