Upgrade to R-8 insulation standards. Keep your conditioned air protected from the extreme attic temperatures of the High Desert.
In Lancaster and Palmdale, attic temperatures can easily exceed 140°F in the summer and drop below freezing in the winter. If your ducts aren't properly insulated, your air loses its energy before it ever reaches your rooms. Working Class HVAC upgrades old, thin insulation to modern R-8 standards, ensuring your comfort isn't lost in the attic.
Old insulation (R-4 or R-6) is simply not enough for the extreme temperature swings of the Antelope Valley.
