What Does SEER Mean?

What does SEER Mean?

HSPF,SEER, and AFUE are all cooling and heating ratings which are used to gauge the capability and efficiency of various systems. The standards are all governed and regulated by government departments, and every heating and cooling device in the market is assigned one of these ratings. People looking to buy such equipment thus need to know what these ratings mean.

Seasonal Energy Efficiency Ratio (SEER).

SEER is the total cooling output provided by a system during its operation divided by the total energy input. This is a rating which measures the efficacy of the chilling process of heat pumps and HVAC systems. A higher number translates to greater efficiency and more energy savings.

The minimum SEER number required by the government is 13.0. However, older systems have a rating of as low as 8.0. It would make sense to switch to equipment with a higher rating. For every $100 worth of energy consumed by a device with a rating of 8.0, the same level of cooling can be obtained from a 14.0-rated system, with about $42 realized in savings.

Average Fuel Utilization Efficiency.

AFUE rates the efficiency for oil and gas-powered furnaces and is usually indicated in percentages. The number shows the fuel consumed in heating a home and the level of wastage. A higher AFUE rating translates to more efficiency.
Heating Seasonal Performance Factor.

The HSPF rating indicates warming effectiveness of heat pumps (the SEER is what indicates the device’s cooling efficacy). A higher number translates to more efficiency and cost-savings. HSPF is a seasonal measure which considers the fact that heat pumps aren’t usually used much during the autumn and spring. The rating can thus be considered as the average factor for the whole heating period.
To calculate the HSPF the total yearly heating requirements are summed up and divided by the electrical power consumed. The industry standard system compares the BTUs of heating output to the total electrical wattage consumed (a watt of electricity has 3.4 BTUs). Most modern systems come with a HSPF of 6.8, with newer pumps required to have a factor of at least 7.

You can save money by upgrading to a heating/cooling system with a higher HSPF, AFUE and SEER ratings. To provide maximum energy savings for your home, you can contact an expert to recommend the perfect systems for your home. Call us for all of your home HVAC needs.
