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.
HSPF2
Heat pumps heat your home using electricity as their fuel source, and their efficiency is measured as Heating Seasonal Performance Factor (HSPF2). The higher the HSPF2, the greater the efficiency and the greater your energy savings potential.
Zones
A single-zone ductless system heats or cools one specific area with a single indoor unit, while a multi-zone system connects multiple indoor units to one outdoor unit, allowing for individualized climate control in different rooms or zones.
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.
