Dennis (my serviceman) remembered me from 2 years ago. He gave a quick check of my system and assured me everything was AOK. He also took the time to clean out the outside unit. When I asked if it was possible to replacement my current thermostat with a smart one that would switch between A/C and heat automatically, he gave me a fair price and installed a nice one that could be programmed for every day of the week individually. Then he programmed it for me. No more waking up to too hot or too cold! All in all, great service from a great serviceman and company.
