Why Do I Need A Right Size Generator To Run A 13,500 BTU AC?
Air conditioners aren’t quite like the other appliances that are pushed through by the fan and motor, which switch on and off as needed.
This means it will need to consume the maximum amount of electricity it can pull on a regular basis to keep the room at the ideal temperature.
This is usually why you’ll notice that your generator dies more frequently when the weather becomes cooler. When it’s hot outside, the air conditioner stays on; however, when the room is near to the ideal temperature, it turns on and off.

Other Appliances Using With AC
Your other appliances with an AC can consume a surprising amount of energy. When choosing or looking for a generator knowing how much energy you use to run your home may be eye-opening for most individuals since it indicates where you may be squandering energy.
Space In Your Home

Usage in General

Most of the time, you can figure out what your generator will need to run. If you want to use your generator during storms or hot weather, keep in mind that you’ll need air conditioners during those times, while heaters will be required during the cooler months.
How To Use A Generator Properly To Run A 13,500 BTU AC?
When using a generator, an air conditioner is frequently unable to operate since it is being used incorrectly for the system.
There are a few more measures that will guarantee that your generator is not overworked and that your air conditioning performs optimally.
Only Use It If It’s Really Necessary
Our advice is to reconsider the method of cooling their houses since using the air conditioner only when the temperatures get uncomfortable is far more effective. Because air conditioners are not air filters, this will save a lot of energy and help keep disease at bay.
Run Just One At A Time
When using a generator, all air conditioners should be switched off, and everyone should ideally be working in the same room.
This enables maximum efficiency because the air conditioner in that room can chill it pleasantly without having to compete with other appliances for electricity.
Don’t Turn It On And Off All The Time
There is not necessary to switch your air conditioners on and off several times an hour. This wastes a lot of energy, but it’s even more inefficient and harmful when done on a generator.
Enabling the air conditioner to do its job or allowing natural air to circulate through your home, the air conditioner must be turned on or off.
Temperatures should be adjusted
If it’s really hot outdoors, you should be aware that trying to chill the workplace improves overall efficiency and allow the generator to run more comfortably.
If it’s cooler outside but you’re still hot, try allowing more natural air into the room.
Windows and doors should be closed
Another thing is when an air conditioner is turned on are to open doors or windows.
This completely undermines the system’s impact and forces it to expend a lot more energy in order to cool a much bigger area that is continually flooded with hot air.
FAQs About The Right Size Generator To Run A 13,500 BTU AC
1. What To Do With The Noise Level Of A Generator To Run A 13,500 BTU AC?
Ans: The optimal generator noise level is between 50 and 60 decibels, with the generator mounted on the backside of your generator so that the majority of the noise is deflected away from your campground.
Also placing a couple of pieces of chipboard against the generator to reflect the noise into the ground can reduce the noise level.
2. Can A Portable Generator Run A 13,500 BTU AC?
Ans: A portable generator may be used to power an air conditioner, however, it must have a minimum power output of 4000W.
When a small room air conditioner is first turned on, it consumes roughly 3500W of power, which gradually decreases as the house cools.
3. What Should I Do To Get My Generator To Work Properly While Running A 13,500 BTU AC?
