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."

Electrical questions, answered by experts

If you've ever tried to run your dishwasher while drying your hair, you’ll understand why dedicated circuits are essential for preventing blown fuses. Appliances that require more electricity than the circuit can handle could blow fuses, trip breakers, overheat, and risk an electrical fire. 

Having a dedicated circuit ensures that your appliance gets the current it needs without overloading the other circuits in your home.

Yes—if a breaker is old or damaged, it might not be able to detect power surges or electrical overload. If that happens, the breaker won’t trip. Instead, it will begin to overheat, putting your electrical system at risk of fire or total electrical failure. Circuit breakers don’t last forever, so you can proactively replace old or damaged breakers before they stop working.

Poorly designed and incorrectly installed outlets can create an electrical fire hazard, as do some phone chargers and adapters that plug into these outlets. However, most outlets are perfectly safe as long as they remain in working condition. Keep an eye on what you are plugging into the outlet and stay alert for signs of outlet malfunction, like sparks, burning smell, or frequent circuit tripping.

To ensure batteries stop charging when they’re full, you’ll need to install a charge controller that determines when the battery is full. Once the battery is fully charged, the charge controller will stop the energy flow or divert the energy to the grid or other appliances. Without a charge controller, the battery may continue to charge, which can lead to less productivity and potential damage.

This depends on how many outlets you have and the current status of your electrical system. The cost to ground an outlet clocks in at $75 to $480 per outlet, so multiply that by the number of outlets in your home to arrive at a rough estimate. However, this is for simple projects with no obvious issues with the system. Your final bill could vary widely from your calculations.
