Selecting the most energy-efficient a / c and home heating system is a lot more important than ever before, as San Francisco Bay Area utility prices consistently rise. However, deciding which heating or cooling system is the most efficient isn't necessarily as simple as it appears. HVAC energy measurements can often be perplexing.
HVAC energy measurements
The heating, ventilation and cooling industry (HVAC) utilizes an variety of measuring scales to show the energy efficiency of household cooling and heating systems. The Energy Star rating system, established by the US Department of Energy (DOE) in 1992, gives shoppers ways to tell right away if an appliance meets the DOE’s minimum efficiency standards. Search for a large, yellow sticker along the side of the unit. This system also allows you to easily do a comparison of two products manufactured by different companies.
The annual fuel utilization efficiency (AFUE) presents consumers a solid idea of how good a heater performs. This number is indicated in a percentage. For example, an AFUE of 90 shows that the home heating system is 90 % efficient.
The seasonal energy efficiency ratio (SEER) measures the cooling effectiveness of heat pumps and a / c system. The greater the ratio, the more efficient the device. To become qualified as an Energy Star-rated appliance, a unit will need to have a rating of a minimum of 12, but you'll find systems available with ratios as high as 20.
The heating seasonal performance factor (HSPF) measures the efficiency of heat pumps. The amount is the total heat generated by the pump (in Btus) throughout a single heating season.
