in the spirit of trying to create less threads. quick question for the HVAC pros.
the outside unit listed above sits below a set of deck stairs giving it very little room to "breath". the hot air pushed out is essentially in a enclosed area so could this be a factor as to why my ac unit can't cool the house?
Huge factor. Your 1.5 ton could be working as a 1 ton or less. There's supposed to be 4 foot minimum of free air space over the unit and 3 foot from sides. Side closest to the house can be 1' away though. Inside and out it's all about air flow.
