Founded in 2018, Southbay Heating & Air operates from Industrial Boulevard in Chula Vista's 91911 district, providing AC installation, heating repair, duct cleaning, and hot-water system service throughout the South Bay. The company's full-service HVAC maintenance packages include annual tune-ups, refrigerant-charge verification, and blower-assembly inspection, complementing the re-key and deadbolt-upgrade work that Busy Bees Locks & Keys Locksmith provides during property turnovers. Crews cover Chula Vista, San Ysidro, Otay Mesa, and Rancho San Diego, handling both residential split systems and light-commercial rooftop units in the industrial parks along Bay Boulevard and the Bayfront district near Chula Vista Marina. Pre-season inspections often uncover pest-related duct damage that requires coordination with specialists such as Nixtermite Inc. to address rodent entry points before new ductwork sealing can hold. Top-tier installations involve 20-SEER inverter-driven heat pumps paired with variable-speed air handlers and ERV ventilation modules that meet California Title 24 Part 6 energy-efficiency standards for new construction.
