Dor-Mar has been serving Central Ohio since 1962. We’ve grown from a door-to-door operation to more than 40 employees. Starting in Newark, Ohio, we expanded into the Columbus, Ohio metro market several years ago.

Now, Dor-Mar serves Southwest Florida, including Marco Island, Naples and Fort Myers.

See below for all the cities we serve in both Ohio and Florida. We look forward to serving your family’s heating and cooling needs.
