The answer to the cost of a system upgrade is that it can vary widely depending on several factors. Generally, upgrading an HVAC system can range from a few thousand dollars to $10,000 or more, depending on the size of your home, the complexity of the installation, and the specific equipment you choose.
Some key factors that influence the cost include the type of system (e.g., furnace, air conditioner, heat pump), the efficiency rating, the brand and model, the need for ductwork modifications, and the labor costs in your local area. Older homes may also require additional work to bring the electrical or gas systems up to code. Getting multiple quotes from reputable local HVAC contractors is essential to understanding the true cost for your specific situation.
