Clean Air Doctors | Insulation Company | Spray Foam Insulation

Clean Air Doctors operates as a specialized insulation contractor serving the Chicago metropolitan area from its local headquarters. Founded by Ofer Tsemah after observing consistent poor workmanship across the region, the company has built its reputation on thorough assessments and complete job execution. Currently holding a 4.8-star rating from 109 customer reviews, the business has completed over 1000 major projects and served more than 2500 homeowners. The service area spans 16 Chicagoland communities including Naperville, Hinsdale, Oak Brook, Glen Ellyn, Aurora, Joliet, Elgin, Schaumburg, Arlington Heights, Downers Grove, Elmhurst, Wheaton, Bolingbrook, Palatine, and Evanston. Operating hours run Monday through Saturday from 8 AM to 8 PM, providing flexible scheduling for residential and commercial clients seeking air quality and insulation solutions.

What distinguishes Clean Air Doctors from typical insulation contractors is their commitment to honest assessment before any work begins. The company evaluates each home based on actual needs rather than revenue potential, refusing to recommend unnecessary services. They offer both open-cell and closed-cell spray foam insulation, selecting the appropriate type based on the specific area application, closed cell for moisture-prone crawl spaces and exterior walls, open cell for interior walls and attics requiring flexibility. The business also handles related services including whole house humidifier installation for Chicago's notoriously dry winters and UV light air purification systems that neutralize airborne contaminants before circulation. Every job follows the same standard: complete execution, clean work areas, and clear communication about what was done and why.

Customer experiences reveal the hands-on approach that defines this company's service. For one homeowner, the team addressed chronic temperature issues above the garage by blowing in approximately 12 inches of insulation and sealing all recessed lights and fans, a problem the customer had endured through multiple Chicago winters. Another reviewer highlighted the team's willingness to tackle a challenging dryer vent located in a tight space, going above and beyond by taping seams to prevent future lint accumulation. A third customer specifically praised the honest approach: after receiving a free estimate, they were told directly what work was genuinely needed rather than being pressured into unnecessary services. The spray foam installation for interior walls was completed at what the reviewer characterized as a reasonable price compared to other Chicagoland bids.
