How Condensus works

A reference, not a review blog

Makers' own figures

Capacity, SEER2, HSPF2 and low-temperature heating come from each maker's or seller's own published specifications. If a maker doesn't state something, we say so instead of guessing.

Sized to your room

Our calculators start from the ENERGY STAR room sizing chart and show every assumption, so you can see why a system is or isn't the right size.

2026, as it is

The federal 25C credit ended for systems installed after 2025, and new systems use R-32 or R-454B refrigerant. We flag refrigerant and electrical work that needs a licensed installer. How we research.
