HVAC Services San Rafael CA | Call Gibbs Heating & Air Conditioning

In San Rafael, with our local dust and pollen, we generally recommend checking your standard 1-inch filter every month and replacing it every 1-3 months during peak heating and cooling seasons. A clogged filter is one of the most common causes of poor airflow, reduced efficiency, and even system breakdowns. During our routine maintenance visits, we'll check your filter and advise on the best schedule for your specific system and household.

Common signs your air handler fan is failing include weak airflow from your vents, unusual humming or grinding noises from the indoor unit, the system frequently tripping its circuit breaker, or your HVAC system running but not heating or cooling your San Rafael home effectively. If you notice any of these issues, it's best to call for a professional diagnosis. Our technicians can quickly identify if it's a simple capacitor replacement, a worn motor, or another issue to restore proper operation.

Absolutely. Our comprehensive HVAC maintenance service is specifically designed to prevent the most frequent issues we see in San Rafael homes. We thoroughly clean components, check refrigerant levels, inspect electrical connections, lubricate moving parts, and test the air handler fan and blower assembly. This proactive care catches small problems—like a dirty filter straining the fan—before they lead to a major repair or a complete system failure during a heatwave or cold snap, ensuring your comfort and peace of mind.
