"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.

"Donnie was a pleasure to work with on the phone. After describing what was required to install a Ring Floodlight, Donnie was able to provide a quote and time limit to perform the installation including some custom wiring. Jeff did the installation in the time frame quoted and the price was more reasonable than all other quotes received. I highly recommend them!"

Generator Install questions, answered by experts

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

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.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.
