What are SEER & EER?
Air Conditioners and Heat Pumps are rated in SEER (Seasonal Energy Efficiency Rating) and EER (Energy Efficiency Rating.) EER measures the energy efficiency of an air conditioner at one operating temperature, while SEER is the calculation using varying temperatures. The higher the SEER rating the more efficient the equipment.
Motors
An ECM motor is a high efficiency motor which reduces energy cost.
A fully variable speed ECM motor is the most efficient motor available and ramps up and down slowly, providing a wide range of operation possibilities. The quiet start and stop also is done gradually as the motor ramps up and down, providing high levels of dehumidification and low cost operation should you decide to circulate your air 24/7. In addition to the savings with two stage compressors and inverter compressors, many high efficiency Air Conditioners and Heat Pumps have higher efficiency outdoor condenser fan motors which also save money on electric.
What is AFUE?
AFUE stands for Annual Fuel Utilization Efficiency. Furnaces range in efficiencies from 80-98% AFUE. The higher the efficiency, the less gas you use and the more you save.
Gas Valves
- A Single-stage gas valve furnace simply turns on and shuts off with a call for heat.
- Two–stage gas valve units lower energy cost by operating in first stage (2/3 of normal output,) and switching to second stage (100%) as needed.
- A Modulating gas valve furnace operates at a wide range of outputs (usually 30%-100%) depending on weather conditions.
