Ductless Air Conditioning Installation – Seasonal Energy Efficiency Ratio.

Seasonal Energy Efficiency Ratio (SEER) is a system for evaluating the efficiency of cooling equipment. Is calculated by dividing the cooling capacity of an air conditioner continuously operated by the electrical power input. The higher the SEER, the less the unit will cost to operate. The minimum SEER mandate today is 10, although most consumers tend to buy systems have achieved efficiency rates of 13 or more.

Seasonal Performance Factor Heating (HSPF). This measurement is similar to SEER, but it measures the efficiency of the heating portion of the heat pump. Like the SEER minimum industry HSPFs have increased in recent years. The current industry minimum is 6.80.

Ratings sound – in recent years, air conditioning has become not only more energy efficient, has become calmer. Although the sound does not affect the efficiency of a unit, it can certainly affect your comfort. If your unit has a low noise level, you (and your neighbors) hardly will notice when operating.

Sound Level Number (SRN). One way to measure how strong a unit operates, based on evidence of acute respiratory infections. Sound Average ratings ranging from 74 to 80 decibels, or dB. The lower the SRN rating, the quieter the unit. In recent years, air conditioning has become not only more energy efficient, has become calmer. Although the sound does not affect the efficiency of a unit, it can certainly affect your comfort. If your unit has a low noise level, you (and your neighbors) hardly will notice when operating. Typically, heat pumps and air conditioners are among the sound of a human voice (70 dB) and a blender (88 db)..
