EER Rating vs. Equipment payback
The published EER rating represents efficiency of cooling products at peak load, or 95ºF
(35ºC). This rating is driven by utility companies that are concerned with power
consumption at peak demand periods. In most locations, peak load is experience for a very
short time during a year (see charts below). The even-size ICP inverter units are designed
for high efficiency at lower load conditions, which represents the vast majority of the cooling
season. This is why the SEER ratings are high, but the EER is not as high as other high-
efficiency products. 2015 Regional Standards for the Southwest require higher EER ratings
as well as some local incentives and rebates, however many regions do not require a higher
EER rating. The even-model sizes focus on high SEER ratings which allows for smaller unit
design and competitive price. For the Southwest region and other markets requiring higher
EER ratings, the odd-size units will be available for these applications.
A cost analysis should be done to compare benefit of a rebate with higher EER models vs.
the cost of the lower EER models. Things to consider regarding rebates containing EER
requirements:
(Cost of qualifying EER equipment) – (rebate amount) = ______________
Cost of ICP Inverter equipment = _____________
In many cases, the cost of the even-size ICP inverter product may be less than a
competitive product less the rebate.
