Overview

Residential HVAC Equipment covers furnaces, air conditioners, heat pumps, and residential heating-and-cooling systems. It is a consolidated, replacement-driven segment dominated by majors (Carrier, Trane Technologies, Lennox, Daikin/Goodman, Rheem, Nortek) selling primarily through HVAC contractors and distributors.

Demand is anchored by replacement of a huge installed base (most sales are replacement, not new construction) and is being transformed by heat-pump electrification — supercharged by Inflation Reduction Act incentives — and the low-GWP refrigerant transition. It is one of the most attractive building-equipment segments, with strong brands, recurring replacement, and a powerful electrification tailwind.
