The answer to 'how to maintain installation' is to regularly inspect, clean, and service your HVAC system. This includes changing air filters, cleaning coils, and ensuring all components are functioning properly. Proper maintenance can extend the lifespan of your HVAC system and improve its efficiency, saving you money on energy bills.
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 this service, the technician will thoroughly inspect the system, make any necessary adjustments or repairs, and provide recommendations for ongoing maintenance.
