Unit Woks Great But Concerned About The Lack Of Warranty Aug 01, 2016

It was easy to install and start up but in reading the manual no warranty is supplied unless the system is installed by a certified installer.

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

I used this inline fan to hook up to my vent hood in my kitchen.

Great Product Aug 01, 2016

Works great, much quieter than my last gable fan, and moves a lot more air. Only concern is the thermostat that came with this unit ranges 65 to 90. My last fan was 85 to 145. Unit seems to stay on longer in order to reach the 90 degree. Unit runs more being in an attic in Florida. This fan was very easy to install and had great wiring instructions.

I have had it installed about a month now and I think it was a great purchase. A little expensive, but if it last as long as my last one, I'll be happy.
