What You’re Breathing In Can Be Harmful
Your indoor air may have 2-5x more pollutants than outdoor air, according to EPA research. At Canyon Air Systems, we can fix that. Our team installs whole-home purifiers, UV sterilization, and high-MERV filtration for clean air in every room.
- Available 24/7 for emergency calls — nights, weekends & holidays.

Do You Know What You’re Breathing?
Standard HVAC filters aren’t enough. They don’t capture small particulates that can circulate in your home and get into your lungs.
Common pollutants are easily trapped in a modern, well-sealed home. A typical 1” filter captures less than 10% of them. Whole-home solutions remove the following contaminants from circulating air:
- Wildfire Smoke
- Dust Mites
- Pet Dander
- Pollen
- Mold Spores
- VOCs
Indoor Air Quality (IAQ) is a concern for everyone living in Southern California.
Indoor Air Quality Solutions We Install
The HVAC team at Canyon can determine exactly what system you need. When you call us, here’s what you can get:
Whole Home
Air Purifiers
Compared to portable units, these offer superior filtration and treat every cubic foot of air.
UV Light
Systems
UV-C germicidal lights neutralize bacteria, viruses, and mold before they reach your living space.
HEPA
Filtration
High-MERV equipment captures fine particles without restricting airflow.
No-Surprise Indoor Air Quality Improvements
In four steps, you can have cleaner air to breathe and relief from allergies and asthma:
1st Step
Air Assessment
During a free in-home walkthrough, we’ll discuss specific concerns and inspect existing equipment.
2nd Step
Recommend
We’ll create a plan that includes a purifier, UV, or filtration upgrade, or a combination of options.
3rd Step
Professional Install
Whole-home equipment is installed at the air handler. UV bulbs are sized for ducts, and static pressure is measured with any filter upgrades.
4th Step
Verify & Maintain
Post-install checks are completed, and we set a schedule for filter changes, bulb replacement, or purifier service.
An IAQ system can almost always be installed in an existing HVAC unit, which takes about half a day. This includes humidifiers, dehumidifiers, and media filter cabinets.

AC Repair vs. AC Replacement
Air conditioners under 10 years old can almost always be repaired. Consider replacing an AC unit if:
- It's 10-15 years old
- Repairs cost about 50% of a new install
- The unit runs on R-22 refrigerant
To weigh your decision, we give you the honest math, with no pressure.
Other Ways We Improve Indoor Air Quality
Filtration and purification are important. However, we can optimize air quality in your home with these additional services:
Air Duct Cleaning
Using negative-pressure vacuums and rotary brushes, we remove the dust, debris, and allergens that collect in ducts.
Air Duct Sealing
On average, 20% of air is lost via unsealed ducts; a pressure test shows where air is leaking, so we can properly seal joints, seams, and boots.
Smart Thermostat Installation
Save on heating and cooling with remote temperature control (via an app), geofencing, performance monitoring, and alerts.
