  1. We used to have an Apollo system upstairs as well as one in the improved basement. Original housing developer (long since gone under) ripped through the neighborhood apparently installing the units as cost saving measure. Was able to replace the upstairs with a gas unit 5 years ago (can't downstairs) but before upstairs was replaced we used got to get this annoying sound coming from the system whenever it kicked on during the winter.
