Breakers that trip every week, lights that dim when the AC kicks on, a fuse box or a Federal Pacific panel in the garage: those are the calls that usually lead to a panel conversation. Number One's licensed Albuquerque electricians have been working on homes across the metro since 2005, and every panel job starts with a load calculation, not a sales pitch. If your existing panel can carry what your home needs, we will tell you so. If it cannot, we handle the upgrade from permit to final inspection.
An electrical panel upgrade replaces the panel that receives power from the utility and distributes it to every circuit in your home, and in many cases it also increases the amperage of the service feeding that panel. The work starts with a load calculation: what your home draws today, what you plan to add, and whether the existing panel and service can carry it. That calculation is what separates a needed upgrade from an upsell, and it is why two homes with the same symptoms can need very different work. Our post on whether your panel is ready for the winter load covers the warning signs that usually start the conversation.
The warning signs we look for are the ones homeowners usually notice first. Breakers that trip regularly, lights that dim when a large appliance starts, a panel that feels warm or shows discoloration around the breakers, buzzing or sizzling from the panel, and no open space for new circuits all point to a panel working at or past its limit. Older equipment is its own category: fuse boxes, split-bus panels, and panels from Federal Pacific and Zinsco, both of which have documented histories of breakers failing to trip when a circuit is overloaded.
Not every problem calls for a new panel. A single overloaded circuit, a loose connection, or one failed breaker can often be corrected on its own, and we will tell you when that is the case. When the panel itself is undersized, damaged, or a known problem brand, a replacement is the safer and more lasting fix.
A home needs a panel upgrade when the load it is asked to carry has outgrown the panel and service it has. The most common trigger today is adding something big: a Level 2 EV charger, a heat pump, refrigerated air in place of a swamp cooler, a hot tub, or an all-electric kitchen remodel. Many homes on 100-amp service need an upgrade, often to 200-amp service, before those loads can run safely alongside everything else. Homeowners planning solar panel installation often find the panel needs attention first.
Inspections are the other common trigger. A home inspection before a sale, or an insurance review, will flag a fuse box or a Federal Pacific, Zinsco, or Pushmatic panel, and some insurers have begun declining coverage until those panels are replaced. A modern panel with open space for new circuits is also a selling point, because buyers want room to add what they need later.
The upgrade itself follows a set sequence. We complete the load calculation, pull the permit, and coordinate with PNM to disconnect and reconnect service. Then we install the new panel with proper grounding and bonding, talk through whole-home surge protection and an outdoor main disconnect for your home, and the work is inspected before it is signed off.
Much of Albuquerque's housing was built in the decades after World War II, and many of those homes still have the electrical service they were built with. That service was sized for a house with a swamp cooler, a gas furnace, a gas range, and a handful of appliances. Homes from that era are also where we find fuse boxes, split-bus panels, and Federal Pacific and Zinsco equipment, along with wiring where one outlet carries the load for several others.
The way Albuquerque homes use power has changed faster than the panels have. Converting from a swamp cooler to refrigerated air adds one of the largest loads in the house, and heat pumps, EV chargers, and home offices add more. Solar adoption across the metro brings the panel into the conversation as well, because a solar system connects to the home at the panel. Each of those projects is a reason to run a load calculation before the work begins.
Monsoon season adds a different kind of stress. Summer lightning and the utility surges that follow storms can damage breakers, appliances, and electronics, and a panel without surge protection gives them no buffer. If a storm has left your panel damaged or your home without power, our emergency electricians answer around the clock at (505) 999-9567.
We evaluate and replace every major residential panel brand, including older Federal Pacific, Zinsco, and Pushmatic panels.
Most panel failures give warning first: a breaker that trips more often, a light that dims, a panel that runs warm. The Uno Care Club is Number One's maintenance membership, with priority scheduling when something goes wrong and repair protection that takes the sting out of an unexpected call. Catching a loose connection or an overloaded circuit early costs far less than replacing a breaker that has melted onto the bus bar.
Members earn up to $600 annually and can bank up to $3,000 in credits.
Real people, real results
"We hired this company to upgrade our electrical panel and put in an AC unit back in May. Everyone is great, very professional. We had a small hiccup and were sure if it was related. It turned out to be a different issue but our house is sort of like a puzzle with all the work it had done from previous owners. Luis answered so quick, scheduled, and kept us informed the whole way. I’m so relieved he found the issue, and fixed it, no problem. We’ll always come to these guys."
"Ricardo was very professional and very helpful. He explained what was going on with my breaker panel and was patient with me trying to understand what happened. He did the repairs quickly. Pricing is very reasonable and fair. Will definitely use them again!"
"We have called upon Number 1 for several issues -- including electrical wiring/panels, water heater maintenance, and furnace repair. They have always provided EXCELLENT and prompt customer service and technical expertise; and their rates are very reasonable. We will continue to call on them for future repairs."
The evaluation and load calculation come first, and we can usually schedule that visit quickly; the upgrade itself is scheduled around the permit and PNM's disconnect and reconnect, and we will give you a realistic timeline once we have seen your panel. If a panel has already failed and left part of your home without power, Number One answers the phone around the clock at (505) 999-9567. Weekend calls are billed at weekday rates; after-hours calls carry an additional charge. Every panel upgrade is backed by our Satisfaction Pledge.
The clearest signs are breakers that trip regularly, lights that dim when a large appliance starts, a panel that feels warm or shows discoloration, buzzing from the panel, and no open space for new circuits. A fuse box, a split-bus panel, or a Federal Pacific, Zinsco, or Pushmatic panel is also a reason to have it evaluated. A load calculation tells you whether the panel can carry what your home draws today.
Not always. A Level 2 charger needs its own dedicated circuit, and whether your panel can carry it depends on the load calculation. Many homes on 100-amp service need an upgrade, often to 200-amp service, to run a charger alongside heating, cooling, and kitchen loads. If your existing panel already has the capacity, we will tell you so.
Yes. Both brands have documented histories of breakers failing to trip when a circuit is overloaded, which removes the panel's main safety function without any visible warning. We recommend an inspection and, in most cases, replacement even if you have not noticed a problem. Pushmatic panels are an outdated design we also recommend replacing.
A panel upgrade includes the load calculation, the permit, coordination with PNM for the disconnect and reconnect, installation of the new panel with proper grounding and bonding, and the final inspection. We will also talk through whole-home surge protection and an outdoor main disconnect for your service.
No. A breaker is sized to protect the wire behind it, not the appliance plugged into it. A larger breaker lets that wire carry more current than it was designed for, which is how wiring overheats inside walls. A breaker that trips repeatedly is telling you the circuit or the panel is overloaded, and that needs a diagnosis rather than a bigger breaker.
Weekend calls are billed at weekday rates; after-hours calls carry an additional charge. Planned panel upgrades are scheduled during regular hours, and we answer the phone around the clock if a failing panel has left you without power.
