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 called Integrity Electrical after several outlets in the house failed, including the one for the refrigerator.

"Mike put in a bunch of recessed lights in our home, which made all the difference. He was communicative and did a proper job, was available and flexible with our timing and did the work at a good price. He even fixed some grounding for our washing machine before we even hired him! Would definitely work with him again, can highly recommend."

Since 1979, we've provided the highest quality protection against electrical, plumbing, heating, cooling and drain problems for residential, commercial and properties in the Merrimack Valley. At MillTown Plumbing, Heating, HVAC, and Drain Cleaning, we're a family owned and operated business. We know the value of fast service, from a professional and reliable team. Give us a call today at (617) 725-2674! We look forward to serving you.

"STAY AWAY. Numerous issues and they will cost you more money without you knowing it. I just found out that I was on a **DO NOT SERVICE** list (after all the grief they have given me.) I am ticked off. Here is a summary due to the character limit: 1. They installed a faulty HTP tankless hybrid water heater. I argued with them for what I think was a good year before a HTP tech finally determined that I was right. Replaced it with a Rinnai RUR199in. 2. They took (stole) my oval ductwork and replaced it. I was fine with the replacement. I looked the other way but it was expensive and they never asked - they just hauled it away. Most homeowners probably do not realize how expensive and unusual that oval ductwork is. I could have even recycled it at a profit. 3. I recommended them to a neighbor only to find cops all over their home one day. Their plumber stole their special needs kids controlled medications after having them go into other rooms to turn on and off the faucets. I just chalked it up to a bad apple. 4. HUGE ROOKIE mistake. They short-cycled the new air handler. Vent was right next to the main return (2in. away.) Unecessary wear and tear, high electric and gas usage, and discomfort. Whatever was coming out was immediately suck back in. Unfortunately I did not realize this until a couple years later. 5. HUGE ROOKIE mistake. They never installed the 2-stage wiring. See directly above. Look it up. HUGE discrepancies in temperatures and sky high bills. Premature wear and tear. I wrote Freddy Jr. about this which might be the reason why I am on their list. But still, that is their job to get it right and not mine. Most people would have no clue for the life of their system. 6. They did not hook up the high-limit kill switch/float on the condensation pump which led to a flood and destroyed antiques. I hooked it up in less than 10 minutes. 7. I was told one day that the original manger was fired because he was skimming clients from the company. 8. There is no check valve on the recirculation line which they installed on the new tankless they replaced. I believe it is code and now I have to hire someone else ([business name removed]) to fix their screwup which likely killed my internal recirculation pump. Again, unecessary wear and tear along with high energy bills. I was willing to look the other way on so many things but the truth is they get away with this because most homeowners do not know any better. In other cases, I figured that no one is perfect and we all make mistakes. But then to find out that I was blacklisted a few years later because I called them out on their BS after I needed their help yesterday? The only thing I can think is that I ended up costing them more money on things they should have done properly in the first place. It is a company that needs better oversight and apparently has awful management. I am not bragging but I have an advanced engineeering background creating petroleum engineering training material for big oil (aka plumbing on steroids--makes this look like childs play), programming, developing systems for hydroponics, working with heat and waste recovery systems, fixing combustion engines, and building computers for over 20 years. My point is that I noticed a lot of things that most people would overlook because I know how many things work. I called them out and that is the only explanation as to why I could have been blacklisted. But do yourself a favor and go with [business name removed] or [business name removed] instead. It is not to say that others cannot screw up, but this is my experience with them and the straw that broke the camels back. Mention that you read this here and thank you. Perhaps the next company will not mess you up under the guise/protection of teamsters and protectionist unions that overcharge with ridiculous licensing requirements that ends up meani..."

"Tim came to my house on an emergency call due to a total loss of lights. Our outside electrical line was frayed - letting moisture into the circuit box. He discovered it needed repair right away and made plans to come the following morning. I had texted him later in the day to say the power had gone off again. He came back to the house that night because he was worried about a fire and did the WHOLE job - it took about 3 hours with a crew. Exemplary service - I highly recommend."

Electrical questions, answered by experts

The most common reason a GFCI outlet would trip even when nothing is plugged in is if there’s a problem at the circuit breaker end. This could be an overloaded circuit, with too many appliances plugged into it, or another type of fault. If a GFCI outlet keeps tripping, it can also be because it is faulty and needs replacing.

The size of your home will help determine the size of your electrical panel. Usually, the decision comes down to a 100-amp electrical panel versus a 200-amp panel. Smaller homes, especially those without an HVAC system, may be able to get by with a 100-amp panel. 

If you have a larger home or need to power AC, a 200-amp panel should be the best fit. It’s unlikely that you’ll need a larger panel than that unless you have a larger home or unique electrical needs, but an electrician can help you make the final call.

Yes, a light switch still has power even when switched off. Switches only interrupt or continue the flow of electricity into a fixture or outlet; they do not shut off the power flowing into the wire. The only way to shut off power in a light switch is to turn off the power at the circuit breaker.

Yes, you can plug an extension cord or an outlet extender into a GFCI outlet. The GFCI outlet will still be able to protect your system in the same way.

Compared to amps, volts, and watts, ohms are a different kind of measurement, though also very common. Ohms show the resistance of materials like wiring: How much they impede the flow of electrons. The reason household wiring is usually copper or aluminum is that these materials are affordable and also have lower ohms, which means low resistance/high conductivity.
