Dor Mar Heating & Air ConditioningExcellentDor Mar Heating & Air Conditioning4.6★★★★☆ Based on 1358 reviews fromSee all reviews review us onPLANEGANG TvPLANEGANG Tv ★☆☆☆☆ These guys come out and fix an issue but cause another one in the process to charge you for the follow up visit. They are slick.Elijah WilliamsElijah Williams ★★★★★ Dor Mar hires great prospects who provide excellent service. My tech, Preston, came and knocked the job out of the park — I’ve had 3 different companies come out and inspect my heat pump several times but we got no where. Wasted money and wasted time.Not only did Preston diagnose the problem on the first visit, he explained everything well enough for me to understand what needed to be done, ordered the parts and had my AC running the next week — Very satisfied! 10/10Response from the ownerWe truly appreciate you leaving a thoughtful review for our technician Elijah.

What they lack in knowledge they make up for with deceit.Response from the ownerUnfortunately we are not able to locate you in our system, we would like to look into the service you had done to see how we can improve. Please reach out to our Customer Satisfaction Manager kayden@dormarhvac.com or call into the office and ask for her directly so we may get to the bottom of this. Juanita RamseyJuanita Ramsey ★☆☆☆☆ Dor Mar sent out a employee to drain my hot water heater as part of a maintenance program that I paid for. That employee spent most of the time walking around the inside of my house (my hot water tank is in the basement with an outside access only) taking pictures of all of my plumbing. He did not ask to do this he just started taking pictures saying he was supposed to. He opened my cabinet under my sink and wanted to know why I had a bucket there. (it was to carry cleaning supplies in when cleaning around the house)Then he told me that there was a problem with my tank since he emptied it and it was leaking. I asked him how much it would cost to fix it and he immediately said $2700.00. I told him just to turn the water off to the tank and to just leave. He had placed a bucket under where it was leaking, and he said I won't have hot water. If he turned it off. He then tightens the screw a little more and then it quit leaking.Another problem I had was I told him he could park beside the house (I showed him where) but for some reason he just wanted to walk through the front door and through the house and then out the back door. He did this about 3-4 times.Finally, when he was done, I opened the gate so that he wouldn't walk through my house again and he went straight to the front door saying he was so sorry, but he had lost all of the pictures that he took and had to come in to retake them all again. At this point I was ready to call the sheriff to escort him off the property. I did let him take the pictures and finally he was off.He was polite when talking to me I have no issues there, but all the other stuff was unnecessary... He was there to drain my hot water tank not to do a photo shoot. I will try to come to the office on Monday I am still extremely upset about this. IT IS NOT THE WAY TO DO BUSINESS!Response from the ownerFrom your description of what the technician did while in your home perfectly describes our Plumbing maintenance Juanita. The plumbing maintenance includes a check on the entire plumbing of the home and the flushing of your hot water tank, we do apologize if that was not properly explained to you when your service was booked. It is also unfortunate the tech couldn't follow the directions you offered to not have to walk through the home and we apologize for that, over all we hope this gives you some ese on what was done by the tech as he was just doing his job. S HawkinsS Hawkins ★★★★★ Anthony was greatResponse from the ownerThank you for leaving our tech a great review! Angela SeymourAngela Seymour ★★★★☆ The service was great. But they don't honor their service windows. My service windows was 12-4 and I get a message at 9:40 that the tech was on the way. I had to rearrange my schedule to fit in the cleaning. Luckily I was close by and could make it to the house in time.Response from the ownerWe apologize there was an issue with your scheduling, we always try our best to make our time frames, in the future wed be more than happy to have the Tech wait for the scheduled time frame had we known it was an issue for you to make the appointment earlier.
