If you’ve lived in Agoura Hills for more than one summer, you know what’s coming. By late June, daytime temperatures in the Conejo Valley are pushing past 95 degrees regularly. When the Santa Ana winds roll through in September and October, we can hit 105 or higher. That kind of heat doesn’t just make you uncomfortable — it puts serious stress on your appliances.
Every summer, our call volume spikes. Refrigerators struggling to keep temperature. Dishwashers tripping breakers. Ice makers that can’t keep up. Most of these emergency calls could have been prevented with a little prep work in the spring.
Here’s what I recommend to every homeowner in Agoura Hills, Westlake Village, and Thousand Oaks before the heat arrives.
Your Refrigerator: The Hardest-Working Appliance in Summer
Your refrigerator runs 24 hours a day, 365 days a year. In summer, it works significantly harder because the ambient temperature around it rises — especially if your kitchen gets afternoon sun or your fridge is near a wall oven.
Clean the condenser coils. This is the single most impactful thing you can do. Dust, pet hair, and kitchen grease accumulate on the condenser coils over time, reducing their ability to dissipate heat. In a cool kitchen, dirty coils are an efficiency problem. In a 90-degree kitchen, dirty coils can cause the compressor to overheat and shut down.
On most standard refrigerators, the coils are behind the bottom kick plate. On Sub-Zero and other built-in units, they’re typically on top. Pull out the vacuum with a brush attachment, or better yet, use a dedicated coil brush. Do this twice a year — once in spring, once in fall.
Check your door gaskets. Close the door on a dollar bill. If you can pull it out without resistance, the gasket isn’t sealing properly. Warm air leaking into the cabinet forces the compressor to run longer cycles, which is the last thing you need when it’s 100 degrees outside. Gaskets can be cleaned with warm soapy water and a soft cloth — sometimes that’s all it takes to restore the seal.
Set your temperature correctly. The refrigerator compartment should be between 37 and 40 degrees Fahrenheit. The freezer should be at 0 degrees. I’ve walked into homes where the fridge was set to 34 degrees because the homeowner thought colder was better. All that does is overwork the compressor and freeze your lettuce.
Give it breathing room. Built-in units are designed with proper ventilation. But if you have a freestanding refrigerator, make sure there’s at least an inch of clearance on the sides and two inches behind. I’ve seen refrigerators pushed flush against the wall in Agoura Hills kitchens — that trapped heat has nowhere to go.
Your Dishwasher: Heat Plus Hard Water
The Conejo Valley has notoriously hard water. Mineral deposits build up inside your dishwasher year-round, but summer makes it worse because many households run the dishwasher more frequently — more entertaining, more cooking, more glasses of iced everything.
Run a cleaning cycle. Once a month, run an empty cycle with a dishwasher cleaner or a cup of white vinegar on the top rack. This dissolves mineral buildup on the spray arms, heating element, and interior walls.
Inspect the spray arms. Pull them out and check the small spray holes for mineral blockages. A toothpick works well for clearing them. Clogged spray arms mean poor cleaning performance, which means you run the cycle again, which means more wear on the pump and motor.
Clean the filter. Most modern dishwashers have a removable filter at the bottom of the tub. If you’ve never cleaned it, prepare yourself — it’s going to be unpleasant. But a clogged filter reduces water circulation and can cause the drain pump to fail prematurely. Pull it out, rinse it under hot water, and scrub it with a soft brush.
Check the door latch and gasket. A dishwasher that doesn’t seal properly won’t run a full cycle and can leak onto your kitchen floor. Run your finger along the gasket and feel for cracks, hardening, or gaps.
Your Washing Machine: Summer Means More Loads
Between pool towels, workout clothes, and the general reality of summer in Southern California, your washing machine runs more in summer than any other season.
Inspect the fill hoses. This is the one maintenance task that can save you from catastrophic water damage. The rubber hoses connecting your washing machine to the wall valves degrade over time. In summer heat, especially in a garage laundry setup where temperatures can hit 110 degrees, those hoses become more prone to bursting. If your hoses are more than five years old, replace them with braided stainless steel lines. It’s a $30 investment that can prevent $10,000 in water damage.
Leave the door open between cycles. This applies to front-load washers especially. Mold and mildew thrive in warm, damp environments — and summer in Agoura Hills provides exactly that. Leave the door ajar after each cycle to let the drum and gasket dry out.
Level the machine. A washing machine that rocks or vibrates excessively puts stress on the drum bearings and suspension springs. Place a level on top of the unit and adjust the leveling feet until it’s perfectly flat. This takes five minutes and can extend the machine’s life by years.
Your Oven and Range: A Quick Check
Ovens and ranges are less affected by summer heat, but they still deserve a look.
Test your oven temperature. Place an oven thermometer inside, set the oven to 350 degrees, and check after 20 minutes. If it’s off by more than 25 degrees, your thermostat or temperature sensor may need calibration or replacement. You don’t want to discover this on the Fourth of July when you’ve got 20 people coming over.
Clean the burner ports on gas ranges. Use a pin or needle to clear any food debris from the small holes on each burner head. Clogged ports cause uneven flames, which means uneven cooking and wasted gas.
The Big Picture: Prevention Over Emergency
I’ve been repairing appliances in Agoura Hills and the surrounding communities for 18 years. The pattern is always the same: homeowners who do a little maintenance in the spring rarely call me for emergencies in July. The ones who skip it are the ones calling on a Saturday afternoon when their refrigerator is at 55 degrees and they’ve got a house full of guests.
Thirty minutes of maintenance now can save you hundreds of dollars and a lot of stress later. Walk through your kitchen this weekend and hit the basics — coils, gaskets, filters, hoses. Your appliances will thank you when the thermometer breaks triple digits.
If you’d rather have a professional handle the spring tune-up — or if you’ve already got an appliance that’s struggling — give us a call at (818) 532-7208. We serve Agoura Hills, Westlake Village, Calabasas, Oak Park, Thousand Oaks, and the entire Conejo Valley. Let’s get your kitchen ready for summer before the heat arrives.
