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

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.

To ensure batteries stop charging when they’re full, you’ll need to install a charge controller that determines when the battery is full. Once the battery is fully charged, the charge controller will stop the energy flow or divert the energy to the grid or other appliances. Without a charge controller, the battery may continue to charge, which can lead to less productivity and potential damage.

You can use a double-pole switch for a regular light fixture, but it's unnecessary and won’t be the most efficient choice. A single-pole switch works perfectly for standard lights. Double-pole handle high-power appliances that require both hot wires to be disconnected. Using a single-pole switch for regular lights is more cost-effective, simpler, and more common in residential settings.

The National Electrical Code (NEC) places a limit of eight outlets on one 15-amp circuit to maintain electrical load values below 80% of the breaker switch’s capacity. To ensure the safety of your home’s electrical system and remain up to code, do not add additional outlets to a 15-amp circuit above the legal limit.

No, outdoor outlets are not required to be on a separate circuit. However, you should always defer to local electrical codes when making decisions about how to install your new outlet. An experienced local electrician will be able to inform you of all codes and requirements in place at your home.
