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."

FAQs for electrical wiring or panel upgrade projects in Groton, MA

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
