In general, you need at least one 4000 watt generator to run a small window air conditioner unit and at least one 6000 watt generator to run a whole house air conditioner. An air conditioner requires a lot of energy, so you usually can't use your generator for anything else at the same time. Yes, a portable generator can power your central air conditioning unit. Portable generators not only serve to power small appliances, but they can also keep energy-intensive home systems running during power outages. It is essential to make sure that you choose a portable generator that is strong enough to run the air conditioner and any other essential systems that you plan to connect it to.
With a 1000 watt generator, you can run a small or medium window unit and be fine. You will need at least a 2000 watt generator to power a large window unit. A larger generator may be a better option if you need to power many appliances at once. Whole House Generators are great for powering your air conditioner during a power outage. However, air conditioners range from 900-watt window units to 4000-watt whole-house air conditioners, so it's essential to get a generator that can handle the load of your particular unit.
Standby generators have the power to power central air conditioners, so you can return to a fresh home. A 14-kilowatt standby generator could power a 4-ton central air conditioner, while a 17-kilowatt model could work with a 5-ton central air conditioner. Although they won't power a central air conditioner, you can connect two units in parallel to power your other appliances for a longer period of time. The electrician will need to install a manual transfer switch to connect the generator to the electrical panel. Connecting the air conditioner to your generator is easy or difficult, depending on the type of configuration you have. To understand what size generator you need for your AC window, you must first consider the watt consumption of your window air conditioner unit.
The power of a generator determines its output power, and the basic rule is to buy a generator with an output power at least slightly higher than what the air conditioner needs. It's essential to make sure your generator is always in good condition, or you may end up with a costly breakdown or have to replace it. Generators come in a huge variety, differentiated mainly by their electrical production capacity and battery life. If the size and installation of an emergency portable generator exceeds your budget, you can always buy a smaller portable generator and simply connect it to a window air conditioner. In general, determining the size of generator you need for a window AC unit will depend on many factors, such as the size of your home and the amount of cooling power you need.
If you want a top of the line generator that comes in several sizes, then a Generac generator is the one for you. It is important to check these figures for anything else that wants to start the same generator simultaneously to avoid any failure. Get your generator several weeks or months before the hurricane season, which is approximately June-November. A freezer only uses 100 to 300 watts, so your generator should have no problem powering these appliances. Portable generators with low power are designed for smaller appliances that are used in emergencies until the power is turned on again.
Here is a complete list of appliances, lights and outlets that you can power along with your air conditioner with a Generac generator.
