About This Market
Aurora's HVAC market runs hot with steady residential replacement demand and growing commercial work from the city's expansion along the Fox River corridor. Competition is moderate with approximately 4,147 licensed establishments statewide, but the western Chicago suburbs see consistent year-round work. Older housing stock drives furnace and AC replacements, while new construction feeds ductwork and complete system installs. Costs track 10-15% below Chicago proper but above rural Illinois rates due to material transport and skilled labor availability.
To work Aurora effectively, get your Illinois Air Conditioning Contractor License locked down first - the exam isn't a joke and covers real technical ground. The city's mechanical permit process is straightforward but don't skip it, inspectors know their stuff and will call out shoddy work. Build relationships with local supply houses early since material costs make or break your margins. Peak season runs long here - May through September for cooling, then straight into heating season through February. Plan your cash flow accordingly and keep emergency service capability if you want the premium rates.
