"GenPro installed a Home Generator for us. Andrew Spitzmueller and his team were dependable and reliable. Did what they said they would do. When they encountered roadblocks with sub-contractors and permit inspectors, they worked diligently to resolve the situation. They are honest and trustworthy people. Highly recommend them."

"A1 Plus Electrical had the best price, and the electricians and plumber did excellent work! The only problem experienced was that it took 5 to 6 weeks for A1 Plus to get the permits approved after stating that they could get the permits approved and install the generator within 2 weeks. All other companies couldn't do the work for at least 2 months or longer! I had to contact A1 Plus general manager to get things moving after several permit submissions were rejected by the city. A1 Plus mitigated this time inconvenience by installing an electrical outlet in the garage at no cost, and once the permits were approved, everything was done within 7 days. Permits were approved on Friday, and installation started on the following Tuesday, and city permit inspections were done on the following Friday! All within one week! Would I hire A1 Plus to install my generator in the future? YES!"

"My technician Brian was fantastic! He was very knowledgeable and shared that knowledge in a very easy to understand manner. He offered me suggestions for my concerns without trying to offer me products or services that were not needed. We had them upgrade our electrical panel to allow our generator to power our home. Brian not only showed us the process, he helped me to put my generator together and get started. A true professional and we will be calling him back out to install our EV Charger when the time comes. Highly recommend!!"

"Ronnie, Pam, Cindy and crew were wonderful to work with.  There are several steps to the process, given potential permits needed and coordination of service dates with Center Point Energy.  They kept me informed and walked me through the process at each step. 
I got bids from three companies.  Storm Guardian's bid was the lowest and included the most features.  It included Mobile Link, which the other two did not even mention.  Being able to remotely monitor the generator and receive alerts on my IPhone and on-line when the generator turns on/off is great.  Almost as important to me, they came through on their promise of near turn key.  The other bids had me doing a lot of the leg work with Center Point.  With Storm Guardian, I only had to make two phone calls and be home half a day to authorize Center Point's replacement of the gas meter. 
I am very pleased with Storm Guardian and can recommend them without reservation.  Great work, great people.

"I recently had a subpanel and generator interlock kit installed at my home, and I couldn’t be happier with the experience. From start to finish, they were professional in every way. The quote was accurate and fair with no surprises, and they got me on the schedule much quicker than I expected. They arrived promptly, communicated clearly throughout the process, and completed the work efficiently in a short amount of time. The installation looks great and everything works exactly as it should. I would absolutely recommend them to anyone needing electrical work done."

Generator Install questions, answered by experts

It might seem counterintuitive, but installing a generator transfer switch will save you money in the long run. While you’ll have to pay between $400 and $2,500 to have the transfer switch installed, you’ll recoup that amount later on when you don’t have to pay for expensive repairs to your appliances, devices, and electrical system that may have burned out, overloaded, or stopped working due to a sudden loss of power or an incorrect hook up of a generator to your home. 

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500–$2,000

  • Partial-Home Generators (9kW–20kW): $2,000–$6,500

  • Whole-House Generators (22kW–48kW): $5,000–$18,000

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.
