How to Walk a Customer Through an Electrification Plan

Why this matters

Most houses do not convert in one project. They convert one failure at a time: the water heater goes in year two, the AC dies in a heat wave in year four, the range gets swapped when the kitchen is redone. A shop that only quotes the appliance in front of it installs each piece without regard to the next, and the third piece is the one that needs a service upgrade the first two could have avoided, or lands on a gas water heater now venting alone into a chimney sized for a furnace.

A written phased plan fixes that. It tells the customer what happens now, what happens when each appliance fails, and what can wait, so every emergency call already has a decision behind it. It also gives your shop the next three jobs at that address, earned honestly rather than pushed. This article covers building the plan from the site survey and presenting it so the customer owns the timing. The order of a whole-house conversion is owned by the sequence card and the load measurement by its own card; this one turns their outputs into a page the customer can keep.

Step 1: Start from the survey record, not from the conversation

Build the plan at the desk from what the survey recorded, then talk to the customer. Writing it on the spot, standing in the kitchen, produces a plan shaped by whichever appliance the customer complained about, and it skips the capacity arithmetic because nobody does arithmetic in a kitchen.

The inputs you need, all of which the survey procedure collects: every fuel-burning appliance with its age, fuel, input rating and venting; the service rating and panel space; a measured peak demand, or a note that you have not measured yet; duct condition; envelope notes; and what the customer said about money, comfort and how long they plan to stay. If the measurement is missing, the plan says so, and its first "now" item is to measure. See related: The Electrification Site Survey SOP.

What breaks if you skip it: the plan silently assumes capacity it has not checked, and the shop discovers the constraint on the third install.

Step 2: Put every appliance on its own line with its trigger

Give every gas or propane appliance a line, including the ones the customer does not want to change. Then assign each to one of three phases by the event that should trigger it, not by a date:

• Now: work that pays whether or not anything fails, or that makes later steps cheaper (air sealing, insulation, a measurement, a circuit pulled while the wall is already open).
• At failure: the appliance stays until it dies or becomes unsafe, and the plan records exactly what replaces it so nobody improvises on an emergency call.
• Later: things that depend on the others being done first (closing out gas service, a car charger, solar).

Ages drive the "at failure" order. A water heater at 9 years and a furnace at 19 are both at-failure items, but the furnace is likelier to go first, so its line gets the more detailed replacement spec.

Step 3: Run the capacity line against the phases in order

Add each phase's new load to the measured headroom in the order the plan expects them to arrive, and mark the phase where the headroom runs out. That phase is where the service question lives, and it is usually not the first. Do the load method once, by the rules in the measurement card; here you only need its output, the remaining amperes, and the nameplate figures of what you plan to add. See related: Measuring Existing Load Before You Sell a Service Upgrade.

The point of running it in order is that it moves the service decision to the right moment. A customer told "you need a bigger service" on day one hears a large bill for a problem they do not have yet. A customer shown "phases one and two fit; the range and dryer are where it gets tight, and here are the ways around that" is looking at a choice they can make in three years with better information. See related: Alternatives to a Service Upgrade.

Step 4: Mark the dependencies between lines

Some lines change others. Removing the furnace can leave the water heater as the only appliance on a flue sized for both, which is a venting problem the moment the furnace leaves, not a later item. Closing out gas service cannot happen while any gas appliance remains, and keeping one gas appliance has its own cost. Write each dependency as a short note on the line it affects, so the tech who arrives for the furnace replacement sees "water heater orphaned on this flue, venting check required" without having to know the history. See related: What Removing a Gas Appliance Does to the Ones Left.

Step 5: Keep it to one page, in plain words

The plan the customer keeps is one page: their house, three phases, each line with a replacement and a trigger, the capacity note, and the dependencies. No equipment model numbers, no price, no incentive figures. Prices go on quotes when a phase is triggered; incentives change faster than appliances fail, and a plan that leans on one ages badly. See related: Federal Incentives: What Ended and What Is Durable.

