Always great services!

I've been using Dor Mar for my business HVAC, and they always been great. So when my AC unit at my house went out, my first instinct is to get Dor Mar to my house. I lived kinda far out in Delaware, but they did not hesitate to send a technician out to me. They got the job done fast, professional and good price. Definitely would recommend Dor Mar to anyone!

Brandon did a great job!

DorMar was great giving next day service on a frozen AC. Brandon took care on the inspection and gave me my options. I went with the lesser of two evils, but did enroll in their service plan. Great job guys!

Above and beyond

Brad went above and beyond to take care of the issues I had. The previous installer (not Dor Mar) really didn’t do a good job and Brad took the time to remedy a few air leaks. Greatly appreciate him looking out for us.


Response from Dor-Mar Heating & Air Conditioning:

Thank you for the 5 star review, Anthony! We are thrilled to hear that Brad was able to fix your air leaks and went above and beyond for you. We are always happy to help and look forward to serving you in the years to come.

Great customer service!

Well truthfully I had a few issues in the beginning and they were honest mistakes. What I love the most is that Cindy and Drew were so customer focused they made everything right and I will absolutely recommend and use Dor Mar again. In a world of technology it’s the people that make the difference. Cindy is a great asset to your company, good employees are hard to find nowadays. Thanks again Cindy, you kept your word and backed it up by sending Drew. I debated even emailing my concerns but I’m glad I did. Cindy called me right away and stated she would make good on her and boy did she. I’m not use to that with other company’s and typically write them off. I’m glad my co worker recommended Dor Mar and I will for sure recommend them myself. Thanks for all your help Cindy!!!

Recent service

Dormar came through for me when we were really in a bind. They worked with Columbia Gas schedule to complete the work on a furnace. Willie is very experienced and service is his forte. We plan to use Dormar for annual service and any replacements in the future, highly recommend them for HVAC service.

Unit not cooling. Checked operation and found everything running as it should be. Connected gauges to check refrigerant pressures and found system low on refrigerant. Found nut on evaporator coil a loose. Tightened up nut and added 5lbs of 410a to system. System is cooling properly now. Let customer know when we come out for ac maintenance we will check pressures and if we loose charge we will add dye then when the weather is warmer out.
