According to the company, QwikSEER+ provides for a simple retrofit of existing air conditioning and heat pump systems using permanent split capacitor (PSC) motors. PSC systems are installed with the blower fan set to run at a single speed, even though the motor is capable of running multiple speeds. The QwikSEER+WattSaver control board monitors evaporator coil temperature and humidity levels and automatically selects the optimal fan speed based on real-time environmental conditions. The end result is savings of up to 13 percent in energy usage and lower humidity levels, supplying increased comfort at lower cost, says the company.

“As spring tune-up time is upon us, HVAC contractors are looking for low-cost options to help their customers save money on their electricity bills,” said Robert Scaringe, president of Mainstream Engineering. “Previously, the only option for homeowners who wanted more energy-efficient HVAC in their homes was to upgrade the system using far more expensive X13 or electronically commutated motors (ECM). QwikSEER+ provides a simple upgrade to an existing PSC motor at a cost that pays for itself in less than two years.”

With its plug-and-play design, the control board can be quickly installed, and no changes to the system controls or thermostat are necessary; QwikSEER+ handles everything automatically, says the company. Since humidity levels are reduced, homeowners often can increase their thermostat setting by one to two degrees, resulting in even greater energy savings.
