Furnace Replacement in Lester Prairie, MN

Furnace replacements in Lester Prairie homes
In Lester Prairie, a furnace replacement often comes with a second question: add central air at the same time? Many older houses in town still cool with window units, and when the old furnace comes out, a coil can go on the new one and a condenser outside, provided the ducts can carry cooling airflow. We check static pressure and add a return where the old layout needs one.
The 1990s mid-efficiency furnaces here usually vent into a chimney or metal flue. Staying at 80% means confirming the flue is sized right, often with a liner; moving to 96–98% means PVC out a side wall, a condensate drain and a fix for the water heater left behind. Newer homes at the edge of town already vent in PVC. On farms and acreage, propane furnaces get the LP conversion. Gas rebates in town depend on the company named on your gas bill.
A replacement normally needs a mechanical permit from the city, or from the county or state for farms outside city limits.

Furnace replacement in Lester Prairie: questions
Can the propane unit heater in our shop near Lester Prairie be replaced with the house furnace?
Yes, in the same project if you like. Unit heaters need their own gas line, venting and clearances from stored fuel and equipment, so they are priced as a separate line. We check the shop's size and insulation before recommending a size, since an uninsulated shop with big doors needs far more heat than a sealed one.
Our farmhouse near Lester Prairie runs on propane. What should a new furnace quote include?
An LP conversion kit on the furnace, at the same price range as natural gas. Most furnaces ship for natural gas and are converted to LP with the manufacturer's kit, and the price range is the same. Because propane usually costs more per unit of heat, a 96–98% furnace tends to pay back faster than in a gas home. On McLeod Cooperative Power, a cold-climate heat pump paired with the furnace is worth pricing too, since it can cut propane use.
