Serving Santee and San Diego County since 1973, ED Jones HVAC holds CSLB C-20 license #345817 and operates from Rockvill Street in the Woodside Avenue industrial corridor. The firm's all-in-house modelâno subcontractors on any jobâmeans the same crew that sizes the load calculation also installs the equipment and commissions the system, a continuity of workmanship that parallels the direct-hire approach used by Water Heaters Only, Inc. on Ablette Road for tankless and tank-style water heater replacements. Custom duct fabrication and full-system installations cover both residential retrofits in Santee's older housing stock and commercial tenant improvements. A Title 24 energy-code track record dating to 1973 positions the company to specify compliant equipment for California's evolving efficiency mandates, including the 2025 heat-pump-ready requirements affecting new construction coordinated by general contractors such as AMW General Contracting, Inc. on Cuyamaca Street. The highest-demand service involves legacy R-22 system conversions to R-410A or R-32 refrigerant platforms with matched evaporator and condenser coil replacements.
