"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.

Generator Install FAQs, answered by experts

If you’re wondering if you can use your electric vehicle as a backup battery, it depends on whether your EV is compatible with bidirectional charging. This technology allows energy to flow both ways, enabling vehicle-to-home (V2H) backup power, vehicle-to-load (V2L) for appliances and camping, and vehicle-to-grid (V2G) to support the power grid. Compatible EVs convert stored DC energy into usable AC power, helping reduce energy costs and enhance grid stability while providing emergency backup power.

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

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 power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

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.
