What customers are saying
Saved $2,400 vs local contractor
Got quoted $9,200 from a local HVAC contractor for a furnace replacement. Found Furnace Direct and got the exact same Goodman unit for under $5k delivered. My installer couldn't believe the price and installed it in one day. Runs perfectly.
Fast shipping, exactly as described
Ordered on a Tuesday, pallet arrived Friday. Unit was packed well, no damage, all factory sealed. Andrew answered my sizing question over the phone and got me the right model. Couldn't be happier with the purchase.
Installer said same one he'd buy at supply house
My HVAC guy said he pays basically the same price at his wholesale supply house. The markup contractors add is insane. Furnace Direct cut the middleman out entirely. Will recommend to everyone I know.
Heating my 2,200 sq ft home perfectly
Installed my 96% AFUE furnace a couple months ago. Heats my 2,200 sq ft home perfectly, and my gas bill dropped noticeably compared to the old unit. Great product, great price, great experience from start to finish.
Saved enough to pay for the install
Math was simple: 3 contractor quotes all over $8k. Furnace Direct plus local installer was under $5,500 total. Saved enough to basically pay for the install myself. Quality is identical to what contractors charge a fortune for.
No-pressure, honest pricing
Called a few HVAC companies first — every single one wanted to schedule an "in-home consultation" before giving me a price. Furnace Direct just showed me the price. Bought online, shipped next day, done. This is how it should work.
