One chilly morning on Sheridan Road… The O'Connor family's aging mercury thermostat failed to call for heat. Their Colonial-style home off Sheridan Road, just a short walk from Ravinia Festival grounds and Sunset Woods Park, felt like an icebox. The kids bundled up in winter coats for the bus stop at Elm Place School, and Grandma huddled by the fireplace under her favorite quilt. Frustrated by blank dials and stubborn cold, they called DTSOL Appliance Repair & HVAC—and within 20 minutes our technician was at their door. A quick power-down, wire audit, and level backplate installation later, a sleek Wi-Fi thermostat gleamed on the wall. Moments after powering up, the furnace roared to life and warm air filled every room. That's Fast, Friendly, and Local thermostat installation in Highland Park.
