How are high-efficiency furnaces inspected in Woodbury homes?

Most Woodbury homes have a forced-air gas furnace, and homes from the 1990s and 2000s often have high-efficiency condensing units that vent through white PVC pipe rather than a metal chimney. The inspector confirms the furnace runs and produces heat, checks its approximate age and maintenance history, inspects the PVC intake and exhaust venting for proper slope, support, and termination clearances, and looks for blocked or improperly pitched condensate drainage, a common issue that can shut a furnace down or cause leaks. They'll also note dirty filters, signs of rust or corrosion, and combustion safety concerns. On older mid-efficiency furnaces vented into a chimney, the inspector watches for backdrafting and a cracked heat exchanger, which can leak carbon monoxide, though confirming a hidden crack requires an HVAC technician. Given Minnesota's long heating season, a furnace nearing the end of its life, typically 15 to 20-plus years, is an important budgeting and negotiation point.
