Thermostat Installation Companies in Lowell, MA

"Carman and his crew did a spectacular job upgrading our old knob and tube panel with 200 amp service. He is punctual and professional, and he stuck by the price he quoted. He showed flexibility when I expanded the job to remove the active knob and tube in the basement and wrapped up both jobs on time. He’s thorough, writing down notes of the work during walkthroughs so as not to miss details. He listened to everything we said we needed and made recommendations. I cannot recommend his services enough, and with all the work required for our home, I will be hiring him for work in the future."

"We hired Pedro Cruz to replace electric baseboard radiators that had rusted due to moisture. He was prompt, professional, courteous and friendly. He replaced both radiators in less than an hour and his rate (to include both radiators) was, in our estimation, extremely reasonable. We would not hesitate to hire Pedro for any other electrical issues we could have in the future. We would highly recommend him to anyone looking for a dependable electrician."

"This was a home run for Cornerstone! Incredible service from start to finish! This was a complete Central AC install including installing all new ductwork. Andy & Britt were incredible. They were on time every day, and very personable. The job they did was great but I also appreciated how it looked. They took the time to tie up all the duct tubes so it was tidy and clean looking in the attic. This was a multi-day install, and there was constant communication on the schedule so I always knew when to expect them. The 2 electricians - Rick & Jeremy were the same. Very relatable and personable, on time and professional. They took care of the electrical install and also tidied up some other wiring. Front office was very professional and courteous, and consistently checking in on the job. Incredibly blown away by the amazing job the entire company did! I would recommend them 1000 times over! Great job to everyone!"

"Daniel worked with me and my schedule, to replace an outlet. He was nice and knowledgeable and priced accordingly. I would hire him again"

"Dan S. and Don N. both did an amazing job. They initially came late, but called to let me know that they schedule had changed, which is appreciated. They were going to replace both the furnace and the AC. They managed to get the furnace into working condition on the first day, which I needed because I had had no heat for the last couple of days. They finished complete installation in a few days. They left the area they worked in clean. They walked me through everything they were doing and why they had made certain choices. Very professional job. Will definitely use them again and recommend them."

"Buck and Wayne installed a mini split heating and cooling system in an attic bedroom/bath. The space was very tight and it took a lot of expertise and creativity on their part to hide all the piping. The outside unit mounted on the back of the house above a porch is a lot more visible than I thought it would be but they did everything they could to make it less intrusive. They arrived before 8 am and had to work outside in some bitter temperatures to install the outdoor unit. At the end of the day, Buck and Wayne took time to made sure that I knew how to operate the unit and that I could call if I had questions. I did a walk-through after they left and the rooms including the attic storage space were spotless. I would highly recommend them for any heating and cooling work you are considering."

"Great work Great company"

"He rewired system to be compatible with ecobee thermostat, diagnosed faulty ecobee unit and came back with a replacement that worked."

"Tingley installed our new Mitsubishi heat pump, including removing our aging furnace and a/c units. The work was done in one day, despite a midstream change of course when the location had to be changed. The team who provided the service was polite, professional, efficient, friendly, and seemingly tireless. I would not hesitate to hire them again and to recommend them to anyone needing HVAC services."
