The Best Home Generators in Brunswick, Maine: What Midcoast Homeowners Should Look For

When the power goes out on the Midcoast — and every Mainer knows it will, usually in the middle of a January nor'easter — the difference between a cold, dark house and business-as-usual comes down to two decisions: which generator you bought, and who installed it. If you've been searching for the best home generators in Brunswick, Maine, this guide walks through what actually matters when you compare brands, dealers, and installers in our corner of the state. 

Start With the Dealer, Not Just the Generator 

Most standby generators on the market today — Generac, Kohler, Briggs & Stratton — are well-engineered machines. What separates a generator that starts every time from one that fails during the third day of an outage is almost always the installation, the sizing, and the maintenance behind it. 

That's why the smartest question isn't "which generator is best?" but "who will stand behind it?" Look for a dealer that is factory-trained and certified on the equipment they sell, handles warranty work themselves rather than shipping it out, offers a real maintenance program, and answers the phone when a storm knocks out half the county at 2 a.m. 

Why Brunswick Homeowners Choose Best Home Generators 

We may be biased — but we can also point to the record. Best Home Generators was originally founded in 1994 as the Brunswick Home and Gardens Generator Division by Jesse Laffley, and after three decades of installing and wiring backup power across the Midcoast, we became Best Home Generators in 2024. Same team, newly located at 314 Bath Road in Brunswick, sharper focus. 

Here's what that experience translates to for your home: 

• All three major brands under one roof. We sell and service Generac, Kohler, and Briggs & Stratton — so our sizing recommendation is based on your house, not on the only brand we happen to carry. 

• Kohler Titanium Dealer status. That's a factory designation, not a slogan — it reflects certified training and service standards on Kohler's residential standby line. 

• Generac PowerPRO Elite status. Generac's Elite designation recognizes dealers who meet its certified training and service standards on Generac's residential standby line. 

• Factory-trained, certified technicians. Installation, warranty work, repairs, and maintenance are handled by our own team. 

• 24/7 emergency service. Outages don't keep business hours, and neither does our service line. 

• Maintenance programs. An annual (or semi-annual, for generators that run often) service plan keeps your unit ready before you need it. 

• Financing and generator leasing. Financing is available through Synchrony for whole-house systems, and generator leasing is also available. 

Sizing: The Decision That Makes or Breaks a Standby System 

The most common mistake we see in the field is a generator sized to a budget instead of to a load. For most Maine homes, a whole-house standby generator lands between 10kW and 24kW, depending on what you need to keep running — heat, well pump, sump pump, refrigeration, and increasingly, heat pump systems. Small businesses typically start around 30kW. 

A generator that's too small will shed the loads you care about most; one that's oversized wastes money up front and fuel every time it exercises. That's why we do free on-site consultations: we look at your panel, your fuel supply, and how you actually live in the house before recommending a size. 

Fuel and Runtime: What to Expect in a Long Outage 

Standby generators connected to propane or natural gas can run for as long as the fuel holds out — which is what you want when an ice storm takes lines down for days. Portable generators are a budget-friendlier backup, but plan around their tank: typically 6 to 12 hours of runtime per fill, which means someone is going outside to refuel in the weather. 

For most Brunswick, Bath, Topsham, and Woolwich homes we install on propane, with tank sizing matched to the generator so a multi-day outage doesn't become a fuel-delivery emergency. 

Installation Done Right the First Time 

A standby generator is an electrical project as much as a mechanical one: transfer switch, dedicated circuit work, code compliance, and coordination with your fuel supplier. Our roots are in the electrical side of this work — we spent years handling the electrical hookups for the generators we installed before the company took its current name — so the wiring is never subcontracted guesswork. 

Frequently Asked Questions 

What size generator do I need for my Brunswick home? 

Most whole-home systems fall between 10kW and 24kW; businesses usually need 30kW or more. The honest answer depends on your panel and priority loads, which is exactly what a free on-site consultation determines. 

How long will my generator run during an outage? 

A standby generator on propane or natural gas runs as long as fuel is supplied. Portable units typically run 6–12 hours per tank. 

How often should a generator be serviced? 

At minimum once a year — more often if it runs frequently. Our maintenance programs handle the schedule for you.
