"I paid for a maintenance contract w these people then called them for repair work. They misdiagnosed the problem three times then left the battery and parts of my very expensive standby generator out on the ground and in the weather. Then they admitted they were not even authorized to do warranty work on a cooler generator. Now with my maintenance contract, and my money, they have not contracted out the work, will not return my calls, my texts or my emails"

"SSGE acted like a teenager wrt aftersale service. The first time I called SSGE was when then was an alarm on the system, ( a year after install) and they refused service!!! The reason per SSGE was that there was dispute during install. During the sales process, SSGE had told me that HOA approval was NOT needed. Right after installation, the HOA wanted to remove the generator, and it took me 2 weeks to sort out the issue. I paid SSGE the second half of the payment in full only after the dispute with HOA was settled in about 2 weeks.Is that a good enogh reason to not provide service?? I had to call Generac's head-quarters and they helped me trouble shoot the alarm on my system."

"I've had EV charger installed 2 other times prior to using Santiban Services Group (different locations), but never once experienced this level of customer service that Gabe provided. Although, it was my most expensive installation (which I can't blame them due to the odd place my builder placed the breaker box), but the price was quoted fairly and justified. Gabe went above and beyond such as stopping by my house, taking photos, drawing where he was going to do the wiring, and walking me through his findings. On top of that, he even did a load calculation which advised me to install a load management system so my breaker box wouldn't overload. This alone said he's a very thorough and dedicated person. I appreciate that so much because no other electricians were doing that and kept telling me that "it will be fine". Being a first time homeowner, I would like to protect my house to the best of my ability, so saying "it will be fine" doesn’t really give me a peace of mind. So thank you Gabe!!!! For helping me to ensure my breaker box would be fine with the new addition. I hope to continue to use your service in the future 🙏🏻 😊 also, thank you for going the extra mile to vacuum the work area after you guys were done, it was a very nice gesture 🤗"

Generator installations FAQs
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
