HVAC by Home Type

A townhome with a shared wall and a rooftop condenser is not the same job as a 1930s bungalow in a historic district with no ductwork, which is not the same job as a manufactured home with a downflow furnace and a crossover duct under the floor. The equipment overlaps. The problems, the constraints and the right answers do not.

These pages are built around what actually differs: the failures common to each kind of home, the systems that suit it, how repair-versus-replace changes, and the design and installation details that decide whether the result works. Landlords and property managers have their own pages, because their questions are operational, not just mechanical.
