Our heat and air system were getting old and inefficient. Our utility bills were growing astronomically. The temperature in each room of our 2 story home varied tremendously. J & K Heating and Air recommended replacing both units as well as reworking the ductwork and adding insulation in the attic. The re-engineering of the ductwork was impressive. A few small changes have made the temperature in every room the same! The size of the units they installed seems to be a perfect match for our home. Instead of being amazed at how high our utility bills are, we’re stunned at how much lower they are. Mark, Kevin, and the entire crew are very professional and worried about every detail. They are very friendly and easy to work with. They treat you better than family.
