Annual HVAC Maintenance

Carrier team were amazing. Besides doing a great job installing new AC, they corrected shoddy work from previous furnace company.

Great work

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.

Very good people to work with.

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.

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.

The estimate, The expertise, and the craftsmanship were all outstanding. I feel like Ive finally moved into the 21st century!

CMS did a great job installing our new Carrier A/C unit. Very pleased with their work and service.

Reliable company, very pleased with the workmanship!

Brien and his entire staff are the class of Longmont. I've had several companies out to diagnose an air flow problem with no success. Brien and Andy spent a couple hours here and found a solution. They care!!

From the start to the finish I was very pleased with their work. Brien came quickly to bid the job and his team did an excellent job. Office staff was extremely helpful and polite! Thank you, CMS!

Fair, honest, knowledgeable and way above the rest in experience, very satisfied.

Dad is 88 years old and I am his daughter /care taker/go to person. From the beginning talking with office gals, assessment of his furnace to the install everything was handled in a fast timely manner with expert service. Thank you all!

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.

Our entire process of getting more heat to the basement has been excellent. Courteous, prompt and very professional.

Seemless and on\-time.

Nice team of people. During the install and they were polite and easy to chat with. Everyone on the team was easy to communicate to about the design, and were on my side about installing in way that was least disruptive to my house.

The install of my new furnace was performed professionally and quickly. Everyone was competent, polite, helpful, and careful. Very pleased with the outcome.

Carroll service was top notch, clean and efficient. I would recommend them to anyone needing heat and air service.

Excellent Service

Even though they are very busy they want to help the customer as much as possible.

Awesome Service and quick/efficient working. Love these guys !

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.

Brien installed a new A/C and brought the system up to code. He was great to work with. Great pricing, and he did a solid job. I would definitely recommend again.

Brien was amazing. Very detailed and took the time to answer all my questions at every step.
