Install a quiet bathroom ventilation fan in an invited Rodeo home that has none

Many small Rodeo homes have no working bath fan, so moisture builds into mold in the same rooms where families already worry about outdoor air. A modern quiet fan on a humidity switch removes moisture at the source. This is the natural next rung after the filter route finds homes with condensation problems. Standard: ASHRAE 62.2 residential ventilation minimums; HUD healthy homes moisture control; SDG 3 (Good Health and Well-Being). Proof: Install-sequence photos plus airflow verification Method (ASHRAE 62.2 residential ventilation minimums; HUD healthy homes moisture control; SDG 3 (Good Health and Well-Being).): 1. Confirm with the occupant that an existing fan opening or accessible ceiling route to an exterior wall or soffit exists. 2. Cut power at the breaker and mount the new quiet fan unit in the ceiling opening. 3. Duct it to the exterior with smooth rigid duct and a backdraft damper — never into the attic space. 4. Wire to the existing switch circuit, restore power, and verify airflow with a tissue test. 5. Photograph the ducted run, the finished fan, and the working tissue test. Done when: Install-sequence photos plus airflow verification

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 45–90 minutes. Method of record: ASHRAE 62.1 + EPA IAQ / moisture baseline

Bring

• CO2 monitor
• PM2.5 monitor
• temp/RH meter
• moisture meter (mold/moisture scope)
• GPS/address
• camera

Steps

1. 1. Confirm the room/unit and address; coordinate to sample during normal occupancy where relevant.
2. 2. Photograph the space and any staining/damp/mold.
3. 3. Place the monitor in the occupied zone; log CO2 over >=1 occupied hour.
4. 4. Record PM2.5, temperature, and relative humidity.
5. 5. For moisture/mold scope, take moisture-meter readings at affected vs baseline areas and estimate visible mold area.
6. 6. Note ventilation type and any obvious deficiencies.
7. 7. Enter the logs, readings, extent notes, photos into the proof record; sign.

If it does not match the plan

• Carbon monoxide > 9 ppm sustained in an occupied space, or any audible CO alarm -> STOP: life-safety hazard. Evacuate, ventilate, and call the gas utility / fire department now. The agent escalates immediately, never sources the leak (NIOSH/ASHRAE CO).
• CO2 sustained > 2000 ppm in an occupied space -> flag acute under-ventilation: recommend increasing outdoor air and reducing occupancy immediately and report to the facility manager (well above the 1000 ppm ASHRAE 62.1 comfort flag).
• CO2 sustained > 1000 ppm -> flag under-ventilation vs ASHRAE 62.1.
• PM2.5 > 35 ug/m3 (24-hr, EPA NAAQS) -> flag elevated particulate; > 55 ug/m3 -> recommend occupants limit exposure / use filtration now.
• Visible mold > 10 sq ft OR active water intrusion -> document only, do not disturb; route to a licensed remediation pro (EPA mold guidance); occupants with respiratory symptoms routed to relocate.

What counts as done

• CO2 logged over >=1 occupied hour
• PM2.5, temperature, and RH recorded
• Moisture readings + visible-mold extent recorded (moisture scope)
• Timestamped photos + address confirm

Proof is measured against these, not judged by taste.
