"Sebastian was top rate. On time, diagnosed issue, checked outlets & breakers. He had the right parts in the truck and was able to install new breakers (replacing the prone to fail AFI/GFI combo). Refrigerator is safe and the dishwasher/disposal is working again. Very happy with the great service and the on-the-job explanations that he had to help me be an educated customer. I will definitely use Sebastian on my coming up home improvement projects."

"Josh did a great job with the stairs! He was very timely in being able to get us a quote and order materials. Communicated very well throughout the process and able to get things done efficiently. After installing the deck he stained the staircase and it matched the original deck very well. He cleaned up after himself and all went great! Thanks! Will consider him again in the future when we need something done"

"Sean did a good job and worked efficiently. He was able to do all the tasks we requested. I'm satisfied with his work. He did our job on a Saturday and I was very happy he went out of his way to work us into the schedule. I would hire him again, no question. The only disappointment was that he didn't clean up afterward as well as I thought would be done. For example, where metal siding had to be cut to install new fixtures, there were still pieces of the sharp metal lying around (larger than an inch square)."

"I was introduced to Sacry through a third party. But I have now found an electrician for life! They showed up with little notice, analyzed the scope of what to be done, and made some recommendations. These recommendations were not so they could charge more, but rather so the job could be completed safely, and look professional. Sacry Electric went out of there way to make sure I was satisfied. I wish more companies had the same values as Sacry, putting the customers wants, needs, AND budget as their only priorities! Thanks again Sacry! I will be calling again soon!"

"He was fine. It was a simple problem with a short, and he showed me how to fix it but didnâ t do the work himself. Thatâ s okay, depending on how much heâ s charging. If he chose not to charge me, then thatâ s wonderful!"
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
