Liquid Cooled Generator VS Air Cooled Generators

When it comes to purchasing a standby home generator, one of the key decisions you need to make is whether to choose an air-cooled or a liquid-cooled generator. Both have their own unique set of advantages and disadvantages, and the decision you make will depend on your specific needs and requirements.

Air-Cooled Generators

Air-cooled generators work by using an engine that is cooled by air flowing over it. These generators are typically smaller and more compact than their liquid-cooled counterparts, making them easier to install and maintain. They are also generally less expensive than liquid-cooled generators, making them a more cost-effective option for many homeowners.

One of the main benefits of air-cooled generators is that they require less maintenance than liquid-cooled generators. This is because air-cooled engines have fewer moving parts and do not require a separate cooling system. They are also generally more fuel-efficient, which means you'll spend less money on fuel over time.

However, air-cooled generators are not as powerful as their liquid-cooled counterparts, which means they may not be able to handle as much power. They are also not as reliable in extreme temperatures, such as during heatwaves or cold snaps.

Liquid-Cooled Generators

Liquid-cooled generators use a separate cooling system to regulate the temperature of the engine. This means they are able to handle more power and are generally more reliable than air-cooled generators, especially in extreme temperatures. They are also more fuel-efficient than air-cooled generators, which can save you money in the long run.

However, liquid-cooled generators are typically more expensive than air-cooled generators, and they require more maintenance. This is because they have more moving parts and require a separate cooling system, which needs to be maintained regularly.

Which Generator is Right for You?

When deciding between an air-cooled or liquid-cooled generator, there are several factors to consider. These include your power needs, budget, and maintenance requirements.

If you have a smaller home or only need to power a few essential appliances during an outage, an air-cooled generator may be sufficient. They are generally less expensive and require less maintenance, making them a more cost-effective option.

On the other hand, if you have a larger home or need to power a wider range of appliances and electronics, a liquid-cooled generator may be a better option. They are more powerful and reliable, but they are also more expensive and require more maintenance. Generac’s Guardian Series generators provide the automatic backup power you need to protect your home. Connected to your existing LP or natural gas fuel supply, it kicks in within seconds of sensing power loss—automatically—and runs for as long as necessary until utility power returns. Choose from Generac’s industry leading lineup to power just the essentials or Generac’s 26kW, the largest air-cooled generator in the market, for whole-house coverage, but we usually find that 22kw or 24kw is more than enough to power most homes in America and we keep both in stock. 

Ultimately, the decision you make will depend on your specific needs and requirements. It's important to consider all of the factors involved, including price, reliability, and maintenance, before making a decision. By doing so, you can ensure that you choose the generator that best meets your needs and provides reliable backup power during an outage. Both Generac and Kohler are excellent choices for both types and we can help you decide which is best for you with the best prices.
