the correlation between the air conditioner's capacity, expressed in tons and BTUs, and the required size of the capacitor. It shows that for smaller units, such as a 0.75-ton AC (9000 BTU), a capacitor between 25µF and 30µF is necessary. As the capacity increases, so does the required capacitance: a 1-ton unit (12000 BTU) needs 35µF to 40µF, and larger units, like the 2.5-ton AC (30000 BTU), require capacitors between 65µF and 70µF. Capacitors play an essential role in starting and maintaining the compressor motor, making their size crucial for the efficient operation of the air conditioning system.
