David Loberg Northeast Nebraska | Are you going full heat? Or heat/cool in dryer? We utilized our air return til we put an air system to a cooling bin, then took it all off and went to full heat, sped up our bph drastically. And Id go centrifugal. We had an axial fan driall, then went to a centtrifugal superb. Noise may not be an issue being by a house, but just working around or on the thing its so nice to not to have to walk 40 ft away before you can talk to someone. |
