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."

"Had the misfortune of hiring Matt for a job and had the worst experience. Despite his initial promises of going above and beyond (such as conducting a thorough two-men system check and ensuring every connection was properly addressed), he only provided two brief 10-minute visits and presented another estimate that tripled the cost of the project. I strongly advise others to be cautious and avoid his services. This was a disappointing and unsatisfactory encounter - feeling scammed of $1000+."

Electrical questions, answered by experts

Before you start doing anything else, you must call your electric company to confirm their process. It is technically their meter that you’re moving, so there’s really no such thing as free rein. Moving the meter generally involves disconnecting power from the utility company, disconnecting the cables that run into your electrical panel, and dismounting the meter assembly. Once uninstalled, a handyperson will remount and reconnect the wiring in its new location.

The National Electric Code requires at least one GFCI outlet in each sectioned-off portion of a finished or unfinished basement and at least one GFCI outlet per circuit in a fully finished basement. There may be additional codes based on your local municipality and building department. A licensed electrician in your area will be familiar with the requirements and can ensure your home is up to code.

A wire stripping tool is the easiest way to strip sheathing or plastic insulation from electrical wires. A self-adjusting wire stripper cuts and removes the sheathing without damaging the core wire.

How far you can run underground electric depends on the wire gauge (generally AWG) and the circuit voltage. Too much voltage drop in an electrical circuit can negatively affect performance, so the smaller the voltage drop, the better. Ideally, it shouldn't exceed 3%. The smaller the wire and the longer the run, the more significant the voltage drop. 

For example, with a 120-volt circuit, you can run 60 feet of 12 AWG cable without losing more than 3% voltage. With a 240-volt circuit, you can run 120 feet of 12 AWG wire while maintaining a voltage drop of 3% or less.

The National Fire Protection Association reports that almost half of reported electrical fires are caused by electrical distribution and lighting equipment. The main culprit behind these fires is often frayed, worn, or faulty wiring, particularly in closed-off and concealed areas like attics, where fires can start and burn undetected for long periods.
