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."

"Wish I could give 0 stars. A worker in one of their company vehicles was in a left only lane, while I was in a lane to go straight. There was no room for him to merge into my lane (traffic was a bit heavy). He continued to go into my lane, without a care and almost completely rammed me off the road. I am in a small car and the truck could’ve done severe damage in that moment. If this is how your employees are on the road, I don’t want to see how they are in the work field."

Electrical questions, answered by experts

A safe home is priceless, so upgrading your electrical panel, if you need to, is always worth the cost. The primary benefit of upgrading your electrical panel is preventing fire and other electrical hazards. A malfunctioning panel can cause electrical fires and other issues if not resolved quickly, so upgrading your panel is essential to keep household members safe.

Aside from safety and increased peace of mind, this upgrade guarantees a steady flow of electricity to all corners of your home. That way, you can say goodbye to flickering lights and flipping breakers constantly. An upgraded electrical panel lets you connect additional appliances without worrying about tripping your breaker or blowing fuses.

Yes, Christmas lights on a timer are just as safe as any other Christmas lights are. Most fires caused by holiday lights are due to damage to the strings of lights themselves or from too many lights being plugged into one circuit.

You can make a pigtail with either thermoplastic high-heat-resistant nylon-coated (THHN) wire or non-metallic (NM) cable, often referred to as “Romex.” Each pigtail requires a neutral wire, a ground wire, and a live wire. The gauge of your pigtail wires must match the gauge of those on the device. 

No, because amps and volts measure very different things. However, you can use basic equations to find amps or volts by using data about one of the measurements to calculate the other.

Unless you have prior electrical experience, it’s best to hire a professional to install your new thermostat for you. Improper installation can damage wiring, lead to a blown fuse, and more.
