"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."

"Not only did the electricians promise to come to install the stovetop as soon as it came in, they came a few days after we first made contact to see what the work would entail and agreed to dispose of the cracked stovetop for us. They kept their promise by coming the day after the stovetop came in, worked efficiently and made sure it worked properly before leaving. My husband and I were extremely impressed with their work."

"This was to install a standby generator. The advance planning was excellent as was the quality of the work. Customer service is outstanding. Price was high, however. LaPlante was the highest of 3 bids received. Nevertheless, I selected them because of their professionalism and customer service."

Generator Install FAQs, answered by experts

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.

Potential benefits of using a natural gas generator include reducing your carbon footprint, lower likelihood of carbon monoxide exposure, budget-friendly operating costs, and low-maintenance, continuous fuel supply. Some possible drawbacks, though, include higher initial installation costs, dependency on a natural gas supply, and installation complexity. Keep in mind that pros and cons will vary based on the type and brand of natural gas generator. 

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.
