"Would not recommend Mr. Electric; they will try to scam and overcharge you. My girlfriend called them for a fried breaker and the technician tried to upsell and convince us to replace the ENTIRE electrical panel and additional unnecessary fixes for over $14,000. We called a different company for a second opinion and they assured us that the panel did not need a complete replacement to get things up and running, and only recommended a few replacements for safety measures. We were able to get the initial situation fixed the same day through the second company, all covered under the other companies ‘free second opinion promotion’ they were running. The thing is, we would have been willing to get some of the recommended safety work done, and still plan on doing it with a different company, but the Mr.Electric tech representative was pushy and dishonest, and tried to get us to finance a way more expensive fix than needed. I don’t frequently leave reviews, and I know it’s nearly impossible these days to find a company that isn’t trying to upsell or push you into something, but this is one company that should be avoided at all costs."

"My circuit breaker box blew an 80 amp circuit and blew the main breaker outside. Mr. Sparky came and replaced both circuit breaker boxes, one main breaker to the house and re-ran the line from the main breaker to the circuit breaker box, correcting an incorrectly installed line. They made sure that everything they did was up to code and guaranteed the work for 30 years. They had to replace all my GIFI outlets and add additional hard wired smoke detectors. It was not an inexpensive job, but I feel secure that they did a great job and were careful and explained everything to me as they went. I would hire them again."

"We replaced the original roof on our house. I expressed my concerns about re-installation of the lightening rods to my roofer. We have had at least three direct hits since they were originally installed in 2013. My roofer called William who was very helpful. William offered to come out an make sure everything was 100% after re-installation. He came the day after I called and I'm glad he did. While the reinstall was the best he had seen (his words) there were issues after 5 year and 3 strikes that needed addressed. He fixed those and now I have a new roof and I am certain the lightening rods will work as intended. Highly recommend this company."

FAQs for generator installation projects in Signal Mountain, TN

Installing a whole-house generator costs about $5,000 on average. Prices range from $1,550 to $8,500, depending on size, brand, fuel type, and assembly. The size of your whole-house generator is the most significant cost factor, with large homes with high energy demands costing the most to power. Types of whole-home generators include:

  • Portable generators with 1kW–7.5kW capacity: $500–$2,000

  • Partial generators with 9kW–20kW capacity: $2,000–$6,300

  • Whole-house generators with 22kW–48kW: $5,000–$18,000

When maintained properly, a whole-house generator can last up to 20 years. Costs to maintain and repair generators vary by location and type of generator, but you can expect to pay about $150 to $300 per year for annual generator maintenance checks. An experienced generator service technician will inspect your generator’s engine filter, starting mechanism, fuel, lubrication, and coolant levels to keep your generator in good working condition for as long as possible.

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

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 value of installing a whole-house generator is that your home has guaranteed power, even if the power grid in your area is down. Whether a whole-house generator is worth installing in your home depends on how often you use it, your home’s location, and your lifestyle. For example, installing a whole-house generator is likely worth it if you:

  • Experience frequent or prolonged power outages

  • Work from home

  • Store a lot of cold food

  • Have a sump pump

  • Have a pump for well water

  • Use electronic medical devices

  • Live in a climate requiring heating or cooling
