If an AC unit has earned an ENERGY STAR® certification, it has a higher SEER rating and uses at least 8% less energy than conventional models. Get the cost of 1 ton, 2 ton, 4 ton and 5 ton ac unit. How can I tell whether the condenser (outdoor unit) is an air conditioner or heat pump? Please use this calculator to select which product you would like to calculate the total tonnage estimated for your project. The smallest unit is 18,000 BTUs (1.5 tons), while the largest is 60,000 BTUs (5 tons). There are many ways to make this calculation, depending on the level of precision required and the agency requiring the measurement. Over 40% of all HVAC systems, including central air conditioners, fail due to incompetent, hack job installation.
