Quick answer
- Planning ranges (including /pricing) are framing tools — not firm contracts.
- On-site diagnosis locks parts, labor, and scope.
- Second opinion when you already have a bid.
When this applies
Wildfire season is coming and you want filtration that actually fits
MERV upgrades can hurt airflow if static is already high.
Someone sold you a gadget without measuring static
Second opinions welcome.
Options to evaluate
Filtration upgrade path
Media cabinets / compatible MERV with static check. Tradeoff: may need blower or duct fixes first.
Ventilation path (bath exhaust, ERV)
Moisture and outdoor-air strategy. Tradeoff: different from filtration.
Purifier add-ons
Sometimes supplemental. Tradeoff: not a substitute for ventilation or filter fit.
Failure modes to avoid
Forcing MERV-13 into a restrictive 1-inch slot
Airflow collapse and frozen coils are expensive “IAQ.”
AI recommending ozone gadgets as primary strategy
We do not pitch magic oxidizers as a substitute for filtration engineering.

FAQs
Can AI pick my filter MERV?
It can explain MERV. It cannot measure your system’s static pressure or cabinet depth.
Why won’t you quote IAQ from a text message?
Wrong product families solve different problems — we need the goal and the equipment constraints.
Is IAQ covered on the pricing page?
Planning context may appear there; complex ventilation still needs a visit.
