A 3-ton air conditioning system is a central cooling unit with 36,000 BTU of cooling capacity. It is one of the most widely used sizes for residential homes and small commercial spaces in Florida.
A typical 3-ton system includes a matched outdoor condenser, indoor air handler, and evaporator coil designed to work together for efficient, reliable cooling.
This is one of the most practical and commonly replaced sizes for Florida homes, covering a wide range of residential and small commercial applications.
The indoor air handler draws warm air from your home through the return duct.
The refrigerant absorbs the heat from that air and carries it through the line set to the outdoor condenser unit.
The outdoor condenser releases the heat outside, and the now-cooled refrigerant returns inside to repeat the cycle.
