My units haven't been services in a few years. I called and scheduled a cleaning and checkup on my heaters and also my a/c units in the spring. The technician was very pleasant, very informative, told me all the steps he was taking and if something was wrong. Thankfully the only thing wrong was a little tube was dry rotting and needs to be replaced - very very thankful!! He was here for about 3.5 hrs cleaning and inspecting both of my heat units. Will definitely recommend Jack Lehr and continue service plans with them. The pricing was very competitive and the technician was wonderful, thoughtful, and very polite.
