Installed By Retired Pipefitter, Local #597 Chicago, Il. Oct 01, 2016

I was very impressed with the units that Goodman sells. I purchased the efficient 96% unit. I installed it Feb. 27th in my garage and it replaced a 20 yr. old Carrier unit which was only 80% efficient. Of all the many units that I installed while working, I have never seen any unit built as well and strong as this Goodman unit and it works well. I'm happy to give this testimonial.

Have used Runtal UF series before and the quality is excellent. Now if they could sneak more BTUs per foot.

Even if the motor was replaced under warranty, it would still be the same noisy motor. If you want to be able to talk in the vicinity... more
