Heat Pump Installation Contractors in Andover, MA

"Jake diagnosed a long running problem with my ac system (a poorly performing thermostat) and fixed it."

"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!"

"Joe called to our house the evening we submitted our contractor search on service magic. He was very helpful/clear/informative in explaining our options. The furnace installation was done on the day we asked. The guys who installed the furnace were on time did a quick, neat job and explained everything as they went along and did a full clean up at the end. All in all the job was excellent and I would definitely recomend Airco in the future."
