  • Took photos of any pre-existing damage to work area and equipment (including interior and exterior of equipment)
  • Furnace unplugged
  • Gas shut off

Equipment

Removing Old

  • Service valves closed so refrigerant oil won’t stain driveways/walkways or kill grass
  • Blew out condensation lines with nitrogen until came out clear
  • Burner compartment in upward position when carried out
  • Evaporator coil and drain pans drained before removal

Unboxing New

  • Equipment received as ordered: undamaged, no missing parts
  • Contacted distributor or office so they can contact distributor if any equipment was damaged
  • Located all paperwork and set it aside for customer

Condenser Unit

  • Evacuate any refrigerant still present in the system
  • Removed vent pipe and support it if necessary to prevent damage to flashing or another vent connection
  • Ground where unit will sit is level/secure
  • Unit is out of direct sunlight for maximum efficiency
  • Unit is away from gutters, downspouts, and outlets and won’t have water pouring down on it directly from roof
  • Unit is 6-10 inches away from home (or per manufacturer specifications, on both sides if in corner), fences, plants, and there’s plenty of clearance around unit for air flow
  • Unit is at least 3ft away from gas/electric meter
  • Pad is level
  • Condenser fits pad properly

Plenums

Not Replacing

  • Check widths of furnace and coil to make sure they match and plenums are correct

Replacing

  • Remove any existing driers, and remove electrical whip disconnect box
  • Disconnect low voltage to condenser
  • No air tights with dampers installed on the returns, only supplies 
  • Make sure all dampers are locked in the open position

Evaporator Coil

  • Clear condensate drain with nitrogen
  • Clear emergency drain with nitrogen
  • Flush line set from upstairs to outside to remove any non-compatible oils
  • Make sure condensate drain has fall. Back shelf should be about a half inch higher than front shelf, pitched towards front so bottom tray can run out drain hole and water that collects can run out

Clearances

  • Copper not in the way of the drain
  • Vent not in the way of the drain
  • Copper, drain, and vent won’t interfere with each other
  • All drain accessory switches are clear of filter racks and obstructions

Drip Pans

  • Clean and free of cracks and rust
  • No standing water, odors, or leaks
  • Drain is clear and free of fungi

Duct Work

  • No kinks, gaps, cracks, or leaks, and free of obstructions
  • Strapped and hung correctly
  • Air distribution balanced
  • Supply and return vents are open and clean

Disconnect

  • Power to air conditioning unit shut off and double checked no currents are going through wires
  • If disconnect box is present, has an on/off switch and cover
  • Replaced or installed disconnect box if needed
  • Disconnect box is easily accessible and within sight of the unit. Note: You should be able to touch the unit and disconnect switch at the same time and kill power without having to reach across the top of the unit
  • Disconnect box is high enough to avoid water and snow fall line and won’t interfere with electrical system. (See local electrical codes.)
  • Line, load, and ground wires are attached correctly and are snug and secure under lugs and screws
  • Rings and screws were all reattached and are tight
  • Inside cover and disconnect have been put back inside disconnect box
  • Sealed around box so no moisture and bugs can get in
  • Opened and closed the box a few times to make sure that the lid functions correctly.

Brazing

Safety Precautions

  • Power is turned off both at disconnect and breaker
  • Flammable materials like leaves have been removed from around the area
  • Have clear and easy access to fire suppression tools like a fire extinguisher and/or charged water hose
  • If brazing close to a wall, the wall has wet rags or wetrag putty around where the lines go into the home (hot copper can transfer heat into the wall igniting black board insulation and other flammable materials).
  • Water nearby to resaturate rags if needed
  • Safety glasses and gloves are being worn

Preparation

  • Tanks are full and leak checked
  • Pipes are dry and clean
  • Removed dirt, oil, corrosion, or residue from pipes and fittings. Cleaned pipes/fittings with sand/mesh cloth an inch or two above where you plan to cut pipe until shiny. This will help to avoid getting residue inside pipe. Then rub residue from mesh cloth off. 
  • Removed burrs that occur around the lip of the pipe after cutting until lip is completely smooth when you press finger into pipe. 
  • Double checked that nothing was inside pipes
  • Checked gauges were closed and connections are tight

Acetylene

  • Open only to about a quarter of a turn so it’s easy to turn off tank in emergency
  • Set secondary gauge to 5psi when valve is opened

Oxygen

  • Tank pressure set to around 1600psi
  • Set secondary gauge to 10psi

Refrigerant lines

  • Removed valve cores, valve caps, and schrader cores both on high and low side
  • Wrapped service valves with wet rags and ensured rags were extremely wet (but not dripping) and secure around valves
  • Flow nitrogen at 2-5 psi while brazing so pipe doesn’t flake off inside.
  • Left service port open on opposite side brazing
  • Flame is a controlled reducing flame, not pointed into the joint and pointed away from the valve
  • Started braising at bottom of joint

Piston Coil

  • Proper piston has been installed
  • New piston size recorded if changed
  • Installed in the right direction
  • Stub out seals installed correctly
  • Tightened correctly

Evaporator Coil

  • Strapped line set so can’t pop out while brazing if loose
  • TXV, TXV bulb, suction line, and thermostatic expansion valve protected
  • Put wet rag under area being brazed in case braze falls into plastic pan underneath
  • Replaced cover plate
