What a Power Outage Actually Costs You
Food Spoilage
A fridge and freezer full of groceries goes bad in about 4 hours without power. That's real money down the drain every outage.
Medical Equipment
CPAP machines, oxygen concentrators, and refrigerated medication can't wait for the power company. An outage becomes a health risk.
Home Office Downtime
No power means no internet, no video calls, no work. A two-day outage can cost you more than a generator does.
Heat & Humidity Build-Up
No AC in Houston's heat and humidity turns your home into a sauna within hours, and puts kids, pets, and elderly family members at risk.

Houston's Most Renowned Generator Company
"We received very good customer service from the company, from sales to service and installation. Highly recommended. The technician who came out to do the Silver service maintenance for our Kohler generator also took me through how the homeowner maintenance should be completed (I recorded it for the future for when I forget, inevitably, what he said to do, LOL!). Very polite young man named Chris. Great job!"
