A furnace going into a Todd County home is not going into a mild environment. 101 severe weather events were recorded in Todd County, Minnesota between 2015 and 2024. At that rate, severe weather is a standing condition, not an occasional interruption, and a contractor who treats it otherwise will size and spec the unit for a place this county is not. What the ductwork can handle, where the unit sits, and how the system is sealed all carry more weight here than they would in a quieter area. A contractor working a Todd County installation prices those decisions into the job before anything gets ordered.
Ductwork laid down for an earlier generation of furnaces was sized and routed for what was available then, and a new unit draws and distributes air on different terms. Half the homes in Todd County, Minnesota were built in 1975 or earlier (2020-2024 ACS 5-year). That gap between the building and the equipment running in it now is where a furnace installation gets complicated: a contractor opening walls and crawlspaces here is checking whether the existing duct system can carry what the new furnace delivers, not just whether the furnace itself fits the space. Electrical service gets the same look. If the ductwork cannot handle the load, that work gets priced and scoped before the new unit is ever ordered.
What Gets Installed With a New Furnace
The furnace itself sits in the basement, utility room, or mechanical closet and is the unit that produces heat for the house. Attached to it is the flue pipe, which runs up through the house or out through a wall and carries combustion gases outside. The air handler, sometimes built into the furnace cabinet, moves conditioned air into the duct system.
The thermostat mounts on an interior wall and is the control point a homeowner touches every day. The filter housing sits where return air enters the furnace, and a new installation includes a correctly sized filter rack matched to the unit. The condensate drain line runs from the furnace to a floor drain or utility sink when a high-efficiency unit is part of the install.
The drawing shows a typical layout, and a licensed contractor determines exactly which components apply to your house and how they come together.

Licensing Rules for HVAC Work in Todd County, Minnesota
Minnesota defines a mechanical contractor as a business that installs, repairs or maintains heating, ventilating, cooling or refrigeration systems — the definition that carries the exemption from the residential contractor licence.
Minnesota's residential contractor licence does not reach HVAC work: the licensing section carries its own exemption list, and a mechanical contractor is exempt from the licence requirement by name.
Severe Weather Events in Todd County
Minnesota winters put sustained pressure on heating equipment, and the weather Todd County sees over time shapes how hard a furnace has to work and how often. That workload is a local variable, and it is part of what a contractor here accounts for when sizing and installing equipment.
