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+."

Generator Install questions, answered by experts

No, this is extremely dangerous, often illegal, and you should never attempt it. If you connect your generator to your home without a transfer switch, the generated power can backfeed, essentially flowing back into the utility lines. Backfeeding exposes a significant threat of fatalities or harm to you and utility personnel, in addition to jeopardizing the structural integrity of your home.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

In most cases, there are no tax credits available for home generators. However, that’s a general statement that applies to federal tax credits, so you might have access to state or local tax incentives. You can check the Database of State Incentives for Renewables & Efficiency (DSIRE) for more information about your area. If you hire a reliable home generator installer, they should also know if there are any state or local perks you can use to reduce your installation costs, including tax breaks and rebates.

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit
