My Honeywell 20x25x5" Fc100 filter has been in place since 6/18/04 when the system was installed. It does have dirt on it but I am not sure if it needs to be replaced?? They told me 1 yr on these filters?

I agree with you about getting it fixed now. I have the service manager coming to my house on Thurs to see the install. I just want to get as much info from you guys so I can make better suggestions

I am problably missing something but I was thinking why not replace the 6" flex with 8" flex that should increase air flow to the upstairs and reduce ESP?

I wish you guys were local then this would have never happened. If you ever decide to move to Southern CA I think you could make millions!!
