Not sure if anyone is still following up but the Janitrol product is made by Goodman mfg. Tried contacting them recently due to poor perfomance of their product ( blower motor failure after 12 mos. use) and other parts failures. My problem is that I am incurring costs for labor ( Furnace is warranted for most parts for 5 yrs.) Junkitrol is a good nickname for this equipment that MFG does not really stand behind. Installed at builders suggestion, this 2 yr old piece of junk will cost me more in service charges than a higher priced more reliable one.
