We are the experts in the field of Whole Home Generator Sales and Installation, with over 20 years of experience in the game. We provide turn-key installation by licensed professionals - 24 hour emergency service - Remote Monitoring - Long term maintenance and service by factory trained technicians.

"They initially contacted me via email ready to make a visit for the install. Said that they could do the project no problem. Then when they realized I wouldn’t be buying a generator from them, which I had TOLD them upfront, they canceled on me. That is not an acceptable way to do business. They should simply state that they only install generators that they sell and not waste my time."

"Very expensive and took two different visits by different techs and a long amount of time (3+ hours) to set up basic file sharing within a home network. This should have taken less time and one visit in my opinion."

"Mike was professional, thorough, and quickly ran a new 50 amp circuit across my entire home to the garage where he installed my Tesla charger. His quote was great, and he did not try to upsell anything to me. Another company I wanted a bid for the same thing left my house with a quote that was literally 6 times the cost. The other two quotes I received were close to double the cost because nobody else either envisioned the most direct route to my garage or just wanted to run double the wire length to charge me more. Mike is a no-nonsense and trustworthy electrician who will get your project done without any sales gimmicks."

"This company is absolutely fantastic! Tony is so professional and a really great guy. He bid me a price for some work that turned out to be much more complicated than originally thought. He did not try and increase his price and did the work for the pre-determined rate. In addition, I had a tv he was supposed to hang that was brand new in the box. When he opened it, he discovered the screen was shattered. I was able to return the tv and he is coming back out on a separate trip to hang it. He has really gone above and beyond. I cannot recommend him more highly."

FAQs for generator installation projects in Creve Coeur, MO

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
