How do I Convert hvac seer to tonnage?

Determine the SEER rating of the HVAC system. The SEER rating is usually provided by the manufacturer and is a measure of the system's energy efficiency.

Find the total cooling capacity of the HVAC system in BTUs (British Thermal Units). This information is also typically provided by the manufacturer and can be found in the system's specifications.

Plug the SEER rating and the total cooling capacity in BTUs into the formula:

Tonnage = (Total Cooling Capacity in BTUs) / (SEER)

For example, if you have an HVAC system with a SEER rating of 16 and a total cooling capacity of 48,000 BTUs:

Tonnage = 48,000 BTUs / 16 SEER

Tonnage = 3 tons
