1137 21.3 GPD Drain Type Fan Power Humidifier (120v)

I looked for at least 3 most before deciding to purchase this G.A Humidifier! One of the main issues I have is with a horizontal Carrier Infinity Heat Pump air handler in my attic. It is up only 12in blocks and did not have enough room on the supply side to be able to adequately drain a unit and service the filter once a year. Second issue is with a 5 stage variable unit, you cannot use a bypass setup as this would mess with the feed plenum static press sensor that backs the blower down when the static A.P. gets too high, A fan humidifier is the ONLY option for this type of HVAC setup. I called Supply House to work thru my options of fan powered units. They were GREAT as always and I settled on G.A. based on the other reviews I had seen here. I go the unit very fast, S.H. ROCKS! I decided that I needed to install this on the return side for accessibility reasons and called the General Aire 800 number. Had to leave a voicemail and wondered if I would ever get a call back. D@MN if I did not get a call back in 15 mins and has a VERY knowledgeable support person that answered all fo my questions about installing this on the return side, registering it and making sure the warranty would still be valid. Also confirmed that I needed to install isolation relay as the "HUM" terminal on Infinity systems feeds 24vac and needed to use the yellow wires on the other side of the relay. This will allow the Carrier communicating thermostat to control the humidity in the house and protect my windows when it gets really cold here in NC. Ended up installing on the return side with a hot water feed and all seems to have worked out well. Have some warn humid days now, but will look forward to not having to fill a console humidifier everyday in the winter. Bottom line: You cannot go wrong with Supply House and General Aire customer service are AWESOME and helped inn every way possible to make this a successful instal project in my house. Thanks and keep up the great wor

I have used this product, but found it to defective in the cabinet I am a tech have been one for over 40 years also a commercial heating and air business owner. I brought this unit for my home as a replacement for the one that quit working, I did get good service from it. I went down to my basement one morning and found that the unit had broken away from the furnace onto the floor exposing the furnace plenum, thank goodness igo to the basement daily. Could have been a very bad situation. (Carbon monoxide, or even an electrical fire.)
