I'm in the market for a new heating and air conditioning unit for my home. Most offer variable speed blowers and the more expensive models are equipped with BLDC motors, which seem overkill. I am having a difficult time seeing the advantages to variable speed blowers other than perhaps to reduce noise.
I figure the goal is to heat up the interior as fast as possible by heating the coils as hot as possible and forcing as much air as possible over them. Of course, you don't want to turn your exhausts into hot air guns. Am I missing something here?
