Replace a gas furnace with a heat pump, the 1900-2000 block of Melrose Ave, South Linden

Gas furnaces in the 1900-2000 block of Melrose Ave, South Linden's older housing burn fossil fuel for every hour of heat; a right-sized heat pump is the direct Energy-petal repair, and it cools too — which these units mostly can't. Standard: Heat-pump HVAC replacement — ACCA Manual J/S sizing, manufacturer + local mechanical/electrical permits (LBC Energy petal). SDG 7. Proof: Before photos incl. old-equipment nameplates + refrigerant-recovery record + Commissioning sheet (vacuum, charge method, delta-T, airflow) + Permit inspection pass reference + After photos of the installed system and disconnect labeling Method (Heat-pump HVAC replacement — ACCA Manual J/S sizing, manufacturer + local mechanical/electrical permits (LBC Energy petal). SDG 7.): 1. Verify the Manual J/S sizing against the home and photograph the existing furnace and nameplates; confirm the permit and electrical capacity before work. 2. Recover refrigerant from any old unit per EPA 608 and remove equipment for documented disposal. 3. Set the new heat pump, run the line set, pull vacuum to spec and charge per manufacturer; a licensed electrician lands the circuit and disconnect. 4. Commission: verify charge, airflow, heating/cooling delta-T and condensate; set up the thermostat. 5. Pass the mechanical/electrical inspection and photograph the commissioning readings and finished installation. Done when: Before photos incl. old-equipment nameplates + refrigerant-recovery record + Commissioning sheet (vacuum, charge method, delta-T, airflow) + Permit inspection pass reference + After photos of the installed system and disconnect labeling

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

Before photos incl. old-equipment nameplates + refrigerant-recovery record + Commissioning sheet (vacuum, charge method, delta-T, airflow) + Permit inspection pass reference + After photos of the installed system and disconnect labeling

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. 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. 2. Decommission and recover refrigerant from the old system per EPA 608; remove equipment for lawful disposal/recycling and document it.
3. 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. 4. Commission: verify airflow, refrigerant charge (subcooling/superheat per spec), heating and cooling delta-T, and condensate drainage; set up controls/thermostat.
5. 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.
