Understanding Your Home's Air
What Indoor Air Quality
Means for Your Home
Indoor air quality (IAQ) refers to the air quality within and around buildings and structures, especially as it relates to the health and comfort of the people living there. It’s something most homeowners don’t think about until a problem arises.
The EPA estimates that indoor air can be 2 to 5 times more polluted than outdoor air — even in a city like Los Angeles. This is because modern homes are built to be energy-efficient, which also means they trap pollutants inside.
Your HVAC system plays a central role in your home’s air quality. It circulates air throughout your home, and without proper filtration and maintenance, it can actually spread contaminants rather than remove them.
Good to Know
In Southern California, where we run our HVAC systems year-round, the quality of the air being circulated directly impacts your family's comfort and health.
Common Indoor Air Pollutants
Dust & Allergens
Common household particles that accumulate over time
Pet Dander
Microscopic skin flakes from cats, dogs, and other pets
Mold Spores
Airborne fungi that thrive in humid conditions
VOCs
Volatile organic compounds from household products
Unlike outdoor air that naturally disperses, indoor pollutants can build up over time if not properly addressed through filtration and ventilation.

Air Duct Cleaning
Professional Air Duct Cleaning
for a Healthier Home
Air duct cleaning can be beneficial for improving your home’s air quality — but it’s not always necessary. We believe in being honest about when it will actually help, and when your money is better spent elsewhere.
What Air Duct Cleaning Actually Does
Professional duct cleaning removes accumulated dust, debris, and contaminants from your HVAC ductwork. Over time, these materials can build up and affect both your air quality and system efficiency.
When ducts are clogged with debris, your HVAC system has to work harder to push air through, potentially increasing energy costs and reducing equipment lifespan. Clean ducts allow for better airflow and more consistent temperatures throughout your North Hollywood home.
When Duct Cleaning Is Beneficial
- Visible dust buildup around vents and registers
- Recent home renovations or construction
- Family members with allergies or respiratory issues
- Homes with multiple pets
- Moving into a new home
- Musty or stale odors when HVAC runs

Know the Signs
Common Signs of Poor
Indoor Air Quality
Wondering if your home’s air quality might need attention? Here are some common indicators that many Los Angeles homeowners experience.
Excessive Dust Buildup
If you're dusting frequently but surfaces get dusty again quickly, your air filtration may need attention.
Allergy or Asthma Flare-Ups
Increased respiratory symptoms when indoors can indicate poor air quality affecting your family's health.
Musty or Stale Odors
Persistent smells that won't go away might indicate mold, mildew, or inadequate ventilation.
Uneven Airflow
Hot and cold spots throughout your home can signal ductwork issues affecting air distribution.
Lingering Pet or Cooking Smells
If odors stick around longer than they should, your home may not be getting enough fresh air circulation.
Humidity Issues
Air that feels too dry or too humid can affect both comfort and air quality, encouraging mold or dust mites.
Remember: These signs don’t always mean you have a serious problem. Sometimes simple solutions like changing your air filter more frequently can make a big difference. We’re happy to help you figure out what’s actually going on.

How It Works
How Indoor Air Quality Systems
Work Together
Understanding how these components work with your existing HVAC system helps you make informed decisions about improving your home’s air quality.
01
Air Filters & Filtration Levels
Your HVAC filter is your first line of defense. MERV-rated filters capture different particle sizes — higher MERV means finer filtration. We can help you choose the right level for your system and needs.
02
Air Purifiers & UV Solutions
These systems work alongside your HVAC to neutralize what filters can’t catch — bacteria, viruses, and VOCs. UV lights installed in your ductwork sterilize air as it passes through.
03
Ductwork's Role in Circulation
Your ducts are the highway for conditioned air. Clean, properly sealed ducts ensure that filtered air reaches every room efficiently without picking up contaminants along the way.
04
The Importance of Proper Airflow
All these systems work best when your HVAC has proper airflow. Clogged filters, blocked vents, or ductwork issues can reduce effectiveness of even the best IAQ equipment.
The Key Is Working Together
IAQ upgrades aren't about adding as much equipment as possible — they're about creating a balanced system that works with your existing HVAC to deliver cleaner air efficiently. We'll help you find the right combination for your home and budget.
Built for LA
Designed for
Southern California Living
Los Angeles presents unique indoor air quality challenges that generic solutions don’t address. Our IAQ recommendations are specifically tailored for the conditions we face here.
Dust & Outdoor Air Pollution
LA's unique geography traps pollutants. Santa Ana winds bring dust and particulates that find their way into homes, making quality filtration essential.
Wildfire Smoke Considerations
During fire season, outdoor air quality can plummet. Proper filtration and sealed ductwork help keep smoke particles outside where they belong.
Older Duct Systems
Many North Hollywood and LA homes have ductwork from the '60s, '70s, and '80s. These systems may have accumulated decades of dust and debris.
Year-Round HVAC Usage
Unlike other climates, we use our heating and cooling systems almost daily. This constant circulation means your air quality system never gets a break.
