"The initial contact was very courteous and helpful. They were able to give me an estimate by phone, which was reasonable. When I wanted to book, they got me scheduled quickly. And the electrician who came to do the installation was very nice and did a great job. Thank you."

"Very responsive and professional on our first visit .Technician Charles Monday gets a five star review based on his thoroughness and professionalism .We have two old AC units that are not functioning well as they were installed when we moved to the house 21 years ago .Mr Monday came on time and spent hours in the attic taking care of a leak and cleaning the furnace and filters and motor ,and we are grateful .He explained each step and consulted with me and took photos to document the problems encountered .Whereas we are contemplating replacement due to the age ,we feel we got our problem taken care of until the nest step which is a replacement of our units .I was impressed with his knowledge base and how he took so much time in making sure the AC was in running condition when he left ."

"Starting with the sales process, Nate was informative and great. Could've sold me a more expensive replacement system, but instead identifies how my current system cod be retrofitted with a heat pump. That sold me on G&S right there. Everything from the initial install review, the office staff working with my lender, to Izaak and the install and electrical teams, was punctual, informative and professional. I've had several bad experiences with other contractors, but I would confidently recommend G&S for any job and plan to use them again for a generator switch install. Good people with a good business. Thank you G&S!"

"They showed up exactly when they said they would(very important). They very courteous and knowledgeable with all aspects of work to be done. You would trust them in your house with whatever electrical work you need! Polite and explains everything while doing the work. It was like going to school, but the teacher does all the work. Also did some changes to original work and they accommodated that very easily. Have already referred them to other people in my office who need electrical work and wouldn't hesitate to refer Jason and his partner to anyone in need of electrical work."

Generator Install FAQs, answered by experts

While diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.

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. 

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.
