What is HSPF in an HVAC system?

The HSPF, or heating seasonal performance factor, is a rating that measures the efficiency of the heating mode of a heat pump over an entire heating season. The higher the HSPF rating, the more efficient the unit and the lower your energy costs will be. When shopping for a new heat pump, be sure to ask about the HSPF rating to ensure you’re getting a high-efficiency unit.

What is a good HSPF?

A good HSPF rating is anything above 9.0.

What is the highest HSPF on a heat pump?

The highest efficiency heat pumps on the market have ratings of up to 13.0.

The HSPF rating is based on the amount of heating energy the unit uses over the course of a season, as well as the outdoor temperature during that time. The more efficient the unit, the lower the energy use and the higher the HSPF rating will be.

What are the benefits of a high HSPF?

The benefits of a high HPSF include:

  • lower energy costs,
  • reduced emissions of greenhouse gases,
  • and improved comfort in your home.

A high-efficiency heat pump can save you hundreds of dollars each year on your energy bills, while also helping to protect the environment.

Is HSPF and SEER the same?

No, HSPF is the heating seasonal performance factor while SEER is the cooling seasonal energy efficiency ratio. Both ratings are important when choosing a new heat pump, as they will both impact your energy costs. Be sure to ask about both ratings when shopping for a new unit.

Which is the more important SEER or HSPF?

Both SEER and HSPF are important when choosing a new heat pump. SEER measures the cooling efficiency while HSPF measures the heating efficiency. Depending on your climate, one rating may be more important to you than the other.
