Our house is 4 years old and we've been frustrated by rooms further away from the HVAC unit are cold in the winter and hot in the summer. There's barely and air coming out of the vents in those rooms.
A technician was doing a spring check-up on the system and said the out-take vent was too small for the amount of air the system was trying to blow through it, (it takes a standard 16x25x1 filter). He said we basically have the largest system you can have in a residential house and we probably should have had 2 systems rather than one. He suggested installing an Aprilaire 2200 air cleaner system which would allow more air to flow and increase the circulation throughout the house. He said the rooms which had little airflow would be dramatically better.
Does this sound reasonable? The filter size on the 2200 looks to be only a few inches bigger than my current filter size...would this be enough to cause "dramatic air circulation improvement?"
