What is email marketing for HVAC companies?

Email marketing for HVAC companies involves using targeted email campaigns to stay connected with customers from the initial installation of their equipment or service through annual maintenance to eventual replacement.

Unlike spray-and-pray advertising, email marketing for HVAC companies segments customers by equipment age, service history, or property type, then sends personalized messages when relevant and appropriate.

For HVAC contractors, this includes automated appointment reminders, seasonal tune-up campaigns, filter change alerts, and equipment replacement nurturing sequences. The goal? Keep your schedule full year-round while building the customer relationships that turn one-time service calls into lifetime maintenance contracts. HubSpot’s free email marketing tools are a great choice for HVAC companies.
