Reviews from St. Charles
“Furnace short cycling all winter — turned out to be an oversized unit and a bad limit switch. They fixed the switch and adjusted the blower, problem gone.”
— Greg H., St. Charles, MN“AC quit on a 94-degree Saturday. Called at 10, tech was here by 1, capacitor swapped and cold air by 1:30. Price matched the quote exactly.”
— Dana R., St. Charles, MN“Honest people. The tech explained every option, showed me the failed part, and didn't push anything I didn't need.”
