For emergency services, please call 781-933-6387. N.E.T.R., Inc. is here to help homeowners install the best heating and cooling systems that fits their needs. Since 1989, we’ve installed heating and cooling systems in Boston and its surrounding areas, tackling tough problems that our clients face. Our goal is to ensure our clients have energy efficient, quiet, reliable systems so they can live their lives to the fullest both at home and at work. Our dedication to our customers’ needs is what drives us each and every day. Our approach to temperature control and comfort has helped us become one of the most respected names in heating, cooling, and refrigeration in New England

"Before installing a mini-split, the sales person told me that I'd need to cut down an interior shelf to a specific height. I paid a handyman $400 to do exactly what the sales person instructed. Later on, N.E.T.R. came and did the installation; however, AFTER the installation, a technician told me that they hadn't accounted for the vent opening and closing and that the shelf would need to be further cut down. As you can imagine, this type of service is rather ridiculous. If they knew that the shelf would need further cutting, they should have NOT installed the unit. I have called N.E.T.R. six (6) times in three weeks, and no one has called me back about this issue. After paying for the unit and for a handyman, it's ridiculous that I have AC that is compromised because no one with the company thought to properly measure the space so that the work by the handyman could be done once. At this point, I'd like for N.E.T.R. to take care of this for me."

"Tim came to my house on an emergency call due to a total loss of lights. Our outside electrical line was frayed - letting moisture into the circuit box. He discovered it needed repair right away and made plans to come the following morning. I had texted him later in the day to say the power had gone off again. He came back to the house that night because he was worried about a fire and did the WHOLE job - it took about 3 hours with a crew. Exemplary service - I highly recommend."

Electrical questions, answered by experts

They can vary—a lot. For example, while the EU continues to move toward broader standardization, many different types of outlets still exist from country to country. Some local standards cared about polarization, and some didn’t. It’s similar to other countries around the world.

Generally, you’re less likely to find polarized outlets outside North America. However, alternative plugs and outlets often incorporate precautions so that accidentally touching live prongs on a plug is hard or impossible. You may also find interesting regulations overseas that limit the use of outlets in bathrooms or near sinks to decrease the chance of shock.

Yes, you can splice electrical wires together to make them longer. If you follow the proper safety protocols and match the correct colors, you can save yourself from getting a brand-new circuit and add length to your wires to get them where they need to go.

Type S or T fuses don’t require any special removal or installation tools. However, replacing a cartridge-style fuse is easier and safer when using a fuse-puller tool. All of these tools should be available anywhere you can buy fuses.

When converting a standard 120-volt outlet to a 240-volt outlet, the only components you can typically reuse are the existing electrical box and the hole in the wall. Everything else—including the wiring, breaker, and receptacle—should be replaced to ensure both safety and efficiency. Additionally, appliances designed for 240 volts have different plug configurations that won’t fit into a standard 120-volt outlet, making it necessary to install a compatible 240-volt receptacle.

In many cases, yes, upgrading your electrical panel can lower your electric bill. Upgrading an outdated electrical panel can make your home more energy-efficient, so you consume less electricity and spend less on utility bills. However, to see these savings, you’ll need to invest quite a bit. On average, installing a new electrical panel costs $1,200 to $2,000, with most people paying around $1,600.
