Air Conditioner Installers 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."

"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."

"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%."

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

"Sales rep was only one of the contractors bidding to actually do measurements, and spent more than an hour looking at my system to figure out why I was having issues."

"Henry was professional and thorough. He went out his was to see that our heat was restored on the coldest day of the year. You can spend a significant amount of money dealing with the big HVAC advertisers in our market but why pay for their ads when you really want competent service? This company provided me everything I expected in a repair."

"We decided to replace our 16 year old AC and furnace as we wanted to prevent possible problems with our HVAC system. The heating consultant that they sent, Alex H, was very friendly and knowledgeable. He provided us with estimates for a number of options - similar to those from other HVAC companies that quoted for this work. A day later I received a call from Blue Dot offering a discount on that quote and we accepted that quote. Alex made the one and a half hour drive to visit with us again, to walk us through the contract details, and to explain install process. This was a really nice touch as usually contracts are signed electronically these days. The Blue Dot install team came on time on the scheduled day and did a neat and professional job with the install - performing all the necessary checks and tests, and left the work area clean and tidy - and with the HVAC systems working well. The whole purchase and install process couldn't have gone smoother. We are very happy with BlueDot and will certainly use them again preferentially for our HVAC needs."
