A professional would typically charge anywhere from $2,000 to $4,000, depending on your location, the complexity of the job, and the contractor’s rates. This price would usually include labor, materials like the line set, electrical wiring, and any necessary permits. Since your setup sounds pretty simple (no major obstacles or complicated runs), it should fall on the lower end of that range, but it’s always a good idea to get a few quotes to compare. Be sure to ask if he quote covers everything, including testing and ensuring the system works properly, so there are no surprises later!
