What Is the Best Generator for Central Air?

Best Generator for Central Air Overview

Air conditioners play a crucial role in any home because they help you remain comfortable no matter the weather outside. But what happens when the power goes off?

This is where a generator for central air comes in handy. Let’s look at the best one for your home.

Best Generator for Central Air?

A portable generator can run a 2.5-ton air conditioner, but if you have a larger unit, you’ll need a more powerful unit. A 10,000-watt generator will run a two-ton unit. Weight is measured in BTU and air pressure, so you’ll need a higher-wattage generator than a portable one.

For most households, a twenty-kilowatt generator is enough. If you’d like to use your power generator to power your refrigerator, you’ll need a higher-watt-rated one.

To choose a generator that will power multiple ac units, make sure to get one with more power than the combined wattage of all the units. This will prevent power fluxes, which can damage the appliances in the system.

If you’re unsure of your home’s total wattage requirements, add up all of the wattage requirements of all appliances. Keep in mind that some items need higher power to start than they do to run, so be sure to choose a unit with a higher startup rating.

Portable generators have become more efficient and have higher power capacity. A 2,000-watt generator can easily power a single fan and lamp, while a three-ton unit can power several systems for a period of time.

If you need to run a two- or three-ton AC, a three-ton model will do the trick. It also powers the essential electric devices, such as a TV and radio.

Its engine delivers rated power of 9500W and has a maximum running capacity of 12,500W. Its four-stroke, overhead valve engine delivers a smooth and easy start.

It weighs approximately 220 pounds and is easy to maneuver. It has an automatic ignition, AC outlets, and a lift bracket for portability. This generator also offers a three-year limited warranty.

While the WGen9500DF is easy to maneuver, it doesn’t provide stable and clean power. The THD rating of 23% is too high for sensitive electronic devices. And the unit runs at 73 dBA, which is far higher than the safe limit for portable power.
