The Right Way, For The Right Reasons

Our story began in 2012, when Tom Parolisi started Parolisi Electric with a commitment to quality workmanship, honest service, and doing things the right way.

Over the years, the business grew—but so did the vision for what it could become.

In 2021, Parolisi Electric was rebranded as Arete Electric & HVAC Services with a purpose: to build something bigger than Tom Parolisi.

Arete was created to become more than a company built around one person. The goal was to build a team, a culture, and an organization with a lasting impact—a place where people can develop their skills, build meaningful careers, support their families, and take pride in being part of something bigger than themselves.

That purpose extends beyond our own team. We believe a successful business has a responsibility to serve its customers well, strengthen its community, and use its success to help others.

The name Arete reflects that mission. It represents the pursuit of excellence—not only in the electrical and HVAC work we perform, but in how we treat people, how we develop our team, and the kind of company we strive to become.

Licensed Electrician

One Company for Electrical and HVAC in NH & MA

Most contractors specialize in one trade. Arete brings licensed electrical and HVAC expertise together under one roof — which matters most on the projects that count: heat pumps, mini-splits, panel upgrades, generators, and EV chargers. Instead of coordinating two separate contractors, you get one team that understands how your electrical system and comfort system work together.

HVAC - Mini Splits

Mini-splits are one of our most-requested installs — ideal for additions, finished attics, or any room that’s hard to heat and cool efficiently. Ductless systems mean no ductwork, faster installs, and room-by-room control.

Heat Pumps

Heat pumps deliver efficient heating and cooling in one system. As a Mass Save® Heat Pump Certified Contractor, we can help Massachusetts homeowners access rebates on a qualifying heat pump install.

Electrical Panel & Service Upgrades

Outdated or overloaded panels are one of the most common reasons NH and MA homeowners call us. We offer 100-amp to 200-amp service upgrades that bring your home up to code and ready for EV chargers, generators, or renovations.

Generators

New England storms don’t wait. We install whole-home and commercial backup generators, sized and installed by licensed electricians.

EV Chargers

As more homeowners go electric, we install home EV chargers with the panel capacity to support them safely.

Higher-Value Electrical Projects

Beyond repairs, we handle the bigger jobs: full electrical renovations, dedicated circuits for workshops, EVs, or home offices, and code corrections that bring older wiring up to current standards. If a previous electrician’s work didn’t pass inspection or doesn’t meet code, we’ll fix it right.

Residential Electrical

Troubleshooting, dedicated circuits, lighting, renovations, and code corrections — handled by licensed electricians who respect your home. We do new construction not just additions but entire new home wiring

Commercial Electrical

Property managers, general contractors, and small businesses across Southern NH and Northern MA trust Arete for dependable, code-compliant work.

Why Choose One Company

Hiring one licensed contractor for both electrical and HVAC work means a single point of accountability, fewer scheduling delays, and a system designed to work together — especially important for heat pumps, mini-splits, and generators, which depend on properly sized electrical service.

What Our Customers Say on Google

Mike & Katie Metallo

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 installation

Andrew MT Moore

Arete Electric did an outstanding job in installing an electric charger in our garage.

Michele Meister

Tom and his team were great. Friendly, knowledgeable and got the work done in an efficient manner. They will definitely be our electricians for any work in the future.

Joanne James

Dan and Tyler were very polite and professional while installing our light fixtures. They took care in setting up and cleaning when they were finished even moving the furniture back in the original spots. They were eager to please us making sure everything was done as expected. We were very happy with the quality of their work.

Patricia Bearse

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!!

Luke Glinski

Arete Electric was outstanding in terms of quality of the work and the speed at which they were able to take on my large project. The professionalism speaks for itself in the image.

Erik Schelling

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 Tom

Carol Boire

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.

Doug Robinson

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

Frequently Asked Questions

Do you offer free estimates?

Yes, we provide free estimates for residential and commercial electrical and HVAC projects.

What areas do you serve?

Arete Electric & HVAC Services is based in Sandown, NH and serves Southern New Hampshire and Northern Massachusetts.

Do you install whole-home generators?

Yes — we install whole-home generators sized to your home or business, so you stay powered through New England outages.

Can you install an EV charger at my house?

Yes. We'll also evaluate whether your electrical panel has the capacity to support a charger or needs an upgrade first.

Are mini-splits a good fit for older homes without ductwork?

Yes. Mini-splits are ductless, so they're ideal for older homes, additions, and rooms that are difficult or expensive to connect to existing ductwork.

Do heat pumps qualify for rebates in Massachusetts?

Yes — as a Mass Save® Heat Pump Certified Contractor, we can help Massachusetts homeowners determine what rebates a qualifying heat pump installation may be eligible for.

How do I know if I need an electrical panel upgrade?

If your home still has a 100-amp panel and you're adding an EV charger, mini-splits, a generator, or other higher-load equipment, you likely need more capacity — a licensed electrician can evaluate your panel and recommend the right upgrade.

Can I install an EV charger without upgrading my panel?

Sometimes — it depends on your panel's existing capacity. We evaluate your electrical setup and let you know whether an upgrade is needed before installing the charger.

How do I know what size generator I need for my home?

Generator sizing depends on your home's square footage and which circuits or appliances you want to keep running during an outage — we assess this on-site as part of your free estimate.

What is a code correction and when is it needed?

A code correction fixes electrical work that doesn't meet current safety or code standards — often found during home inspections, renovations, or after a previous electrician's work. We identify and repair these issues to bring your system up to code.
