What can occur if the air filter in an HVAC system is clogged?

• A. Improved air circulation
• B. Increased energy efficiency
• C. Reduced system lifespan and overheating
• D. Better indoor air quality

Answer: (C)

When the air filter in an HVAC system becomes clogged, it restricts airflow, causing the system to work harder to maintain the desired temperature. This increased workload can lead to overheating, as the components of the HVAC system—like the compressor or motor—can become stressed under the strain of trying to push air through a restricted pathway. Over time, this constant strain can shorten the lifespan of the system, leading to potential breakdowns and costly repairs. Maintaining a clean air filter is essential for the efficient and long-term operation of HVAC systems to prevent these issues.
