Everything you own draws power now, and houses built a few decades back were never asked to supply this much of it. The lights dip when the air conditioning starts. Two appliances running together is enough to take a circuit down. An electrician tells you the charger you want isn't going in without changes to the service first, and suddenly a simple project has grown considerably. Advanced Electrical Repair handles 200-amp electrical service upgrades for homeowners throughout Milliken, CO, and the surrounding communities, taking a home from a service that's maxed out to one with genuine headroom.
Advanced Electrical Repair works as a veteran-owned electrical contractor out of Milliken, Colorado, taking jobs in the communities running up and down the corridor north of Denver. Ben DeVries started the company in 2015 after roughly fifteen years already spent in the trade, and service upgrade work has become one of its specialties: load calculations, new service entrance conductors, meter socket replacement, main panel installation, grounding electrode systems, and the utility coordination holding all of it together. Older houses are where most of these projects happen, since their original service reflects mid-century expectations rather than the way anybody lives today. Nothing gets energized until it's permitted, coordinated with the power company, and inspected.
Homeowners rarely call about their service directly. They call because a contractor told them the basement plan requires more capacity, or because a hot tub quote came back with an unexpected line item, or because lights across the house dim noticeably every time something large kicks on. That dimming is the clearest signal, since it means the service is sagging under demand it can't comfortably meet.
The arithmetic behind it is simple enough. A 100-amp service delivers roughly 24,000 watts at 240 volts, and that number sounded generous when houses had one television, a gas range, and no central air. Add an electric dryer, a modern kitchen, central cooling, a well pump or sump, a shop in the garage, and a car that wants 48 amps overnight, and the calculation stops working. Older services also frequently arrive on undersized conductors with a grounding system that predates current requirements, so the wire and the electrode both need attention alongside the panel. Squeezing more circuits into a full enclosure doesn't address any of it, because the constraint sits at the point where power enters the house.
Our process opens with a formal load calculation covering your existing appliances, square footage, heating and cooling equipment, and anything you're planning to add. That number determines whether 200 amps is the right target or whether your household would be better served at a different size. From there we contact the utility to arrange the disconnect and any changes on their side, pull the permit, and set a date. The work itself includes new service entrance conductors, a new meter socket in most cases, a 200-amp main panel, an updated grounding electrode system, and the transfer of every branch circuit onto correctly rated breakers with arc-fault and ground-fault protection where required. The inspection follows, then the utility reconnects and energizes.
What changes afterward is the feeling that your house is holding something back. Lights hold steady when the compressor starts. Multiple heavy loads run at once without drama. A charger, a hot tub, a shop subpanel, or a finished basement becomes a normal project rather than an obstacle, and you're not paying to open the service back up two years from now because a second upgrade turned out to be necessary.
Capacity is one of those improvements you feel constantly without ever pointing at it directly.
Charger installations, hot tubs, shop subpanels, and finished basements all hinge on available capacity, and a maxed-out service turns each one into a two-part job. Doing the upgrade first means those projects proceed on their own terms. Homeowners planning more than one improvement save real money by sequencing it this way.
Lights that dim when the air conditioner or well pump starts indicate a service working harder than it should. More capacity holds voltage where it belongs across the whole house. Motors and electronics both last longer on a stable supply.
Grounding requirements have changed substantially since older services were installed, and upgrades bring the electrode system up to current standards. This is the piece nobody sees and everything depends on. Surge protection also becomes a practical option once the grounding is sound.
Conductors, meter sockets, and weatherheads deteriorate outdoors over the decades, and damage there tends to go unnoticed until it causes trouble. An upgrade replaces those components with new materials rated for the load. Everything from the drop to the panel ends up documented and inspected.
Buyers and their inspectors ask about service size, and a documented 200-amp service answers a question that would otherwise become a negotiating point. Appraisers in this market notice it as well. Permitted work with an inspection record is what makes that claim credible.
Raising the service usually touches other parts of the system, and these are the services that come up alongside it most often.
Increasing amperage nearly always means a new enclosure as well, which is why electrical panel replacement typically happens in the same project. Combining the two avoids paying twice for overlapping labor and permits.
Homes that already have adequate service sometimes need nothing more than attention at the breaker level, making circuit breaker replacement the practical alternative. Correctly listed components restore protection without the expense of touching the service entrance.
Everything described here falls within our larger electrical panel upgrades practice, which also covers code-compliance corrections and home electrical inspections. An inspection early on is usually the fastest way to learn whether your service is genuinely the limiting factor.
Work at the service entrance involves the utility, the building department, and the safety of everything downstream, so experience carries weight here.
Sizing a service properly means running numbers on your actual home instead of defaulting to whatever's common, and that calculation sometimes shows an upgrade isn't warranted at all. The Independent Electrical Contractors Rocky Mountain (IECRM) supplies the continuing education that keeps our load calculation methods aligned with what's currently required.
Service changes require scheduling a disconnect and reconnect with the power company, and that coordination trips up plenty of projects. Handling it is part of what we do rather than something we hand back to the homeowner. Timelines get communicated as we learn them.
Homes throughout Milliken, Platteville, Johnstown, and the older parts of Longmont share a set of predictable conditions at the service, and knowing what's likely behind the meter shortens the surprises. That experience shows up in estimates that hold.
Estimates are free and detailed enough that you understand what's driving the number. Service upgrades represent a significant investment, so financing through Joist is available, and we'll walk you through applying while we're out.
Being a veteran-owned business rooted in Milliken means we run into our customers around town, which sharpens the incentive to do things properly. Our labor comes with a twelve-month guarantee, while installed equipment falls under the warranty its maker provides.
Lights dimming under load, a full panel, and plans involving a charger, hot tub, or finished basement are the usual indicators. The definitive answer comes from a load calculation on your specific home rather than a rule of thumb. We run that during the free estimate so you're deciding with real numbers.
Yes, since raising the service means disconnecting and reconnecting at the meter, which only the utility can perform. We arrange that scheduling as part of the project. Utility lead times occasionally influence the timeline more than the electrical work itself does.
Most upgrades in Milliken and the neighboring towns keep power off for the better part of a working day. Weather, utility availability, and inspection scheduling can extend that. Planning around refrigeration and any medical equipment ahead of time is worth doing.
Not always, and plenty of homes accommodate a charger on existing service once the load calculation confirms the room is there. Houses already near capacity generally do need the upgrade first, or a load management device as an alternative. We assess this before anyone orders equipment.
Permitting and inspection are required across the jurisdictions we serve, including Milliken, Johnstown, Mead, and unincorporated Weld County, with specifics varying by location. We handle the permit and the inspection ourselves. The resulting documentation matters later for insurance and resale.
