Illinois HVAC businesses, anchored by the Chicago metro, have a solid M&A environment. The four-season climate creates both heating and cooling demand, supporting year-round maintenance agreements. Chicago has one of the largest pools of HVAC buyers in the Midwest.

Illinois HVAC Multiple Benchmarks

Illinois HVAC businesses sell for 2.5x–4.5x SDE. The Chicago metro has the deepest buyer pool and most competitive multiples. Suburban Chicago HVAC businesses with maintenance agreements regularly see 3.5x–4.5x. Downstate Illinois markets (Peoria, Springfield, Rockford) sell at 2.5x–3.5x SDE.

Four-Season Climate Dynamics

Chicago's climate creates balanced HVAC demand: intense summer cooling and real winters requiring heating maintenance. This natural motivation supports dual-system maintenance agreements covering both AC and furnace tune-ups annually.

PE Activity in Chicago HVAC

Multiple PE-backed HVAC platforms include Chicago in their expansion plans. Regional Midwest operators are active acquirers. Individual/SBA buyers dominate for businesses under $2M revenue, with PE relevant at $500K+ EBITDA. Competitive processes in Chicago routinely generate 3–5 qualified buyers for quality businesses.

Illinois State Income Tax

Illinois flat 4.95% income tax applies to capital gains. Combined with federal 23.8%, sellers pay approximately 28.8% effective rate. On a $2M gain, that's $99K in Illinois state tax — moderate relative to California or New York.
