Super El Niño Alert
Super El Niño summer forecast: prolonged 100°+ heat waves headed for SoCal — tune up before your AC fails. Forecasters warn of a 55% spike in AC breakdowns this summer — book preventative service before the wait list grows. Last summer’s heat wave left thousands of SoCal homes without AC for 5+ days — don’t be next. Schedule now. Avoid a $3,000 emergency replacement — an $89 tune-up catches the failures heat waves expose. Grid stress + 95°+ days = capacitors and motors fail first. Get ahead of it — book your inspection today.

Heat Advisory Warning!

Indoor Air Quality

The air inside your home can be 2–5x worse than outdoors.

EPA research shows indoor air typically holds 2–5 times more pollutants than outdoor air. Whole-home purifiers, UV sterilization, and high-MERV filtration fix that — at the source, for every room.

common pollutants circulate every time your HVAC runs

What you can't see, you're still breathing.

Dust mites, pet dander, pollen, mold spores, wildfire smoke (PM 2.5), VOCs from cleaners and furniture, bacteria, viruses. Modern, well-sealed homes trap all of it — and your standard 1" filter captures less than 10%. The rest cycles through your air, your furniture, your lungs.

Whole-home solutions installed at your HVAC system treat every cubic foot of air that passes through — far more effective than portable room units. Especially valuable for homes with allergies, asthma, immune-compromised members, or anywhere wildfire smoke is a recurring problem.

Why choose Canyon

What you actually get when you call us.

Whole-Home Air Purifiers.

Best for: allergens, VOCs, smoke. Installed in your HVAC, treat every cubic foot of air. Far more effective than portable units.

UV Light Systems.

Best for: bacteria, viruses, mold. UV-C germicidal lights neutralize pathogens at the air handler before they reach your living space.

High-MERV & HEPA Filtration.

Best for: dust, dander, fine particles. We size filters that fit your system without restricting airflow — so you get clean air without stressing equipment.

Air assessment

Free in-home walkthrough. We discuss specific issues (allergies, asthma, smoke, odors) and inspect your existing equipment and filtration.

Recommend

Targeted plan based on actual concerns — purifier, UV, filtration upgrade, or a layered combination. No upselling unneeded equipment.

Professional install

Whole-home equipment installed at the air handler. UV bulbs sized to your duct dimensions. Filter upgrades verified for static pressure.

Verify & maintain

Post-install verification, plus a maintenance schedule for bulb replacement, filter changes, and annual purifier service.

FAQ

Indoor Air Quality Solutions: questions homeowners ask us most.

The honest, in-plain-English answers we’d give a neighbor calling on the phone.

What IAQ products actually work?

The biggest measurable wins come from: media filters (MERV 11–13 cabinet filters), whole-home UV (sterilizes coil + airstream), and HEPA bypass systems for allergy households. We don’t sell ozone generators or anything else without independent efficacy data.

Will an IAQ system help with allergies and asthma?

Meaningfully, yes — especially the combination of MERV-13 filtration plus UV on the evaporator coil. For severe cases we’ll often add a dedicated HEPA bypass or a whole-home dehumidifier. We’ll match the system to your specific concerns, not just upsell the biggest package.

Can you install an IAQ system on my existing HVAC?

Almost always. Media filter cabinets, UV systems, humidifiers, and dehumidifiers all retrofit onto existing ducted HVAC systems with no equipment changes. Typical install runs half a day.
