Heat Pump Repair Services in Rockville, MD

"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."

"Wonderful follow up and customer service"

"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."

"Patrick did an amazing job. He was very upfront & honest with repairs that needed to be completed and the projected cost. I would recommend him 100%."

"At least 5 other companies said that they could not handle the job because our air handler was in the attic and the opening for our stairs was too small to take out the old handler and put in the new one. Air Master Heating's expert, Ken, laughed out loud about that. He said that it would be no problem. He did calculations and we solved the problem with a high efficiency unit. Ken was the estimator and led the installation team. Everyone on the team was hardworking and respectful. They installed the system, cleaned up well and were a pleasure to have in our home. The system is working great and has been very energy efficient. I would recommend this company without hesitation!"

"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."
