  • Should You Attempt Electrical Installation Yourself?

    Even if you have experience with some electrical repairs, we always recommend that you hire a licensed electrician to handle any new installation needs. Electricity is safe when handled properly. Our team of professionals must pass rigorous training and certification in order to work on electrical systems safely and understand the requirements of current building codes and safety standards.

    As an added benefit, we are fully insured and stand behind all of our work. If there’s ever an issue with your installation we’ll work with your town inspector, and more importantly, you, to rectify any problems.

  • Are your electricians licensed to perform electrical installations in New Hampshire, Massachusetts, and Maine?

    Yes. Our electricians hold all required licenses and certifications for NH, MA, and ME. We adhere to all applicable state electrical codes, permitting regulations, and industry-standard safety practices.

  • Do you ensure compliance with code and safety standards during installation?

    Yes. All installations are performed by licensed professionals trained to meet current state and national electrical code standards. We also handle any required permits and inspections to guarantee your installation is safe, compliant, and built to last.

  • Why should I hire a professional electrician instead of attempting a DIY electrical installation?

    Electrical installation is complex and risky. Mistakes can lead to safety hazards, code violations, or future failures. Licensed professionals have the necessary training, experience, and tools to ensure safe, legal, and durable installation. Hiring a professional helps give you peace of mind and protects your home from potential hazards.

We called several plumbers and I got “we are too busy” and “it’s too small of a job”. Not with heritage though! They were able to get us on the schedule in a timely manner and helped us with our plumbing issue. Thank you Zach! Zach was quick and professional! Will definitely use again!

I’ve dealt with Heritage for many years because of their dependability. They are not the cheapest, for sure, but if you need a plumbing or HVAC system installed or serviced/repaired, there’s none better. I needed repairs to be done on slim duct covers that were damaged after having siding installed on my home. I called Heritage because they were the company that installed the original mini-split system in my house several years earlier. John Lindonen and another technician (unfortunately, I don’t remember his name) showed up as committed and did the repair work. They were very thorough, explaining every issue to me and answered all of my questions. They were polite, and extremely knowledgeable. I wouldn’t hesitate to recommend these guys to my family or friends.

The AI interactive was ok but screwed up my ph# so never got a call. However, Camile arrived and spent time discussing my points and activities performed, helped me tremendously and ultimately didn’t need service. He was professional, informative, and transparent so Heritage, please acknowledge his great service!

Derek Clark from Heritage Home Services did a fantastic job for us. He installed a new garbage disposal and fixed a leaky bathroom faucet quickly and efficiently. He was professional, knowledgeable, and pleasant to have in our home. He took the time to explain everything, completed the work with care, and left the area clean when he was finished. We really appreciated his friendly attitude and excellent service. We’d definitely recommend Derek and Heritage Home Services to anyone looking for a reliable plumber!

Nicholas Silva’s diagnosis is good and he has a good background, knowledge and experience in plumbing. It did not take much time for him to identify my problem. But, I think his company needs to be more reasonable and realistic in quoting.

Had Heritage replace my 87 year old fathers AC systems and they did a fabulous job. Dexter from the company was very easy to work with and they did the work in record time, since there was heat wave going on and my dad needed to be up and running fast. I would recommend them, they have a good history of superb customer service.

We contracted Heritage to clean mold buildup from our split AC system. We had Owen from the company visit our home for the service and he was very thorough and professional. He made sure everything was clean and functioning properly.
