George and Son's HVAC Inc.

George and Son's HVAC Inc. was founded in 1972, making it one of the longest-running heating and cooling contractors in DuPage County. The company holds a 4.7-star rating from 56 verified customer reviews, reflecting decades of consistent service in Darien and surrounding communities including West Chicago, Yorkville, and Oswego. As a three-generation family business, they have maintained their reputation by offering both residential and light commercial HVAC solutions, with technicians who understand the specific demands of northern Illinois winters and humid summer peaks.

What distinguishes George and Son's from newer competitors is their commitment to comprehensive indoor comfort solutions beyond basic heating and cooling. They install and service hybrid heating systems, which combine heat pump technology with traditional furnaces for improved efficiency during shoulder seasons. Their indoor air quality offerings include humidifiers and smart thermostat integration, helping homeowners manage both temperature and moisture levels year-round. The company maintains 24-hour availability, understanding that HVAC failures do not follow a 9-to-5 schedule.

Recent customer reviews highlight specific technicians who have earned repeat business. For water heater replacements during the holiday season, technicians Ed and Rocco completed both the tank installation and complex piping modifications within a single appointment. In July 2025, a Darien homeowner engaged Nick, Rocco, and Brad for a three-day project replacing the air conditioner, furnace, and water heater. Owner George stopped by daily to ensure quality control, demonstrating the hands-on approach that distinguishes family-owned operations.
