Sun Valley was called Roberts, then Roscoe, before residents voted in 1950 to rename it Sun Valley, and the name fits. It’s one of the hotter, drier parts of the east Valley, stretching from industrial corridors near the 5 freeway to horse properties toward Shadow Hills and La Tuna Canyon. We connect Sun Valley homeowners and business owners with independent, licensed HVAC contractors.
Gravel Yards, Dust and Your Outdoor Unit
Sun Valley has long been home to gravel pits, recycling yards, landfills and industrial sites. On windy days, fine dust from these areas settles on everything, including the coil of your outdoor AC unit. A coated coil can’t release heat well, so the system runs longer and works harder. A spring coil cleaning and a monthly filter check go a long way here.
If you live near an industrial area, consider a higher-rated filter that your system can handle, and make sure return ducts are sealed so the system isn’t pulling dusty garage or attic air into the house.
Street Flooding and Equipment Placement
Parts of Sun Valley are known for streets and yards that flood in heavy rain, because the area was built without a full storm drain system. Standing water can damage the electrical parts of an outdoor unit sitting on a low pad. When you replace equipment, ask whether it makes sense to set the new unit on a raised pad or stand, and keep drainage paths around it clear.
Near the Airport and the Hills
Southeast Sun Valley sits close to Hollywood Burbank Airport, and many homeowners keep windows shut to block noise, which puts more demand on the AC in summer. To the northeast, horse properties and canyon homes near La Tuna Canyon see more dust and, during fire season, smoke from the Verdugo Mountains, as in the 2017 La Tuna Fire.
Typical Sun Valley Calls
- AC losing capacity on hot days: often a dust-clogged outdoor coil. See AC repair and maintenance.
- Replacing a unit damaged by water or age: new equipment on a raised pad where needed.
- Shops, warehouses and yards: rooftop and split systems through commercial HVAC.
- Dust and smoke filtration: air quality upgrades.
Heating Season in Sun Valley
Fine dust from nearby gravel and recycling yards clogs furnace filters and heat pump coils, so change the filter before turning on the heat and rinse the outdoor coil if you have a heat pump. If your outdoor unit sits on a low pad in a flood-prone yard, have it checked after heavy rain before relying on it for heat. See heat pumps and tune-ups.

Common Questions
How often should my outdoor coil be cleaned in Sun Valley?
At least once a year, ideally in spring before the heat arrives. Homes near gravel yards or busy industrial streets may need it more often. With the power off, you can gently rinse the coil with a garden hose between professional cleanings. Never use a pressure washer.
My yard floods when it rains. Is my AC unit at risk?
It can be. Water reaching the electrical components can cause damage and safety problems. A contractor can raise the unit on a taller pad or stand and check its wiring after a flood. Don’t run a unit that has been sitting in water until it has been inspected.
Who handles permits in Sun Valley?
Sun Valley is in the City of Los Angeles, so permits come from LADBS, and electricity comes from LADWP. A licensed contractor should pull the permit for you.
