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."

"Worst experience working with a contractor we have ever had. Lack of communication was astounding. Reached out to start the project on our tiny front lawn in June/July. Didn't start planting until mid October. Was told there were 5 jobs in front of ours. Ignored photos of exactly what we wanted. Finish product is passable at best. Would not recommend."

Jeff Veglia Remodeling was established in 1987 offering full scale remodeling and tile services. This business was built on honesty, integrity, and quality to all clients. Our reputation is based on superior quality at a competitive price and most importantly we listen to our customers. We serve Massachusetts. Please email or call rather than Message Center on Angie's List.

"Veglia Remodeling was wonderful to work with. Jeff gave me an estimate for the labor/work on my bathroom remodel. He also suggested vendors to work with and suggested meeting them to choose materials (which was the other cost of course). That was very helpful. Jeff was always available via text or phone. Mostly text. He was the point person if I had concerns. Always gracious. Happy to weigh in if I wasn't sure about something. He has a number of people who he works with and they were all very professional and everyone always cleaned up when they left for the day. I felt very fortunate to have Jeff commit to my project since my bathroom is extremely small (two people standing in it is a crowd) and it can be tough to find someone who will work on a small project."

Bathroom Fan Installation questions, answered by experts

You’ll find the backdraft damper near the top of the range hood (where it connects to the ductwork). However, some range hoods also have a second damper, which is located close to the roof or exterior wall where the ductwork ends. If you don’t see a damper in either of these places, you might not have one.

Fan power is measured by CFM, or cubic feet per minute. For every 1,000 feet of square footage in your attic, you need a minimum of 700 CFM. Steeper roofs may need larger fans or about 840 CFM.  You can figure the size of attic fan you need by multiplying the square footage of your attic floor by 0.7. (multiply by 1.2 for a steep roof and 1.15 for a dark roof). That number is the CFM required for your fan to run efficiently.

DIY is possible for basic replacements. Professional installation ensures proper wiring and venting.

Your bathroom exhaust fan shouldn't be loud. However, bath fans come in a wide variety of models, price points, and loudness characteristics, and yours may be louder or quieter than others you notice. Economy models tend to be the noisiest, with levels of 4.0 sones or more, which is about the sound of an electric shaver, while some high-end models can be barely audible. 

Most installations take 3-6 hours, but complex electrical wiring or additional attic ventilation work may extend the timeframe.
