SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) are measures of efficiency for heat pumps. SEER and HSPF ratings are like miles per gallon in cars - the higher the rating, the more energy efficient the unit and the more money you save. All American Standard systems satisfy or exceed minimum government SEER and HSPF standards. Choose a higher efficiency unit for greater savings.
Q: What is the difference between SEER Ratings and tons?
A: SEER is a measurement of the efficiency, while tons is a measurement of size. One ton of air conditioning is equivalent to 12,000 BTU. A BTU is a British Thermal Unit, and it is simply a measurement of heat.
One BTU is roughly equivalent to the amount of heat generated by burning one wooden kitchen match.
Simply put, this means that a one-ton air conditioner can remove 12,00 BTU from a space per hour.
To determine what size air conditioner your home needs you can call MARTIN'S to match the size of the unit to the BTU requirements for your house. A general rule of thumb for an average home is about 500 square feet per ton. Be sure to look for a properly sized system, bigger is definitely not better. A larger-than-necessary system will turn on and off more frequently and cost more to operate than a properly sized system. Sometimes SEER ratings and tons can get very confusing, but don't worry the friendly people at MARTIN'S are ready and willing to help you with all your questions. Have a nice day.
