Indoor air quality
in the Bay Area
Wildfire season changed what Bay Area homes need from an HVAC system. A one-inch filter from the hardware store does close to nothing against smoke particles — proper filtration is a system, not a purchase.

What we solve
Air problems worth fixing.
These are the complaints we hear most, and what actually sits behind them.
Smoke gets in during fire season
Standard filters miss fine particulates entirely. A deep media filter or MERV-13 upgrade changes this measurably.
Allergies worse indoors than out
Return-side duct leaks pulling in crawlspace air, plus filtration that isn't catching pollen.
Rooms feel stuffy and stale
Modern tight construction without mechanical ventilation. Fresh air needs a path in, not just filtration.
Condensation and musty smell
Humidity sitting where it shouldn't. Common in coastal homes and converted basements.
Pricing
Priced after diagnosis, not before.
Parts and labor for indoor air quality vary too much by brand and fault to publish a flat rate honestly. A technician diagnoses the issue on site and gives you the exact price in writing — nothing starts until you approve it, and the diagnostic fee is applied to the repair.

Questions
Before you call.
Will a better filter hurt my system?
It can, if the ductwork can't handle the added resistance. That's why we measure static pressure first rather than jamming in the thickest filter that fits.
Do portable air purifiers help during fire season?
Yes, in a single room. For the whole house, filtration at the HVAC system does far more per dollar.
How often should filters be changed?
One-inch filters every 60 to 90 days, deep media filters every 6 to 12 months. During heavy smoke, check monthly.
