Dennis Supply Co

Dennis Supply Co operates as a wholesale distributor in Des Moines, Iowa, serving professional HVAC contractors and refrigeration specialists rather than residential homeowners. The business holds a 3.6-star rating derived from eight customer reviews, with operating hours extending from 7:30 AM to 5 PM Monday through Friday. According to their website, the company maintains a 90-year anniversary presence in the industry, offering package units ranging from 2 to 25 tons and distributing products through their corporate office. The Des Moines location at (515) 244-1105 serves as a key supply hub for licensed mechanical contractors throughout the Iowa region seeking equipment and components for commercial and residential HVAC projects.

The wholesaler distinguishes itself through specialized product lines unavailable to general consumers. Their RLS (Rapid Locking Systems) provides UL-listed fittings capable of handling up to 700 psi, designed specifically for joining copper tube in high-pressure HVAC and refrigeration systems. This Rapid Locking technology connects in approximately ten seconds, reducing labor requirements and eliminating the need for nitrogen purging or fire spotter protocols. As an Allied dealer, Dennis Supply offers gas and electric package units spanning the 2-25 ton capacity range, positioning them as a resource for contractors handling larger commercial installations rather than typical residential service calls.

Customer feedback reveals a mixed experience depending on contractor credentials. Positive reviewers describe staff as helpful, with Modern Heating And Air Conditioning praising the team's cutting-edge technology knowledge and customer service. One reviewer specifically references Wayne Dennis in connection with technology and equipment offerings. However, other contractors note limitations in phone service accuracy, requiring physical verification of parts availability. A reviewer named Ryan Reece clarifies that Dennis Supply serves licensed contractors affiliated with mechanical shops, not walk-in retail customers, which explains certain negative feedback from those expecting consumer-facing service.
