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!!!

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.

I am a highly skilled and experienced home service professional. I recently completed a plumbing maintenance job at a new build home that is about 5 years old. The home has three full baths, two on the first floor and one on the second. During my inspection, I thoroughly checked all the toilets in the home. I flushed each toilet multiple times to ensure there was no water at the base or the supply line, and I checked to see if they wobbled. I also inspected all the laboratory faucets in the home. They had the push pop-up assembly, and all of them worked perfectly, with no stuck or dripping issues. I also checked the tub shower combos in the home. They all worked great and appeared to be in excellent condition. I turned off the water to the tub and shower faucets and checked for any water dripping underneath the cabinets.

The humidifier was installed in the basement of the home and was connected to the home's central heating and air conditioning system. The humidifier was installed in a closet and was connected to the home's ductwork. The humidifier was installed by removing the old humidifier and installing the new humidifier in its place. The humidifier was then connected to the home's electrical system and the ductwork was sealed. The humidifier was then tested to ensure that it was working properly.

I was called to a home to inspect a Goodman furnace that was not working. Upon arrival, I found that the furnace was running great, firing up well with good amp draws on the inducer motor and blower. I cleaned the flame sensor, checked the ohms on the igniter, and made sure there was a clean filter in the filter slide. I also checked the gas pressure and found it to be within the manufacturer's specifications. I then explained to the homeowner the steps I took to diagnose and repair the furnace, and I provided them with a detailed estimate for the repairs. I also offered to provide them with a maintenance agreement to ensure that their furnace continues to run smoothly. The homeowner was very pleased with the service and agreed to the maintenance agreement.
