Tri-State Water, Power & Air has been providing high-quality backup generators since 1992, helping local homeowners find reliable power solutions tailored to their needs. Our experienced team will guide you through selecting the right standby generator, ensuring it provides dependable power for your home.

Choosing the Right Home Generator for Your Needs

At Tri-State Water, Power & Air, we offer an extensive selection of home generators from trusted brands like KOHLER and Generac.

Hassle-Free Power Thanks to Automatic Activation

These systems connect directly to your home’s fuel source, providing continuous power without the need for refueling. This seamless integration means that when the power goes out, your generator will activate automatically, keeping your essential appliances, HVAC system, and security features operational.

A Reliable Home Generator Option in St. Louis

Tri-State Water, Power & Air provides professional installation and ongoing support, so you can count on your generator to keep your home powered and protected during unexpected outages.

Determining the Ideal Generator Size

Choosing the right standby generator is one of the most important parts of the project. A generator that’s too small may struggle when several appliances start at the same time, while an oversized unit can cost more than necessary. At Tri-State Water, Power & Air, we take the time to recommend a system that fits your home’s electrical needs and your budget.

We start by learning what you want to keep running during an outage. Some families only want the essentials, such as the refrigerator, furnace, and a few lights. Others want whole-home coverage that keeps air conditioning, kitchen appliances, entertainment systems, home offices, and other everyday conveniences operating without interruption.

From there, we evaluate your home’s electrical system and calculate the total running wattage for the circuits and equipment you want powered. We also account for the extra start-up power that larger appliances require. Air conditioners, well pumps, refrigerators, and similar equipment need a temporary surge of electricity when they first turn on. If that additional demand isn’t considered, your generator may not perform the way you expect during an outage.

By carefully reviewing your home’s electrical load and future needs, we can recommend a standby generator that provides dependable performance today while leaving room for changes down the road.

We’re Generator Installation Experts

A standby generator is much more than a piece of equipment sitting outside your home. It becomes part of your electrical system and fuel supply, which is why professional installation matters.

Every generator installation we perform in St. Louis begins with evaluating the best location for the unit. We consider manufacturer spacing requirements, local building codes, ventilation, accessibility for maintenance, and protection from flooding or other site concerns. Once the location is selected, we prepare the foundation, install the generator, connect the natural gas or propane fuel source, and integrate the automatic transfer switch with your home’s electrical panel.

The transfer switch plays a critical role by detecting a power outage and automatically switching your home to generator power within seconds. When utility service returns, it safely transfers power back without requiring you to go outside or manually start the generator.

At Tri-State Water, Power & Air, our experienced technicians test the entire system before the project is complete. We verify that the generator starts properly, transfers power correctly, and operates as designed. Professional installation helps reduce the risk of electrical problems, fuel leaks, code violations, and equipment damage while giving you confidence that your backup power system will be ready when you need it most.

Home Generator FAQs

How long can a standby generator run?

Most standby generators can operate for extended periods as long as they have a steady fuel supply from a natural gas line or a properly sized propane tank. The exact runtime depends on the generator’s size, the fuel source, and the amount of electricity your home is using.

How often should my generator be serviced?

Routine maintenance is recommended at least once a year or according to the manufacturer’s guidelines. Regular service helps keep the engine, battery, filters, and other components in good working condition so your generator is ready when it’s needed.
