Thermostat Installation Companies in Rockville, MD

"David was very knowledgeable and explained things very well. He was very pleasant and professional."

"Will is a great find through Angi. He was very knowledgeable about the Ecobee Smart Thermostat installation even though we had old 8 wired with jumper thermostats for two zoned electric heat pumps. I was so impressed with his knowledge that I asked him to do our HVAC system tune-ups as well. He quickly assessed that our heating had more electrical loads than what we really needed - something that PEPCO has alerted us before. Will was a totally honest professional who had started his company two years ago. However I have found him to be very honest and straightforward in his profession and conscientious about not doing unnecessary work unless it was needed. I plan to use him for our future services including plumbing and electric floor heating as I trust his ability to handle any technical issues for my home."

"I called Carroll Mechanical for an estimate on a new high efficiency heat pump system. I met with a member of their team that clearly explained everything and helped to design a solution that worked for my family at a fair price. The install team arrived on time, they were very polished, and did a technically excellent job. The system is working really well and the whole family is comfortable! Couldn’t have asked for more - I’ll be using Carroll Mechanical as my go to HVAC contractor from here on out."

"Mr. Viera was on time, I got a 30-45 min call ahead before his arrival, and he was promptly, he is very friendly, professional when he arrived, told me that not to worry, that the issues I was having with my AC that he was gonna take care of it, and he was also was gonna go beyond to make sure that my whole system, was not gonna fail as long as he thoroughly checked it, and let me know if there was anything else that needed to be taken care of it while he was here. So I definitely would hire this company again, and recommend it to anyone in the DMV area."
