About Dor-Mar Columbus Heating And Air
Dor-Mar Columbus Heating And Air has served the Columbus metro area from their Franklin County base, building a track record reflected in their 4.8-star rating drawn from 592 customer reviews. This locally-rooted HVAC contractor handles residential and light commercial systems across Columbus and surrounding neighborhoods, with round-the-clock availability seven days a week. The company maintains a presence on the east side of Columbus and takes calls throughout the greater Franklin County region, offering emergency callouts when heating or cooling systems fail outside normal business hours.
While the company does not publicly list specific brand partnerships on their website, their review profile suggests a broad service scope covering new installations, routine maintenance, and emergency repairs. The 24/7 availability stands out in a market where many contractors keep conventional hours, and multiple reviewers note the company dispatched technicians quickly when urgent situations arose. Their service model appears oriented toward dispatching trained technicians rather than emphasizing specialized equipment or proprietary systems.
Customer narratives from reviews reveal two technicians earning specific praise: Brad earned commendation for diagnostic speed and for teaching homeowners how to maintain their systems between service calls, while Derrick was praised for taking time to explain issues rather than rushing through appointments. One reviewer described an initial consultation where the technician helped size the system correctly without unnecessary upselling, noting the install team worked efficiently once the new heat pump was scheduled. Another reviewer described a same-day service call during a heating emergency, though the outcome was mixed. These named technician experiences suggest a service model where individual technician professionalism shapes the customer experience significantly.
What Customers Say
Four of six detailed reviewers specifically name a technician, with Brad and Derrick each receiving two positive mentions for professionalism and diagnostic skill. Negative reviews focus exclusively on pricing disputes and alleged diagnostic overreach, while positive reviews cite technician demeanor and problem-solving ability. The split between highly satisfied customers referencing specific technicians and dissatisfied customers citing billing concerns suggests outcomes may depend significantly on which technician answers the service call.
