What Makes Illinois Unique
The Chicago metro is one of the largest trade service markets in the Midwest. The city's dense population, older housing stock, and extreme weather create year-round demand for HVAC, plumbing, and electrical services.
Chicago's licensing requirements are among the strictest in the country, especially for plumbing and electrical work. Companies with active city licenses are more valuable because the licenses are difficult to obtain.
The western suburbs (Naperville, Aurora, Joliet) are a sweet spot for trade service companies: high household incomes, newer housing that still needs maintenance, and a growing population.
Illinois has harsh winters that drive strong furnace, boiler, and snow-related service demand. HVAC companies that also offer indoor air quality and duct cleaning services generate higher revenue per customer.
PE platforms are building trade service groups in the Chicago suburbs, often starting with HVAC and adding plumbing and electrical through follow-on acquisitions.

How to Sell Your Service Business in Illinois
1. Get a Current Valuation
Before anything else, know your number. Your business's value is based on how much profit it makes in a year - after you add back things like your personal salary and expenses that a new owner wouldn't have. That adjusted profit (called SDE) gets multiplied by 1.7x - 3.3x to get your value.
Our free valuation calculator gives you a range in about 2 minutes - no email required, no strings attached. It factors in your revenue, profit, technician count, recurring contracts, and Illinois-specific market conditions.
2. Understand Illinois's Licensing Requirements
Illinois does not have a statewide general contractor license, but Chicago and many suburbs require contractor licensing. Plumbing is licensed statewide, while HVAC and electrical licensing requirements vary by municipality.
If you're selling to a private equity group or regional operator, your attorney should be familiar with Illinois's specific requirements for contractor license transfers, trade licenses, and insurance continuity during the sale.
3. Prepare Your Business for Market
Buyers - whether PE platforms or individual operators - look at the same fundamentals:
- Clean financials - 3 years of tax returns and profit & loss statements
- Recurring revenue - maintenance contracts, service agreements, and membership plans
- Technician team - how many techs you have, their certifications, and whether they will stay after the sale
- Fleet and equipment - condition of trucks, tools, and inventory
- Owner dependency - businesses that run without the owner in the truck every day are worth more
- License transferability - contractor and trade licenses that can transfer to the buyer or survive a change of ownership
