How Much Does It Cost To Install Central Air Conditioning?

Central air installation cost with Diamond Heating and Cooling is set after an in‑home assessment because each home needs a custom design and code‑compliant install. You can use current savings like $600 off a new AC or $1,200 off a high‑efficiency complete system, and we provide free equipment estimates.

We perform load calculations and check your system layout before quoting, and installations are backed by money‑back, comfort, and no‑lemon guarantees. We install systems across the Boise area, including the Horseshoe Bend corridor.

Key factors that set your final price:

• System capacity and efficiency rating selected
• Ductwork condition, sizing, or modifications
• Electrical changes or line‑set updates needed
• Required permits and third‑party inspections

Schedule a free in‑home estimate so we can size the system correctly and provide a firm written price.
