HVAC maintenance is an important part of keeping your home or business comfortable and energy efficient. It involves regularly inspecting, cleaning, and servicing the heating, ventilation, and air conditioning (HVAC) system. This helps to ensure that the system is running at its peak performance and is not using more energy than necessary. It also helps to reduce the risk of breakdowns and costly repairs. HVAC maintenance should be done at least once a year, or more often if the system is used heavily. During maintenance, the HVAC technician will check the system for any problems, clean the filters, and make any necessary repairs. They may also adjust the settings to ensure the system is running as efficiently as possible. HVAC maintenance is an important part of keeping your home or business comfortable and energy efficient.
