"On Thursday, the technician (David) came to my house to look at two projects: replacing a leaking electric water heater, and installing a new gas line (in my crawlspace) to my masonry fireplace so I can convert from wood to gas logs. He explained my options, and quoted prices for these options. I asked if he could do the work on the upcoming Saturday, and he scheduled this before he left! I ordered the gas tankless water heater and the gas line to my fireplace. By the way, I had 3 different plumbers look at this work, WyattWorks had the lowest prices. On Saturday David and Alex arrived early in the morning and worked past 6:30 PM to complete both jobs. The installations were great. Everything to code, and with neat, high quality workmanship and thoroughly tested. They cleaned up the work areas and hauled away my old water heater. In other words, a typical WyattWorks job."

"Very well. The All Electric Inc. electrician, Ashton did an excellent job in a reasonable amount of time. He was knowledgeable and neat as well as cleaning the area when the project was finished. I would consider All Electric and definitely Ashton for any future projects. Thank you, Henry Miller/Campbell, Ohio"

"Mr.Electic and Ryan, as well as the electrician, were all amazing. My electric panel burned out at night. I called them at 10pm and they had a representative at my house the following morning. They're quote was within market rates with a bit of an expected mark-up for urgency. It was definitely reasonably priced, especially since i couldn't find anyone else able to do the job right away. Long story short, the electrician was at my house the very next day after the quote and did an AMAZING job installing a larger panel. They needed to cut the wall to make more space and did it in a way that is practically invisible from the outside. You really cannot go wrong with this provider."

Generator Install questions, answered by experts

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.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home

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.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.
