Why efficiency
Your home is your biggest bill. Nobody manages it.
The average American home spends thousands a year on energy — and roughly half of it goes to heating and cooling equipment that's a decade or more out of date. Old systems quietly lose 2–3% efficiency every year while utility rates climb about 4%. You feel it every month; you just never see it itemized.
Nu Home treats your house like the investment it is: one plan that upgrades the systems doing the most damage, funded as much as possible by the rebate programs your utility already runs.
Aging equipment decays
A 15-year-old AC or furnace can waste a third of every energy dollar it touches.
Rates only go one way
Utility prices have climbed ~4% a year. Waste compounds — so do savings.
Rebate money goes unclaimed
States and utilities budget billions for efficiency upgrades. Most homeowners never file.
The Nu Home Efficiency Plan
One plan. Every dollar accounted for.
AI finds the waste
Answer a few questions. Nu Intelligence analyzes your home's profile and utility usage to pinpoint which systems are costing you most — and what fixing them is worth.
We find every dollar
The plan prices your upgrade around real utility rates and conservative savings math — flags every incentive your address qualifies for, and in MA & NY we file the paperwork ourselves.
Local pros install in days
A licensed, insured installer from our vetted local network completes the upgrade — typically 1–3 days — and your home starts paying you back immediately.

Nu Intelligence
AI that watches the waste you'd never see.
Your home talks — through sensors, usage patterns and a hundred small signals. Nu Intelligence listens 24/7: catching the AC fighting an open window, the appliance drifting out of spec, the cheaper rate window you could be using. In plain English, before the bill arrives.
Local hands, national standards
The best local installers, held to our standard.
Every install is performed by licensed, insured local professionals who work your market every day — and earn their place in the Nu Home network by meeting our design, quality and cleanliness standards on every job.
Homeowners first
Real homes. Smaller bills.
“Our oil bill was eating us alive. Nu Home designed the heat pump system, got the rebates approved before install, and the crew was done in two days. The house has never been this comfortable.”
“They found rebate money we had no idea existed and handled every form. The app catching our AC running with a window open — that alone is paying for the alarm system.”
“No pressure, just a clear plan with real numbers. Our August electric bill dropped the very first summer after the new system and attic insulation went in.”
