A Qwik Performance Upgrade 
to New or Existing Systems.
What does this all mean…?
QwikSEER+™
 can save save homeowners 
as much as 7-13%* annually on their air 
conditioning operating costs. Finally, 
you can provide a low-cost alternative to 
expensive deluxe systems. Although deluxe 
systems can provide these savings and 
possibly more, they can cost thousands 
more than a standard system.
Here’s how it works…
QwikSEER+™
 is an innovative and cost-
effective electronic control that operates
in the cooling mode of an existing air
conditioner or heat pump. By using the 
existing speeds taps of a PSC motor, the 
QwikSEER+ control board selects the 
best possible airflow based on conditions 
in the home. This enhances system 
performance while providing energy 
savings and improved humidity removal. 
Fast Installation
Because of the QwikSEER+’s™ exclusive 
“plug & play” design, you won’t need to 
change any of the system controls or 
the current thermostats. QwikSEER+™ 
handles everything automatically and is 
compatible with your existing system.
The choice is simple...
Now you can offer your homeowners an 
affordable solution that will lower the 
energy costs of their existing systems 
(by about 10%) and increase the rate of 
humidity removal. 
*Independent Laboratory Testing at Intertek (Plano, Texas) following ANSI/ASHRAE 37 test 
protocol and using a residential 14 SEER air handler and condensing unit (80°F indoor, 
97°F outdoor temperatures) resulted in an EER improvement of 7.4%. Using the same 
condensing unit and temperature conditions with a residential furnace unit resulted in an 
EER improvement of 10.5%. On cooler days, (82°F outdoor temperature), the EER improve-
ments for air conditioning and furnace units increased to 10.9% and 12.9%, respectively. For
