Southern California has unique IAQ challenges that most homeowners don’t see coming - wildfire smoke season, coastal humidity, and sealed modern homes that trap pollutants inside.
According to the EPA, indoor air can be 2 to 5 times more polluted than outdoor air. In Southern California, this is compounded by sealed, energy-efficient homes that limit fresh air exchange - trapping dust, pet dander, VOCs from building materials, and recirculated HVAC debris inside. Homes without filtration upgrades accumulate contaminants every time the HVAC system runs.
Yes. During wildfire events - which the EPA now considers a major source of fine particle pollution in California, capable of reaching PM2.5 concentrations 10 times the healthy threshold indoors - fine smoke particles enter homes through HVAC air intakes, duct leaks, and building envelope gaps. Standard MERV 8 filters do not capture PM2.5 particles. MERV 13 filtration and whole-home air purifiers significantly reduce indoor wildfire smoke concentration. AIRONE assesses your current HVAC system to confirm it can support higher-efficiency filtration before upgrading.
Learn About Air Purifier Options →South Bay and Orange County homes experience elevated coastal humidity year-round. This creates favorable conditions for mold and mildew growth inside duct systems - particularly in older flex duct installations where condensation can accumulate. Contaminated ducts recirculate mold spores through every room of the home. Regular duct cleaning and duct sealing address both the biological contamination and the air leakage that allows moisture into the system.

AIRONE offers a complete range of whole-home IAQ solutions - all installed by licensed, EPA-certified HVAC technicians and sized for your existing HVAC system.
Installed in your air handler or ductwork, whole-home air purifiers treat every room simultaneously. Available in HEPA media, MERV 13 enhanced media, and electronic/PCO configurations - the right choice depends on your HVAC system and air quality goals.
Air Purifier Installation →UV-C germicidal lamps install inside the air handler near the evaporator coil and inactivate airborne bacteria, viruses, and mold spores before they recirculate through your home. Best used as a second-stage treatment alongside MERV 13 filtration.
UV Light Sanitizer Installation →AIRONE performs NADCA-standard duct cleaning using mechanical agitation and HEPA vacuum extraction. Recommended every 3 to 5 years, or sooner after renovation, rodent intrusion, visible mold, or occupying a previously owned home.
Duct Cleaning Service →Leaky ducts waste 20 to 30 percent of conditioned air and pull unfiltered air into your living spaces. AIRONE offers Aeroseal pressurized injection sealing and manual mastic sealing - both reduce duct leakage and improve IAQ system effectiveness.
Duct Sealing & Repair →Upgrading from a standard MERV 8 to a MERV 13 filter captures particles 0.3 microns and larger - including wildfire smoke, fine dust, and many airborne pathogens. AIRONE verifies your HVAC system airflow can support the upgrade before installing.
Learn About Filtration Upgrades →Not sure where to start? AIRONE’s licensed technicians assess your current HVAC system, ductwork condition, and filtration setup - then recommend the most cost-effective IAQ improvements for your home and budget. No obligation required.
Schedule a Consultation →Every IAQ service is performed by a licensed HVAC contractor with verified credentials - not a subcontractor or franchise technician.
AIRONE holds CA Contractor License #114807 (C-20) and EPA 608 certification. IAQ equipment installed without proper HVAC integration can reduce system airflow, void equipment warranties, or create new problems. AIRONE evaluates your full HVAC system before recommending any IAQ product - so installations work correctly from day one.
California Air Resources Board Title 17 regulations restrict VOC-containing HVAC treatments. AIRONE uses only CARB-compliant IAQ products and materials across all services - including duct cleaning treatments, sealants, and air purification systems. This matters for homeowners with children, respiratory conditions, or chemical sensitivities.
AIRONE has served over 500 residential and commercial clients across 126 cities in Los Angeles County, South Bay, and Orange County since 2020. Real experience with SoCal-specific IAQ challenges: extended wildfire seasons, coastal humidity, older duct systems in mid-century homes, and tight modern construction that traps indoor pollutants.
Every IAQ engagement starts with an honest assessment of what your home actually needs - not a product pitch.
Call (323) 471-1037 or use the form on this page to schedule a free IAQ consultation. A licensed AIRONE technician comes to your home - no dispatch fee for consultations, and the $89 diagnostic fee applies toward any repair if you proceed.
The technician evaluates your existing HVAC system capacity, current filtration setup, ductwork condition, and any visible IAQ issues. This step determines which IAQ upgrades are compatible with your equipment and which would provide the most benefit for your household.
You receive a clear, itemized written estimate for recommended IAQ services. AIRONE explains the expected benefit of each item so you can make an informed decision - or start with a single upgrade and add more later.
All IAQ equipment is installed by licensed, EPA-certified technicians using CARB-compliant products. After installation, the technician walks you through system operation, filter replacement schedules, and any follow-up service timelines.
AIRONE serves 126 cities across Los Angeles County, South Bay, and Orange County. A licensed HVAC technician will assess your home, explain your options, and provide a written estimate - no pressure, no obligation.

Understanding the difference between filtration, purification, UV sanitization, and duct services helps you choose the right combination for your home.
Portable room air purifiers treat a single room. Whole-home air purifiers install directly into your HVAC system and treat every cubic foot of air that passes through your home’s HVAC circulation. Technologies include HEPA media, MERV 13 enhanced media, electronic precipitation, and photocatalytic oxidation (PCO). AIRONE selects the right technology based on your existing HVAC equipment capacity and your household’s specific air quality concerns.
View Air Purifier Installation →UV-C germicidal lamps emit ultraviolet light at a wavelength that damages the DNA of airborne microorganisms - bacteria, viruses, and mold spores - rendering them unable to reproduce. The lamps install inside the air handler, typically near the evaporator coil or in the supply plenum. Single-lamp configurations target the coil surface; dual-lamp configurations add treatment of air passing through the supply plenum. UV light sanitizers work best alongside MERV 13 filtration - filtration captures particles, UV-C inactivates biology.
View UV Light Sanitizer Installation →NADCA defines the professional standard for duct cleaning. AIRONE follows this standard: mechanical agitation to loosen debris from duct walls, combined with HEPA vacuum extraction to capture and remove dislodged particles without releasing them into your home. AIRONE inspects registers, grilles, air handler components, and accessible duct sections before and after service to confirm cleaning effectiveness.
View Duct Cleaning Service →Aeroseal is a pressurized aerosol polymer sealant injected directly into the duct system. It travels to leak points and bonds to seal gaps from the inside - reaching areas physically inaccessible for manual sealing. Aeroseal provides measurable before-and-after leakage data. Manual mastic sealing uses a brush-applied compound to seal visible seams, joints, and connections in accessible duct runs. AIRONE recommends the appropriate method based on your duct system layout, accessibility, and leakage profile.
