Most San Diego homes have a mix of appliances in a mix of micro-climates. A fridge in the kitchen sees steady conditions. A garage refrigerator sees 100°F+ summer days. A laundry pair in a coastal zip code fights salt humidity. All of them benefit from seasonal checks — and most of those checks take 10 minutes and cost nothing.

Here’s the checklist we give customers who ask “what should I be doing?”

Spring — April through May

The goal: prep appliances for the warm-weather season when cooling and ventilation matter most.

Refrigerator

  • Clean the condenser coils (bottom rear on most modern fridges). Dust-coated coils force the compressor to work harder as ambient kitchen temps rise. Takes 10 minutes with a coil brush ($12 hardware store).
  • Check the door gasket. Close the door on a dollar bill — if it slides out easily, the seal needs replacement.
  • Replace the water filter if you have an ice maker or water dispenser. Every 6 months regardless.

Dryer

  • Clean the full vent line. Lint builds up through winter; summer brings hotter laundry loads. Clogged vents are the #1 cause of dryer fires.
  • Inspect the vent hose for tears or kinks. If it’s plastic flex, replace with UL 2158A steel-flex (required by code).

Outdoor fridges and ice makers

  • Check water line connections for slow leaks. Winter-to-spring temperature swings can loosen compression fittings.
  • Clean outdoor unit exteriors — pollen, dust, and cobwebs block airflow on outdoor-rated fridges and ice makers.

Garage-installed appliances

  • Everything above applies doubly to garage appliances — they see the widest temperature swings and the most dust.

Summer — June through August

The goal: survive the hot months without emergency calls. East County and inland communities see the highest appliance stress June–September.

Refrigerator (especially garage fridges)

  • Don’t overpack. Air needs to circulate around items. An over-stuffed freezer, especially, can’t stay cold.
  • Check the temperature weekly. Fresh-food compartment should read 37°F; freezer 0°F. Summer heat stress can push temps 2–4°F higher on marginal units.
  • Listen for the compressor. If it’s running constantly (no on/off cycling), the unit is struggling with the heat — usually because of coil dust or a weakening compressor.

Ice makers

  • Expect higher demand — use rotates faster, so filter life shortens. Replace filters every 4 months instead of 6 during summer.
  • Watch for slow production. If the ice bin doesn’t fill, the water valve is weakening or the fill tube is partially frozen.

Dishwasher

  • Check inlet valve water pressure. Summer water usage in San Diego drops neighborhood pressure slightly — if your dishwasher takes forever to fill, that’s why.

Wine coolers and beverage centers

  • Verify ventilation clearance. Cabinets with blocked vents (towels stacked above, etc.) cause compressor overheating. Leave 2+ inches around the unit.

Fall — September through November

The goal: transition to cooler weather and pre-winter maintenance on heating-related appliances.

Dryer

  • Inspect the vent line one more time. Fall’s a good second checkpoint before winter starts heavier laundry cycles.
  • Clean the lint filter housing. Not just the filter itself — the cavity the filter sits in. Vacuum with a crevice tool. You’ll be surprised what accumulates down there.

Gas ranges and gas dryers

  • Inspect gas line connections. Tighten any flex-line connections that have loosened. If you smell gas at any point, shut off the gas valve and call.
  • Test igniters. Gas igniters weaken gradually over years. If the range takes more than 4 seconds to light or the oven takes 15+ seconds to ignite, the igniter is on its way out.

All appliances

  • Check cord and outlet condition. If any plug feels warm to the touch during operation, the outlet is failing — that’s an electrical hazard, not an appliance issue, and needs attention.

Winter — December through March

The goal: mild maintenance season. Most appliances run easier in winter — focus on small checks and plan any upgrades.

Refrigerator and freezer

  • Listen for defrost cycle operation. You should hear a soft pop/crackle occasionally as the defrost heater runs. If you never hear this and frost is building up, the defrost system has failed.

Washer

  • Check supply hoses. Rubber hoses should be replaced every 5 years — winter’s a good time because hose supply valves are usually easier to access when you’re not sweating.
  • Clean the door gasket (front-loaders). Mildew builds through winter when loads tend to be colder. Wipe the rubber seal with a bleach-diluted cloth monthly.

Dishwasher

  • Run a monthly hot-water cleaning cycle with a dishwasher cleaner packet. Winter produces less evaporation in the dishwasher, letting scale and grime build up on internal surfaces.

Holidays — extra load testing

  • If you host Thanksgiving or December holidays, your kitchen appliances get stress-tested. A dishwasher that marginally worked all year often fails the first time you run four cycles in one day.

Monthly habits (every month, all year)

  • Wipe the microwave interior. Splatter buildup causes arcing on the waveguide cover, which is a real fire hazard.
  • Clean the dishwasher filter. Five minutes. Remove, rinse, replace.
  • Wipe the refrigerator door gasket and inspect for tears.
  • Run the hot-water faucet at the sink closest to the dishwasher for 30 seconds before starting a cycle — primes the dishwasher with hot water.
  • Clean the dryer lint filter before every load. Yes, every load.

The single highest-value maintenance task

If you only do one thing: clean the dryer vent line annually. It’s the only maintenance task where skipping it creates a real fire risk, not just a performance issue.

When maintenance uncovers a problem

Half our service calls come from maintenance inspections — someone notices the fridge is warmer than usual during a coil cleaning, or the dryer seems hot after a vent check. That early-warning is worth more than any single DIY fix.

If you notice anything off during your seasonal check, book a diagnostic. $89 flat rate, credited toward any repair.
