Air Conditioning Repair Services in Lowell, MA

"Marcin is an extremely talented professional. His expertise saved me during my recent bathroom renovations when we ran into a fit problem with several of the bathroom fixtures. Marcin was able to quickly assess other fixtures that would work in the space, AND without building me a soffit that I really didn*t want! Early on it was clear he*s knowledgeable and dedicated to his craft. Marcin*s involvement and recommendations were super important to the successful completion of the project. If you need a plumbing solution, he*ll make it happen. He and Carlos, his apprentice, worked incredibly hard. It was a pleasure to work with Precision and I would recommend Marcin without hesitation."

"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!"

"Received a call back from Jeff within an hour. He was able to get to my job same day for the same price. Excellent job well done and great communication. Will use him in the future."

"Andy diagnosed the issue quickly and solved it."

"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."

"Mike was above and beyond helpful! He even walked around the house and talked about my air conditioning and heating unit, which was great. He was knowledgeable and did great work."
