Clean ducts and good indoor air quality go hand in hand. Valley HVAC Network connects you with independent, licensed local HVAC professionals who handle duct cleaning, sealing, and indoor air quality improvements throughout the San Fernando Valley.
Signs Your Ducts or Air Quality Need Attention
- Visible dust buildup around vents or noticeably more dust settling in your home
- Musty or stale odors when your HVAC system runs
- Uneven airflow between rooms, often a sign of duct leaks or blockages
- Increased allergy or respiratory symptoms at home
- Recent wildfire smoke exposure — ash and smoke particles can settle in ductwork and recirculate
Services We Help Connect You With
- Duct cleaning and sanitizing
- Duct sealing and repair (leaky ducts waste energy and pull in attic or crawlspace dust)
- Air filtration upgrades (HEPA and high-MERV filter systems)
- Whole-home air purifier installation
- UV light and germicidal system installation
Why This Matters in the Valley
San Fernando Valley homes deal with dust, seasonal wildfire smoke, and pollen more than many areas, and older homes with original ductwork often have leaks or buildup that make air quality worse than it needs to be. Addressing ducts and filtration together often gives the best results, since clean air moving through leaky or dirty ducts still ends up dirty.
Do You Actually Need Duct Cleaning?
Not always. The U.S. EPA says routine duct cleaning isn’t necessary for most homes, but it is worth considering when:
- You can see mold growth inside the ducts or on other HVAC parts
- There’s evidence of rodents or insects in the ducts
- Dust and debris are blowing out of the vents
- You’ve had a renovation, or smoke or fire damage
A good contractor will inspect first and tell you honestly whether cleaning, sealing or better filtration is the real fix.
Duct Sealing: Often the Bigger Win
According to ENERGY STAR, about 20 to 30 percent of the air moving through a typical home’s ducts is lost to leaks, holes and poorly connected ducts. In many Valley homes those ducts run through hot attics, so leaks waste cooling, pull in attic dust and leave some rooms uncomfortable. Sealing and insulating ducts can make a noticeable difference.
Wildfire Smoke and Your HVAC
- Use the highest-rated filter your system can handle. MERV 13 is often recommended for smoke, but check with a technician first, because some older systems can’t handle the added resistance.
- During smoky days, keep windows closed and set the system to recirculate indoor air.
- Replace the filter after a heavy smoke event.
- Consider a whole-home air cleaner if smoke or allergies are a regular problem.
Watch Out for “Too Good to Be True” Duct Cleaning Deals
Very cheap “whole-house” duct cleaning offers are often used to get in the door and upsell. Ask for a written scope of work, what’s included and the final price before work starts.
Common Questions
How often should ducts be cleaned?
There’s no set schedule. Clean them when there’s a specific reason, such as mold, pests, heavy dust or after construction or smoke damage.
Will duct cleaning help my allergies?
It can help if the ducts are actually dirty, but better filtration and sealing duct leaks often make a bigger difference. An inspection will tell you which one you need.
How much does duct cleaning cost?
It depends on the size of your home, the number of vents, how easy the ducts are to reach, and whether repairs or sealing are needed. Be wary of very low advertised prices that grow once the crew arrives. Ask exactly what’s included before you agree.
