My Spring Valley 1972 tract home needs HVAC replacement, what does it cost?
For a typical 1,400 to 2,200 sq ft 1960s-70s Spring Valley tract home, full heat pump conversion with duct sealing and smart thermostat integration runs $11,000 to $19,000 depending on equipment tier. Full ductwork replacement (when existing runs are not salvageable) adds $4,000 to $8,000. SDG&E rebates ($1,000 to $3,000) and federal 25C tax credit (up to $2,000) typically reduce net cost by $3,000 to $5,000 on qualifying installs. Manual J load calculation is included to size the new equipment correctly.
