Smith Bros. Heating & Cooling - Green Bay's Expert HVAC Repair

Warning signs include a yellow burner flame (instead of blue), soot around the furnace, excessive moisture on windows, and a stale, stuffy smell. However, CO is odorless and invisible, so the safest approach is an annual professional inspection and tune-up from our certified technicians. We test for leaks, check heat exchangers for cracks, and ensure proper venting to protect your family.

Uneven heating is common in our area due to aging ductwork, poor insulation, or an improperly sized HVAC system. Cold spots often occur in rooms farthest from the furnace or with blocked vents. We perform a comprehensive home comfort evaluation to identify the root cause—whether it's duct balancing, insulation issues, or a system that needs adjustment or replacement—and provide a targeted solution.

Our Green Bay furnace tune-up is a detailed, preventative service designed for our climate. We clean and inspect critical components, check for carbon monoxide leaks, test safety controls, measure airflow, and ensure efficient operation. This proactive maintenance helps prevent mid-winter breakdowns, improves safety, enhances efficiency to lower bills, and extends the life of your heating system.
