“The Cornerstone guys came as scheduled and were ready to work. They introduced themselves and showed us what was to be done. They politely answered our questions even though we were interrupting their work; they were very nice about it. The entire process went smoothly and the unit installation was completed. The house started cooling down quickly and we barely hear the new unit. We made an appointment to have the work inspected five days after the installation (which included a Saturday and Sunday). The county inspector stated that they did an excellent job with the installation.
We were surprised to get a fresh set of legible documents with product serial numbers and warranty information for our files, as well as a follow-up call to answer any questions we might have. Overall, my husband and I are satisfied with the choice we made.”
