- Know the Signs
When Does a Business Need a Commercial Electrician?
Don’t wait for a shutdown. Call a licensed commercial electrician if you:
- Have breakers that trip repeatedly or circuits that keep failing
- Notice lights that flicker, dim, or buzz
- Are adding equipment, machinery, or a tenant space that needs more power
- Are renovating, expanding, or building new
- Need an older panel or electrical service upgraded
- Want backup power for storm outages
- Received an inspection or insurance notice about electrical work that needs correcting
If you see smoke or sparks, evacuate everyone and call 911 first. Then call us once it is safe.
- Power Capacity
Is Your Property Ready for More Power?
Adding equipment, tenants, or a larger space puts more demand on your electrical system. If your panel is full, breakers trip often, or the service is older than your current needs, an upgrade can protect your equipment and reduce downtime. A licensed electrician can assess your load and recommend the right solution.
Storm outages are part of doing business in New England. A properly sized backup generator keeps critical systems running, and our team can plan the generator and the electrical connection together. Planning heating or cooling work too? Because Arete handles both electrical and HVAC, we make sure the circuit is sized correctly before the equipment goes in. Explore our HVAC services

We hired Arete Electric to installed ductless air conditioning and upgrade our electric panel. They quoted the job to be completed in 2 days, we could not believe that they completed the job in that time. They did not rush, the quality of the work was higher than expected, great team of electricians. Fully professional, and respectful of our home - thinking of details I wouldn’t have not have thought of, but now notice and appreciate. I would recommend them to anyone looking to have electrical or air conditioning installationPosted on Google![]()

We were very happy with the quality of their work.Posted on Google![]()

If honesty, fair prices, transparency, empathy and integrity are what you are looking for in an electric/HVAC company, look no further than Arete Electric! I cannot recommend them more! My very old heater broke in the coldest winter we’ve had in years. Another electrician I called recommended Arete Electric . Tom quickly got to work diagnosing and ordering a replacement heater and quoted me a price way below what I ever expected, and I’ve had to replace one in a previous house. This also included replacing a light switch and a doorbell. Since the heater would be ready to pick up the next day, I would be without heat. Tom drove out to buy and install a couple of high quality space heaters to get me through the night. The next day, work was done efficiently and quickly and I have not had a problem since! I was so fortunate to find them, this is my electric/HVAC company for life!!Posted on Google![]()

We hired Arete Electric to upgrade our electrical output from 100 to 200 amps this past summer in order to make our house compatible for a new central air system. We could not have been happier with this decision because not only did Tom and his crew do an amazing job at the electrical upgrade, but we were so impressed with the job they did, we ended up hiring them to install our central air system. Arete Electric was polite, prompt, professional and very knowledgeable in their craft. We couldn't be any happier with the work that Arete completed for us and we will definitely be using them for any further electrical jobs we may have in the future. Thanks again TomPosted on Google![]()

I purchased a heat pump system from a company that no longer works in residential systems. I found this company from a social media request, and they’ve been fantastic. I bring them in annually to inspect my system, and they’re always thorough and great to work with.Posted on Google![]()

Precise, prompt, and professional do not begin to express the wonderful experience I just had with Arete Electric and HVAC. Having purchased an electric vehicle, I needed to have installed an EV charging station, outside my house and next to the driveway. My anxiety was high, and my knowledge of electricity is limited to the shocks I get when touch the wrong wires. To my pleasant surprise, the owner himself, Tom, made the initial service call and answered every question thoroughly to m satisfaction. We set a date for the installation, and it went without a hiccup or issue. He worked side by side his installers digging the trench, helping to run the wires, make the cement, and even cut and stained the post personally. He rounds out his team with his wife who remained in constant contact with me, making sure that all my needs were met. Arete Electric and HVAC has earned my vote as southern NH's best electric company. Thank you, Tom, and team. Doug Robinson, Derry
