Refrigeration Gas Solution, Inc. in Chula Vista specializes in EPA-compliant refrigerant recovery and recycling of commercial chillers and residential air-conditioning units from its Elder Avenue facility. Incorporated in California in 2022, the company removes and reclaims CFC, HCFC, and HFC refrigerants under EPA Section 608 protocols, a decommissioning step required before demolition projects managed by Fausto Construction Inc. during commercial build-outs. The operation handles scrap-out of rooftop package units, split systems, and walk-in cooler compressors for property managers, HVAC contractors, and restaurant operators throughout San Diego County. Post-recovery site preparation sometimes pairs with exterior cleaning crews such as SoCal Window Cleaning when building owners coordinate full-property maintenance before tenant turnover. Core equipment includes DOT-certified recovery cylinders, digital manifold gauges, and high-flow vacuum pumps rated to pull systems below 500 microns before final refrigerant extraction.
