"DC = Dale Castro, a top-shelf electrician who services my Generac generator, and repaired a faulty outside electric box/switch. Extremely neat wherever he is working, cleans everything, and to boot: he is a super-charged great person. Consider yourself lucky when he is on premise."

"We hired Paul knowing nothing of him except he was on Angie’s List. He and Brandon didn’t disappoint and I can’t say enough great things about the two of them and their work. They were very reliable and were so easy to have in the house. They laid down plastic over all carpeted areas and cleaned up every evening. Extremely professional in both their work and business and were very fair. They were fine with making changes, The two full bathrooms were gutted and the 1/2 bath a new vanity installed with new toilet. I couldn’t be happier with the end result and I would absolutely hire them again. Linda-Aurora"

"Blake returned my call that day for work that included installation of lights and outlets in basement, installation of a dedicated outlet in garage and troubleshooting some other issues. 4 days later the work started and after some initial changes a majority of the work was completed. Finished the job the following week with a half day of work. Called with an issue regarding a GFI switch. They were out the next day and determined that the issue was with the Christmas lights not the electrical wiring. Nick was polite, punctual, and cleaned up after himself. Would definitely use again and highly recommend."

"The entire process from Quote to Installation was very thorough and seamless. Ryan went over the installation process in detail and answered all questions. The install went great as well. He was very considerate. He made sure that he wore protective feet coverings as well as a mask. He went over all the work that he performed and cleaned up all debris from the job. I really appreciate the up front pricing that is thoroughly outlined in his work manual. I would definitely use this company again."

"Blue Star did a stellar job and would hire again. We had a bad storm to which a branch fell on our electrical wiring disconnecting the power from the home. Hank and his team made our situation a top priority to get us back up an running, even in the poor weather. In addition, I requested a certain installation with the uncertainty of it being completed...Hank came through on that too! Blue Star did a great job explaining and walking us through the job to understand, quoted a good price, and completed stellar work to finish the job! Thanks, Blue Star!"
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
