"Storm Guardian is a small family owned company. Of the three companies from which we obtained estimates I was most impressed with this company. The initial brochure with which I was presented when I  received the estimate was the most complete and informative about the company and the product.
Everyone was helpful. Myra and Cindy in the office were always very cordial and helpful in scheduling and giving me information. Example:Theywere very helpful in getting through the complexities of arranging meter pulls with the electric companies.The men that came for the installation were always on time and easy to work with (we had "mixed up" wiring in an old house). I was very satisfied with the whole process. It was a job well done.

"I recently hired an Chau dang electric to upgrade my breaker panel, replace breakers, and install an additional panel for a generator. He showed up on time, was very professional, and explained everything clearly before starting the work. The installation was done clean and organized, and he made sure everything was up to code. I really appreciated his attention to detail and the quality of his work. Overall, I’m very satisfied with the service and would definitely recommend him to anyone needing electrical work."

"They did an excellent job! I called because we had our porch light go out. Sean came out for a quote, but then he found other electrical issues (not up to code) in our house and a couple of other issues. We had some issues with covid scheduling but they did a good job of splitting the job and performed great, very satisfied with the prices also!"

"Within minutes after submitting an inquiry, Seamus contacted me to find out specifics of my project and although he provided an estimate, he was receptive to coming out for a site visit before I committed. Edward came for the preliminary site visit and afterwards, I accepted their proposal. Cliff, the installer, communicated with me with scheduling and was very professional and easy deal with. Edward performed an inspection after install to make sure everything was done properly. The people representing this company seem very knowledgeable about their work and is backed up by generations of experience."

FAQs for generator install projects in Wallis, TX

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
