Use the zone map below to identify your climate zone's designated number. Reading down the left-hand column of the savings chart below, select the cost/kwh rate in your zone that most closely approximates your local rate. Your approximate savings and payback period will be found at the intersection of your zone/rate line and the desired cooling capacity column.

Your exact savings will be determined by lifestyle, local electric rate and climate conditions. Savings are based on the relative operating costs of PTAC units; for specific savings details for your location, contact Carrier sales at 1-800-827-7435.
