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."

Electrical questions, answered by experts

There are a few telltale signs that it’s time for a replacement. You should consider an upgrade if:

  • Your panel is over 25 years old

  • You’re adding a new electrical system

  • Your current system doesn’t offer the power you need

  • Your home is a jungle of power strips

You can check if an electrician is licensed in New York by using the online license verification search tool offered by the New York State Education Department. The database is updated daily and gives you the option of searching by license number, contractor name, or the name of the business.

An AC disconnect, also known as a switch box or fuse box, is a safety switch that allows the AC’s electrical supply to be turned off from the outside, usually done by a mechanical contractor coming to work on your unit. The box is protected from the weather by a cover or may be designed as a pull-out unit. Your local code determines where the AC disconnect must be mounted, but it's usually close to your outdoor AC unit.

Before the widespread use of PVC, affixing a ground wire to plumbing pipes was generally considered to be an acceptable workaround. Nowadays, not so much. There are plenty of nonmetallic water pipes and fittings out there, so any ground previously provided by the metallic piping would be interrupted in these cases, which is dangerous.

Three-way switches are only replaceable with three-way switches. A single-pole switch won't work if you replace one or more of a pair of three-way switches. By electrical code, three-way switch configurations are necessary at the top and bottom of a staircase between residential floors.
