The answer to 'average cost for air handler' is that the typical range for an air handler replacement can vary widely depending on several factors. Generally, you can expect to pay anywhere from $2,000 to $8,000 or more for a new air handler unit and installation.
The specific cost will depend on the size and efficiency of the unit, the complexity of the installation, and your local labor rates. Larger homes or units with advanced features like variable-speed motors or smart controls will be on the higher end of that range. Additionally, the cost can vary significantly based on your geographic location and the specific contractor you hire.
