Customers Say
Across multiple installations, Reznor unit heaters in sizes from 45,000 to 150,000 BTU heated spaces such as a 950 sq ft garage (35°F to 70°F in 15–20 minutes), a 60x40x16 shop (58°F to 70°F in 35 minutes), a 46x60 shop with 16 ft ceilings, and even a 35,000 cubic foot shop kept at 60°F in -11°F weather, with one unit running flawlessly for three seasons. Installation was frequently described as straightforward—sometimes taking about four hours or reusing existing mounts—with reports of quiet operation and easy replacements of older Reznor models lasting nearly 20 years, though isolated issues included an incorrect conversion kit and one poor delivery experience.

- Reznor 60K BTUHVAC Direct delivered on time and unit was incredibly packaged for freight. The unit itself is performing quite well in an uninsulated garage. Keeps everything from freezing. I could not be happier with this purchase and my purchase experience. I will definitely purchase from HVAC Direct when its time to heat my 30x40 barn.

- Fast delivery, great price, excellent packaging with zero damage. Easy to install.Ordered to replace an old UDAP 45. Basically the same but taller. Fit fine as a hanging unit in the garage. Quieter and warmer output than the old one. Pretty much just unhooked the old one, unmounted it and mounted the new one with the same bolts, reattached connections with a slight modification to the venting. Free shipping and it still got here in less than a week. Overall, great experience with HVACDirect and the price was the lowest I could find.
