Melissa Crenshaw

We had a major HVAC job completed this week by Dulin Mechanical, and I cannot say enough good things about this company and their team. From start to finish, the entire crew was incredibly respectful, professional, and hardworking. They showed up ready to work and stayed busy the whole time, clearly taking pride in doing the job right. It’s rare these days to see a team that is not only skilled but also courteous and considerate while working in your home. They were efficient, communicated well, and left everything in great shape when the job was finished. We are very happy with the work they did for us and the entire experience. I would absolutely recommend Dulin Mechanical to anyone needing HVAC work, and we will definitely use them again in the future!

Chance was fantastic. Honest and straightforward, and their pricing is definitely competitive. Replaced my 25 year old furnace with a new Trane system, looking forward to not having to worry about heating for a while!

I can't express how much we appreciate Dulin Mechanical this week!! We were dealing with the breaker tripping, no heat and they were there for us at every turn until it was FIXED!! They never ignored a call or text. Knowledgeable and empathetic, great people!! Thank you, John, Megan, Colby and tyler!! John checked our unit from outside to the attic ,( twice) Colby also checked our unit! 3 days and they found the problem was a weak breaker. It was a frustrating week but they came through for us and we were priced reasonably!! Highly recommend ??

Dulin is the best HVAC service company in the Charlotte area! Their service technicians do a thorough job in their inspections and explain the results of testing and findings in a professional way. They have kept my heating and air conditioning systems in A-1 condition through the years in a cost effective manner.

EXCELLENT company. Dulin has always under-promised and over-delivered! They said they could TRY to fit us in within a couple days, but came roughly an hour and a half later! Did their work (always in good spirits) and off they went. Our HVAC works swimmingly! Thank you Dulin.
