When I negotiate with the furnace guy, what about air filters ? Is an electronic worth the dough in consideration of the OZONE produced ? Dont those media type filters like the AIR Bear & AprilAire do a very good job & last a long time ?
Also, although Im pretty much resolved to going with 90+ furnace - I would appreciate any thoughts as to variable speed VS two speed. I would think the variable speed blowers would be less efficient & less reliable b/c of the motor controller ( power conversion not being efficient - Im assuming it is some sort of variable frequency induction motor )
Thanks Guys !
