Replacing an HVAC system is a major investment for homeowners, and the cost can vary widely depending on the size of the unit, the type of system, and the location. The national average for a basic HVAC system installation is around $5,500. However, the cost can range from $3,500 to $7,500 depending on the size of the unit and the complexity of the installation.

The type of system you choose will also affect the cost of installation. Central air conditioning systems generally cost more than window units, and heat pumps cost more than standard air conditioners. In addition, if you need to install ductwork, that can increase the cost of the installation. Depending on the layout of your home and the complexity of the installation, you could end up paying up to $20,000 for a complete installation.

The age of your existing HVAC system will also have an effect on the installation cost. Older systems may require additional work, such as the removal and disposal of the old unit, which can add to the installation cost. In addition, if you need to upgrade your electrical wiring to accommodate the new system, that can add to the cost of the installation.

The location of your home can also influence the cost of the installation. If you live in an area with higher labor costs, such as in a major metropolitan area, you can expect to pay more for the installation. In addition, if you live in an area with high energy costs, such as in California, the cost of the installation could be higher due to the need for more efficient systems.
