Installing central air with new ductwork is a custom-priced project that SALT confirms after an on-site evaluation. Home size and how much new ducting is needed usually drive the price most. Total cost also varies with equipment efficiency, any electrical work needed for the new system, and the complexity of routing ducts through your home. Our certified installers and in-house electricians focus on proper sizing, correct refrigerant charge, and tight duct connections, with testing before and after install to ensure performance. We bring decades of field experience to homes across the Austin area. Qualified buyers can use 0% financing for up to 18 months, and SALT+ members receive 5% off new HVAC installations with a lifetime guarantee on our work.
Consider these cost influencers during your estimate walk-through:
- Limited attic or crawlspace access that requires extra labor
- Electrical panel or circuit upgrades for the new equipment
- Added return vents, duct sealing, or line-set replacement
