The Amana ASXC18 is a two-stage, high efficiency central air conditioner, which provides a SEER of up to 19 if it is properly installed with a matching air handler.
While it may not be obvious at first glance, the ASXC18 name conveys quite a bit of information about this series:
- “A” stands for Amana
- “S” stands for “split-system”
- “X” indicates that this is an air conditioner which uses R-410A (also known as Puron) as its refrigerant
- “C” indicates ComfortNet communications ready
- “18” indicates that it has a nominal efficiency (SEER) of 18
ComfortNet is designed to make the initial configuration and communication between the different elements of a residential HVAC system simpler. Once connected, ComfortNet will automatically configure any compatible air conditioners, heat pumps, furnaces, air handlers and blowers to optimize efficiency. Furthermore, the system monitors and stores diagnostic information, and can alert the homeowner that they should contact their contractor when a problem occurs.
While there are ComfortNet-compatible thermostats, ComfortNet does not connect to the internet. Diagnostic data can be retrieved by a contractor via a USB port.
Noisy vs Quiet
The ASXC18 is on the quiet end — the number of decibels of noise it produces varies primarily on the capacity (output) of the unit. A 3-ton model generates 71 decibels, the 4-ton 72 decibels, and the 5-ton produces 74 decibels.
