Our Story

The DorMar story began in 1962, fueled by the grit of a U.S. Navy veteran and a dream to serve the community. What started as a dedicated door-to-door operation has since evolved from a local heating and cooling shop into a comprehensive home services leader across Central Ohio and Florida.

Even our name, DorMar, is rooted in the personal connections that started it all—named in honor of Dorothy and Martha, the wives of the original founders.

Three Generations of Service

Family isn’t just part of our history; it’s our foundation. For over six decades, leadership has passed down through three generations, ensuring that our core values remain as steady as the homes we service.

  • The First Generation: Founded on post-WWII discipline and 20 years of expertise, establishing a commitment to honest, local service.
  • The Second Generation: Expanded our reach and deepened our community roots, initiating our long-standing tradition of supporting local youth athletics and Little League teams.
  • The Third Generation: Our current owner grew up in the family business, spending summer vacations running ductwork and learning every facet of the trade from the ground up.

More Than Just HVAC

As the needs of our neighbors grew, so did we. While our roots are in heating and cooling, we have evolved into a full-scale home service company. Today, our multi-generational expertise extends across a wide range of essential services to keep your home safe and comfortable:

  • HVAC: Expert heating and cooling solutions.
  • Plumbing: Professional care for your home’s vital systems.
  • Radon Mitigation: Protecting your family’s health and safety.

Our Promise to You

Today, we honor our 60-year tradition by treating every customer like family. We remain focused on the same principles that guided us in 1962: reliability, friendliness, and lightning-fast service.
