However, most homeowners pay around $8,000. The size of your home, the type of unit, and the complexity of the installation ultimately determine how much it will cost to upgrade your home's climate control.

    Cost Factors in HVAC Replacement

    HVAC contractors charge clients based on the time, expertise, and materials needed to complete an installation. The unit itself accounts for a significant chunk of an HVAC budget. In addition to charging for the unit, an HVAC pro also charges for specialized labor, permits, and modifications to existing ductwork or electrical systems.
