Serava.AI has mapped 1,093 acquisition-ready HVAC businesses in Illinois.

Revenue for HVAC businesses in Illinois varies by size, but most SMB-scale targets in our database fall in the $1M to $15M annual revenue range. Serava.AI provides revenue estimates benchmarked from payroll data, OSM business data, and SBA loan records. Businesses in this market average 7 years in business (among those with a known founding date).
Key signals for a high-quality HVAC acquisition include: a long operating history (15+ years in business), stable recurring or repeat revenue, strong online ratings (4.0+ with 20+ reviews), an established local customer base, and a skilled technical workforce. Serava.AI's Acquisition Fit Score (0 to 100) weighs all of these factors and benchmarks each company against your specific buyer criteria.

Businesses with recurring contracts, a long operating history, and clean books command higher multiples.
