Previously, I posted as to which one is better and I have decided on the Infinity ICS based on the responses. Now, the installation will be tomorrow (3/31/09) and the dealer asked me if I wanted the 5 year old Honeywell humidifier on the old furnace, installed on the NEW one. The humidifier IS NOT WORKING because copper tubing clogged-up with water scales one year after we took possession of the house and I have decided to use a portable one which is working fine so far. I indicated to him that I,ll just keep it aside and decide later on if I want it re-installed. The question here is: Is it a wise decision on my part?
