Central ac system installation cost — Centennial, CO

Last updated: September 24, 2026

What affects the price

When you are looking at the price of a new HVAC system, several variables come into play. The total depends heavily on the square footage of your home, the existing ductwork condition, and the efficiency rating of the unit you choose. Opting for advanced features like smart thermostats or high-performance air filtration will also shift the final number. If we need to modify your home’s electrical setup or gas lines to accommodate the new equipment, that adds to the labor requirements.
