HVAC Services Mukwonago WI | Call Donovan & Jorgenson

This is a common winter issue in our climate. First, check your thermostat settings and ensure the furnace's power switch is on. If it still won't ignite, it's best to call for service. Our technicians are experienced with the ignition and sensor problems that frequently occur during Wisconsin winters. We offer 24/7 emergency repair to diagnose the issue—often a dirty flame sensor or faulty ignitor—and get your heat restored quickly and safely.

Regular maintenance is key to system longevity, efficiency, and preventing major breakdowns. Our thorough maintenance checks include cleaning critical components, checking refrigerant levels, testing safety controls, and ensuring all parts are functioning properly. For our Mukwonago customers, this proactive service is especially important to catch minor issues—like early signs of a refrigerant leak or a furnace ignition problem—before they become costly emergencies, particularly during peak heating and cooling seasons.

Our employee-owned structure means every technician and team member has a direct stake in the company's success and your satisfaction. This fosters a high level of personal accountability and pride in our work. You'll notice it in the detailed communication, the care taken during installations, and the commitment to finding the right solution for your home. Our team is invested in the long-term performance of your system and in building lasting relationships within the Mukwonago community.
