"Hiring Fleming's Electrical Service to install a sub panel and rewire my garage was the best thing I could have done! Brandon and Billy were fantastic! Their work was the best and their customer service first rate. With Fleming you get highly capable electricians and professionals that care about what they do. Pricing, communications , and follow-up was better than I could have expected. We're already talking about another job to install recessed lightning."

"Triple J Electric provided outstanding service in three areas. They did an excellent job installing 4 ceiling fans and remotes. Made smart decisions in programing fan remotes, communicated with me throughout the process, and took the empty ceiling fan boxes to dispose them so I wouldn't have to. In addition, ensured there was no debris left from fan installation. I highly recommend Triple J Electric for your future electric work"

"I would like to thank Crest Electric and their team for the work they did at my new home. We recently purchased a house in DE, and being new to the area, it was a relief to find a fair and reliable contractor who takes pride in their work. I needed their help with installing recess lighting, raising the electrical outlets, mounting TVs with TV mounts, installing chandeliers, and handling the installation of doorbells, cameras, and floodlights. It was such a relief to have Crest Electric manage this huge project, and they offered a reasonable price without making me feel like I was being ripped off. I highly recommend Crest Electric for their attention to detail and their willingness to make adjustments to ensure that everything is perfect in the eyes of their clients. This is something that a lot of contractors take for granted, but Crest Electric truly understands the importance of meeting their client's needs and preferences. -Michael"

"I needed a 15A circuit installed with receptacles and a switch and rough-in for an overhead fan/light. Mike arrived with an assistant and was on time (actually a few minutes early). After a quick conversation to go over the job again, they jumped right into the job. The price was reasonable and the work was done exactly as discussed and within a short amount of time. They were professional, conscientious, and cleaned up the work area before they left. I would hire them again in a heartbeat AND would recommend them to others. ...as a matter of fact, already have. Thanks again Mike!!!"

"William Burden is the third generation owner of WBLightningRods and his company has been in business since 1950. He is very courteous, professional, was on time, and has a very good crew. William was present for the entire installation. We chose the copper system. We are glad for the peace of mind a lightning rod system will provide."

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.
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 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
