    Open Cell Foam Cabinet to improve efficiency of attic AC and Heat Pump

    We are seeking information about the wisdom and cost effectiveness of building an open cell foam cabinet in an existing attic to surround a replacement AC/Heat Pump. The cost of the cabinet is about $ on top of an approximate $ SEER replacement unit. This seems like a pricey add. We were told without the cabinet the best we could achieve would be a 15 SEER unit due to heat in the attic. Does anyone have any experience with this in Texas or the hot south?

    Closed cell foam is much better at controlling temp and moisture.
    Well insulated equipment and ducts will do the job. An insulated closet in the attic is nice but as you see more money.
    Some a going all the way to insulating the entire attic. Expensive but reduces cooling/heating energy.
    We expect real comfort now days. Temp/%RH to a set point, not easy on rainy day and damp evening.
    Keep us posted.

    Provide 60-100 cfm of fresh air when occupied to purge indoor pollutants and keep window dry during cold weather. T-stat setup/setback +8 hrs. saves energy
    Use +Merv 10 air filter. -Don't forget the "Golden Rule"
