"Sweetwater Electric installed my Generac whole house generator. Part way through the installation, we discovered a problem with the landscaping and placement of the generator. Sweetwater was patient while we worked out the issue and resumed work the day after the landscaper left. Alan and Thomas worked well together as a team and finished the installation without a problem. I would highly recommend them for your Generac, or general electrical, work. They are conscientious, hardworking, amenable and clean up after the job is complete. What more could you ask for?"

"Charles and Joyce from Homestead were great to work with. From the time they came out to quote our generator, placement, installation through final inspections. Charles has great attention to detail. They treated our home as if it was theirs. Joyce helped with all the documentation and warranty process. Great people to work with."

"We were very pleased with the quality and service we received. We hired Kevin to wire our new construction house project in 2018. We later had him back to install a 12KW solar panel system and an EV charging station in 2021. I highly recommend Kwaske Electric."

"Writer is a true professional and electrical guru. He arrived within the allotted time frame, got right to work and quickly identified the problem. He even welcomed me to watch him while he worked as he explained the intricacies of the electrical outlet (which was a GFCI multi-branched oulet, connected to other garage and bathroom outlets). It was clear he knew what he was doing. I would recommend him for any electrical problem or fresh installation, and plan to hire him in the future for other electrical projects I have around my house."

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
