Garage laundry is standard in San Diego. Most tract homes from the 1950s onward, from Clairemont to Mira Mesa to Eastlake, put the washer and dryer against a garage wall. Manufacturers publish location limits for these machines, and the numbers they print are about cold. San Diego garages rarely get that cold, but the inland ones get very hot, and that has its own effects even though the manuals cited here don't give a maximum.
What the manuals say
- •Whirlpool top-load washer (W10150593A): Do not store or operate your washer in temperatures at or below 32°F, and don't install or store it where it will be exposed to the weather.
- •Whirlpool commercial front-load washer (CHW9050/CHW9060): It sets a similar limit, no operation below 32°F, and gives the reason: water can remain in the washer and cause damage in low temperatures.
- •Whirlpool 29-inch electric dryers (W10617663C): Don't operate the dryer at temperatures below 45°F, because the automatic cycle may not shut off and drying times can increase. The guide also notes that local codes may restrict dryers in garages, and it allows a maximum floor slope of 1 inch, with an extended feet kit for steeper floors.
The dryer's limit is higher than the washer's. A garage that stays above freezing can still be too cold for the dryer's automatic cycles.
Cold: when it actually matters here
Coastal garages in Point Loma, Pacific Beach or Coronado almost never approach these limits. Inland valleys are different. Winter nights in El Cajon, Santee, Rancho Bernardo, Poway and the backcountry can get cold enough that an uninsulated garage dips into the 40s by morning. That's below the Whirlpool dryer's 45°F limit, and an early-morning load may run long or keep tumbling past dry. Freezing temperatures inside a garage are uncommon in the metro area but possible in higher, colder spots east of the city.
Heat: the bigger issue in inland garages
A closed garage with a west-facing door in El Cajon, La Mesa or Rancho Bernardo can get very hot during a summer heat wave or a Santa Ana event. The manuals cited here don't publish a maximum temperature, so treat these as practical observations rather than specs:
- •Dryers work harder. The dryer is pulling hot air in and pushing it out through a vent that may already be near its limit (see dryer vent maximum length). Thermal fuses and high-limit thermostats trip more often when airflow is marginal.
- •Rubber ages faster. Fill hoses, door boots and drain hoses exposed to repeated heat stiffen and crack sooner. Braided stainless fill hoses hold up better than plain rubber.
- •Dust. Santa Ana winds blow fine dust under garage doors, which collects on lint screens, controls and the dryer's intake.
- •Electronics. Control boards in the hottest garages see more heat stress than those indoors.
Ventilating the garage during hot afternoons and running loads in the morning or evening helps, and it fits SDG&E's time-of-use pricing, where the 4–9 pm window is the most expensive time to run a dryer.
Garage floors
Garage slabs slope toward the door for drainage. Whirlpool's dryer guide allows a maximum 1-inch slope across the machine. Front-load washers are even more sensitive to an uneven floor; see front-load washer floor requirements. If your garage sits low or has taken on water in a storm, elevating appliances above flood level covers raising the machines.
How to check your garage
- Put a min-max thermometer near the machines for a week in summer and a week in winter.
- Compare the low with 32°F for the washer and 45°F for the dryer.
- Note the summer highs and whether the garage gets direct afternoon sun.
- Check the floor under each machine with a level.
- For a gas dryer, confirm its base sits at least 18 inches above the floor, as the Whirlpool gas dryer guide requires.
- Look at the fill hoses for bulges, cracks or stiffness, and replace rubber hoses showing their age.
What we check on garage-laundry service calls
- •Fill hoses and inlet valve screens, which also pick up scale from San Diego's hard water.
- •Leveling and the condition of the washer's suspension, since sloped garage floors make machines walk.
- •Dryer vent airflow and the thermal fuse, especially after hot spells.
- •Dust and lint around the dryer motor and controls.
See our washer repair and dryer repair pages for the full list of what we fix. If your garage dryer is gas, also read gas dryer installation requirements.
Work for other trades
- •Adding a circuit in a garage is work for a licensed electrician; insulating or ventilating it is a contractor's job.
- •Moving water lines, or disconnecting gas to move a gas dryer, is work for a licensed plumber or gas contractor.
- •Local code may restrict garage laundry changes, so ask your building department before moving machines into or within a garage.
Frequently asked questions
Is it fine to keep my washer and dryer in the garage in San Diego? Yes, it's a very common setup here. The cold limits rarely come into play on the coast, but inland owners should watch winter mornings and summer heat.
Will a hot garage damage my washer or dryer? The manuals cited here don't set a maximum garage temperature. Heat mostly shortens the life of hoses and rubber parts and adds strain to a dryer with a long or partly blocked vent.
