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."

We pride our company on reliability, great communication, integrity, and quality work. We are experts in our trade and will do our best to keep you as educated as we can on your particular task or project. We look forward to earning your business!

"Carmen and his team did a great job on helping me upgrade my panel as well as change my meter box. I also had an old wooden mast that they changed out and replaced with a much nicer modern fixture which was great. My house was old and I actually bought it many years ago as a forclosure renovation. So some of the previous work was old and not done correctly. Carmen, Shawn and his team were great to work with. I was worried that no one would take the job because the previous owner had not done a great job. Carmen and his team dived in and made all of the main wiring to the house beautiful and secure and safe. I would use them again for any electrical work big or small. In addition I would add his team comes very well prepared. They have every tool imaginable for the job and are ready to go. I am so happy I choose them. A local neighbor recommended him to me. I looked at their breaker panel and liked how neatly it was done. Thats why I choose Carmen."

"Wilmer was absolutely stellar in his project to replace my old oil boiler with a a gas one. I shopped around heavily and Wilmer provided me the best quote and walked me through my setup to help me understand it before I ever committed to giving him the job. He was incredibly friendly, honest and knowledgeable. He provided communication throughout the project and was quick to get back to me on any questions I had. The work got done in 3 days as he promised. His team showed up on time, worked hard and cleaned up after themselves. The quality of the work is top notch. I am a very happy customer and would absolutely love to do business with WR again. "

Generator Install questions, answered by experts

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

As long as your generator is used as recommended by the manufacturer, it’s safe to use for auxiliary power. Make sure that fuel powered generators are used outdoors and that the fumes dissipate away from your home. A professional generator installer will ensure your generator’s placement and set-up meets safety standards when installing or repairing your back-up power source.

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.
