According to the US Department of Energy, the typical family spends nearly $2,000 per year on home energy bills. Much of that money, however, is wasted through leaky windows or ducts, old appliances or inefficient heating and cooling systems. That’s why all new Samsung® and Bosch® HVAC solutions are made with energy efficiency in mind.

If you’re in the market for a new HVAC system, knowing a few key terms will help you find the right one for your home.

SEER: Stands for Seasonal Energy Efficiency Ratio. The higher the SEER, the greater the energy efficiency. Higher SEER ratings will lead to lower electrical costs. In general, ductless systems typically use up to 40% less energy that conventional systems and window units.

AFUE: Gas furnaces use something called Annual Fuel Utilization Efficiency as their measurement of heating efficiency. The higher the AFUE, the greater the efficiency and energy savings potential.

BTU: The British Thermal Unit is the international measurement of energy—it’s the amount of heat needed to raise one pound of water by one degree Fahrenheit. For HVAC units, it measures the quantity of heat a conditioning unit can remove from a room in one hour.
