Changeout day: crane, installers, electrician sub, one start time

A residential changeout is a one-day dance with four partners who each have a different boss. Your two installers work for you. The crane operator is booked by the hour through the rental yard. The electrician is a sub you use for the disconnect and whip. And the whole day only works if all four hit the driveway inside the same twenty-minute window in the morning.

Most of the time you set that up the night before with a group text. You post the address, you type “8am start,” everyone thumbs it up, and you go to bed thinking it is handled. Then at 8:40 the crane is idling in the street, your installers are standing around the old condenser they cannot legally disconnect, and the electrician is texting “running behind, be there by 9:30.” Nobody did anything wrong. The start time just never lived anywhere everyone could see it at 6am, so one player read it loose and the whole day slid.

If you run changeouts, you know this is not rare. It is the version most installers have lived. The fix is not another reminder text. It is making the day’s plan into something that holds, and closing the loop with the one player who is not on your payroll. This is core proof and getting paid work: a job that runs on schedule and gets documented as it goes closes clean and bills without an argument.

The run of show, hour by hour

A clean changeout has a spine. Write it down once and it stops living only in your head.

7:50, everyone on site. Installers, crane, electrician. The crane and the sub are the two you do not control, so they are the two the schedule has to nail.

8:00 to 8:30, disconnect and pull. Electrician kills power and pulls the whip. Installers recover refrigerant, cut the lineset, and rig the old condenser. Photo the nameplate of the old unit before it leaves the pad, model and serial, because that is the number the warranty desk and the customer file both want later.

8:30 to 9:00, crane sets the old out and the new in. This is the expensive window. The crane is billing whether it is lifting or waiting. Old unit down to the truck, new unit up to the pad. It has to be lifting the minute it arrives, not waiting on a disconnect that has not happened.

9:00 to 11:00, set and lineset. Installers level the pad, set the unit, braze the lineset, pull a vacuum, and weigh in the charge. Photo the new nameplate and the micron gauge at the target so the readings exist before the gauges come off.

11:00 to 11:30, electrical tie-in. Electrician lands the whip, sets the disconnect, confirms voltage. This is the second time you need the sub, and if he left after the morning disconnect, he has to be back for it.

11:30 to 12:00, startup and sign-off. First cool, temperature split at the registers, condensate line proven to drain. Photo the split reading and the finished install. Then someone with the authority to say the job is done says it.

That is the day. Nothing on that list is a surprise to you. The trouble is never that you do not know the sequence. It is that the sequence lives in one person’s head and the other three are guessing at it from a group text.

What 40 minutes late actually costs

Put the number on it. Say the electrician reads “8am” as “sometime that morning” and rolls in at 8:40.

The crane was booked for a two-hour minimum and arrived at 8:00 on time. For 40 minutes it sits in the street doing nothing, because the installers cannot pull the old unit until the disconnect is done, and the disconnect is the sub who is not there yet. Crane time you are eating: call it $150 to $250 for the idle, depending on your yard. Your two installers stand around on the clock for the same 40 minutes, another 1.3 labor-hours of pure wait.

Then the back half compresses. The braze, the vacuum, the charge: none of that rushes safely, so the whole schedule shifts 40 minutes right. The crew that was supposed to roll to a second call by 1pm now rolls at 1:40, or not at all, and that is a second job that slips to tomorrow. One late player on one changeout is $200 in crane idle, a couple of wasted labor-hours, and a knock-on delay to the next job. Call it $400 to $600 on a bad morning, most of it time you cannot bill.

And the reason is small: the start time never landed anywhere the sub could not misread it. He was not being difficult. He read a text at 6am, half awake, and “8am” competed with four other messages. It did not have a home.

Give the day a place to live

The reminder-text approach fails for the same reason it always fails: a text scrolls away and a start time has to still be true at 6am. What holds a changeout together is two things.

First, the plan lives on the job, not in the thread. The address, the 7:50 call time, the run of show, and the photo you owe at each stage all sit on the job itself, where anyone who opens it sees the same thing. When the sub opens the job the night before, he sees “7:50, disconnect first” and there is nothing to misread. This is the same discipline behind an install checklist that catches the skipped float switch: the day’s steps stop depending on memory.

Second, the photo prompts are baked into the run of show, not left to whoever remembers. Old nameplate before it leaves the pad. New nameplate on the pad. Micron gauge at target. Temperature split at startup. Finished install. Those five shots are the same backbone as the before and after photos that end disputed callbacks, just staged across a changeout instead of a service call. When a customer calls in November saying the unit never cooled right, the split reading from install day is the whole argument, and it only exists if the day told the tech to shoot it. It is also why getting every tech to shoot the nameplate on every call is worth drilling until it is automatic.

Keep a changeout-day sequence taped in every install truck, whatever your crew will actually look at. The point is that the run of show and the photo prompts are the same on every job, so a new installer or a fill-in sub steps into a day that runs the way it always does.

The one player who is not on your roster

The electrician is the piece a group text handles worst, because he is a sub. You do not want to make him buy software for one disconnect and one tie-in, and he would not do it if you asked. But he is the exact player whose late arrival costs you the crane. So he is the one who most needs to see the start time, and the one your usual tools reach the least.

The move is to let him read the same job the rest of the crew reads, without signing up for anything he pays for. He opens the changeout, sees “7:50, disconnect first,” sees the address and the run of show, and confirms he is coming. No forwarded texts, no “did you get my message,” no start time that only lived in your outbox. When the day is over he drops off the job.

That is what Crewmigo is built to do here. Each changeout is its own thread that holds the start time, the run of show, and the photo owed at each stage, so the crane, the installers, and the sub all read the same morning. The nameplate and split shots land on the task they prove, so the record exists before the gauges come off. And your electrician joins as a free guest for that one job: he reads the same start time everyone else does, confirms it, and is gone when the day closes. We are new, so put one changeout on it and watch whether the driveway fills at 7:50 instead of 8:40.
