Common signs include your AC system running constantly but not cooling effectively, ice forming on the refrigerant lines or evaporator coil, and a noticeable hissing or bubbling sound near the indoor unit. If you notice these, it's best to call for a professional diagnosis to prevent further damage to the compressor.

For most Simpsonville homes, we recommend checking your standard 1-inch filter every month and changing it every 1-3 months, especially during peak summer and winter usage. Homes with pets, allergies, or more dust may need monthly changes. A clean filter protects your system and maintains good indoor air quality.

Yes, over time, a severely clogged filter restricts airflow, causing the system's blower motor to overwork and the heat exchanger or evaporator coil to overheat. This strain can lead to premature component failure, like a seized motor or a cracked heat exchanger, resulting in a costly repair or full system shutdown.
