Common furnace installation & replacement problems in Oshkosh
- Furnace is 15–20+ years old and needing frequent repairs
- Repair estimate is a large share of replacement cost
- Uneven heating between rooms or floors
- Considering a higher-efficiency condensing furnace
- Adding central air at the same time
A replacement furnace should be sized with a load calculation (ACCA Manual J), not just matched to the old unit's size. Ask any contractor you talk to whether they do one. Utility and federal incentives change often; ask the installer what currently applies and confirm with Focus on Energy or your utility.
Oshkosh requires a permit for heating and air-conditioning work, though window-mounted air-conditioning units don't need one.
Work can't start until the permit is issued and paid.
