    Raymond and his crew @ Cornerstone were great to work with and delivered a quality product.  I was unfamiliar with large scale floor heating systems, and they walked me through the different options available.  I am very happy with the results and would recommend Cornerstone for anyone looking for an HVAC solution to their shop, office, or home.

    We have been very happy with Cornerstone. They installed a new furnace and air conditioning system, and put in new duct work to reach our upstairs. Everything is working great, and they always return our calls in a timely manner.

    Cornerstone Comfort has been meeting our heating/cooling needs for many years.  We have always been very satisfied with their service! With the installation of our new closed-loop geothermal unit, we were not disappointed.  There was great attention to detail with the removal of the old unit, the installation of the new unit and making sure I understand how to operate the new system.  I highly recommend them!
