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."

"I requested Steve to do some electrical work around the house (I am not handy) based on some positive reviews i saw online. - Steve came promptly at the appointed time. Was very polite and friendly .. - Work I needed was -- new circuit to be installed for my sump pump (the old circuit has too many appliances attached to it and was tripping) -- An outdoor floodlight had shattered - wanted to get a new one installed at a slightly higher location -- Had some electrical outlets in some very tight spaces that i wanted to replace with fixtures that would not break -- a light in a very tight space was not working (an earlier electrical contractor had "mis-wired" it. Steve did all of this during the course of about 6 hours. He was friendly, efficient and cleaned up everything after the job. I would hire Steve again in a heartbeat for any electrical work. PS: I do not know Steve - i hired him based on the positive online reviews I saw and his proximity to my house - I was definitely apprehensive but he worked out great. Hopefully this positive review will serve some other homeowner in good stead too !"

Electrical questions, answered by experts

You can plug your electric car into a regular 120-volt household outlet only if you’re using a Level 1 charger. This method is slower and may take several days to fully charge your EV. For faster charging, you’ll need a Level 2 charger, which requires a 220- or 240-volt outlet.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

Window ACs use 500 to 1,400 watts per hour of electricity, while mini-splits use 500 to 700 watts per hour. However, if you need to cool multiple zones in your house, your mini-split can use as much as 2,000 watts per hour. How often you run your system will impact how much electricity you use (and how much you pay per month).

You can run a small or basic standard-size refrigerator on a 15-amp circuit. But you should plug a modern, standard-size refrigerator into a 20-amp dedicated circuit. The refrigerator needs to be on a dedicated circuit, meaning it is the only appliance and outlet on that circuit breaker. This method prevents tripping the breaker and reduces the chance of an electrical fire

Just as fluorescent lights are more efficient than incandescent lights, LED lights are more efficient to run than fluorescent lights. The specifics will vary from product to product, but LED lights are typically twice as efficient as equivalent fluorescent lights. A 13-watt CFL bulb can replace a 60-watt incandescent bulb, but a 6- to 8-watt LED bulb can offer the same amount of brightness. Fluorescent lights offer about 50 lumens per watt, while LEDs offer about 100 lumens per watt. LED light bulbs typically last two to three times as long as CFL bulbs, too.
