When properly matched and installed, your communicating Air Conditioner offers up to 24.5 SEER high-efficiency performance. The higher the SEER, the greater the efficiency — and the lower the operating cost compared to lower SEER units. In residential applications, you can increase your efficiency and decrease your cost just by installing these conventional air conditioners. Working in conjunction with a furnace with a variable-speed blower motor, you are not compromising comfort with limited temperature swings.
