"I totally recommend this company. They are honest and truly care about the customer. I previously had a couple of different quotes from other companies and D Mechanical gave the best quote. I did not have the money to replace my entire air conditioning unit at the time. They offered a couple of alternatives that were cost sufficient. Not only did they do a great job but they were prompt, professional, informative, and very efficient."
