A charger simply works, so you never hear from the customer again.
EV charger play · Past customers
Past EV charger customers need more than you think: second cars, new connectors, smarter chargers.
A charger installed three years ago may no longer fit the household. They might have a second EV, a car with a different connector, a new utility rate, or a heat pump on the way. Spur mails your list about their own install, so the next job comes to you.

The problem
Charger customers disappear after the inspection passes.
A new car comes along, the owner searches online, and a new installer gets the call.
Owners who liked your work can't remember your name when a neighbor asks.

AI draft for Neil F. · 3640 Evergreen St
Hi Neil,
We installed your home charger in 2022. A lot has changed for EV owners since then. Many new cars have a different plug, some households have added a second EV, and utility rates have changed in ways that can make scheduling worthwhile.
We'd be glad to review your setup at no charge. We'll check the install, see how it fits your cars and your rate plan, and tell you plainly if something's worth changing. Most of the time, it's a quick conversation.
Scan the code on this card to set a time. And if a neighbor ever asks, we'd be happy to help them too.

What your past EV charger customers need now
A charger install feels like a one-time job, because the equipment simply works once it's in. But the world around it keeps changing. EV households change cars and add cars, utilities change their rates, and new loads like heat pumps change what the panel has to do. A customer you served three years ago likely has at least one reason to talk with you, and they would rather talk with someone they already know.
Second EVs are the obvious opening. Your earlier install tells you the panel size, the circuit, and the garage layout, so you can quote quickly and accurately. Sharing power between two chargers may be easy or may take some changes, depending on the equipment. You're in the best possible position to explain that, and the customer already has a reason to trust your opinion.
Connector changes are a newer issue. Many new EVs ship with NACS (J3400) ports, while many home chargers have J1772 plugs. Adapters may solve it, and some chargers offer a cable swap, so check the vehicle and charger makers' guidance rather than assuming. Mention it as a question: 'New car with a different plug?' Owners who have just run into this issue will recognize themselves right away.
Older plug-in installs may deserve a second look. Some early home setups used a NEMA 14-50 outlet with a portable cord. In recent code editions, 240-volt garage receptacles generally require GFCI protection, which can cause nuisance tripping with some EV equipment, and that's a common reason owners move to a hardwired unit. Check your local adopted code and what's installed before recommending anything, and only recommend changes that have a real benefit.
Rates and other loads are a further reason to reconnect. Many utilities offer time-of-use or EV-specific rates, and a smart charger or the car's own scheduler can make use of them. A heat pump or induction range in the household's plans may change the panel math, and a quick load review gets you involved early. Don't promise savings on rates, which vary by utility, and which can change.
Clean your list, and make it routine. Homes that have been sold should get a separate note, since the new owner may inherit a charger and have no idea how it was installed or what's on the circuit. Mail about two years after each install, then once a year. Add a referral line each time. Your earlier work is your strongest marketing, as long as your customers can still find your number.

FAQ
Past customer questions
Why would a past EV charger customer need anything?
A second EV, a new car with a different connector, a new utility rate, or a new load like a heat pump can all change what the household needs.
What's a good offer for past customers?
A free review of the setup, with a plain answer on whether anything's worth changing. Most of the value is in starting the conversation.
Should I recommend moving from an outlet to a hardwired unit?
Only when it has a real benefit. Recent code editions generally require GFCI protection on garage receptacles, which can cause nuisance tripping. Check your local code and the equipment first.
What about homes that have been sold?
Send the new owner a separate note. They may have inherited a charger, and they may not know how it was installed or what's on the circuit.
How do I get my list into Spur?
Upload a CSV from your job software or a spreadsheet, including the install date and charger details if you have them.
