San Antonio insulation upgrades pay back fast given CPS Energy TOU rates and TX's heat. Most pre-1990 SA homes have R-19 to R-30 attics — well below the modern R-49+ target. Spray-foam under the roof deck (conditioned attic) increasingly popular. NeedInstall connects you with SA insulation contractors who handle CPS Energy rebate paperwork, blower-door testing, and conditioned-attic conversions.
SA attic top-up to R-49+: $1,800-$4,500. Conditioned-attic spray-foam: $4-$7 per sq ft. Duct sealing/insulation: $1,500-$3,500. TX requires no state insulation license but contractor's license common. CPS Energy rebates ($300-$1,500). Blower-door test ($300-$500) often required.
