How HVAC companies find jobs in building permits

Permits point HVAC companies to two kinds of work: new systems in new buildings, and replacements in older neighborhoods. Here is how to read both, and when to reach out.

Two kinds of HVAC work in permits

Building permits point HVAC companies to two very different kinds of work: new systems in new buildings and additions, and replacements of old systems in existing homes. Each one needs a different approach.

New builds: the builder decides

A new house or a large addition needs a new heating and cooling system, and the builder picks the HVAC contractor early in the build. By the time the house is framed, the choice is usually made.

Visit the busiest builders

For new construction, your customer is the builder, not the future owner. Count the new-home permits per builder near you; the few at the top file most of the work. Meet them before their next project starts.

Replacements show aging neighborhoods

Mechanical permits for system replacements tell you something else: which neighborhoods have equipment reaching the end of its life.

Where: the streets where replacements are being filed.
When: how many in the last few months.
What: the type of equipment, when the city describes it.

Same street, same age

Homes built in the same years often have equipment of the same age. When replacements cluster on a street, the neighbors may be next. Within your local rules, that street is worth a mailing or a visit.

New systems need care

Every new system needs maintenance. When a new home passes its final inspection, the owners are moving in with equipment nobody services yet: a good moment to offer a maintenance plan.
