The answer to 'when to service condenser' is that you should service your HVAC condenser unit at least once a year, typically in the spring before the hot summer months. Regular maintenance is important to ensure the condenser is running efficiently and to catch any potential issues before they become major problems.
During a condenser service, an HVAC technician will clean the coils, check refrigerant levels, inspect the electrical components, and perform other diagnostic tests. They may also recommend replacing the air filters and clearing any debris or vegetation around the unit. Proper maintenance can extend the life of your HVAC system and help it operate at peak performance.
