Choosing the right heat pump system isn’t just about heating and cooling—it’s about energy performance, comfort, and long-term savings. Two of the most important HVAC efficiency ratings to understand today are SEER2 and HSPF2.

At Wells HVAC Supply, we help homeowners and contractors choose systems that meet the newest efficiency standards, reduce operating costs, and deliver reliable year-round comfort.

What Is SEER2 in HVAC Systems?

SEER2 (Seasonal Energy Efficiency Ratio 2) is the updated measurement of how efficiently your heat pump or air conditioner cools your home during the summer. It represents the total cooling output divided by the total electrical energy used during the season.

Typical SEER2 Ranges:

• Standard Efficiency: 13–15 SEER2

• High Efficiency: 16–18 SEER2

• Premium Models: 19 SEER2 and above

A higher SEER2 heat pump means more cooling comfort with less electricity, helping reduce monthly energy bills and increase overall system performance.

What Is HSPF2 and Why Does It Matter?

HSPF2 (Heating Seasonal Performance Factor 2) measures how efficiently a heat pump provides heating during colder months.
It’s the ratio of total heat output to electricity consumed—so the higher the HSPF2 rating, the more efficient your heat pump is in heating mode.

Typical HSPF2 Ranges:

• Standard models: 8–9 HSPF2

• High-efficiency models: 10–11 HSPF2 or higher

When choosing a cold-climate heat pump, pay close attention to the HSPF2 rating—it determines how effectively your system can deliver warmth even in freezing conditions.

SEER2 and HSPF2: What Changed from the Previous Standards?

The U.S. Department of Energy introduced SEER2 and HSPF2 to replace the old SEER and HSPF ratings starting in 2023.
These new standards simulate real-world HVAC conditions, taking into account factors like duct resistance, external pressure, and air distribution losses.

The result? More accurate efficiency ratings and better system comparisons for homeowners and contractors.
At Wells HVAC Supply, every modern Wells Heat Pump complies with SEER2 and HSPF2 standards, ensuring certified performance and lasting comfort.

How to Choose the Right Heat Pump Efficiency Level

When selecting a new heat pump system, consider:

• Climate zone and temperature extremes

• Home or building size

• Desired energy savings and rebate eligibility

• Upfront cost vs. lifetime energy efficiency

A higher SEER2 and HSPF2 rating often means better long-term savings, quieter operation, and compatibility with incentive programs like ComEd energy rebates (available through contractors).
