A dehumidifier and an air conditioner both use electricity to operate. However, a dehumidifier uses more electricity than an air conditioner. This is because a dehumidifier removes moisture from the air, while an air conditioner cools the air.

Do dehumidifiers use a lot of electricity?

As the weather gets warmer, many people start to think about using a dehumidifier or an air conditioner (or both) to keep their homes comfortable. But which one uses more electricity? Interestingly, it turns out that a dehumidifier can actually use less electricity than an air conditioner.

This is because an air conditioner has to work harder to remove moisture from the air, while a dehumidifier only has to remove the excess moisture. Of course, this doesn’t mean that you should necessarily run out and buy a dehumidifier – they can be quite expensive. And if you live in an area with high humidity, you may still need an air conditioner to keep your home comfortable.

But it is something to consider if you’re trying to save money on your electric bill!

How Much Electricity Does a Dehumidifier Use Per Day

If you have allergies, asthma, or any other respiratory problems, you know how important it is to keep the air in your home dry. One way to do this is to use a dehumidifier. But how much electricity does a dehumidifier use per day?

The answer depends on the size of the dehumidifier and the humidity level in your home. A small dehumidifier that removes about 50 pints of water per day will use about as much electricity as a 100-watt light bulb. A larger unit that removes 70 pints of water per day will use about 200 watts of power.

To get an idea of how much your particular dehumidifier will cost to operate, look at the EnergyGuide label. It will tell you how many watts of power the unit uses and estimate how much it costs to run for 24 hours. For example, if the label says the unit uses 200 watts and estimates that it costs 30 cents per day to operate, you can expect your monthly electric bill to increase by about $9 when you use the dehumidifier daily.

Of course, these are just estimates. Your actual electric bill may be higher or lower depending on the cost of electricity in your area and how often you run the dehumidifier.

Ac Dehumidifier Mode Electricity Consumption

Dehumidifiers are a great way to keep your home free of excess moisture, but they can be a bit of an electricity hog. That’s why it’s important to know how much power your dehumidifier uses so you can make sure it doesn’t put too big of a dent in your monthly electric bill. The average dehumidifier uses about 725 watts of power, which means that it costs about $0.90 per day to operate.

However, there are some newer, more energy-efficient models on the market that use as little as 400 watts. To find out how much your specific dehumidifier model uses, check the label or manufacturer’s website for its electricity consumption rating. Keep in mind that this rating is for when the unit is operating at full capacity – most models have different settings that use less power.

If you’re concerned about saving money on your electric bill, consider investing in an energy-efficient dehumidifier. These models often pay for themselves within a year or two through lower electricity bills.

Should You Run a Dehumidifier And Air Conditioner at the Same Time

If you live in a humid climate, you may be wondering if it’s necessary to run both a dehumidifier and air conditioner at the same time. The answer is yes! Here’s why:

Dehumidifiers work by removing moisture from the air. This helps to prevent mold and mildew growth, as well as reducing dust mites and other allergens. However, dehumidifiers can only do their job effectively if the air conditioner is also running.

Why? Because the air conditioner helps to circulate the air throughout your home, which allows the dehumidifier to do its job more efficiently. So, if you live in a humid climate, make sure to run both your dehumidifier and air conditioner at the same time!

Dehumidifier Power Consumption

When it comes to dehumidifiers, one of the most important factors to consider is power consumption. After all, a dehumidifier that consumes a lot of power can end up costing you a lot of money in utility bills. So, how much power does a typical dehumidifier use?

It depends on the size and capacity of the unit. A small, personal dehumidifier might use as little as 50 watts of power, while a large industrial unit could use 3,000 watts or more. To get an estimate of how much your particular dehumidifier will cost to operate, you’ll need to know two things: the capacity of the unit (in pints per day) and the power consumption (in watts).

Here’s a quick formula to help you calculate estimated operating costs: Dehumidifier Capacity (pints/day) x Power Consumption (watts) / 1000 x Cost per kWh = Estimated Operating Costs ($) For example, let’s say you have a small personal dehumidifier with a capacity of 20 pints per day.

If it uses 50 watts of power, your estimated operating costs would be $0.20 per day ($0.10 per hour). Of course, this is just an estimate – your actual costs will depend on your local electricity rates.

Dehumidifier Vs Air Conditioner Reddit

When it comes to choosing between a dehumidifier and an air conditioner, it can be tough to decide which is best for your needs. If you’re trying to figure out which one is right for you, there are a few things you should keep in mind. The first thing to consider is the climate you live in.

If you live in an area with high humidity, then a dehumidifier will likely be the better option. On the other hand, if you live in a drier climate, an air conditioner will probably be better suited for your needs. Another thing to keep in mind is the size of your home.

If you have a large home, then an air conditioner will likely be more effective at cooling it down. However, if you have a smaller space, then a dehumidifier might be all you need. Finally, consider your budget when making your decision.

Dehumidifiers can be quite expensive, so if cost is a factor, then an air conditioner might be the better option for you.

Is It Cheaper to Run a Dehumidifier Or an Air Conditioner?

Assuming you are asking about whole-house units: It is cheaper to run a dehumidifier. Dehumidifiers do not cool the air, they only remove moisture.

An air conditioner will cool the air as it removes moisture. The Department of Energy estimates that for a 2,000 square foot home, running a dehumidifier will cost $35 per month while running an air conditioner will cost $50 per month.

Do Dehumidifiers Run Up Your Electric Bill?

A dehumidifier can actually help you save on your electric bill because it helps to remove excess moisture from the air. This can prevent your home from feeling stuffy and damp, and can also help to prevent mold and mildew growth.

Can I Use a Dehumidifier Instead of an Air Conditioner?

Yes, you can use a dehumidifier instead of an air conditioner, but there are some things to keep in mind. Dehumidifiers work by removing moisture from the air, which can make your home feel cooler and more comfortable. However, they will not lower the temperature of the air like an air conditioner.

This means that if your home is already cool, a dehumidifier may not be necessary. Additionally, dehumidifiers are not as effective as air conditioners at removing pollutants from the air, so if you have allergies or asthma, an air conditioner may be a better option.

Will a Dehumidifier Lower My Air Conditioning Bill?

Dehumidifiers can actually help you save money on your air conditioning bill. By lowering the humidity in your home, dehumidifiers make it easier for your air conditioner to cool the air. This means that your air conditioner doesn’t have to work as hard, which uses less energy and ultimately lowers your utility bills.


No, a dehumidifier does not use more electricity than an air conditioner. In fact, a dehumidifier can actually help you save on your energy bill by reducing the amount of time your air conditioner needs to run.
