Heat Pump Repair Services in Rockville, MD

"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."

"Wonderful follow up and customer service"

"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."

"The service I received was highly professional. Everyone involved was very communicative, prompt, and kind. All our needs were meet and the work is top quality."

"Moises, the company owner, is incredible. I called 5 HVAC companies to get quotes for full system replacement, and MSR was not only the most responsive, but he came out the very next day. He gave me an incredibly competitive and fair quote for my project, and we immediately gave him our business. Unfortunately, our AC died before he could do the work, but he came out to our house at 6pm on a Friday to drop off a portable AC unit so we wouldn't sweat all night long. We thought we'd be stuck without central air for a few days, but Moises came and worked 9 hours on a Saturday to replace both our furnace and our AC unit. Afterwards, he even gave us a great price on a yearly HVAC maintenance plan. MSR is run by an honest, hard-working tradesman who understands what customers want and need. I won't hesitate to recommend him to friends or to anyone who needs HVAC work done."

"Replacement of my heat pump units, both inside and outside, was done nicely. Recommend this business."

"Love the professionalism and the advice. Would definetely hire them again."

"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."

"Repair technician was very knowledgeable and gave advice for avoiding problems in the future. I will definitely call this company again for routine maintenance as well as emergency repairs."
