During routine HVAC maintenance, what should be checked?

• A. Filter condition, refrigerant levels, and system operation
• B. Only the air ducts
• C. The power supply only
• D. The thermostat batteries

Answer: (A)

During routine HVAC maintenance, it's essential to check filter condition, refrigerant levels, and system operation because these elements are critical for the overall efficiency and functionality of the HVAC system. The filter condition affects air quality and system airflow; a dirty filter can restrict airflow and cause the system to work harder, leading to higher energy costs and potential breakdowns. Refrigerant levels are vital for the cooling process in air conditioning systems. Low refrigerant can indicate leaks, which can severely impact system performance and efficiency. Ensuring that the refrigerant is at the correct level helps maintain comfort and efficiency. Finally, checking the overall system operation involves assessing various components such as the compressor, fans, and other mechanical parts to ensure they are functioning properly. This comprehensive approach to maintenance not only helps prevent unexpected failures but also extends the lifespan of the equipment, ensuring it operates efficiently throughout its service life. Other options like only checking the air ducts, just the power supply, or only the thermostat batteries do not provide a holistic view of the HVAC system's health. Focusing solely on one aspect could overlook crucial maintenance needs that impact system performance and reliability.
