Glendale homes and what they put their ducts through
Glendale is a city of hills. Its north end climbs into the Verdugo Mountains and the canyons that cut into them, where streets like those in Chevy Chase, Glenoaks Canyon and Verdugo Woodlands wind past homes built on sloped lots. The City of Glendale runs a vegetation management program for these hillside and canyon communities because they sit beside open brush in High and Very High Fire Hazard Severity Zones.
For a duct system, living next to the brush means more of everything that blows in. Dry hillside dust, pollen and the occasional wildfire smoke event all end up at the return grille. Hillside homes also tend to have unusual layouts: split levels, long duct runs to far bedrooms, and air handlers squeezed into a garage, closet or crawlspace. Long runs with many turns give dust more places to settle.
Rossmoyne and Glendale’s period revival homes
Farther south, Glendale’s older neighborhoods have their own character. The Rossmoyne Historic District is the city’s largest, with 503 homes in Spanish Colonial Revival, Tudor Revival and French-inspired styles. Development there began in 1923 and was mostly complete by 1950, according to the City of Glendale. Like most homes of that era, these houses were designed without central air. Heating and cooling were retrofitted later, often with ducts in the attic or under the floor, and sometimes with return air pulled from a hallway or closet that collects household dust.
Apartments and condos in South Glendale and downtown
Glendale also has plenty of multifamily housing. Starting in the 1980s, many single-family lots in South Glendale were replaced with apartments and condominiums, and newer mid-rise and luxury buildings have gone up downtown near the Americana at Brand. These buildings often have compact, closet-mounted HVAC units with short duct runs and shared laundry rooms on each floor.
Heat, wind and long run times
Glendale sits inland, and summers are hot. The city’s record high is 115 degrees, set in September 2020. Fall brings Santa Ana winds that can reach 70 miles per hour and gust even harder through mountain passes and canyons. All of that means Glendale air conditioners run for long stretches and pull a lot of outside dust into the home. If you notice more dust than usual around your vents, read our guide on signs your air ducts need cleaning, or our article on air ducts after wildfire smoke if smoke has been a problem.
What our air duct cleaning covers
Our air duct cleaning service begins with an inspection of the registers, returns and reachable ductwork. We then remove dust and debris from accessible supply and return lines, grilles and registers, using professional equipment such as HEPA-filtered negative-air vacuums, agitation tools and inspection cameras where appropriate. For homes with odor problems or past rodent activity, which is not unusual near open hillsides, air duct sanitizing is available after cleaning.
The U.S. EPA notes that duct cleaning has not been shown to prevent health problems, and recommends it in specific situations: visible mold growth, vermin infestation, or excessive dust and debris released into the home. We use those same guidelines when we tell you whether a cleaning makes sense.
Other services for Glendale properties
Attic insulation. Hillside homes and older period revival houses often have aging or rodent-damaged attic insulation. Our attic insulation service removes old material and installs new, and it is easiest to do around the same time as a duct cleaning.
Dryer vents. In South Glendale apartment buildings, shared laundry rooms and stacked units can have long vent runs. We handle dryer vent cleaning and dryer vent repair for single homes and whole buildings.
HVAC and AC cleaning. With Glendale’s hot summers, a dirty coil or blower makes a big difference. Our HVAC cleaning and AC cleaning cover accessible equipment components.
Chimneys. Many of Glendale’s older homes have fireplaces. Chimney cleaning clears soot and creosote before the cooler months.
