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.
