About Condensus

Condensus is a reference for ductless mini-splits, multi-zone systems, window and through-the-wall heat pumps, and the line sets, brackets, condensate pumps and controls that go with them.

The numbers that decide a heat pump are spread across spec sheets and listings: cooling and heating capacity, SEER2 and HSPF2, how cold it can still heat, line-set length, voltage and which indoor heads work with which condenser. We put them side by side, with calculators that size a system to your rooms.

Condensus is an independent publication. We don't sell products and we don't accept payment for coverage. Some links earn us a commission; see our affiliate disclosure.
