"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

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.

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.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

Generators are usually sized by running watts and starting watts. Ideally, you’ll want a generator that can offer both the necessary running watts and starting watts for everything you need to power without going beyond 90% of its capacity. Calculate your home’s electrical load based on the breakers in your home or adding up the appliance and lighting needs of connected rooms.

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.
