Corcoran

We were established in 1983 through Hoffman Estates. Today, the company is run by father-and-son team Tom and John Corcoran, and their nine employees.

While any company can claim to deliver energy-efficient equipment, only the Corcoran Heating and Air Conditioning Team can test, measure, and make the appropriate adjustments to ensure your comfort, safety, and satisfaction. We are trained professionals, certified among the top 1% in the industry, and we serve the greater Chicagoland area with an attention to detail. Our team of employees are held to the highest standards, above municipal codes and sub-standard industry practices.
