"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

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.
