How to Start a HVAC Business
HVAC has high barriers to entry — licensing, EPA certification, tooling — which is exactly why margins hold up. This guide covers what it actually takes to get started — and the one thing most new owners leave until it's too late.
Licensing first
HVAC is licensed nearly everywhere, and EPA Section 608 certification is required to handle refrigerant. This is not a trade you can start on a weekend.
Service calls vs installs
Installs are big tickets but lumpy. Service calls are smaller and steady. New businesses usually survive on service and grow into installs.
The maintenance plan is the business
A recurring seasonal maintenance agreement is what turns a one-off repair into a customer who calls you every spring and fall. It is the closest thing HVAC has to subscription revenue.
The paperwork
Service ticket, maintenance agreement, equipment worksheet, estimate and invoice. The maintenance agreement is the one that compounds.
