Your 7,000 Watt Generator MIGHT Your Run Central Air ~ Find Out Why

Your Generator

Central air is one of the most used in an American household, especially during cold and winter days. Electricity interruption is inevitable, but you can do something to keep your needed appliances or units running.

When buying one, you should always buy the right size to avoid any failure or more electrical problems.

Will a 7000-watt generator run central air? A 7000-watt generator can run many appliances, including the central air system. It is powerful enough to run both your central air and refrigerator at the same time. Using one will keep your unit running simultaneously with others without a problem.

It would prove to be an irritating waste of money to buy a generator unsuitable for your needs.

That is why I will address how big of a generator you need to fulfill your power needs in this post.

Deciding The Right Generator Size

Know Your Requirements

Start by calculating the starting & running wattage of the appliance that you need to power.

It will help you decide the right size generator to run the air conditioner. Getting the correct estimate is essential to determine the exact power requirements.

Calculate Size Of Generator You Need

Get the capacity of the appliance. The device weight is measured in tons or BTUs.

You can see it on the label available in the owner’s manual.

Determine The Right Wattage

Multiply the weight by 3,500. With this, you can estimate the generator size for your air conditioner.

Most air conditioner models need up to 3000 watts to run smoothly. So, have the generator sized accurately.

Powering Another Appliance

Find the generator size that can start up several pieces of machinery.

Combine all of the wattages you need to work, plus the starting wattage of all of your devices.

You should apply the wattage of all the things that are meant to operate at the same time.

Some items have higher start-up ratings than run ratings, so to infer the energy needs, use the higher ranking.

Calculating The Power Requirement

By knowing the number of devices that will receive power, you can calculate the power requirements.

But remember that it will take extra wattage to start all equipment to load the appliances inductively.

If you know what appliances to run, you may start adding up the watts. It’s important to remember that the start-up ones need to be added up.

You do not need to worry about overloading a generator once you sum it up and the results are less than 7,000 watts.

However, if it surpasses 7,000 watts, you have to reduce appliances to run in your home.

But that’s only likely if the ones you’re using are less than 7,000 watts. Even when you add the power criteria, make sure to add 10% of the complexity factor.

Consider The Outside Temperature

When the outside temperature and humidity increase, the power needed to start your air conditioner is higher.

Also, the output of the generators decreases. Unfortunately, that implies that you will need a higher power to get your air conditioner operating.

The generator will, in turn, be generating a low energy rating because of the high temperature.

Each air conditioner’s input is steady and usually measured to be 35C outdoors and 27C with 50% humidity indoors.

An increase in temperature raises the device’s need for electrical energy.

For dimensions and fuel efficiency, you can select a popular generator size that is trendy.

The Average Air Conditioner Wattage

For air conditioner units, you will find a vast range of watts. Energy-efficient types, such as large ones, might require as little as 2,000 watts.

The older and larger ones are less efficient, and about 10,000 watts may be required.

Never depend on the size used by your friend or what the web says as the average. The total that matters is your unit’s precise calculation.

Another way of thinking of selecting the best generator size for your home is to determine how much and for how long you’re going to use it.

To a degree, of course, that is volatile. See how any of the three power-outage situations below match the case.

Rarely Lose Power

Even so, for some peace of mind and reassurance, you will want a generator.

  • Mid-sized inverter
  • Recreational inverter
  • Occasional Outages

They are maintained sometimes, but typically not, and you don’t want to spend thousands on a standby generator at home.

  • Large inverter
  • Portable

Areas With Frequent Power Outages

The blackouts are prolonged at times. If you live in a place prone to severe weather events, such as blizzards, ice storms, and hurricanes, this also applies.

  • Home standby
  • Large inverter
  • Portable

What Can A 7,000 Watt Generator Run?

Without any issues, a generator with 7,000 watts will keep your house powered and safe. It can simultaneously operate both AC and a refrigerator.

You can also power two to three refrigerators with this sort of generator, along with light bulbs and fans.

All this uses just 3,300 watts. So for more consumption, you will undoubtedly have a lot of spare capacity.

However, bear in mind that the surge’s strength is still more substantial than the power of running.

So, if all of your appliances are being used simultaneously, surge power will exceed 5,800 watts.

If there is a high wattage for appliances that are already plugged in, you will not power more significant devices.

Until you unplug the other appliances, you can’t.

Here are examples of things you can run all at the same time with 7000 watts:

  1. A 40-gallon water heater
  2. Two hot plates
  3. Two electric stoves
  4. Three window air conditioners.
  5. Three or four microwaves or power machines
  6. Five refrigerators
  7. Six computers
  8. Two air compressors


Essential appliances you have in your home can start and run with a 7,000-watt generator. These are the most common electrical equipment, such as central air, refrigerator or freezer, lamps, and necessary kitchen appliances.

But, do not be too confident of using the 7000 watts generator to power appliances simultaneously.

Always make sure that you have added up all that will be plugged in before using the generator.
