In Sacramento homes with attic ductwork, heat-damaged ducts are very common."},{"question":"How much does duct sealing cost in Sacramento?","answer":"Professional duct sealing in the Sacramento area costs $300–$1,000 depending on the size of your system and accessibility. Aeroseal (a pressurized sealant sprayed inside ducts) costs $1,500–$2,500 but is more thorough. Duct sealing typically pays for itself in 1–2 years through energy savings."},{"question":"How much does ductwork replacement cost?","answer":"Full ductwork replacement in a Sacramento home costs $2,000–$5,000 for a typical single-story home and $4,000–$8,000 for two-story homes. The cost depends on home size, duct material chosen, and accessibility. Older Sacramento homes with attic-mounted ductwork may need complete replacement due to heat degradation."},{"question":"How much energy do leaky ducts waste?","answer":"Leaky ducts can waste 20–30% of the conditioned air your HVAC system produces. In Sacramento's summers, when your AC runs 8–12 hours a day, that translates to $50–$150 per month in wasted energy. Sealing and insulating ductwork is one of the most cost-effective home efficiency upgrades."},{"question":"Do I need a permit for ductwork in Sacramento?","answer":"New ductwork installation and major modifications require a mechanical permit in Sacramento County. Minor duct repairs and sealing typically do not require permits. California's Title 24 energy code has specific requirements for duct insulation and sealing that must be met during any permitted work."}],"related_services":[{"slug":"ac-repair","name":"AC Repair","price_range":"$150–$650"},{"slug":"ac-replacement","name":"AC Replacement","price_range":"$4,500–$15,000"},{"slug":"heat-pump-installation","name":"Heat Pump Installation","price_range":"$6,000–$18,000"},{"slug":"furnace-repair","name":"Furnace Repair","price_range":"$125–$500"},{"slug":"furnace-replacement","name":"Furnace Replacement","price_range":"$3,500–$10,000"}]}}
