Customer Testimonials

Gas Furnace Maintenance in Grayslake, IL 60030

“Our technician (Josh was his name I believe) was very friendly, explained what he was doing, and kept our house clean (putting on shoes covers and cleaning up any mess he made). We have used Miller’s Area Heating since we moved into our home in Jan 2020. I have always been impressed at the technical excellence and superb customer service. I highly recommend Miller’s to anybody who needs an HVAC company.” – Hank D.

Thermostat Replacement in Antioch, IL 60002

“The technician seemed to do an efficient job of replacing and configuring the new thermostat. He patiently helped us through connecting it with our home network, and cleaned up after himself. Our only dissatisfaction is with Trane: the new thermostat doesn’t have a new warranty and that the scheduling software is confusing and clumsy. We’re quite satisfied with Miller’s service.”
