Most people assume you have to buy a furnace through a local HVAC contractor — the same company that installs it. That assumption costs Minnesota homeowners $400–$1,200 on a typical furnace replacement. Here's how factory-direct HVAC actually works and why it's completely legitimate.
The Traditional Model (and Where the Markup Comes From)
In the traditional HVAC model, the chain is: Manufacturer → Distributor → HVAC Contractor → You. Each step adds margin. By the time a Goodman furnace that left the factory for $600 reaches your home through a local contractor, it's priced at $1,200–$1,800 on your invoice — even before labor. The contractor's equipment markup of 30–50% is a standard part of their business model.
Buy the same name-brand furnace the pros install — shipped factory-direct to your door. No middleman, free delivery, 5-star rated, and financing available.
How Factory-Direct Works
The factory-direct model shortens the chain to: Manufacturer → Authorized Factory-Direct Retailer → You. You buy the furnace directly, it ships to your home, and your licensed HVAC contractor installs it. The contractor charges for their labor — which is fair — but you've already bought the equipment at near-wholesale pricing.
Is This Legal? Does It Void the Warranty?
Yes, it's completely legal. There's no law requiring you to buy HVAC equipment from the installing contractor. Goodman's warranty is fully valid when the unit is installed by a licensed HVAC contractor and registered within 60 days of installation at goodmanmfg.com. The warranty does not require the equipment was purchased through the installing contractor.
What to Tell Your HVAC Contractor
Most professional contractors are fine installing customer-supplied equipment. Simply say: "I'd like a quote for labor-only installation of a Goodman [model number] I'm purchasing directly." Give them the exact model number so they can confirm it's appropriate for your home. A small number of contractors won't install customer-supplied equipment — that's their right. There are plenty of licensed techs across Minnesota who are happy to do labor-only installs.

What to Watch Out For
