QualitySmith.com explains that the price for a Payne air conditioning unit can vary widely, between $1,900 and $6,500 per unit, according to the contractor used and the model. This is because Payne units are not available by retail, but instead are sold directly to the contractors.
The larger the air conditioning unit, the higher the total installed price. A 13 SEER unit costs a contractor between $1,900 and $5,500, depending on region and the amount of work necessary for the installation. For a larger 16 SEER unit, the price rises to typically about $2,400 to $6,500. The prices include labor costs, which also vary greatly by region.
