I'm looking for a maker of a side-exhaust condenser in the 3-4 ton range. I want to locate the unit under a deck where a top-exhaust unit would not be appropriate. My installer mentioned Trane, but didn't have details. On the Trane website, I've been unable to find any side-exhaust units. In fact, I've checked the websites of other makes (Carrier, etc. and not found any side-exhaust units anywhere. Any pointers would be appreciated.
