How much does central air installation cost with existing ductwork?

Central air installation with existing ductwork is priced after an in‑home evaluation, because total cost depends on system size, efficiency, and the condition of your current ducts and electrical. Most price differences come from the equipment capacity and efficiency level you choose.

We handle the full process end‑to‑end and regularly complete these installs throughout the Whittier area. From the initial consultation to final testing, we handle every detail, including correct system sizing and system testing to ensure optimal performance. Financing is available (A/C Install As Low As $58/Mo + Same Day Install), and qualifying replacements may include seasonal savings (System Replacement Savings – Up to $1,992 OFF); final eligibility is confirmed during your visit.

Common cost drivers our technicians review on site:

  • Equipment size and efficiency rating
  • Any duct sealing, cleaning, or repairs needed
  • Thermostat upgrades or indoor air quality add‑ons (HEPA filtration, coil cleaning, etc.)
  • Site preparation needs for safe removal and placement

Schedule an in‑home evaluation to receive an upfront, written price before any work begins.
