HVAC replacement cost may range from a minimum $3,000 to upwards of $12,500, which would include installation of both a new central A/C unit and gas furnace combo along with the cost of labor. If ductwork replacement is needed as well, you can expect an additional $2,500 for a typical single story 2,500 sq. ft home.

HVAC Unit Costs

Most homeowners who are looking at replacing an HVAC system will typically check what their old heating and cooling unit types were to make a decision as to which HVAC unit works best for their home. However, there are many combinations of heating units and cooling units that you can choose from depending on your needs. We have broken out below the average costs to install each different type of HVAC unit in order to give you an idea on pricing:

Which Factors Affect HVAC Replacement Costs?

• Current ductwork conditions
• Home age and construction
• HVAC unit features such as size, brand, and energy efficiency (SEER)
• Unit brand and associated installation costs

Home Age and Construction

The ability to cool and heat your home at maximum efficiency will depend on how well insulated your home is and the size of your home. A 4,000 square foot home will need a much larger AC unit than a smaller home, which will affect installation costs. Also a house with energy efficient windows that are well insulated and sealed well will require far less AC capacity to keep temperatures comfortable. Other factors that can affect this could be the insulation elsewhere such as the walls, attics, flooring, and more.
