"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!"

"This company is a breath of fresh air. I answered a flyer in the mail as I was in need of someone to service our heating system. I received a date and time for the serviced. Their service tech called 15 minutes before my appointment to tell me he would be there shortly. He arrived on time, did an excellent job, explained what he was doing, suggested replacing a part that was needed, and basically did exactly what I wanted. Performed a complete inspection, did excellent work, even put on paper slippers to com into our home. We will certainly use them in the future."
