When Things Go Wrong, Call the Pros](#sec-when-things-go-wrong-call-the-pros) When the mercury climbs in San Jose, your appliances work harder than ever. The combination of dry heat, occasional humidity spikes, and long summer days can push refrigerators, air conditioners, and washing machines to their limits. A little proactive care now can save you from a hot, sticky repair call in August. Here is a practical guide to help your home's essential machines survive and thrive through the season. ## Give Your Refrigerator Some Breathing Room Your refrigerator is the hardest-working appliance in a San Jose summer. With outside temperatures often topping 90 degrees, the compressor runs longer to keep your food cold. The biggest mistake homeowners make is blocking the condenser coils. These coils, usually located on the back or bottom of the fridge, release heat. If they are caked with dust or pushed against a wall, the fridge struggles to cool. Start by pulling the refrigerator away from the wall and vacuuming the coils with a brush attachment. Do this at least once a year, but twice is better for summer. Also check the door seals. A warm day can make rubber gaskets brittle or loose. Close a dollar bill in the door; if it slides out easily, the seal is weak. Replace worn gaskets promptly. Finally, keep the fridge at least an inch away from the wall to allow airflow. This simple step can reduce energy use and prevent a compressor burnout on the hottest days. ## Prepare Your Air Conditioner for Peak Performance A struggling air conditioner in San Jose is more than an inconvenience—it can be a health risk. Whether you have a window unit or a central system, start with the filter. A dirty filter is the number one cause of poor cooling and frozen coils. Check it monthly during summer and wash or replace it as needed. For central systems, also clear any debris from the outdoor condenser unit. Leaves, grass clippings, and dirt can block airflow and force the system to overheat. If you have a window unit, inspect the seals around the frame. Gaps let hot air in and cool air out. Use foam weatherstripping to close any leaks. For central systems, consider a professional tune-up before the season peaks. A technician can check refrigerant levels, clean the evaporator coil, and ensure the fan motor is running smoothly. A well-maintained AC uses less electricity and keeps your home comfortable without sudden breakdowns. ## Protect Your Washing Machine and Dishwasher from Heat Stress Heat can affect water-using appliances in surprising ways. Your washing machine, for example, may develop rubber seal cracks if left in a hot garage or laundry room. Check the door gasket for any signs of drying or cracking. Wipe it down after each use to prevent mildew, which thrives in warm, damp conditions. Also, run a cleaning cycle with a washing machine cleaner or white vinegar once a month. This removes mineral buildup from San Jose's hard water, which can clog valves and reduce efficiency. For your dishwasher, focus on the filter and spray arms. Summer means more guests, more dishes, and more strain on the machine. Remove the bottom filter and rinse away food particles. Check the spray arms for clogs by running water through them. If water doesn't spray evenly, use a toothpick to clear the holes. A clean dishwasher runs faster and uses less hot water, which also helps your water heater handle summer demands. ## Keep Your Water Heater and Garbage Disposal in Check San Jose summers often mean more showers, more laundry, and more dishwashing. Your water heater works overtime. To avoid running out of hot water, set the thermostat to 120 degrees Fahrenheit. This is safe for most homes and reduces energy waste. If you have an older tank, drain a few gallons of water from the bottom once a year. This removes sediment that can insulate the water from the heating element, forcing the unit to run longer. Your garbage disposal also needs attention. Warm weather can cause food scraps to decompose faster, leading to odors. Run cold water while using the disposal, and grind ice cubes and lemon peels once a week to clean the blades and freshen the drain. Avoid putting fibrous foods like celery or potato peels down the disposal, as they can jam the motor. A little care now prevents a smelly backup during a summer barbecue. ## When Things Go Wrong, Call the Pros Even with the best preparation, appliances can fail. The heat wave that pushes your refrigerator to its limit might also cause a capacitor to fail in your air conditioner. If you notice unusual noises, warm air from vents, or a fridge that won't stay cold, do not wait. Delaying repairs can turn a simple fix into a major replacement.
