About This Market

UPDATED APR 2026

Residential projects dominate - furnace replacements, AC installs, and ductwork in older housing stock built 1950s-1980s. Costs run 10-15% below Milwaukee rates but above rural Wisconsin due to decent local demand and skilled labor availability. Winter heating emergencies and summer cooling installations drive the bulk of revenue. Getting licensed in Wisconsin means navigating DSPS bureaucracy - plan 6-8 weeks minimum for licensing if you have experience elsewhere. Oshkosh building department runs tight inspections, especially on gas connections. Peak season stretches your crew thin May through September, then heating season keeps you busy October through March. Smart contractors build relationships with local supply houses like Johnson Controls distributors and maintain 24-hour emergency response capability. Insurance requirements hit harder here than rural markets due to liability concerns around industrial accounts.
