What Is the Average HVAC Installation Cost for a New System?

There isn’t a single average price for a new HVAC installation; the final cost is set after an in‑home assessment of system type, home size, and needed upgrades. The biggest driver is equipment selection and efficiency. Replacing furnace and AC together can reduce labor and ensures matched components. Our Denver‑area crew often designs around Lakewood homes’ existing ductwork and electrical capacity.

Your final price typically reflects:

• System configuration: AC + furnace, heat pump, or ductless
• Efficiency ratings that change equipment cost
• Duct modifications and airflow balancing needs
• Electrical upgrades, controls, and IAQ add‑ons
