Excellent Service!

James was professional and very efficient during our duct and dryer vent cleaning today. I especially appreciated his patience with our German shepherd dog. Scheduling was simple and clear and they got us in super quick. Definitely happy with this service today.

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.

I arrived at the customer's home to perform a routine maintenance check on their air conditioning unit. Upon arrival, I found the unit low on charge. I added 2 pounds of R410a refrigerant to the system and then performed a dye leak detection test to ensure there were no leaks. Afterward, I checked the pressures and verified that the unit was operating properly.

I arrived at the customer's home to perform a plumbing, maintenance, and radon checklist. I completed the plumbing and maintenance tasks and found that the unit was running properly. I also completed the radon checklist and found that the levels were within the acceptable range. The customer was satisfied with the work and thanked me for my service.

I am a home service technician. I contacted the landlord and emailed an estimate for the replacement of the damaged roof. I also informed the landlord that I would be available to perform the work within the next few days.

I arrived at the customer's house to perform a routine maintenance check on their heating and air conditioning system. I ran the unit in the air conditioning mode to check for a temperature split. I also checked the amps and ohms on both the indoor and outdoor units to ensure they were within the manufacturer's specifications. I checked the wiring and pressure on the outside unit to ensure they were functioning properly. Finally, I performed a radon test to check for any potential radon gas in the home.

I am a highly skilled home service professional who specializes in repairing and maintaining various household appliances. Recently, I completed a job at a client's home where I replaced a faulty refrigerator compressor. The compressor was making a loud noise and was not cooling the refrigerator properly. After replacing the compressor, the refrigerator was back to normal and the client was very happy with the service.
