When rainy weather arrives in Pasadena, it often brings more than grey skies and slick roads. Sudden storms and humidity spikes can leave homes feeling muggy, musty, or uncomfortable, and your HVAC system may struggle to keep up. Preparing now can protect your equipment and help your home stay comfortable throughout the season.
Protect Your Outdoor Unit From Storm Runoff
Heavy rain can cause water to pool around your outdoor AC or heat pump. Make sure the unit sits on a raised, level pad and keep the surrounding area free of debris. Clear gutters and downspouts so water is directed away from the equipment. Avoid using covers, as trapped moisture can damage components.
Manage Indoor Humidity
Rain increases indoor moisture levels, even in Southern California’s normally dry climate. High humidity can lead to discomfort, mold, and allergens. Run your HVAC system in “auto” mode for better moisture control and consider a whole-home dehumidifier if your home feels damp after storms.
Replace Air Filters More Frequently
Dust and pollutants build up during dry months, and moisture makes them circulate more easily. Rainy weather can clog filters faster than usual, so check them monthly and replace as needed to maintain airflow and air quality. We recommend replacing your HVAC filters every 30 to 90 days.
Inspect Ductwork for Moisture Issues
With ductwork often located in Pasadena attics, sudden humidity can lead to condensation or insulation damage. Professional duct inspection, sealing, and insulation help prevent mold and keep your system running efficiently.
Schedule Pre-Rainy-Season Maintenance
A preventive tune-up ensures your system is ready for wet weather. A technician will check your condensate drain, electrical components, refrigerant levels, and signs of moisture or corrosion and make needed repairs to help extend the lifespan of your system.
