Great locally owned/operated business!
Excellent communication and work from Carroll Mechanical, we have needed no follow-up service whatsoever since the installation. Would use their services again and have recommended them to others. We like using locally-owned/operated businesses!

Great Experience with Carroll Mechanical Services
Very professional staff from sales to scheduling to installation. They did exactly what they committed to at the timing they projected. The office staff even registered my equipment with Carrier to ensure I got the extended warranty. I endeavored to get project estimates from three other local contractors, and the difference between them and CMS in terms of responsiveness, thoroughness, and follow\-through was night and day.

Absolutely happy with our service.
We picked CMS because they had the best price with top of the line equipment out of the 4 bids we got. Everyone was polite and worked hard. The guys were happy to answer any questions and make sure we understood what each piece of equipment did and how to use it.

Great work
Installation of our furnace and AC units went very smoothly. Showed up on time, all the work was completed that day, precautions were taken to keep the carpets clean and such. Everyone was professional and seemed to enjoy what they were doing. Was a great experience and we will for sure continue to use Carroll Mechanical for our needs.

Great experience with Carroll Mechanical Services!
Carroll Mechanical Services came out and replaced my entire air conditioning unit. Their prices were much less expensive than other outfits I explored and their customer service was excellent. I met the owner, Brien, on site and walked through the pricing and installation. It was great to meet and talk with the owner. CMS does things the right way and I would recommend them to anyone looking for an honest bid from a company with excellent customer service.

Carroll Mechanical did a great job
Carroll Mechanical serviced my evaporative cooler and furnace for many years. They have always been prompt, fair, and provided great service. When I decided to covert to central air there was no question who I was going to hire. And once again I am a very satisfied customer.
