Have a Top-of-the-Line Natural Gas Generator Installed at Your Home in St. Louis, MO

Natural Gas Generator St. Louis

Power failures in St. Louis, Missouri, are never predictable, and when one occurs, it’s impossible to know how long it’ll last. It’s best to have a plan in place to ensure you can maintain power. At Tri-State Water, Power, & Air, we’re backup power specialists who can install a premium natural gas generator capable of powering everything from a few lights and your HVAC system to your entire home.


Tri-State Generators are built to last and feature a rust-resistant outer casing that can withstand harsh elements year after year. You can expect the same build quality on the inside. Our generators automatically perform a self-diagnostic check each week to ensure they are ready to supply power when you need it most. And, when an outage does occur, you’ll experience only the briefest interruption to your power supply, as an automatic transfer switch will turn the generator on immediately.

Because we specialize in natural gas generator installation, Tri-State’s team has installed countless systems over the years, giving us an unrivaled level of experience and expertise. We’re so confident in the quality of our products and the skill of our installers that we back our products with a 10-year warranty – double the industry standard.

Contact Tri-State Water, Power, & Air today to learn more about the benefits of having us install a natural gas generator at your home in St. Louis, MO.

These folks are great! Had two whole house generators installed and both are flawless. Customer support is top notch. Highly recommend.

Tri State Water Power and Air just installed three whole house water systems for my family. The representative that came to my home was very courteous, professional, and not pushy.
