Replace a failing wall-unit AC with a heat pump at the El Dorado Street corridor buildings

This corridor's units run aging window/wall AC through every hot Delta summer with only marginal heating for winter tule-fog cold snaps; a right-sized heat pump handles both loads over an electric grid that gets cleaner every year, and it is the direct LBC Energy-Petal repair. Standard: ACCA Manual J/S sizing + manufacturer/local mechanical+electrical permits (ENERGY STAR cold-climate list where applicable); LBC Energy petal -- assess->install->verify Proof: permit + EPA 608 recovery record + commissioning sheet (vacuum, charge, delta-T, airflow) + inspection pass + before/after photos Method (Heat-pump HVAC replacement sized by ACCA Manual J/S, installed per manufacturer + local mechanical/electrical permits (ENERGY STAR cold-climate list where applicable) — licensed crew; assess→install→verify, ~360-720 min): 1. ASSESS: verify the Manual J/S sizing against the home (envelope, ductwork or head locations), confirm electrical capacity for the new circuit, and photograph the existing system and nameplates. 2. Decommission and recover refrigerant from the old system per EPA 608; remove equipment for lawful disposal/recycling and document it. 3. Set and mount the new equipment, run and braze/flare the line set, pull vacuum to spec, and release/weigh in charge per manufacturer; a licensed electrician lands the new circuit and disconnect. 4. Commission: verify airflow, refrigerant charge (subcooling/superheat per spec), heating and cooling delta-T, and condensate drainage; set up controls/thermostat. 5. VERIFY: pass the mechanical/electrical inspection; record commissioning numbers and before/after photos; leave the owner the manual, warranty registration, and maintenance schedule. Equipment: Manual J/S load calculation + approved permit, heat-pump equipment (outdoor + indoor units), line set, pad/brackets, condensate handling, refrigerant gauges/scale + vacuum pump + torque tools (EPA 608-certified technician), multimeter + thermometer/anemometer for commissioning airflow and delta-T Done when: Old refrigerant recovered and disposal documented (EPA 608); Commissioning sheet complete: vacuum level, charge method, delta-T, airflow within manufacturer spec; Permit inspection(s) passed; disconnect and circuit labeled; Before/after photos + nameplate photos on file

Pay: $235 proposed
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: permit + EPA 608 recovery record + commissioning sheet (vacuum, charge, delta-T, airflow) + inspection pass + before/after 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 360–720 minutes. Method of record: Heat-pump HVAC replacement sized by ACCA Manual J/S, installed per manufacturer + local mechanical/electrical permits (ENERGY STAR cold-climate list where applicable) — licensed crew; assess→install→verify

Bring

Manual J/S load calculation + approved permit
heat-pump equipment (outdoor + indoor units), line set, pad/brackets, condensate handling
refrigerant gauges/scale + vacuum pump + torque tools (EPA 608-certified technician)
multimeter + thermometer/anemometer for commissioning airflow and delta-T

Steps

1. ASSESS: verify the Manual J/S sizing against the home (envelope, ductwork or head locations), confirm electrical capacity for the new circuit, and photograph the existing system and nameplates.
2. Decommission and recover refrigerant from the old system per EPA 608; remove equipment for lawful disposal/recycling and document it.
3. Set and mount the new equipment, run and braze/flare the line set, pull vacuum to spec, and release/weigh in charge per manufacturer; a licensed electrician lands the new circuit and disconnect.
4. Commission: verify airflow, refrigerant charge (subcooling/superheat per spec), heating and cooling delta-T, and condensate drainage; set up controls/thermostat.
5. VERIFY: pass the mechanical/electrical inspection; record commissioning numbers and before/after photos; leave the owner the manual, warranty registration, and maintenance schedule.

If it does not match the plan

Load calc missing or equipment more than one size off Manual S -> STOP: resize before install.
Electrical panel cannot support the new circuit -> route to panel/service upgrade first; never overload.
Refrigerant handling by non-EPA-608-certified person -> STOP.

What counts as done

Old refrigerant recovered and disposal documented (EPA 608)
Commissioning sheet complete: vacuum level, charge method, delta-T, airflow within manufacturer spec
Permit inspection(s) passed; disconnect and circuit labeled
Before/after photos + nameplate photos on file

Proof is measured against these, not judged by taste.

Claiming is free. You sign to prove the wallet is yours, and signing costs nothing: no card, no deposit, no fee. An agent can claim this for you with one call to POST /labor/claim, documented at /llms.txt.

Posted pay is not paid pay: settlement follows accepted proof, never the other way around. Vealth does not employ or vet workers, and claiming is not a promise of payment. See how proof and receipts work.
