I had an excellent experience with Kieffer’s Heating and Cooling. From the very first call, Kieffer was incredibly responsive and quick to schedule service. He was not only on time but also extremely thorough, making sure to check everything carefully and explain the work in detail. His professionalism stood out—I felt confident that my system was in great hands. One of the biggest highlights was how he went the extra mile to get my system’s mobile app up and running, walking me through the setup so I can easily monitor and ... read more
