Air Conditioners Go Head-to-Head in Las Vegas

Learn how the 21-SEER 4-ton iQ Drive stood up in an efficiency test against 13-SEER 5-ton conventional air-conditioner. Interstate Plumbing and Air Conditioning out of Las Vegas, NV conducted the field test as a part of its Market and Technology Trials Program, which was designed to verify the energy savings achievable in a Nevada residential application.

For this trial, NV Energy compared both units at the same home. Homeowner Steve Schmid reported a 39% energy savings with the iQ Drive. To monitor energy usage and eliminate any variables that would alter the data being recorded, NV Energy installed: current sensors, current loggers, recording power meters and split-core transformers in Scmid’s home.

Results also showed that the iQ Drive unit provided a reduction of approximately 50% during the hours of 1pm and 7pm. NV Energy chose the iQ Drive air-conditioner for the study because of its published 21-SEER rating, the highest efficiency rating currently available for a 4-ton residential air-conditioner, according the NV Energy.

NV Energy’s Market and Technology Trials program performs an assessment and testing of innovative and energy-efficient technologies with applications in the residential, small commercial and industrial markets in Nevada.
