These are all measurements used in the HVAC industry to help quantify cooling capacity. One ton of air conditioning can remove 12,000 BTUs (or British Thermal Units) of heat per hour. Larger homes will require an air conditioning system with more tonnage to properly cool the space.
SEER is the Seasonal Energy Efficiency Rating, and it has to do with efficiency. The higher the SEER rating, the more efficient your new air conditioner will be. This doesn’t mean that you necessarily need the AC unit with the highest SEER rating — there are lots of other variables to consider when choosing a new AC unit, and the SEER rating is just one of them.
