Heat Pumps: SEER vs. HSPF

heat-pump
When the time comes to install a new heating and cooling system, it’s especially important to understand the heat pump’s efficiency ratings. This article from the Phoenix HVAC specialists at Precision Air and Plumbing will give you a better understanding of the ratings, SEER and HSPF.

SEER:

  • Stands for Seasonal Energy Efficiency Ratio
  • Applies ONLY to cooling
  • Currently, the minimum SEER you can buy is 13

HSPF:

  • Stands for Heating Season Performance Factor
  • Is a heating pump’s efficiency rating for winter
  • The minimum HSPF available is 7.7

Because heat pumps heat and cool (they are essentially air conditioners with reverse valves that make them run backward in the winter) each function gets its own rating: SEER and HSPF. If the SEER rating is high, the HSPF will be too– but if your heating load is higher than your cooling load, focus on finding a pump with a greater HSPF. Here are a few other tips that will help you choose:

  • Look at your energy bills for the last year or two and determine whether you use heating or cooling most.
  • Enlist a Phoenix heating repair contractor to calculate your home’s energy rating, which shows your home’s annual heating and cooling loads.
  • If you use heating more, go above the minimum HSPF rating and choose a heat pump with a rating of 8 or more.
  • Consider purchasing a thermostat with adaptive recovery, which minimizes your use of supplemental heat in the winter.
  • Air sealing, insulation, and attic ventilation also reduce the amount of heating and cooling your home requires.

      I wanted to make sure my air conditioner was ready for summer. Fernando came out and made sure my unit was tip top. He was friendly, professional and not a sales man. Thanks Fernando!

      Thank you Ray at Precision Air...the compressor on our AC went out last night and the house was HOT. This morning Ray was there to replace the compressor and had us feeling the cool air again in no time. Great customer service...quick response time and friendly from the first call until the repair was completed. Ray even offered to clean the filters! Thank you!!

      Precision Air is a company of integrity. I signed up with them August 1st, 2019 for their AC maintenance plan for 2 years... Someone from their office called me a week ago to set up their yearly maintenance visit. SO GRATEFUL.

      It was time to replace our AC, and so our choice was Precision Air, as we've been with them for over 20 years. Teman & Julian did an excellent job on the installation today, arriving on time.
