    Yes, it's an inverter unit. When the unit is in cooling mode, when could it possibly want less airflow (this is not a "true" office space - only a "home office", i.e., it will not be run when ambient...
  6. I don't think so. Having the fan blow ambient air...

    I don't think so. Having the fan blow ambient air directly at the heat pump will ensure that the heat pump will always have the coolest air possible. Remember, I technically don't care about the...

    Yes, I explained that there would have to be an exhaust fan that would be wired to operate whenever the compressor was running - he was fine with that. I'm currently playing phone-tag w/ an engineer...

    I realize this. Hence why I said I'm trying to determine how many "CFM" or "Air Changes per Hour" I will need to provide via "mechanical assistance". I only mentioned louvers when describing what the...

    No, they want cooling. I think you missed the point...unless the heat pump was in the SAME ROOM as the evaporator, I think that the fact that the heat pump rejects more heat than the evaporator...

    Is it really that hard/difficult to believe/understand that a homeowner wouldn't/doesn't want to see/view a condensing unit/heat pump outside, but can/does want to see/view a couple...

    This actually isn't for me, its for a home owner I'm providing a quote for. The builder I'm working with asked me to preditct what kind of cost savings they'd see from my proposal to change out their...
