When a storm takes the power out, a home standby generator keeps your heat, water, and refrigerator running without you lifting a finger. Mid Maine Generator has been installing whole-home Kohler standby generators for Maine families since 1991, and we are the largest Kohler dealer in the Northeast.
What Is a Home Standby Generator?
A standby home generator is a permanent power solution for your house. It is installed outside, much like an air conditioning unit, and it starts automatically when the power goes out, whether you are home or away. Within about ten seconds it picks up your heat, air conditioning, sump pump, well pump, and major appliances like the refrigerator and oven, all at the same time. It runs on propane or natural gas, so there is no fuel to haul and no extension cords to run in the dark.

Why Maine Homeowners Choose Kohler
Every Kohler generator is quality-tested from start to finish. Kohler's engineering team runs hundreds of performance tests during the design process, and each unit is put through its paces again before it leaves the factory. Inside every Kohler generator is a commercial-grade engine built to handle heavy workloads over many years, the same class of engine you would find in heavy construction equipment.
The 14kW and 20kW models carry Kohler's 5-year, 2,000-hour protection along with a corrosion-proof composite enclosure built to stand up to Maine's coastal salt air and inland winters. An optional 10-year warranty is also available.

What Size Generator Do I Need?
You do not have to work this out on your own. Our team sizes your generator around how you actually use your home: your electrical panel, your fuel source, the well and septic pumps, and which circuits you want covered during an outage. We come to you, walk the property, and recommend the right unit rather than selling you more generator than you need.
How Your Generator Gets Installed
A standby generator system involves a lot of moving parts, and we handle all of them for you:
- Decide on your budget and how much of the house you want powered.
- Call the office and we will set up a site visit to determine the generator size and equipment you need.
- Once you approve the quote, we schedule your installation.
- We install the generator, pad, and transfer switch, with all wiring and propane work completed in one day.
- Our Kohler certified technicians perform the warranty start-up and submit the warranty paperwork for you.
Because we are licensed for both the electrical and the propane side, the whole job stays with one crew. There is no waiting on a separate gas contractor before your generator can run.
Service After the Sale
A generator is only as reliable as the team behind it. Nearly 8,000 Maine households and businesses are on an annual service agreement with us, which brings priority scheduling, 24/365 emergency support, and member pricing. We service what we install, and we service Kohler, Generac, and Briggs units that were purchased somewhere else.
Every generator installed by Mid Maine Generator comes with a discounted annual maintenance rate — ask our team for details when we quote your system.
