EV Charger Replacement & Circuit Upgrades
Swapping out a failed or outdated charger, upsizing an undersized circuit, and reworking installs that were never done right.
Chargers age faster than panels do
Early Level 2 chargers are now a decade old. Contactors wear, connectors get brittle in Colorado winters, app support gets discontinued and charging speeds that felt generous in 2015 feel slow next to a modern 250-mile battery.
Replacing the unit is straightforward when the circuit behind it is sound. We verify the circuit, conductors and breaker before we mount anything new, because a new charger on a tired circuit just moves the problem.
When the circuit needs upgrading too
A lot of first-generation installs landed on a 30-amp circuit. If your new vehicle can accept 48 amps, keeping the old circuit means paying for a charger you cannot fully use.
We evaluate whether the existing conductors, breaker and panel capacity support the higher amperage, then either upsize the circuit or explain honestly why the panel needs attention first.
- Conductor and breaker sizing verified against the new charger
- Panel capacity re-checked with a fresh load calculation
- Old receptacle replaced when it shows heat damage
- Load management added when capacity is tight
Fixing installs that were never right
We see extension-cord workarounds, undersized wire, missing GFCI protection, unpermitted work and receptacles melted from a loose connection. None of that is worth living with in an attached garage.
If we find an unsafe condition, we photograph it, explain it and quote the correction. Then we pull a permit and leave it documented and inspected.
Our process
How an EPO replacements job runs
- 01
Assessment
We inspect the existing charger, receptacle, breaker and conductors, and test what the circuit is actually delivering.
- 02
Recommendation
Straight swap, circuit upgrade or panel work first — with the reasoning and the price for each.
- 03
Scheduling and permit
Permit pulled when the circuit is being modified; scheduled around your charging needs.
- 04
Replacement
Old unit removed, new charger mounted and terminated, circuit tested under load with your vehicle.
- 05
Verification
We confirm charge rate at the vehicle and close out the inspection.
Pricing
What moves the price on this job
We quote after seeing the equipment, because these details change the number more than anything else.
- Straight swap versus circuit upgrade
- Conductor size already in place
- Charger relocation distance
- Damage to the existing receptacle or breaker
- Whether panel capacity work is required
Monthly payments available through Hearth
Prequalifying takes about a minute and uses a soft credit check, so seeing your options does not affect your credit score.
FAQ
Common questions
Can you reuse my existing circuit?
Often yes, if the conductors and breaker match the new charger's requirements. We verify rather than assume.
My charger's outlet is discolored. Is that serious?
Discoloration usually means heat from a loose or undersized connection, and it should be looked at promptly. Stop using the outlet and call us.
Can you move my charger to a different wall?
Yes. We can extend or reroute the circuit, or add a subpanel if the new location is far from the existing one.
Do you work on chargers you didn't install?
Yes. A large share of our EV work is correcting or upgrading someone else's installation.
Why does my EV charger keep tripping the breaker?
Common causes are an undersized or overheating breaker, a loose termination, a shared circuit or a failing charger. We test the circuit under load rather than swapping parts and hoping.
Should I replace a plug-in charger with a hardwired one?
Hardwiring removes the outlet, which is the part that most often overheats on a 40 amp continuous load. If your receptacle is discolored or your charger supports it, hardwiring is the more durable setup.
Can you upgrade a 32 amp charger circuit to 48 amps?
Only if the conductors and panel capacity support it. We check wire size, breaker space and the load calculation, then tell you whether it is a breaker change or a full circuit rerun.
How long does a charger replacement take?
Usually two to four hours when the existing circuit is sound. Rerouting or upsizing the circuit adds time, and we tell you which one you are looking at before we start.
Do you need a permit to replace an existing EV charger?
Replacing equipment on an existing, correctly sized circuit often does not, but any new or modified circuit does. We confirm with your jurisdiction rather than guessing.
