Editorial Review
Our Take on Dor-Mar Columbus Heating And Air
Sixty-plus years in business and a dual "Top Team Contractor" recognition from both Rheem and Coleman are genuine credentials, and covering plumbing alongside HVAC under one company is a real convenience. The company's own site is clearer about its plumbing licensing than its HVAC licensing specifically, which is worth asking about directly.

About Dor-Mar Columbus Heating And Air
Dor-Mar Columbus Heating And Air is the Columbus branch of a family-owned Ohio company that has operated continuously since 1962, headquartered in Newark, OH, about 30 miles east, with a dedicated Columbus office on South Third Street downtown. The Columbus location carries a 4.8 rating from 592 Google reviews, read September 22, 2026, while the company as a whole reports over 1,500 Google reviews and more than 40 full-time employees across its Ohio locations.
Dor-Mar's parent company holds a "Top Team Contractor" recognition from both Rheem and Coleman, two manufacturer programs that recognize dealers on installation quality and training, not just sales volume. That dual recognition across two separate brands is a more specific credential than a generic "certified dealer" badge.
What sets Dor-Mar apart from an HVAC-only shop is that it covers heating, cooling and plumbing under one company, including drain cleaning, leak detection, sewer line work, water heaters and tankless units, radon testing and mitigation, and indoor air quality equipment. For a homeowner dealing with a furnace and a slow drain in the same week, that range means one call instead of two separate contractors.
The company states that after-hours emergency calls are answered by a real person rather than an automated system, and it offers free estimates for new systems and major upgrades. Its maintenance package includes two free HVAC tune-ups and a free plumbing inspection per year, plus discounted service on top of that, a more concrete offer than a vague "annual maintenance plan" claim.
Dor-Mar's site doesn't publish a specific HVAC license number for its technicians on the pages reviewed, stating instead that plumbers are licensed and insured for Ohio residential work; ask for the specific technician's license number directly when booking.
For a Columbus homeowner who wants a long-established, family-owned company covering both HVAC and plumbing with real 24/7 dispatch, Dor-Mar is a solid option, particularly for anyone who wants two manufacturer-recognized service tiers, Rheem and Coleman, rather than a single-brand dealer.
