Understanding Efficiency Ratings

Understanding efficiency ratings helps you compare equipment — but installed Kitsap performance still depends on ducts, charge, and commissioning.

The big acronyms

SEER2/HSPF2 for heat pumps and AC, AFUE for furnaces, UEF for water heaters. Higher can mean lower operating cost when systems are installed correctly.

Why two homes differ on the same rating

Leakage, thermostat setup, filter restriction, and outdoor placement change outcomes more than a 1-point rating gap.

Using ratings in quote comparison

Match AHRI pairs, confirm variable vs single-stage, and ask for Manual J. Beware quotes that only list a SEER number.

Mechanical Home extras ratings omit

Condensate, gas piping, IAQ static pressure, and electrical — all affect whether rated efficiency is reachable.

What goes wrong when homeowners wait

Chasing the highest sticker while refusing duct repairs buys disappointment. Comparing unmatched indoor/outdoor pairs is apples to oranges.

Frequently asked questions

Is SEER2 the only number that matters?

No — heating HSPF2 often matters more for annual Kitsap bills.

Do ratings include duct losses?

No. Ratings are equipment tests, not whole-house results.

Should I wait for next year’s higher ratings?

Usually better to fix a failing system than chase marginal rating bumps.
