Nelson Electric & Air

Nelson Electric & Air maintains a 5-star rating from 95 verified client reviews while serving Londonderry, Derry, Manchester, and the broader Southern New Hampshire region from their Londonderry base. As a licensed electrical contractor, the team handles both residential and light commercial projects, covering everything from routine panel upgrades to specialized installations including EV charging stations and home automation systems. Their service menu explicitly lists emergency response among the offerings, and the company provides financing options for larger projects.

What distinguishes Nelson Electric & Air from neighboring contractors is their breadth of specialized installation capabilities. The company handles A/C system wiring for homes, indoor and outdoor lighting design and installation, hot tub and pool electrical wiring, and home automation integration. This combination of trades under one roof allows homeowners undertaking renovation projects to coordinate multiple electrical upgrades through a single provider rather than contacting separate specialists for each subsystem.

Multiple reviewers specifically call out technician Michael by name, describing his methodical approach and willingness to explain each step of the work. One homeowner recounted Michael installing an exterior outlet with new wiring run from the main electrical panel, taking time to clarify the entire process. Another client noted Michael upgraded their 100-amp electrical panel to 200 amps, with the work so thorough that they requested recessed lighting throughout their house. A third reviewer praised Michael for handling a remote-site hot tub installation with a custom electrical cover solution.
