HVAC Repair San Rafael CA | Call Chapman Heating and Cooing

A grinding noise often indicates a failing blower motor or bearings in the air handler, a common issue in our area. Continuing to run it can cause further damage. We recommend turning the system off and calling us for a prompt repair. Our technicians will diagnose the exact cause—whether it's a worn motor, debris, or misalignment—and fix it efficiently to restore quiet, reliable operation and prevent a complete system failure.

San Rafael's humidity can cause algae and mold growth in your AC's condensate drain line, leading to clogs and potential water damage. Our preventative maintenance service includes thoroughly cleaning the drain line, treating it with an algae inhibitor, and checking the condensate pump (if present). This simple, regular step is crucial for preventing overflows, protecting your home's foundation and walls, and ensuring your system runs efficiently all summer.

If your system is over 10-15 years old, requires frequent repairs (like repeated fan motor or drain line issues), and your energy bills are climbing, a replacement is often more cost-effective. Newer, high-efficiency systems are specifically designed for better performance in our local climate. We provide honest assessments, helping you weigh repair costs against the long-term savings and improved comfort of a modern, properly sized installation for your home.
