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."

"Nexus finished a basement (plaster walls, drywall ceiling, vinyl flooring, lighting and baseboards) and remodeled a bathroom (tile, drywall, tub/toilet/vanity installation). Caroline was great to work with. She kept us informed at each step of the way, and was communicative about deadlines and decisions that needed to be made. The crew was very pleasant to have in our home; though the project was disruptive they were very courteous at all times and made sure we were comfortable in the house while work was going on. The basement and bathroom came out beautifully. Would hire again."

Bathroom Fan Installation questions, answered by experts

Yes, most services include ductwork and venting to ensure adequate airflow. Confirm with your contractor.

The square footage of your room will dictate the correct ceiling fan blade size. For example: 

  • Rooms smaller than 75 square feet require a fan that is 29 to 36 inches.

  • Rooms up to 175 square feet require 42- to 48-inch fans.

  • Rooms up to 350 square feet require 52- to 56-inch fans.

  • Expansive spaces over 350 square feet need a fan larger than 60 inches.

You might have dampers if you have a ducted heating and cooling system. To find out for sure, find the main trunk line on your HVAC unit, then look for levers or handles on the ductwork. Contact a local HVAC professional if you can’t find any dampers or want to install some.

Every municipality has its own codes. But generally speaking, all bathrooms must have some ventilation, whether it's a fan or a window. Check your local building codes before doing any bathroom fan installation to make sure you are meeting the code requirements. A reputable electrician or bathroom fan installer will be able to answer this question.

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