Unit Design and Installation

AC units differ. Whether your need is residential, commercial, or industrial, units vary within today’s marketplace. Du-West installs high end top-tier equipment and materials. Inferior materials and practices can cause even the best cooling and heating units to perform below their designed capabilities.

Many HVAC contractors disregard manufacturer’s recommendations. Freon charging requires attention to detail. All equipment manufacturers require freon to be added or installed per the subcooling or superheat method. Du-West uses both methods. Rather than use the common practice known as “beer can charge” (the act of adding freon until the freon line is “cold as an iced down beer”, Du-West balances suction line temperature, pressure, and liquid line temperature and pressure as required by most equipment manufacturers.
