About Bulldogs Heating & Air
A family-owned HVAC company dedicated to keeping your home comfortable with expert heating and cooling solutions since 2005.
Our Story
Bulldogs Heating & Air was founded in 2005 by Billy Johnson, a second-generation HVAC technician with a passion for helping people and a vision for a different kind of service company.
After working for large HVAC corporations for over a decade, Billy grew frustrated with their focus on sales quotas rather than customer needs. With support from his wife Sarah, he decided to start a company that would prioritize quality workmanship, fair pricing, and exceptional customer service.
Starting with just one truck and a small office, Bulldogs Heating & Air quickly gained a reputation for reliability and honest service. As word spread, the company grew steadily, adding experienced technicians who shared Billy's commitment to doing things right.
Today, Bulldogs Heating & Air has become one of the region's most trusted HVAC companies, serving thousands of residential and commercial customers. While we've grown in size, we've never lost sight of our founding principles: treating customers like family, standing behind our work, and providing comfort solutions that last.
