About to install my 3.5 ton HP with 4 ton VS blower. I want to add a humidifier and can't seem to get the same answers. Contractor quoted both an undermount flow through, powered and a Honeywell Trusteam. He said the Truesteam is the best but the cost and monthly maintenace seems a little high.
I am interested in the Aprilaire line. Is the powered 700a recommended over the 600a for a HP or does it not make one bit of difference. Thanks
