"Great service and both Brandon and his coworker were professional, prompt and courteous. I rated customer 4.5 only because for the generator install he had forgotten to tell me I would need gas lines run, which increased the price 450$."

"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 am one very Satisfied customer! Chris and Debra of Galloway Electrical arrived early, took a quick look at what needed to be done, provided a very reasonable price that I accepted and grabbed their tools and went to work. They were very thorough, kept us informed of the progress, explained everything and even provided recommendations for future upgrades. Chris and Debra were very professional, courteous, respectful of our property and a pleasure to talk to. My wife and I were very happy with the final product and will definitely hire Galloway Electrical for any future electrical needs! A big "Thank You" to both Chris and Debra!!!"

"Installation of my ceiling fan was tougher than expected due to the replacement of a fan mounted on a 20' ceiling. Dale, and his helper, D'Jere, did an excellent job replacing my old ceiling fan with a new one I purchased. Installation required removing the old fan and its 8' droprod, and installing the new fan with a different droprod. The job required assembling a two-tier scaffold with the use of an additional stepladder to get to the ceiling. Dale and his partner worked meticulously to get the job done, and the result was perfection. After the installation was completed, and the scaffolding was removed, Dale and his partner walked around the living room picking up any wire insulation clippings and other small pieces left over on the floor. They left the place pretty much spotless. Dale and his partner did a fantastic job, and I would definitely hire them again."

"Zach promptly looked at the project, asked pertinent questions, offered suggestions and provided a quick quote. Once quote was accepted an install date was agreed on. Zach performed work on time with a minor adjustment to the quote based on a change I requested. He was a pleasure to work with and quickly responded to emails and texts. Definitely recommend and would use for any future projects."

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
