What is a potential consequence of not replacing a dirty air filter regularly?

Not replacing a dirty air filter regularly can lead to increased energy costs and reduced system performance. A clogged or dirty air filter restricts airflow, causing the HVAC system to work harder to circulate air throughout the space. This extra workload on the system results in greater energy consumption, driving up utility bills.

Additionally, with limited airflow, the system may not effectively maintain the desired temperature, leading to inconsistent cooling or heating. Over time, this can cause wear and tear on vital components such as the blower motor and compressor, which may result in more frequent repairs and replacements, further implicating system performance and efficiency.

In contrast, an improved airflow, enhanced system longevity, and lower humidity levels would typically require a clean and well-maintained air filter, emphasizing the importance of regular filter replacements to avoid negative impacts on efficiency and costs.
