"Jason and his team upgraded and replaced the electrical panels, meter sockets, and most of the outlets at a multi-family property I own. They did incredible, clean, safe work. And even communicated with the tenants! They made everything easy, and the inspection passed with flying colors. Incredible job!"

"GREAT! Joe was easy to work with, very skilled and knowledgeable, and very reasonable. The work he did was top notch (fast, he cleaned up, wore a mask, etc) and he even spotted some extra work that needed to be done for safety reasons (fixing a wire outside the house). We've hired him before and absolutely will again for anything electrical."

"The electricians from Wired were excellent. I needed some immediate work on a wonky outage. It was found, repaired and took more than a little detective work to find. I asked for a quote on various other work, new outlets, moving service location ets. The prices were fair, work scheduled promptly and done as quoted. I would recommend Wired for all your needs. And they have great trucks.......!"

"We had a list of items that needed to be completed (driveways lamps posts/lighting, cathedral ceiling fan, various fixtures, etc.) and a couple of more involved projects we were thinking of doing, like a hot tub installation. Harland Electric was responsive, prompt, courteous and professional throughout the entire process—from initial contact, estimate and work. They itemized each of the projects so that we could pick and choose the work that needed to be done, and were helpful in detailing the complexities of certain projects and weighing the pros and cons of having electrical work done. During the course of coming to the house and knocking every item off of our list (which took 1.2 days worth of work/time), they also alerted us to an electrical fire hazard for an outdoor flood light that another electrician from another previous company just left and said was okay. They replaced the entire light and wiring and now it looks great the way it illuminates our side yard! We even overpaid at the end of the project and they immediately let us know! They are scheduled to return in the spring to install a pool heater and we have no doubt they will do a great job. Overall, great service, highly ethical company and good value overall. Highly recommend!"

"These guys always do a great job.  Pete, the owner, stays on top of everything, and he has a knack for hiring people who do good work.  There are also always professional, friendly and easy to work with. <br /> On more than one occasion, they have gone above and beyond to help me out and make sure things are right.  In one case, the general contractor for a project we were working on disappeared and Pete was instrumental in helping me clear some of the city inspections (like the smoke detectors) that the GC left hanging. <br /> I know that sometimes people have trouble reaching Pete, and I know why.  I have personally never had that happen, so I gave them an A on responsiveness based on my own experience, but if you do have trouble getting ahold of them and you can afford to wait a week or two and try again, your patience will be rewarded. <br /> The prices charged are reasonable: fair, but not low.  If you're determined to find the cheapest electricians in the area, I'm sure Angie's List can help with that but you're on the wrong page at the moment.  Since bad wiring can burn down my house with me inside, I'd rather skip the cheapest and get the best guys I can find.  These are them. <br />"

FAQs for electrical wiring or panel upgrade projects in Concord, MA

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
