What Is an HSPF2?
Heating Seasonal Performance Factor 2 — the heating-mode efficiency rating for heat pumps, measured the same stricter way SEER2 measures cooling efficiency.
Why It Matters to You
HSPF2 tells you how efficiently a heat pump heats your home in winter, separate from its SEER2 cooling rating — a heat pump you're comparing for Alabama's mild winters should be evaluated on both numbers, not just one.
Practical Guidance
When comparing heat pump quotes, ask for both the SEER2 and HSPF2 ratings — a system can be strong in one and average in the other depending on how it's engineered.
Frequently Asked Questions
Is HSPF2 the same test change as SEER2?
Yes — HSPF2 uses the same 2023 revised testing standard (M1) as SEER2, applying more realistic external static pressure so the rating better reflects real-world ductwork performance.
Why does HSPF2 matter more in some climates than others?
HSPF2 measures heating efficiency, so it matters most in climates with real heating demand. Alabama's winters are milder than northern states, but heat pumps here still run enough hours that the rating affects your winter electric bill.
