Koch Air LLC

Koch Air LLC operates as a HVAC distribution service based in Evansville, Indiana, serving contractors and dealers across the Midwest from 11 branch locations. With 80 years of industry experience as a Carrier distributor, the company supplies residential and commercial HVAC equipment along with parts and supplies to professional contractors. The Evansville location sits at 1900 W Lloyd Expressway and is open Monday through Friday from 7:30 AM to 5 PM. Google reviews show a rating of 4.4 stars from 16 reviews, with customers frequently praising the parts department and helpful staff.

What distinguishes Koch Air is their multi-million dollar inventory and their role as a contractor-only distributor. They stock Carrier equipment, chiller systems, VRF systems, and Carrier EcoBlue rooftop units, offering same-day parts pickup for dealers who need components quickly. Their ISO 9001 certification reflects consistent quality management practices. The company runs a dealer loyalty program with incentives and handles commercial proposal requests for architects and engineers working on larger builds. They also provide technical support and training so dealers can stay current on new HVAC technology.

Reviewers mention specific positive experiences. Greg Haller purchased a new furnace and air conditioner through a dealer and received a competitive price. Zach R and Jon House both describe the parts shop as places where they never leave empty-handed. Jon Fast explicitly notes the operation sells to contractors only, which aligns with the distribution model. Adam Matheson flagged that receiving closes for lunch from 12 to 12:30 PM, useful timing for will-call pickups.
