10 Best Natural Gas Generators 2025 in the United States

The Generac Guardian 26kW Home Standby Generator is designed to provide reliable whole-house power backup, delivering a strong 26,000 watts of clean and stable electricity suitable for most residential needs. It runs on natural gas or propane, which are cleaner fuels compared to gasoline, and the G-Force engine is built for durability and lower maintenance. The generator features an electronic ignition for easy automatic starting during outages and includes a 200 Amp transfer switch for seamless power transfer to your home.

In terms of noise, it is described as “super quiet” with a fully enclosed aluminum casing, helping it blend into outdoor environments without being too loud. At 518 pounds and fairly large dimensions, it is not portable and intended for fixed outdoor installation. The generator is designed for standby use during power outages rather than continuous operation.

Maintenance is simplified by the G-Force engine’s heavy-use capability and lower upkeep needs. WiFi connectivity allows remote monitoring of performance and status alerts. Installation requires a professional electrician due to complexity and safety considerations. With a 5-year warranty, this generator is a reliable, quiet, and relatively low-maintenance option for homeowners seeking automatic and seamless whole-house power protection, though it is less suitable for those needing portability or extended continuous run times.

The Generac 7210 24kW Air Cooled Guardian Series is a robust natural gas generator ideal for residential use, particularly during power outages. One of its standout features is the comprehensive power output of 24,000 watts, which can effectively keep an entire home running. The included 200-amp transfer switch ensures seamless integration with your home’s electrical system, providing peace of mind during emergencies.

A key strength of this generator is its smart controls, which include Wi-Fi connectivity for remote monitoring. Users can check the generator's performance and receive maintenance alerts via the Mobile Link app, making it simple to ensure everything is running smoothly even when you're not home. Additionally, the True Power Technology guarantees clean power with very low harmonic distortion, which is crucial for sensitive electronics.

In terms of installation and use, Generac recommends professional setup by a licensed electrician, which may be a drawback for DIY enthusiasts. The generator weighs 455 pounds, making it less portable than smaller models, but it is designed for permanent outdoor installation, which can be an advantage in terms of durability and functionality. The 5-year limited warranty offers added assurance, and while some users may find the noise level during operation to be higher than expected, this is a common trade-off for powerful generators. The Generac 7210 is a strong contender in the natural gas generator category, ideal for homeowners seeking reliable backup power with smart features. Its weight and installation needs may not suit everyone, and those looking for portable options should consider alternatives.

The DuroMax XP13000HXT is a powerful and versatile natural gas generator that stands out with its 13,000 watts of power, making it suitable for both residential and commercial use during power outages. One of its key strengths is the tri-fuel capability, allowing you to use gasoline, propane, or natural gas, providing flexibility and convenience depending on availability and cost of fuel. The powerful 500cc OHV engine supports this high wattage, ensuring reliable performance. It includes a CO Alert feature that adds a layer of safety by protecting against harmful fumes, which is crucial for indoor use or in enclosed spaces.

The generator is relatively easy to start with both push-button and remote start options which add to its user-friendly nature. With a noise level of 74 dB, it is not the quietest option on the market, but it is manageable for its power output class. The run time of 8 hours is decent, though might require frequent refueling during longer outages. At 240 pounds, portability could be a concern despite being labeled as portable, but the included wheel and handle kit help move it around. Maintenance requirements are typical for a generator of this power class, with regular checks needed to ensure long-term reliability. The digital display aids in monitoring the generator's status, making maintenance easier.

The DuroMax XP13000HXT is a robust and versatile option for those needing a reliable power source, though its weight and noise level might be a consideration for some users.
