"Hank and Ray did a great job updating some wiring as well as installing lights and sockets for a bath/bedroom renovation in our farmhouse in mid coast Maine. They responded quickly, were on time when they said they would arrive, work was professional, and pricing very reasonable for two days work. It was a welcome response in working with someone “off peninsula” who actually takes customer service and responsiveness seriously. Will definitely use them again!"

"Generators of Maine just completed the installation of a 14kw generator with parallel transfer switches, to protect 2 separate metered panels at a rental property that I own. I didn't even know that this was possible, until Doug Sawyer suggested it. The incremental cost of protecting the additional panel with the parallel transfer switch arrangement was a fraction the cost of an additional generator and transfer switch. Throughout the job, Doug and his crew were awesome. I am a terrible snoop who enjoys technology, so I hung around just watching and learning. They didn't seem to mind my presence and were friendly and informative through out the install. Every aspect of the job was 100% top-notch. Doug also managed to under bid his nearest competitor on every component and aspect of the job, including the annual maintenance contract, which I deemed to be worth the $$$. I highly recommend Generators of Maine."

"Mike installed a back up generator switch and accompanying outdoor twist-lock connection. He was extremely prompt when returning calls and made his scheduled appointments. Mike is very personable and performs quality work. I will use him again when the need arises and would not hesitate to recommend him to anyone."

Generator Install questions, answered by experts

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.
