    Thanks for answering my questions.

    So, it seems your system is able to deliver on capacity in both heating and cooling modes when there are no component or functional issues with the system. Is that correct?

    Now, another question. Did Unico make your entire system, or just the air handlers? Is the heat pump/chiller itself made by Unico, or others? Is this system a high velocity duct arrangement, with small ducts and outlets?
    • Electricity makes refrigeration happen.
    • Refrigeration makes the HVAC psychrometric process happen.
    • HVAC pyschrometrics is what makes indoor human comfort happen...IF the ducts AND the building envelope cooperate.


    A building is NOT beautiful unless it is also comfortable.

    All Unico system

    Yes, this is a Unico Unichiller, all unico parts including the high velocity 2 inch ductwork/outlets.

    I talked to Mitchell, our second HVAC guy tonight, and he said the 5 Ton unit is certainly NOT oversized, and that the Unico rep he talked to said it might be okay to add the basement to the system, if all zones weren't demanding a lot of cooling at once. Basement temp with no conditioning, after a 95 degree day (and weeks) is 79 (our kitchen was 87 at 6:00pm with no AC).

    the photos by the way, are of the southeast, and west exposure.
