"Fitch Electric installed a stand by generator for my home. They were able to get a generator for me within a few weeks. Generac is running 20 weeks behind so I was happy to be able to have it installed much sooner. The process was smooth and professional. They were available to answer any and all questions that I had, so I was very pleased with their service."

"I recently had the pleasure of working with Brian from Hamilton Electric for a hot tub installation, and I couldn’t be more impressed with the experience. From start to finish, Brian demonstrated the highest level of professionalism, expertise, and attention to detail. The entire installation was handled seamlessly, with meticulous planning and execution to ensure everything was up to code and functioning perfectly. Brian was incredibly knowledgeable, answering all my questions with clarity and confidence. His workmanship was outstanding, and he took the time to ensure a clean and safe setup. Beyond the exceptional quality of work, the pricing was very reasonable, offering great value for the level of service provided. It’s rare to find an electrician who combines technical expertise with such professionalism and customer-focused service. I highly recommend Hamilton Electric for any electrical work—especially for specialized projects like hot tub installations."

"Joe is hard working, diligent, and honest. I hired him 1) to put up an antenna for local tv service and 2) to fix poor wifi signals. TV was converted from cable rapidly using leftover wires. Saving $ not paying for cable and streaming off wifi. Great signal strength! WiFi was harder. He worked with ATT to determine my new iMac was sucking signals. He installed a more powerful router that solved wifi issues when iMac is off. Now I have to work with Apple to figure out how to manage the computer searching. I would not hesitate to call Joe back again. He is an excellent technician and a fine person. He is pretty busy, so sometimes it takes a few days before he can come out, but he is worth the wait."

"Did a great job, even corrected some code violations that were present when we moved in. Installed multiple 110v, 230v single phase, 230v 3 phase and 480v 3phase circuits, wired a paint booth, Tumbler unit, overhead crane systems, and even did some repairs on a complicated piece of machinery that wasn’t working. Great guys work hard no excuses. They get the job done plain and simple. I had used them twice because they were that reliable."

Generator Install questions, answered by experts

Here’s what you can run with different wattages and types of generators:

Portable generator:

  • 2,000 watts can handle a large appliance like a freezer or refrigerator, plus a few smaller items like phones or computer chargers. 

  • 4,000 watts will keep two large appliances operating and a few smaller devices.

  • 8,000 watts should power most essential appliances and other devices, including a sump pump, well pump, or your dishwasher.

Partial to whole-house generator:

  • 20,000 watts and above will make it seem like your home’s power is still on.

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

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.

Yes, in most municipalities, you will need a permit to install a permanent home generator, including emergency backup, partial-home, and whole-home models. Because these installations involve significant alterations to your home's electrical system and produce exhaust fumes, local governments often require a permit or inspection for safety purposes. A generator permit typically costs between $50 and $250, depending on your location. Your electrician or certified installer can usually handle the permitting process for you, but you will be responsible for the cost. It's a good practice to confirm with your installer that they will pull all necessary permits before work begins.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.
