Category: Central Air Conditioning Repair (Page 1 of 6)

A central AC unit is a complex system that requires refrigerant to cool the air. The frequency at which a central AC unit needs charging with refrigerant depends on several factors, such as the size of the unit, its age, and any potential leaks in the system. It is recommended to have a professional HVAC technician inspect and recharge the unit every 1-2 years to ensure optimal performance and efficiency. 

Depending on the usage and maintenance of the unit, some central AC units may require more frequent charging with refrigerant. Regular maintenance, such as cleaning or replacing air filters and checking for leaks, can help prolong the time between charges. It is important to monitor the unit for any signs of decreased cooling efficiency or unusual noises, as these may indicate a need for refrigerant recharge.
