Why does HVAC cost more in Coronado than in San Diego proper?
Salt air is the main driver. A standard condenser placed in Coronado loses 30 to 50 percent of its service life to corrosion, so we spec coastal-rated equipment with corrosion-protected coils and stainless hardware, which typically adds $800 to $1,800 over standard equipment. Historic Preservation review on Village contributing structures can also add screening or concealed line-set work, generally $1,500 to $3,500, though it doesn't apply to every property.
