The answer to 'heat pump installation cost' is that the cost can vary widely depending on several factors. In general, a typical heat pump installation can range from around $4,000 to $12,000 or more. The exact cost will depend on the size and efficiency of the unit, the complexity of the installation, the local labor rates, and any necessary ductwork or electrical work.
Larger homes or those requiring more extensive modifications will be on the higher end of that range, while smaller, simpler installations may be on the lower end. It's essential to get quotes from multiple local HVAC contractors to compare pricing and find the best option for your home and budget.
