Panel & Service Upgrades in Glendale Heights

Many Glendale Heights homes still have the 100-amp panel they were built with. That was plenty for a 1970s household, but central air, electric dryers, remodeled kitchens and EV chargers all compete for the same capacity today. When the panel runs out of room or breakers start tripping under normal use, Electrician's Precision Pros calculates your actual load and upgrades service across Glendale Heights, Bloomingdale, Carol Stream and Addison so the house has headroom for years to come.

What the upgrade involves

Typically a new 200-amp panel and, where required, a new meter socket, service entrance conductors and grounding. We start with a load calculation so the new service is sized for what you run now and what you plan to add. We pull the permit, coordinate the disconnect and reconnect with the utility, and schedule the village inspection. Power is off for part of one day, and we tell you how long in advance.

Planning for an EV or remodel

If an EV charger, kitchen remodel or basement finish is on the horizon, it's worth sizing the panel for it now. We map out the circuits you'll need, leave spaces for them, and can rough in conduit for a future charger so the later job is quick and tidy.

Panel Upgrades questions

How long does a panel upgrade take?

Most are completed in a single working day with power off for part of it. We give you the schedule after the assessment.

Is a permit required in Glendale Heights?

Yes. Panel and service upgrades require a permit and inspection. We handle both.

Will the utility be involved?

For a service upgrade, yes. They disconnect and reconnect power at the meter, and we coordinate the timing.

Can a subpanel solve my problem instead?

If your service is large enough but the panel is out of spaces, a subpanel can be a good fit. We'll tell you which approach makes sense.
