HVAC Leads from Building Permits
HVAC companies find leads in building permits by watching mechanical permits (equipment replacements, ductwork, heat pumps) and projects that need new HVAC: additions, remodels and new construction. Mechanical permits pulled by other contractors also reveal where equipment is aging out.

Permit descriptions that signal HVAC work
Mechanical permit, HVAC change-out, condenser, air handler, furnace, heat pump, mini-split, ductwork and boiler. In many cities HVAC work is its own permit type, which makes filtering easy.
The upsell is in the other trades' permits
Additions and finished basements add square footage that existing systems can't handle. Kitchen remodels move ductwork. New construction needs a full system, and builders need reliable mechanical subs.
Turn one job into a relationship
A homeowner who just replaced a system is a candidate for a maintenance agreement. Follow up on installs (yours or anyone's) with a service plan offer about 30 days later.
