How frequently should the coils in an HVAC system be cleaned?

• A. Every few years
• B. At least once a year or as needed
• C. Only when visible dirt is present
• D. Once a month

Answer: (B)

The coils in an HVAC system should be cleaned at least once a year or as needed to ensure optimal performance and efficiency. Regular cleaning helps to remove dirt, dust, and other contaminants that can accumulate on the coils, which can hinder the heat exchange process. This buildup can lead to reduced system efficiency, higher energy costs, and potential system failures if left unaddressed. Seasonal maintenance is essential for maintaining airflow and ensuring that the HVAC system operates under its designed conditions, ultimately extending the lifespan of the system and enhancing indoor air quality. Additionally, specific environmental factors or usage patterns may necessitate more frequent cleaning, hence the phrase "or as needed" indicates flexibility based on individual circumstances.
