Reznor Udap-400 Power Vented Gas Fired Unit Heater - Ng - 316 Stainless Steel Heat Exchanger - 400,000 Btu Review Aug 12, 2016

I have owned this same 400k btu unit for 8 years and it is the best purchase that I have ever made. It is used in a commercial setting and has never had a problem or service call. Reznor quality is second to none and definitely worth the extra cost.

Saved A Lot Of Money Oct 18, 2016

AC unit of 8 years died during heat spell and contractors where quoting very high prices to replace. Having some mechanical ability I decided to purchase and install a new unit myself. eComfort guided me through the whole system and the new unit was shipped to Calif. in just a few days. Had new unit installed in two days and had a licensed AC Tech do my start-up. I saved almost $6000 dollars. New project will be a whole house fan system which they also sell.

Great Replacement. Nov 04, 2016

This replaces the old unit that had given me nineteen years of good service.
