The answer to 'how to fix preventive maintenance' is to regularly perform routine maintenance tasks on your HVAC system. This includes cleaning or replacing air filters, inspecting and cleaning the condenser coil, lubricating moving parts, and checking electrical connections. Proper preventive maintenance helps extend the lifespan of your HVAC system, improves energy efficiency, and reduces the risk of unexpected breakdowns.
It's recommended to have your HVAC system serviced by a professional technician at least once a year, typically in the spring or fall before the peak heating or cooling season. During a tune-up, the technician will thoroughly inspect your system, make any necessary adjustments or repairs, and provide recommendations for ongoing maintenance.
