A furnace replacement in Coon Rapids runs $4,500–$9,500 installed with us, sized by Manual J and put in writing at a flat rate. Open basements keep the swap predictable; the water heater left in the chimney is the part that takes judgment.
Coon Rapids furnace replacements are about as predictable as they get. The basement is open, the trunk-line ducts are simple, and an outside wall is usually close for the PVC intake and exhaust a 96–98% furnace needs. The part that takes judgment is the water heater. Once the furnace leaves the masonry chimney, a gas water heater vents alone into a flue sized for two, and it may need a liner or a switch to power-vent. We quote that with the furnace.
Sizing gets a Manual J because these houses have usually gained insulation and windows since the last furnace. A mechanical permit is normally required, and the written quote lists any liner or power-vent water heater as its own line.

It's worth pricing, since these duct systems usually handle a heat pump with little rework. The heat pump replaces the AC outside, and the new furnace becomes backup for deep cold. Ask about it during the furnace quote and we'll size both from one Manual J.
Yes, and it's the easiest time to do it, with the plenum and wiring already open. A bypass or flow-through humidifier mounts on the furnace and needs a water line and a drain, both usually close by in a Coon Rapids basement. Set its humidistat lower as it gets colder outside, around 25–35% in cold weather and less in deep cold, to keep the windows dry. Our indoor air quality equipment runs $350–$2,800 installed.
