Regular AC service and cleaning isn’t just about comfort—it protects your system, lowers energy bills, and improves indoor air quality. For most homes in Fontana, a professional HVAC checkup is recommended at least once a year (often in spring before peak heat). If you run your system heavily, have pets, allergies, or live near dust and construction, twice-a-year maintenance can be a smarter choice. How do you know it’s time? Start with airflow. If some rooms feel warmer, vents blow weakly, or the system runs longer to reach the thermostat setting, your filter, blower, or evaporator coil may be dirty. Higher utility bills with no change in usage is another common clue—restricted airflow forces the AC to work harder. Pay attention to smells and sounds. A musty odor can indicate moisture buildup and microbial growth in the drain pan or coil area. Rattling, buzzing, or squealing may point to loose parts, worn bearings, or debris in the outdoor unit. Also watch for excess humidity indoors, frequent cycling on and off, or ice on the refrigerant line—these issues can be tied to dirty coils, low airflow, or refrigerant problems. Basic homeowner steps include replacing the air filter every 1–3 months, keeping vents unblocked, and clearing leaves and dust from around the outdoor condenser. However, deep cleaning (coils, drain line, blower components) and performance testing should be handled by a licensed technician. A proper service visit typically includes checking refrigerant readings, electrical connections, capacitor health, thermostat calibration, condensate drainage, and overall system safety. If your AC hasn’t been serviced in a year—or you notice any of the signs above—it’s likely time to schedule a cleaning and tune-up to restore efficiency and prevent expensive breakdowns.
