Our calculator is pre-set to compare a 3 ton, 14 SEER air conditioner to a new 3 ton, 18 SEER unit, at the current Georgia Power per-kilowatt hour cost of retail electricity and our area’s average annual cooling operating hours (or how many hours you could expect your unit to run during the year) — but you can adjust the settings based on your home or commercial building’s unique characteristics by toggling to your current SEER rating, its tonnage, and the SEER rating of a new air conditioner or heat pump installed by Air Control.
Tonnage is a measure of the size and cooling capacity of your air conditioner — but air conditioning tonnage has nothing to do with weight. A ton, as used in the HVAC field, is a term that describes how much heat the air conditioning unit can remove from a home in one hour.
The measurement for heat is the British Thermal Unit (BTU). One ton of air conditioning can remove 12,000 BTUs of air per hour, so a four-ton unit can move 48,000 BTUs (and so on). What all this means is that the more tonnage an AC unit is rated at, the more air it can cool.
Finding the tonnage of your unit should be as simple as walking outside and reading the label on the outside (condenser) unit, which should have a data plaque mounted on the side. Most of the time, manufacturers list BTUs instead of tons, so divide the BTUs by 12,000 to calculate the tonnage of your unit.
Look for an even, two-digit number between 18 and 60 (or you might see a three-digit number starting with 0).
If you find one of those numbers, chances are it’s the unit’s BTUs:
SEER (Seasonal Energy Efficiency Ratio)
The SEER measures air conditioning and heat pump cooling efficiency, which is calculated by the cooling output for a typical cooling season divided by the total electric energy input during the same time frame. A higher SEER rating means greater energy efficiency.
The current minimum standard SEER rating in Georgia is 14.3 for air conditioners, and most modern units have a SEER that range from 14.3 to 21 (ENERGY STAR® qualified central air conditioners must have a SEER rating of 15.2 to qualify).
Your AC unit’s SEER should also appear on the outside unit, as a 2-digit SEER (it’s also found on the air handler attached to your furnace).
