Wholesale Heating Supply Co

Wholesale Heating Supply Co has been a trusted supply hub in Livonia, Michigan for contractors in the heating and cooling trades since its founding. The warehouse holds a 4.7-star average drawn from 20 customer reviews, and the crew behind the counter consistently earns mention for professionalism and product knowledge. Beyond Livonia itself, the operation supports contractors across the Metro Detroit region including Farmington and Farmington Hills, making it a regional anchor for pros who need inventory without delay.

What sets this supplier apart is its commitment to the licensed contractor channel. Every person on staff verifies license status before offering wholesale pricing, a policy that protects both trade professionals and end customers from substandard installations. Manager Bob is called out by name in multiple reviews for going above and beyond, whether that means pulling a special order or making sure the loading dock has a rig ready when a tech rolls in. The warehouse is described as spotless, and orders placed in the morning are often staged for same-day pickup or outbound shipment, a detail that matters when a residential service call runs long and a tech needs a part before five.

Two reviewer stories stand out. Charlie Cassar credits Bob personally with handling a situation that another supplier could not resolve, highlighting the manager's willingness to dig into inventory systems or make a call to a manufacturer rep on the spot. Alyssa Oconnell notes that orders are brought out quickly and that the outbound shipping turnaround is consistently fast, which matters when a commercial job is waiting on a rooftop unit or a heat exchanger. William Minier Jr., who has shopped here for years, describes the crew as over the top in both attitude and execution, a sentiment echoed across reviews that span nearly two decades of patronage.
