Buchner Heating, Air & Plumbing

Buchner Heating, Air & Plumbing has kept Chicagoland homes comfortable since 1919, making it one of the oldest continuously operated contractors in the region. The company holds Illinois HVAC license #IL58-143520 and maintains offices at 2116 West Galena Blvd. in Aurora and 115 E. Ogden Ave. in Naperville. With a 4.9-star average across 453 reviews, Buchner serves the entire Fox Valley and western suburban corridor, providing 24-hour emergency service seven days a week for heating, cooling, and plumbing emergencies. Homeowners in Aurora, Naperville, and neighboring communities can reach the office at (630) 896-4600.

What distinguishes Buchner is its ability to handle multiple home systems through a single service call. As a Carrier dealer, the company installs and services one of the industry's most recognized furnace and air conditioning brands. Beyond traditional HVAC, Buchner also addresses indoor air quality concerns and maintains a full-service plumbing division, allowing customers to resolve heating, cooling, and plumbing issues with one trusted provider. The company offers financing options for new equipment purchases and provides a $20 discount for first-time service calls booked through their website.

Named technicians appear frequently in customer reviews, suggesting stability in the service team. One reviewer, Adam Thomas, described how technician Keith drove to Indiana on a Friday evening to source a gas valve part unavailable locally, then returned Monday morning to complete the installation. When a second visit was needed the following day due to a minor leak, Keith arrived at 6:30 a.m. to resolve it. Another customer, Dmitry Zat, praised installation crew members Sean, Mark, and Cory for handling a complex Carrier furnace and air conditioning install that required plumbing modifications and custom metal work, describing the team as having "over-delivered on all their promises."
