The best time to find a furnace problem is before the first stretch of bitter weather. Mr. Holland’s provides furnace maintenance in Milwaukee and throughout Southeastern Wisconsin to help homeowners prepare their heating systems for months of steady operation. A furnace tune-up gives our technicians an opportunity to watch the complete heating cycle and identify anything that isn’t working as intended. We’ll check the thermostat, filter, ignition system, burners, flame sensor, blower, electrical connections, safety controls, venting, and condensate drainage. We also clean accessible components, look for signs of wear, and test the furnace after the work is complete. If we find something that needs attention, we’ll show you the issue and review the available repair options before completing additional work.
