Product Overview

Merit® 16ACX Series 16ACX Air Conditioner

High-Efficiency, Two-Stage Cooling

Merit 16ACX's two-stage technology optimizes performance compared to conventional single-stage systems, resulting in more even temperatures and lower utility bills. High-quality components assure a high level of reliability, even under the harshest outdoor conditions.

Energy Efficiency

  • Efficiency ratings of up to 17 SEER—can save hundreds of dollars a year, compared to a standard air conditioner
  • ENERGY STAR® qualified—meets or exceeds EPA guidelines for energy efficiency
  • High-efficiency outdoor coil—provides exceptional heat transfer and low air resistance for high-efficiency operation

Quiet Operation

  • Sound levels as low as 74 dB—much quieter than a standard air conditioner
  • Precision-balanced direct-drive fan—delivers ultra-quiet operation with a patent-pending fan design

Home Comfort

  • Two-stage scroll compressor—operates at low stage most of the time for quieter, more efficient performance
  • Designed to work with the Humiditrol® whole-home dehumidification system**

Environmental Responsibility

  • Chlorine-free R-410A refrigerant—provides exceptional comfort without exacting a costly environmental toll

Reliable Performance

  • PermaGuard™ Cabinet—heavy-gauge, galvanized steel construction, louver coil guard, baked-on powder finish and durable zinc-coated steel base provide long-lasting protection against rust and corrosion
  • SmartHinge™ louver design—allows quick, easy access to interior components from all sides for cleaning and maintenance. Protects coils from damage and provides clean appearance
  • Drainage holes—prevent damaging moisture from collecting inside the basepan

*The region used to calculate household fuel and utility costs reflect a cross-section of cities in the U.S. In addition to geography, cooling costs are based on 3-ton capacity specifications, with 1,800 cooling hours per year and 11.62 cents per KWh (Source: EIA National average electric rate-Rolling 12 months ending July 2009). Actual costs will vary depending on the weather, local fuel rates, system settings and personal lifestyle.

**Must be accompanied by either a variable speed air handler or furnace and the ComfortSense™ 7000 Series touchscreen thermostat.
