Swap the evaporative cooler pads at invited La Puente homes before summer (2026-07-19)

Plenty of older La Puente and Valinda-edge homes still cool with rooftop or window evaporative coolers, and clogged mineral-crusted pads make them blow warm, damp air through the hottest weeks. Fresh pads and a basin clean restore real cooling for a fraction of an AC bill. Standard: Manufacturer evaporative cooler seasonal service practice; SDG 7 (Affordable and Clean Energy). Proof: Old-pad, cleaned-basin, and running-unit photos Method (Manufacturer evaporative cooler seasonal service practice; SDG 7 (Affordable and Clean Energy).): 1. Power off the cooler with the occupant and confirm it is reachable without a ladder above six feet — window and ground-mount units only. 2. Open the panels, remove the crusted pads, and clean scale and sediment from the basin. 3. Fit new pads cut to size and reseat the panels. 4. Restore power and water, run the cooler, and verify cool airflow and no leaks. 5. Photograph the old pads, the cleaned basin, and the running unit with date and GPS. Done when: Old-pad, cleaned-basin, and running-unit photos

This packet is not funded yet, so this figure is a proposed price and not money waiting in escrow. If a buyer funds it, approved proof settles that price onchain. If nobody funds it, approved proof earns provable credit toward the work instead of cash. You see which before you claim, never after.

Proof

Old-pad, cleaned-basin, and running-unit photos

This is exactly what gets it approved. Nothing settles without it.

How this work is done

A documented method, so this packet comes out the same whoever does it. Typically 60–120 minutes. Method of record: ASHRAE Level 1 energy audit

Bring

• tablet/clipboard
• tape measure
• light meter (lighting scope)
• clamp thermometer (refrigeration scope)
• 12-month utility bills
• camera
• ladder + spotter (high fixtures)

Steps

1. 1. Confirm the address; arrange a staff escort for mechanical/back-of-house.
2. 2. Photograph HVAC, lighting, envelope, and any in-scope systems.
3. 3. Inventory systems: HVAC type + age; lighting fixture count/type/wattage; refrigeration units; envelope condition.
4. 4. Summarize 12 months of utility use (kWh / therms) from the bills.
5. 5. Take the in-scope measurements (light levels, unit temperatures, seal condition).
6. 6. Rank no-cost/low-cost measures, then capital measures, with rough savings logic.
7. 7. Enter inventory, measurements, utility summary, photos, and the ranked measure list; sign.

If it does not match the plan

• Knob-and-tube, ungrounded or overheated wiring, scorched outlets, or a hot electrical panel -> STOP: do not operate the circuit; route to a licensed electrician and restrict use (NEC / fire hazard).
• Gas odor, or a combustion appliance with absent/blocked venting (backdrafting / CO risk) -> STOP: evacuate, ventilate, call the gas utility. The agent escalates, never relights or adjusts gas.
• Any live-electrical/gas hazard -> document, do not touch, flag for a licensed pro.
• Refrigeration unit out of food-safe range -> flag as both energy and food-safety risk.
• Suspected asbestos/lead in materials -> flag and stop.

What counts as done

• System inventory complete for the in-scope equipment
• 12-month utility use summary recorded
• In-scope measurements recorded with units
• Ranked no-cost/low-cost + capital measure list produced

Proof is measured against these, not judged by taste.
