"10 yr old Generac GP6500E wouldn’t start. Called around and many want to upsell to permanent. Found Franks and what a delight. Honest, down to earth, affordable for senior. Showed up on time. Changed oil, spark plug. Pulled carburetor and found it dirty and fouled. Got used one from his shop(same day) and installed. Gen started right up on one or two pulls. Battery was dead but showed us how to replace. Highly recommend Frank’s Generator."

"I have found my forever electricians (at least while I live in the New Haven area)! From start to finish my experience with Power Forward was an absolute pleasure. Company owner, Ian, was responsive, punctual, and incredibly informative when it came to walking me through the details of the scope of work I was requesting, and was thoroughly transparent and fairly priced when it came to his estimate. Once we accepted the quote, scheduling with Morgan was easy and efficient, and Chris arrived onsite within a day of me accepting the estimate. Chris was a consummate professional, a super clean worker when it came to caring for our house and the cleanliness of his cable paths, and was truly dedicated to doing the job â the right wayâ not just the easy and cheap way. He took his time and planned his cable runs and circuiting carefully to ensure both minimal cutting into our walls and convenient receptacle placement. Once he was finished, he took care to clean every area heâ d worked in and probably left some of the rooms cleaner than when he arrived! I would recommend Ian and Power Forward to anyone who appreciates work that is done with care, safe, and efficient. I think you get what you pay for when it comes to hiring trade professionals, and electricity is not something you want to cut corners with: hire Ian and his team, and have it done right and safe the first time."

Generator Install FAQs, answered by experts

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.

With proper maintenance, a whole-house generator can last between 20 and 40 years. The specific lifespan depends on how often and for how long the generator is used, and some models may have their life expectancy rated in hours of operation. To maximize its lifespan, expect to spend around $150 to $300 per year for annual maintenance checks from a qualified technician. During these checks, a technician will inspect the engine filter, starting mechanism, fuel, lubrication, and coolant levels. Consulting your installer and choosing a low-impact fuel like natural gas or diesel can also help ensure your generator lasts as long as possible.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency.
