Express Heating and Cooling LLC - Milwaukee's Top-Rated HVAC Repair

Key warning signs include a yellow burner flame instead of blue, soot or rust around the furnace, excessive moisture on windows, and persistent, unexplained flu-like symptoms in your household. If you suspect a leak, leave your home immediately and call us. We provide emergency CO leak detection and repair to keep Milwaukee families safe.

Absolutely. In our Milwaukee winters, leaky ducts can force your furnace to work up to 30% harder, wasting significant energy and money. We perform comprehensive duct assessments and use professional sealing methods to contain the warm air, improve system efficiency, and deliver consistent comfort to every room in your home.

We recommend an annual furnace tune-up, ideally in the fall before the heating season. This proactive maintenance checks for CO leaks, ensures efficient operation, and catches small issues before they become major, costly repairs. It's the best way to ensure reliable, safe heat through a Wisconsin winter.
