A man calls a residential electrician on the Saturday after a three-day outage. His street went dark Wednesday evening and the power came back Friday night. He lost a freezer full of food, his sump pump sat idle through eleven hours of rain, and his neighbor two doors down never flickered. He has decided he is buying a standby generator and he wants to know what it costs.
The office takes his name, his number, and a note that says "wants whole house generator," and books a Tuesday estimate. Tuesday, a tech drives thirty-five minutes out, walks the property, and finds no natural gas at the street. The propane conversation the homeowner has never had starts in his driveway. The panel is a 100 amp split-bus with no main breaker. The only viable generator pad location sits four feet from a bedroom window, and the township has a setback ordinance the tech will have to go look up. The visit turns into a fact-finding trip, no number gets quoted, and the homeowner spends that evening calling the two other electricians whose voicemail he left a message on Saturday.
None of that was unknowable on the phone. Every one of those facts was a question somebody could have asked before a truck moved. Standby generator work is one of the highest-ticket residential jobs an electrical contractor sells, and it is also one of the most dependent on site conditions that a homeowner can describe accurately if you ask them plainly. The consultation call is where the job gets scoped or where it gets lost.
Why generator calls need real intake
A generator inquiry is not a service call and it should not be handled like one. Three separate trades and at least two outside parties can touch the finished job. There is the electrical side, the fuel side, the permitting and inspection process, and often a utility or propane supplier with their own calendar. A generator sale also arrives with a long equipment lead time attached, which means the timeline you set on the first call is the expectation you live with for months.
The callers themselves are also not all the same job. Some want a whole-home system and have the budget for it. Some want the furnace, the fridge, and the well pump covered and would be happier with a managed load setup. Some are describing a portable generator and an inlet box without knowing that is what they mean. A few are calling every listing in the county to collect three numbers and will book with whoever sounds like they have done this before.
You cannot sort those apart from "how much for a generator." Intake is how you decide which caller gets a same-week visit, which one needs a load conversation before anyone drives out, and which one you can scope well enough over the phone to arrive with a proposal instead of a clipboard.
Fuel source: ask before anything else
Fuel is the question that reshapes the entire job, and it is the one most likely to be assumed rather than confirmed.
Does the home have natural gas service today? Not "is there gas in the area." Ask whether they currently have a gas appliance running, a furnace, a water heater, a range, a dryer. A homeowner who heats with oil and cooks on electric usually has no gas service at all, regardless of what the neighbors have.
If there is gas, what else is on the meter? Furnace, water heater, range, dryer, fireplace, pool heater. A generator is a substantial addition to a residential gas load, and whether the existing meter and line can carry it is a question for the utility or the gas fitter, not something to promise on the phone. What you want from the call is the appliance list and the approximate distance from the meter to the proposed generator location, so the person who has to answer that question has something to work with.
If there is no gas, is there already a propane tank? Ask whether it is owned or leased, what size, and who supplies it. A leased tank from a supplier with a contract is a different conversation than an owned tank. If there is no tank at all, the homeowner is buying or leasing one, finding a place to put it, and adding a supplier relationship to the project. Many callers have not thought about that yet, and hearing it from you first is better than hearing it from a competitor.
Have they thought about how long they want to run? Propane runs out. Natural gas generally does not. A homeowner in an area where outages last days should hear the tank sizing conversation early rather than after the install.
Write the fuel answers into the lead. A generator lead that says "natural gas, furnace plus water heater plus range on the meter, meter on the east wall, pad location roughly forty feet away" is a job you can start engineering. A lead that says "wants generator" is a truck roll.
Load: what are they actually trying to keep on
The sizing conversation is where homeowners anchor hardest on a number they read somewhere, and where the first call earns the most trust by slowing them down.
The useful question is not what size generator they want. It is what they want to still be working when the power goes out. Walk them through it.
Whole house or essential circuits? A whole-home system carries the entire panel and nothing in the house notices the outage. A managed or essential-circuits setup covers a defined list. Both are legitimate and the choice drives the budget more than any other single decision.
What is the heating and cooling equipment? Gas furnace with a blower is a modest load. Electric furnace or heat strips is an entirely different number. Ask how many air conditioning or heat pump condensers are outside and whether they know the tonnage or can read the model number off the label.
Is there a well pump, a septic pump, or a sump pump? These matter far past their nameplate rating because motor loads draw a large surge on startup. A rural property on a well and a septic lift station has a load profile the caller will never think to mention unprompted.
What is the range, the dryer, and the water heater? Gas or electric on each. Three electric appliances change the answer.
Anything unusual? Home office, medical equipment, an EV charger, a workshop, a pool, a hot tub, a second refrigerator or freezer in the garage. The freezer is often the reason they are calling in the first place.
What is the existing service size and panel? Main breaker amperage, panel brand, and whether there are open spaces. If the panel has no main breaker at all, that is a split-bus configuration and needs eyes on it. If the brand is one of the obsolete lines, the generator job may be sitting on top of a panel replacement, and you want to know that before you quote.
None of this is a load calculation. It is the input list for one. Gathering it on the phone is what lets the site visit confirm and price rather than discover.
Transfer switch: capture the configuration, not a code lecture
Most homeowners have never heard the term, and the phone is a good place to explain it in one sentence: the transfer switch decides whether the house is being fed by the utility or by the generator, and it makes certain the two are never tied together at once. That isolation is the entire safety premise, because power pushed back onto a line that the utility believes is dead puts the crews restoring service at risk.
What the call needs to capture is the configuration, not a code opinion. The specifics of what is required for a given install belong to the AHJ and the manufacturer's instructions, and those vary by jurisdiction. Ask the questions and let the design answer them.
