The cost of replacing your HVAC unit is going to depend on what all needs to be replaced. Ideally, you’d only need to replace individual parts of the entire unit — pipes, valves, motors, compressors, etc., which The Home Depot prices anywhere from $100 for smaller issues to $1,000 or more for larger parts.
Even if you do need to replace the entire unit, the price will vary depending on if you also need to replace your ductwork. Switching out the unit itself costs an average of $7,000, according to Fixr, ranging in total from $2,000 to $9,000. Labor costs roughly $85 to $150 per hour, reports PickHVAC. If your air ducts are new and intact, this should be relatively painless, except for the cost of replacement. If your ductwork is old or damaged to the point it needs to be replaced, though, that’ll add on a substantial amount more. Fixr estimates ductwork replacement to cost $3,000 to $6,000, including the cost of labor and materials.
