A heavy-up is an increase in the size of your home's electrical service, usually from 100 or 150 amps up to 200 amps. Many homes in Alexandria, Springfield, and Annandale were built when a house's biggest electrical loads were a range and a window unit. Today, a heat pump, an EV charger, and a modern kitchen can easily push past what the original service was designed for.
Warning signs include breakers that trip when two large appliances run at once, lights that dim when the AC kicks on, a panel with no open slots, or an older panel brand known for problems. If you're planning a remodel, an addition, or new HVAC equipment, it's worth having the load checked before the work starts.
A heavy-up involves a load calculation, a permit, a new panel or meter base as needed, and coordination with the utility to upgrade the service drop. A licensed electrician handles the work, the inspection confirms it, and the utility reconnects power, usually within a day.
Because Greenpoint Services is licensed in electrical, HVAC, and plumbing, we can plan a heavy-up together with the equipment that needs it, so you aren't waiting on one contractor to finish before the next can start.
