furnace vent vs. intake location
My Carrier HVAC unit was installed by a local factory authorized company 6 years ago. I recently realized that they installed the sidewall exhaust vent 12" below the intake. Everything I can find in the manual (and common sense) tells me this is wrong as the exhaust will rise directly up into the intake. Is this ever correct? Should I expect my unit to fail prematurely from corrosion? If that is the case should I expect the company to remedy this and adjust the warranty?
My second question (which led me to discover this) is that I need to relocate the AC outside unit so I can build a deck. The best place for it is right in front of the furnace vent. Is this OK as long as I cover the unit during the heating season to prevent the furnace exhaust from corroding it?
