Yes, a failed capacitor is one of the most common causes of sudden AC failure, especially during our hot and humid summers. The capacitor helps start your outdoor unit's compressor and fan motor. When it fails, your system won't turn on. PMC Mechanical's technicians carry common capacitors on our trucks and can often diagnose and replace yours the same day to restore your cooling quickly.

We recommend checking your air filter every month and replacing it at least every 1-3 months. In our coastal area, factors like pollen in the spring, high humidity in summer, and general dust can clog filters faster. A dirty filter restricts airflow, making your system work harder, increasing energy bills, and potentially leading to costly repairs. It's one of the simplest ways to maintain your system's health.

Watch for weak airflow from vents, strange noises (like grinding or squealing), unusual odors, frequent cycling on and off, or rising energy bills without increased usage. These are often warnings of issues like dirty components, failing parts, or refrigerant problems. Addressing them early with a PMC Mechanical technician can prevent a minor issue from becoming a major, inconvenient breakdown.
