Gustave A Larson Company

Gustave A Larson Company supplies HVAC equipment and parts to contractors and homeowners from its Madison, Wisconsin location. The business maintains a 3.5-star rating drawn from 15 customer reviews, operating Monday through Friday from 7 AM to 5 PM with weekend availability limited. Serving Madison and surrounding Wisconsin communities, the supplier offers residential and commercial HVAC equipment, indoor air quality products, refrigeration components, and hydronics or geothermal systems.

The company distinguishes itself through comprehensive product breadth and contractor-focused services. Their inventory includes residential equipment, parts and accessories, commercial HVAC systems, and specialty refrigeration products. They provide online B2B ordering, mobile applications, and cross-reference guides that help technicians identify compatible replacements. The business also offers training resources covering A2L refrigerant transition and SEER2 efficiency standards, keeping contractors current on regulatory changes.

Customer experiences vary significantly according to verified reviews. Wyatt Vanalstine awarded five stars, noting the location reliably provides everything needed for servicing equipment. Modou Gomez gave four stars, calling it a good store with extensive inventory. However, Casey Weaver described ongoing problems with incorrect inventory, parts orders that never materialized, and phone calls redirected to out-of-state branches, resulting in a one-star review.
