How much does it cost to install central air with ductwork?

The cost to install central air with new ductwork is set after an in-home load calculation and duct design, because equipment capacity and the full duct scope determine the total. Most added cost comes from redesigning ducts so each room gets the right airflow and pressure balance.

We provide bullseye-accurate, no‑obligation estimates with the whole price shown, and we tune the new system for peak efficiency. Our team regularly installs systems across DFW homes, including projects in McKinney with tight attic runs.

Typical factors that set the price:

• Square footage and load results (tonnage/BTU sizing)
• Amount and type of new ductwork, plus sealing and insulation levels
• Efficiency rating and compressor type, plus thermostat or smart controls
• Needed electrical or condensate upgrades and any air-quality add‑ons
