Smart home upgrades — and everything else your home needs.

Start with our flagship Smart Home & Energy Tech install — done in a single visit — then go deeper with full retrofits across insulation, HVAC, windows, and solar, all organized by one trusted team.

01

Inspector Report & Oversight

Independent quality assurance for any retrofit — whether we organized the work or you hired your own contractor. We inspect, document, and oversee the job so you know it's done right.

What's included

  • On-site inspections at key project milestones
  • Detailed written report with photos and findings
  • Punch lists and remediation follow-through
  • Code, permit, and incentive-program compliance checks
  • Independent oversight of third-party contractors
  • Final walkthrough sign-off
Why it matters: An unbiased set of eyes on the work — protecting your investment and giving you leverage if anything needs to be corrected.

02

Smart Home & Energy Tech

Easiest place to start

Our flagship service — a curated bundle of smart, energy-saving devices we source, install, and set up for you in a single visit. The fastest way to start saving with no major construction.

What's included

  • Smart thermostats (Ecobee, Nest, Sensi)
  • Whole-home LED lighting & smart switches
  • Smart plugs, power strips & vampire-load eliminators
  • Leak, freeze & smoke/CO smart sensors
  • Real-time energy monitors (Sense, Emporia)
  • Smart EV charger setup & app configuration
Why it matters: A fast, low-disruption way to start saving — most installs are done in a day and start cutting bills immediately.

03

Insulation & Air Sealing

Most homes leak warm air in winter and cool air in summer. Sealing and insulating is the highest-ROI deeper retrofit you can make.

What's included

  • Attic blown-in cellulose & fiberglass
  • Wall cavity insulation
  • Basement and rim joist sealing
  • Blower-door testing & verification
Why it matters: Typical homeowners cut heating & cooling use by 15–30% after a full air-seal.

04

HVAC & Heat Pumps

Modern cold-climate heat pumps deliver heating and cooling on a single high-efficiency system — often replacing both a furnace and an AC.

What's included

  • Cold-climate ducted heat pumps
  • Ductless mini-split installations
  • High-efficiency furnace and AC replacements
  • Ductwork repair, sealing & balancing
Why it matters: Quieter operation, even temperatures, and major bill reductions versus electric resistance or oil heat.

05

Windows & Doors

Old single-pane windows and weatherworn doors are often the most obvious source of cold spots and street noise.

What's included

  • Energy Star double & triple-pane windows
  • Insulated exterior doors
  • Weatherstripping and trim repair
  • Storm door installation
Why it matters: Better comfort by the windows, fewer drafts, and a quieter, more secure home.

06

Solar & Electrical Upgrades

Once your home is efficient, solar and an updated electrical system unlock the next tier of savings — and prepare you for an EV future.

What's included

  • Rooftop solar PV systems
  • Main service panel upgrades
  • Level 2 EV charger installation
  • Battery storage consultations
Why it matters: Lock in long-term electricity costs and tap into available federal and local incentives.
