HSPF Rating? What the $#%@ is That?!

What is HSPF rating

If you are an HVAC novice, you may wonder what HSPF Rating is...In this article, we are here to let you know!
You might've heard or read about HSPF rating when looking at the efficiency of your HVAC system. This blog will answer your questions as well as address the significance of HSPF ratings when it comes to energy efficiency with HVAC units.
What is HSPF Rating?
HSPF, or Heating Seasonal Performance Factor, is the ratio of BTU heat output and the watt-hours of electricity used over the heating season. BTU is a measurement of the energy efficiency of an appliance: how much heat is required to raise the temperature of one pound of water one degree Fahrenheit. So an HSPF rating compares how much heat a heater produces to how much energy it uses.
It is also important to know that HSPF ratings are only used for heat pump systems (both ducted and ductless). This is because heat pumps use electricity and HSPF measures heat energy output to electrical energy input. Watch the video below to learn some more about HSPF for heat pump systems. 
Similar to AFUE ratings, the higher the percentage, the more efficient the unit. HSPF can range from 6.8 to 13.5. The lowest HSPF rating for a heat pump to be considered ENERGY STAR rated is 8.2 for single package units and 8.5 for split systems. A traditional system falls between 6.8 and 7.7.
SEER Rating
What is HSPF?
SEER, Seasonal Energy Efficiency Ratio, is normally
the selling point for mini-split and traditional systems,
but the SEER rating only measures the cooling
efficiency (while HSPF rating measures both heating
and cooling efficiency). If your system both cools and heats the house, you want to know how it will function
in both extremes. This is especially important if your heating load is higher than your cooling. If you find
yourself spending more money to heat your house than cool it, a high HSPF rating is just as important, if not
more important than SEER.

What systems have the highest HSPF Ratings?

Mitsubishi MSZ-FS wall mounted indoor unit heat pump system
One highly efficient system that provides elevated comfort for your home is the Mitsubishi MSZ-FS Deluxe Wall-Mounted Indoor Unit (left). This unit can have an HSPF rating as high as 13.5, and a SEER rating up to 33.1. The reason being, these units are built to meet your needs, being exceptionally energy-efficient and using less wasted and unnecessary energy all while providing better overall air quality with a state-of-the-art design. The unit is also equipped with a 6,000 to 18,000 BTU/H capacity and a COP that is up to 4.68.
Another similar system that provides high
Mitsubishi MSZ-GL wall mounted indoor unit heat pump system
efficiency and highly satisfactory heating and cooling inside your home is the Mitsubishi MSZ-GL Wall-Mounted Indoor Unit (right). This unit, a cousin to the MSZ-FS above, is equipped with a 6,000 to 24,000 BTU/H capacity itself and a SEER rating up to 24.6, while its HSPF rating can be as high as 12.8. Both this unit and the Mitsubishi MSZ-FS can come equipped with a single-zone hyper heat system, multi-zone heat pump, multi-zone hyper heat system, and more!

Where do I go to find more information and what is right for me?

Speaking or meeting with a professional contractor is the best way to get more detailed information and find out the most energy-efficient solution for your home. For more information about heat pump systems, including how they work, what makes them stand out, and what makes them so energy-efficient, click here. To find out more information about Mitsubishi Hyper-Heat heat pumps (from above) and how they provide maximum comfort through heating and air conditioning click here.
