Quickly and easily set up by professional installers, the Generac Guardian easily attaches to your existing LP or NG pipes and comes with a five-year limited warranty and 24/7/365 customer phone support.

Briggs & Stratton 12,000-Watt Automatic Air Cooled Standby Generator

The Briggs & Stratton 12,000 Watt Generator packs quite the punch for a narrow footprint unit and ships at a solid price. Though one of the smallest generators on our best-of list, this product delivers a solid 12,000 watts and comes in as one of the best ranked generators by customer reviews.

While the Champion 14-kW aXis generator is one of the most expensive whole house generators on our list, it includes excellent features to help it stand apart from its competition. Offering a best-in-class 14,000 watts, the Champion aXis goes unmatched on this list for the amount of power it outputs to your home. This generator is also the quietest of our top five with noise measured at only 62 dbA.

The Champion aXis is designed to start automatically when your home’s power is lost, evenly manage the electric load and operate at sub-zero temperatures or in extreme heat.

Generac PowerPact 7,500 Watt Standby Generator

If you have a small home or need fewer watts of power, the Generac PowerPact 7,500 Watt Standby Generator is a great option. The PowerPact includes most of the same features as Generac’s larger models while requiring the smallest footprint of those we’ve ranked.

You get what you pay for, though: this PowerPact only includes a three-year limited warranty and is one of the loudest options, measured at 69 dbA. The PowerPact includes a lightweight, indoor-rated automatic transfer switch and can power up to eight circuits of your home.

Generac Guardian 3-Phase 20kW Automatic Standby Generator Wi-Fi Enabled

The Generac Guardian 3-Phase 20kW generator is one of the largest, most powerful air-cooled 3-phase generators on the market.

This generator has all the features you’ve come to love of a Generac, easy-installation, Wi-Fi control and monitoring, and durable, all-weather construction that’s built to last. With a noise level of 67 dbA, this unit’s noise is impressively low for the level of power output. The only thing missing from this package is an automatic transfer switch, which is sold separately.

When the lights go out, a whole house generator can be an essential tool when you need power in a pinch. The most powerful generator you can buy, a whole house generator is wired into the electric panel and automatically turns on when the lights go out.

When purchasing a generator, the most important determination is the power requirements of your house and especially your large-draw electric appliances. Refrigerators, air conditioning, sump pumps, water heaters and space heaters will have some of the highest power draw in your house.

Online wattage calculators will help you find what size generator is the best fit for powering your whole house. You can also calculate this yourself by finding the wattage rating label on each of your electrical appliances.

You should multiply the total watts of your appliances by at least 1.5 to create an adequate margin of safety. You can also check with your power company or on your electric bill to find your regular power needs. In general a small to medium size U.S. house averages a minimum of 5,000 to 7,000 watts so many standby generators are sold with a minimum of 8,500 to 10,000 watt outputs.

NOTE: Some generators are listed by watt (W) and some by kilowatt (kW). A kilowatt is 1000 watts.

An air-cooled generator uses the surrounding air to cool the engine. This could be done passively by the surrounding air absorbing the heat and rising away from the generator, or this could be accomplished with “forced air cooling” which uses a fan to blow air across the generator’s engine. Air-cooled generators will often not work as well for longer-run, whole house applications because the cooling is not as efficient—units are more likely to overheat and shut down automatically.

A liquid-cooled generator pumps coolant through the engine block which absorbs heat from the engine before moving through a radiator where the coolant cools back off and then is cycled through again.

The advantage of liquid-cooled generators is they can operate more efficiently, without the fear of overheating in climates that regularly get above 100 degrees Fahrenheit. Liquid-cooled generators are best for whole house applications because these units are less likely to overheat.

Whole house generators are permanently installed at your home and connect to your house’s gas line, either liquid propane (LP) from a tank installed on your property or natural gas (NG) from a utility line or custom tank. Propane is a more affordable fuel and burns “clean”, meaning it leaves much less contamination.

Natural gas is advantageous because it doesn’t require refilling a tank, but a utility mainline can be a disadvantage for those who want to remain off-grid.

Many whole house generators can burn either type of fuel with a simple conversion. Make sure to purchase the correct generator for the type of fuel that you have available.

Since these generators will likely be permanently stationed aside your house, the noise level is an important consideration when choosing a generator. Generally, the Generac brand whole house generators run on the quieter side—65 dbA or less—while other manufacturers’ models may run at 69 dbA or even higher. For reference a vacuum cleaner runs at 75 dbA. Placement of your whole house generator is also important since you may not want that loud noise right next to a bedroom or office.

Compare Quotes From Top-Rated Generator Installers

A proper whole house generator is designed to back-up essential appliances like your air conditioner, sump pump and refrigerator as well as power your whole house and everything inside of it. Whether this added power gives you peace-of-mind knowing you won’t have to sacrifice your electrical needs during a power outage or takes your house off grid and becomes your only source of power, a whole house generator will keep you running at full capacity.

Whole house generators install permanently outside of your home so whether you’re using them as back-up when the power goes out or as your main source of power, they’re designed to be ready whenever you need them. The units run on liquid propane (LP), natural gas (NG) or even diesel and are generally hooked up to a large, permanently installed fuel tank or to the gas mainline so you don’t need to worry about going to the store to buy fuel when you need power.

Whole house generators typically have even higher power capacity than stand-by generators with power capacities ranging from 22 to 48kW. These generators feature larger, more powerful and often liquid-cooled engines so they can run for significantly longer without maintenance needs or overheating.

To determine the best whole house generator ranking, the Forbes Home Improvement editorial team analyzed third-party data on dozens of whole house generators, with each product’s star rating determined by evaluating a variety of metrics, including:

*Price and warranty are 50% of the total weighting.

The best whole house generator depends on a number of variables, especially the power requirements of your home and on the electrical appliances you are hoping to run. Our top five generators are listed above with the Generac Guardian 10,000W topping the list because of its overall great performance, noise level, price, warranty and solid customer reviews.

The average U.S. home needs a minimum of 5,000 to 7,500 watts to power the critical electrical needs. For this reason, standby generators usually provide between 9kW and 20kW. Common whole house generator power capacities begin at 22,000 watts and go up from there, usually topping out near 50,000 watts.

Most homeowners can expect to pay between $1,500 and $7,500 for generator installation with the average cost being about $4,500. The exact cost can depend on a number of variables and features and will differ depending on labor costs in your area.

Studies of whole house generators have found a reliability of around 99%. While these generators are designed to last, constantly running engines causes common wear and tear issues on batteries, belts, hoses and fluids so regular generator operation and maintenance is the best way to guarantee reliability.

Installing a whole house generator by yourself is not an easy DIY project and should only be attempted by seriously experienced handypeople. The installation requires electrical wiring and plumbing of flammable fuels. For safety reasons, and to ensure adherence to local codes, we highly recommend hiring a professional installer.