Automatic or manual? Most standby buyers want automatic, because the appeal of the system is that it works when nobody is home. It is worth confirming rather than assuming, since a manual switch is a meaningfully different price.
Whole panel or a subpanel of selected circuits? This follows directly from the load conversation and determines the switch rating and where it lands.
Where is the existing panel and meter, and are they together? Interior basement panel with an exterior meter, an outdoor meter-main combination, a garage wall, a finished hallway closet. The distance and the path between the meter, the panel, the switch, and the generator pad is most of the labor.
Is there anything already installed? Some homes have an inlet box and an interlock kit from a previous portable setup. Some have an old transfer switch from a generator that was removed. Occasionally a homeowner describes a suicide cord arrangement, and that is a conversation to have carefully and immediately.

Permits, siting, and the questions intake should flag
Generator installs generally involve permitting and inspection, and often more than one permit, because the electrical work and the fuel connection are separate scopes. What applies specifically is a local question. The job of intake is not to answer it on the phone but to collect the facts that determine the answer and flag them for whoever pulls the permit.
What is the exact address and jurisdiction? Township, borough, city, and county all matter, and the caller's mailing address does not always match the authority that issues the permit.
Is the property in an HOA, a historic district, or a flood zone? Any of the three can add an approval step or restrict placement.
Where do they want the unit, and what is around that spot? Distance to the nearest window, door, and property line. What is on the other side of the wall. Whether there is a deck, a patio, a heat pump, a meter, or a dryer vent nearby. Setback and clearance rules vary by jurisdiction and by manufacturer, and noise ordinances exist in plenty of towns. You are not adjudicating any of that on the call. You are writing down the geometry so the person who does has it.
Is there a slab or pad already, and what is the ground like? Grade, drainage, and whether the spot is reachable by equipment.
Is the caller the owner? A tenant cannot authorize this work, and on a shared-wall property there may be a second party.
Lead time: set the real expectation on the first call
This is where a lot of generator jobs quietly go sideways. The install itself is often a short piece of the calendar. The project is long, because it includes the load calculation, the equipment order, the fuel work, the permit, the inspection, and any utility or propane supplier scheduling. Equipment availability moves with the season and tightens after any large regional outage, which is exactly when your phone is ringing.
The homeowner who called on Saturday after a three-day outage wants it done before the next storm. Telling him plainly on the first call that this is a project measured in weeks, with the specific holdups named, is not a way to lose the sale. It is the thing that keeps him from booking a competitor who promised faster and then missed. Ask what is driving his timeline too, since a closing date, a medical need, or a planned surgery changes how you sequence him.
The generator call you did not answer
Everything above assumes somebody picked up.
Generator demand is weather-driven and it arrives in clusters. The regional outage that convinces two hundred homeowners to finally buy a standby unit is the same event that has your entire crew in the field restoring service, chasing dead circuits, and handling genuine emergencies. Nobody is at a desk during the exact window when the highest-value leads of the quarter are dialing.
Those callers are motivated and impatient, and they are working down a list. The pattern across the service trades is unforgiving: a call that reaches voicemail frequently becomes a call to the next contractor, with no message left behind. The jobs lost this way are the ones that sting, because the homeowner had already decided to spend the money and had already chosen to dial you.
Coverage is the fix, and there is more than one way to get it. Front-desk staff can run the intake and book the load-calc visit. An answering service can catch overflow. An AI receptionist for electrical contractors can answer during the storm-week rush, ask the fuel, load, panel, and siting questions in the order you would ask them, and put a consultation on the calendar with those answers attached. What matters is that the caller reaches a real intake instead of a voicemail box, and that the notes are in front of your estimator before the callback. You can see how the call handling side works here.
What a good generator lead looks like
By the end of the call you want a record that lets someone either price the job or arrive prepared to:
- Fuel source, existing gas appliances on the meter, or propane tank status and supplier
- Whole-home or essential circuits, and the circuit wish list if it is the latter
- Heating and cooling equipment, water heater, range, and dryer, gas or electric on each
- Well, septic, or sump pumps
- Service size, panel brand, panel location, and open breaker spaces
- Meter location and distance to the proposed generator pad
- Proposed unit location with distances to windows, doors, and the property line
- Address, jurisdiction, HOA or historic district status
- Owner or tenant, and what is driving the timeline
- Any existing inlet, interlock, or transfer equipment
That is a job sheet. The alternative is a name, a number, and "wants generator," which is the version that sent a truck thirty-five minutes out to learn there was no gas at the street.
FAQ
What is the single most important question on a generator consultation call? Fuel source, confirmed rather than assumed. Ask whether the home currently runs any gas appliance, and if not, whether there is an existing propane tank. Nearly every other part of the scope, the timeline, and the outside parties involved follows from that answer.
How much load detail should we gather on the phone? Enough to feed a load calculation, not to perform one. Heating and cooling equipment, water heater, range and dryer fuel type, any well or sump pumps, and the existing service size will get you most of the way. Motor loads matter more than homeowners expect because of startup surge, so ask about pumps and condensers specifically.
Should intake tell the customer what the permit requirements are? No. Permitting, setbacks, clearances, and noise rules vary by jurisdiction and by manufacturer instructions. Intake should capture the address, the jurisdiction, the HOA status, and the proposed location with distances to windows, doors, and the property line, then flag it for whoever pulls the permit.
Why do generator leads get lost more often than other electrical work? The demand is driven by outages, and an outage puts the whole crew in the field on the same day the calls come in. The caller has usually already decided to buy and is phoning several contractors in a short window, so an unanswered call tends to become someone else's job rather than a callback.
