Mojave River bottom dust loads are heavier in Victorville than ridge cities, which affects AC install spec in two ways. First, outdoor condenser coils need more frequent cleaning, so we recommend semi-annual coil cleaning service agreements ($200-$350 per year). Second, air filter cabinets sized for 1-inch filters load up in 30-45 days vs 6-12 months for 4-inch media filters. We upsize filter cabinets to 4-inch media on every Victorville install. Permit pulled and final inspection coordinated through City of Victorville mechanical permit office. Most Victorville installs are like-for-like swaps where existing line-set, electrical, and ductwork are sized correctly, which keeps install time to one day. R-22-to-A2L conversions need new line-set (incompatible refrigerant), which extends install to 1.5-2 days.
