Furnace ignition failure during Wisconsin winters is often caused by a dirty flame sensor, a faulty igniter, or issues with the gas valve. These components can be stressed by the extreme cold and increased demand. Our technicians can quickly diagnose and clean or replace the faulty part to restore safe, reliable heat to your home.

Yes, frozen heat pump components are a common issue here, especially during periods of high humidity followed by freezing temperatures. First, turn the system to 'emergency heat' or 'off' to prevent damage. Don't try to chip the ice off. Call us. The cause is often a refrigerant leak, a dirty coil, or a failing defrost control, which our experts can repair to get your system running efficiently again.

Preventative maintenance is key. Before winter, we recommend a professional tune-up that includes cleaning the flame sensor and burners, checking the igniter, testing safety controls, and inspecting the heat pump coil and defrost cycle. This proactive service helps catch small problems before they lead to a no-heat emergency during a Racine cold spell.
