ENERGY STAR Room Air Conditioners

Want to save money while keeping cool? Ask for ENERGY STAR. By earning the ENERGY STAR and meeting strict performance criteria, the room air conditioner will:

Save money. The average Maryland resident can cut cooling costs and save $135 over the lifetime of the unit.

Save energy. Qualified room air conditioners use at least 10 percent less energy than conventional models.

Improve comfort. Most ENERGY STAR qualified room air conditioners include timers for better temperature control and enhanced convenience.

Reduce noise. Qualified units run more quietly, to make your room more peaceful.

Save the environment. ENERGY STAR qualified products reduce air pollution and greenhouse gas emissions from power plants.

Did you know many people purchase room air conditioners that are too big for the room? Bigger units cost more up front, increase operating costs, and provide less comfort since short on/off cycles don’t properly dehumidify the room as it is cooled. Proper sizing is key to comfort and savings.
