High Energy Bills? What Does Your Air Conditioning Cost To Operate?

'A penny saved is a penny earned' as the old adage goes… clearly an attempt at saving money on energy costs during air conditioning season makes sense. We often hear the word SEER. As HVAC contractors serving homes and businesses in Northern New Jersey it's a familiar buzz-word in our environment. What does it mean and how does it affect you? Our friends at Energy Star provide a lot of information. Read on….
Seasonal Energy Efficiency Ratio (SEER), is most commonly used to define and measure the efficiency of a central air conditioning unit. The rule of thumb is: The higher the SEER rating, the more efficient the system. SEER measures how efficiently a cooling system will operate over an entire season.
  • In technical terms, SEER is a measurement of the total cooling of a central air conditioner or heat pump (in BTUs) during the normal cooling season as compared to the total electric energy input (in watt-hours) consumed during the same period Energy Efficiency Ratio

Energy Efficiency Rating (EER) is a measure of how efficiently a cooling system will operate when the outdoor temperature is at a specific level (95oF). The higher the EER, the more efficient the system.

  • In technical terms, EER is the steady-state rate of the removal of heat energy (i.e. cooling capacity) by the product measured in Btuh divided by the steady-state rate of energy input to the product measured in watts. This ratio is expressed in Btuh/watt.

Both SEER and EER are detailed in ENERGY STAR specifications because each rating indicates the energy efficiency of the product under different operating modes. SEER rating more accurately reflects overall system efficiency on a seasonal basis and EER reflects the system’s energy efficiency at peak day operations. Both ratings are important when choosing a product.

Here’s some more information about SEER . While it may appear to be hieroglyphics, we thought you might want to know! New Jersey Residents, Visit our Website for more information on replacing your Air Conditioning System with new High-Efficiency Air Conditioning Equipment. You'll save on energy costs, earn Federal Tax Credits before the end of 2010 (and possibly local utility company rebates) and enjoy comfort with new technologies in cooling.
