"It was so great to talk to Cindy in my time of crisis. 😉 She scheduled someone to be out to my house on the same day as my call, even during this busy season of AC repairs. She made sure I was informed of all the details and benefits of their call-out service including annual inspections on my AC, furnace, and water heaters. It adds real value to the call-out fee. In a separate review, I rated Garett who took care of my AC repair, but I also want to recognize Alexandria who received and addressed a simple follow-up question I had. Well-done all around and thank you all!"

"I wanted to wait on writing my review until our journey with Dor Mar was complete. Brian helped us first, evaluating an old furnace + AC unit at a home we recently purchased. He gave us an honest assessment of our options (repair vs replace,) and we went with a new system. He gave us good advice and helped us choose a system that was right for our budget and home. Matt and Steve removed the old system and installed the new. Like Brian, they were incredibly courteous and professional. Both were knowledgeable and helped teach me about the new system. Brandon came out a week, or so, after the installation to do a quality check of the new system. He was also incredibly helpful and offered sound tips on air flow and balancing it in order to heat/cool our home evenly. Everyone I've spoken to over the phone has also been courteous and knowledgeable. I'd recommend Dor Mar to anyone in need of heating/cooling help!"

"Brian was great! He called before coming to our house, very courteous, asking if 20 minutes was enough time. Arrived within time stated and took time to acknowledge/ pet our dogs, making them feel comfortable. He then went on to explain what he was doing, walked me thru the process as he went along and even waited to check results of his fix. He suggested a few extra services but was not pushy. Overall pleasant experience!"

Review of Dor-Mar Heating & Air Conditioning
Technician arrived on time introduced himself and ordered part for future installation. It definitely wasn't the news I wanted to hear but I felt comfortable and they seem trustworthy. I will update after installation.
Really nice guy that came and saw our system.

Dan – Columbus, OH
Review of Dor-Mar Heating & Air Conditioning
Very good with service. Unfortunately Servicer determined that new furnace installation completed 20 months ago was done poorly / incorrectly and may have even compromised my Rheem furnace with some water damage from ac coil and overall set up of furnace. Yes Dormat is going to correct the installation and make the set up correct, but I won’t have the benefit of knowing if my furnace useful life or warranty will be shorted over time. May be years before knowing. I am moving forward by adding new Ac at the same time as the furnace is reset correctly.
