The answer to 'when to service inspection' is that HVAC systems should be inspected and serviced at least once a year, typically in the fall before the heating season begins. This annual maintenance helps ensure your system is running efficiently and safely, and can help prevent costly breakdowns or repairs down the line.
During a service inspection, an HVAC technician will thoroughly check your system, including the thermostat, air filters, refrigerant levels, electrical connections, and other critical components. They may also clean the system, lubricate moving parts, and make any necessary adjustments or minor repairs. This proactive maintenance is essential for extending the lifespan of your HVAC equipment and keeping your home comfortable year-round.