Here is the page for the house in the example below:

ELECTRIFICATION PLAN - 1962 ranch, 1,450 sq ft
Service 100 A, measured peak 46 A (30-day log)
Headroom after 1.25 factor: 42.5 A

NOW
 - Air seal attic, insulate to survey target
 - Pull 240 V circuit to WH closet (wall open)
AT FAILURE
 - Water heater (gas, 9 yr) -> heat pump WH
     est. 3 A on the capacity line
 - Furnace (gas, 19 yr) + AC (13 yr) -> heat
     pump, 18 A; strips limited, see note
     NOTE: WH alone on old flue if furnace
     goes before WH. Venting check that day.
 - If AC fails first: heat pump now, keep
     furnace as backup until it fails
LATER
 - Range (gas, 6 yr) -> induction, 32 A
 - Dryer (gas, 15 yr) -> heat pump dryer, 12 A
     CAPACITY RUNS OUT HERE. Options at the
     time: load sharing, smaller range, service
 - Close out gas service after last appliance

Step 6: Present it at the table, then leave it

Sit down with the page, not a screen. Walk it top to bottom once, then stop and ask which line worries them most. Customers rarely care about the order you care about; they care about the appliance they distrust. Answer that line in detail and leave the rest on the page.

Three things keep the conversation free of pressure, and customers can tell the difference:

• Say what is urgent and what is not. On most plans, nothing is. If something is (a failed venting test, a cracked heat exchanger), that line gets its own conversation that day and is not part of the plan.
• Give them the page. Leave it, and file a copy in their customer record. A plan they cannot take away reads as a pitch.
• Ask for one decision only: permission to do the "now" items, or permission to call when a trigger arrives. Nothing else today.

Worked example: the ranch with 100 amps

The survey recorded the figures on the page above. The 30-day log showed a peak of 46 A. Applying the 1.25 factor the load method calls for (NEC 220.87 as adopted): 46 times 1.25 is 57.5 A, and 100 minus 57.5 leaves 42.5 A of headroom.

Running the lines in expected order, with illustrative nameplate-based figures: the heat pump water heater adds about 3 A, leaving 39.5. The heat pump adds 18 A, leaving 21.5. The customer's first instinct was 5 kW of strip backup, which at 240 V is about 21 A; 21.5 minus 21 leaves half an ampere. That fits on paper by half an amp, which is not a pass. It is a reason to size the backup down, use the outdoor lockout, or pair the strips with load management, and the plan says "strips limited" for that reason.

The range at 32 A and the dryer at 12 A together want 44 A against whatever is left. Even with no strips at all, 21.5 A remains before the range, and 44 A does not fit in 21.5. So the plan marks the later phase as the capacity limit and lists the options to weigh then, rather than selling a service upgrade now for loads that may be three or more years out.

The customer's worry was the furnace, because a neighbor's had failed in January. The tech walked that line: what replaces it, what happens if the AC goes first, and the water heater venting note. The customer approved the attic work and asked to be called if the furnace showed trouble. Four months later the water heater leaked; the dispatcher opened the plan, saw the heat pump water heater line and the prepared circuit, and quoted it the same day.

What changes the answer: a customer selling within two years usually wants only the "now" items that show up in an appraisal or an inspection, and the at-failure lines become a note for the buyer. A house with a measured peak much closer to the service rating moves the capacity limit to the first heat pump line, and then the service conversation genuinely belongs at the start.

How to know the plan is doing its job

Three checks, each run when a trigger arrives. First, the dispatcher or tech answering the emergency call can find the plan in the customer record and quote the replacement it named without starting from scratch. Second, the capacity line was updated after each install with the new measured or calculated headroom, not left at its original figure; a plan whose capacity figure never moves is already wrong after the first phase. Third, the dependency note fired: the tech replacing the furnace ran the venting check on the water heater. If any of the three fails, the plan existed only as a sales document.
