Customer Testimonials


Gas Furnace Repair in Round Lake Beach, IL 60073

“Corey came out within 40 minutes of my call on Thanksgiving Day. He explained each of his diagnoses in understandable detail. Unfortunately the first diagnosis was wrong. While acting on his second diagnosis he discovered a loose connection which was causing the whole problem all along. This is not a complaint, I know it's always a process of elimination. And I was very pleased that nothing needed to be replaced, so it only cost me the service call. Corey was also very nice to deal with. He represents your business well. Thanks again for taking care of us all these years.” – Jeff L.
