The location of an outdoor Goodman unit relative to the building wall is significant. The unit shown on page 7 of the Heat Pump Product Brochure published by American Standard ퟀ�,® Heating & Air Conditioning is placed close to the center of your house wall, like a musician of the Symphony Orchestra playing a concerto. Shells and walls constructed from hard material are used behind a sound source if passive sound amplification is desired. Such a location of the outdoor unit adds extra dB of noise reflected from the wall. The dB level is not reported in the brochure and the location of the neighbors’ house is not shown in the image, but this sort of location should not be used alongside a place planned as a quiet place whether or not the unit is quiet. The Royal Palm Beach, FL 33411 Goodman heat pump outdoor unit is not a music performer performing to an audience.
