"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.

"This is what I found while checking the oil. I contacted Chris at Power up to look at the issue. An appointment was set up in a timely manner and the tech that came out was excellent. He found the leak on one of the oil cooler hoses. He removed the factory clamp and replaced it with a new clamp. After several weeks there hasn't been any oil in the base of the generator. I have also had Power up tech come out and adjust the valves at the recommended interval. The generator sounded much better after the valves were adjusted."

Generator Install FAQs, answered by experts

The amount of time a standby generator can run continuously is around 3,000 hours on average. However, standby generators can generally run indefinitely as long as they have a continuous fuel supply. Generators hooked up to a home’s natural gas supply are the best option for extended usage, as these won’t rely on a finite fuel supply based on how much you have in storage. Generators running on liquid propane or diesel won’t last as long, as these require fuel storage and regular refueling to stay running.

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.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

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.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.
