3/ if you are using a pleated filter you have likely killed 25 to 40% of your airflow coming from the furnace..this is especially true of 3M filters. These filters are raising your utility bills by 30% GUARANTEED..... it takes twice as long to heat ANY home using pleated filters this raising your GAS and ELECTRIC bills.

Check these things and if none of these steps improve the situation then I can come and investigate further .

1 other thing...who was your builder???...this will help me immensely because with this information I can tell you without a doubt whether you need a cleaning and inspection.
A good builder would have had the furnace and ducts cleaned pre occupancy for you and would have used a reputable furnace company. One word of caution however...all cleaning companies ARE NOT the same ...if you want it done right you need me and me only.

Hi,

Kind of along the same lines as Wooksters question - I have a few vents that radiate very little heat, and some (closest to the furnace room) that have a higher flow rate. I've checked the dampers, and they're all open. Just wondering if all vents should have the same air flow, or will there just be some that won't? What would be the possibility of duct work being loose within the ceilings/floors, and is there a way to tell? By the way, the house is nearly 20 years old. Thanks.

With respect to the furnace filters - what would you recommend aside from the pleated (those are all I have ever seen, at the big box stores). Also I have heard of some people taping over the area where the filter plugs in to prevent losses. Is this recommended?
