"SeaTown installed a standby generator. They provided us with a wide range of options, and were very good about advising us of the ramifications and external costs associated with each. They coordinated permits, locates and utility requirements, making the process easy for us. The installers were courteous, respectful of our property, and did a fine job. We are now using them to install AC."

"I had such a great experience with the team that rewired my house! They installed new outlets and lights, plus this amazing 12 AWG wire that really helps prevent breakers from tripping. I couldn't recommend them more for anyone needing electrical work!"

"Dedicated electrical services was very professional, from the first phone call to get an estimate to completing the job. I needed six can lights changed from 'Peg' light bulbs to LEDs. The electricians that came to my home listened to what I had to say about the issue with the peg lights and provided options for a solution. During the installation of new light fixtures, that have a brightness setting, they checked after installing the first one to see if the light setting was okay before moving on with the rest. For the first time in a few years I finally have decent lighting in my kitchen. I no longer feel like I live in a cave. I will definitely be having Dedicated Electric Services come back and change out the remaining 'peg' lights in my home."

"All technicians and the business owners are professional, knowledgeable and friendly. All were easy to talk to and helpful when I asked questions about what I should expect as well as what to do if I needed assistance with service and other related things. The company was upfront about costs and what to expect when/if main power goes off and what happens when the generator kicks in/off. I highly recommend First Choice Electrical."

Generator Install questions, answered by experts

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.

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 power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

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.

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.
