How much does it cost to install a brand new AC unit?
The cost to install a brand-new AC depends on system type, home size, ductwork condition, and electrical needs. We offer free proposals with 4-hour arrival, and installations are available from as low as $120 per month with financing. A licensed, insured technician confirms final pricing after an in-home assessment. We install central AC and ductless mini-splits across Boise, Meridian, Nampa, Caldwell, and the Treasure Valley.
Quick steps:
- In-home assessment and load calculation.
- Options and financing review.
- Written proposal with final price.
- Scheduled installation.
