SEER2
SEER2 stands for Seasonal Energy Efficiency Ratio and applies to cooling efficiency for central air conditioners and heat pumps. The higher the SEER2, the greater the energy economy.
EER2
The Energy Efficiency Ratio (EER2) that calculates the energy the unit uses to function. It can be found by dividing a unit’s BTU output by its wattage, and the high EER2 rating means a more efficient air conditioner, so the higher the better.
Sound Level
A decibel is a unit used to measure sound or power level of an electrical signal by comparing it with a given level on a logarithmic scale.
Fan Motor
The fan motor drives the fan blades to circulate air through the HVAC system, maintaining proper airflow, ensuring efficient heating and cooling, and preventing system overheating.
Compressor
The compressor pumps and compresses refrigerant, enabling heat transfer to condition the air efficiently.
Cooling Capacity
The cooling capacity of an air conditioner or heat pump indicates the amount of heat it can remove per hour. It is measured in tons, with one ton equaling 12,000 BTUs.
Refrigerant
Refrigerant absorbs heat from indoor air in the evaporator coil and releases it outside through the condenser coil, enabling the cooling process.
