Generator Installation for Falmouth Homeowners
Automatic Standby Power
Whole-Home Coverage
Professionally Sized & Installed
For generator installation in Falmouth, homeowners turn to Aces Highlands: a Portland-based crew (508 Riverside St Unit 1) that is minutes from Cumberland County and already familiar with the homes, climate and codes here.
Maine storms knock out power when you need it most. Aces Highlands installs whole-house standby generators that switch on automatically — keeping your heat, water, and essentials running through any outage in Greater Portland and Southern Maine.
A standby generator sits permanently outside your home and starts automatically the moment the power goes out — no cords, no manual switching, no cold nights. We install Generac and other leading standby systems sized to cover your whole home or just the circuits that matter most: heating, well pump, refrigeration, sump pump, and lighting.
Every installation includes a properly sized generator, an automatic transfer switch wired to your electrical panel, and a fuel connection to natural gas or propane. We handle permitting, placement, and inspection so your system is safe, code-compliant, and ready before the next storm.
We start with a load assessment to recommend the right capacity for your needs and budget — no overspending on a unit larger than you need. We offer financing options on whole-house generators, and we provide ongoing maintenance to keep your backup power ready year-round. Contact us for a free estimate.

- A straight diagnosis and a clear price before we touch anything — no upsell
- Scheduling that moves quickly, because a home without heat or water cannot wait

Falmouth Homes and What They Need
Falmouth's housing is younger than most of Greater Portland. Census estimates put the median home here at 1986, and roughly 14 percent of homes have been built since 2010, many of them in newer subdivisions. The older layer is still real: about 14 percent of homes predate 1940 and about four in ten predate 1980, from Falmouth Foreside along Route 88 to West Falmouth Corner and Highland Lake. Around 80 percent of homes are single-family detached houses, and most are owner-occupied. In practice that means two very different kinds of job in one town: a newer colonial with PEX, a mechanical room and room for ductwork, and a Foreside house with copper or galvanized supply lines, tired shutoff valves and pinhole leaks that need tracing behind finished walls.
Power, Storms and Wiring in Falmouth
Central Maine Power serves Falmouth, and the town's tree-lined roads have taken real hits. In the January 1998 ice storm, Falmouth was among the Greater Portland towns that bore the brunt of the damage, and the December 2023 wind and rain storm left more than 56,000 Cumberland County customers without power at its height. Census estimates show about a third of Falmouth workers now work from home, which turns a two-day outage into lost work as well as a cold house, and makes a transfer switch or standby generator worth pricing before the next storm. The other trend is charging: short commutes into Portland suit electric vehicles, and many of the town's 1980s and 1990s houses have 100 or 150 amp panels already crowded with circuits. A load calculation shows whether a Level 2 EV charger in the garage fits on the existing service or needs an upgrade first.
Getting to Know Falmouth
The original town of Falmouth once encompassed what are now Portland, South Portland, Westbrook, and Cape Elizabeth — those communities were all carved out of it over time. Just offshore, Mackworth Island was Governor Percival Baxter's family retreat before he deeded it to the State of Maine in 1943; today it is famous for the "fairy houses" visitors build in its woods and for Baxter's stone-walled memorial to his Irish Setters.
Modern Falmouth is known for well-kept homes with high-end finishes — the kind of properties where clean line-set routing, tidy penetrations, and spotless job sites matter. That is how we work.
Local & Independent — Not a Franchise
Aces Highlands is a locally owned Portland, Maine company serving Falmouth — not a national franchise. Our techs are paid to do the job right, not to upsell — no commission structure pushes them toward extra work. We do the work you called us for, do it right, and earn the next call. That is the whole business model.
How a Standby Generator Works
- Standby generator — starts itself within seconds of an outage
- Automatic transfer switch — throws from utility to generator power
- Utility service — disconnected while the switch is on generator
- Feed to the panel — the switch, not the generator, connects to the house
- Weekly exercise cycle — runs itself briefly so it starts when needed
Homeowner Guide
Standby Generators: Sizing, Transfer Switches & Fault Lights
Maine loses power in a way most of the country doesn't — a January ice storm can mean days, not hours. A standby generator is one of the few electrical projects homeowners research almost as thoroughly as we do, so here's the technical part laid out plainly.

