Why Lexington homeowners choose Nexis
From colonials near Lexington Center to mid-century modern homes in neighborhoods like Five Fields and Peacock Farm, Lexington homes have real Massachusetts energy costs and real savings on the table. Nexis designs, permits, installs and services solar, batteries, heat pumps, roofing and electrical for Lexington families, and we handle the Mass Save and SMART paperwork so you don't have to. Many Lexington homes are larger and older, which makes a right-sized heat pump and a well-designed solar array the biggest levers on the bill. Every project here includes the town building and electrical permits and, for solar, the Eversource interconnection application; we prepare and submit all of it.
Because we're licensed across five trades in-house, your solar, roof, panel and heat-pump work happens on one timeline with one accountable team — not a chain of subcontractors pointing fingers.

What our customers say
Nexis handled our solar, panel upgrade and battery as one project — one crew, one timeline, and they filed every rebate. Painless.
They actually knew the Mass Save program cold and got us the full heat-pump rebate. No other quote came close on value.
Forbes #1 for a reason. Professional, licensed, and they didn't disappear after the install like our last installer did.
