"Chris and his assistant did an excellent job of explaining the situation and options for repairing or replacing our hot water heater. In the end we chose to replace it and they were able to secure a new unit and install it within 3 hours. Would definitely recommend Chris and Tri-County Services and will use them again if another situation arises."

"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

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

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.

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.