Codes & Permits for Generator Installation in Falmouth
Electrical work in Falmouth is licensed and permitted under Maine's Electricians' Examining Board, which adopted the 2026 National Electrical Code effective July 1, 2026. Confirmed live on the Code Enforcement Division page: the division is responsible for "Issuing all permits associated with construction projects (e.g., building, plumbing, heating, and electrical)" and requires a current Maine electrician's license before work is inspected. The division functions as Falmouth's Local Electrical Inspector under Maine's electrician licensing law (32 M.R.S. ch. 17); no individual inspector was named on the page. Shoreland zoning applies within 250 ft of any great pond, river, saltwater body, or coastal wetland, and within 100 ft of streams/brooks; permits are required for many activities in that zone.
- The electrical work on a generator (wiring, transfer equipment) is separate, licensed electrical work requiring a Maine electrician — it is not covered by the Fuel Board license, which covers only the fuel/appliance side. mainelegislature.org
- The Town of Eliot's current process treats generator installation as a building-permit item, not a separate electrical permit: 'A building permit is required for the installation of a generator... The Town will not issue a separate electrical permit for the generator,' while the electrical work itself must still be done by a Maine-licensed Master or Limited Electrician per state law. This illustrates that a corridor town's generator permit process can differ from its general electrical permit process. source
- 25 M.R.S. §2468 requires CO detectors near bedrooms based on occupancy/construction type; it does not specifically address standby generators, so it neither requires nor exempts a CO detector because a generator is present — the general occupancy-based requirement is what applies (see general facts). mainelegislature.org
- Central Maine Power (CMP), a subsidiary of Avangrid, describes itself as serving 'approximately 670,520 electricity customers in an 11,000 square-mile service area in central and southern Maine' — the region that contains the entire Augusta-to-York corridor. Consistent with this, South Portland's own permitting page requires a CMP account/work-order number on any electrical permit tied to a service change, and Buxton's electrical permit application has a dedicated field for the applicant's CMP account number. cmpco.com
How Aces Highlands Handles Generator Installation in Falmouth
- We wire standby generators to NEC Article 702's optional-standby rules, which includes a readily accessible emergency shutdown located outside the dwelling, not just at the unit itself.
- Gas and propane standby generators answer to the Maine Fuel Board as well as the electrical code, so we coordinate both approvals on the same install — Summit Natural Gas of Maine covers part of Falmouth for anyone going the natural-gas route.
- Clearances from windows, doors and fresh-air intakes follow the manufacturer's own installation instructions, which we confirm on-site before the pad goes in.

I can not recommend Sam and his team enough!! In a world of slow response times and cut corners they went above and beyond in every area, installing a new electrical panel for me. Their attention to detail and love of their craft truly sets them apart from the rest!

We have called Samuel for our electrical needs over the last few years and have always been impressed with professional and courteous attitude — installing extra outlets, installing new lights and ceiling fans, our whole house generator, charger for the electric car, even the hot tub!!! His price was fair, and never disappointed when work was completed.

Where to begin? These guys hooked up a sauna for me and did an amazing job, it was not a small job. Projects big or small, these guys are my go to. Responsive, reasonably priced, and professional. In a world where it is tough to get good service, I'm thrilled to have these guys in my phone.

Generator Installation FAQs
How fast does a standby generator turn on when the power goes out?
Typically within 10 to 30 seconds of a grid failure, the automatic transfer switch starts the generator and picks up your circuits — no one has to be home and nothing has to be plugged in. When utility power returns, it transfers back and shuts down on its own.
What size generator do I need for my house?
Essentials-only coverage (heat, well pump, refrigeration, sump pump, lights) often fits a 10-14 kW unit; whole-home coverage typically runs 18-26 kW. We perform a load assessment and size to what you actually need — never a bigger unit than the math supports.
How much does a whole-house generator cost installed?
Nationally, most installed standby systems run $9,000-$15,000 depending on capacity, fuel hookup, and site conditions, with essentials-only systems costing less. We provide a firm written quote after the load assessment, and financing is available.
Propane or natural gas — which fuel is better for a generator?
If your street has natural gas, it offers unlimited runtime without deliveries. Most of Maine runs on propane, which works excellently — we size the tank so the generator can run for days. Either way, we handle the fuel connection ourselves under our Maine gas licensing.
What maintenance does a standby generator need?
An annual service — oil and filter, spark plugs as needed, battery check, and a transfer-switch test — plus the weekly self-test the unit runs automatically. We offer ongoing maintenance so your generator is ready before every storm season, not discovered dead during one.
