Questions
Is AlorAir or AprilAire better for a crawl space?
It depends on the setup. AlorAir’s certified models are portables: they stand in the space, without ducts. AprilAire’s are whole-house units, installed on ducts, often by a contractor. For one sealed crawl space, size a portable with the calculator first.
