Dehumidifier vs AC: Which Is Better?

Dehumidifier vs AC: Which Is Better?

Sharing is caring!

We all love that refreshing moment when we walk from the hot outdoors into a nice, cool building. Or how about when we go down into the basement and find no trace of humidity? That’s always great, right? Nothing worse than a damp and dingy basement. Many of us have grown to depend on household appliances such as air conditioners and dehumidifiers. However, the question remains: what’s the difference and which one of these is overall better than the other?

The question of dehumidifiers vs ac is a well-known debate. The answer to this question lies with which one suits a person’s individual needs the best. Let’s have a look at the two and then you can decide for yourself.

Dehumidifier vs AC Comparisons


Air Conditioner


  • Circulates hot air and creates cold blasts
  • Removes hot air to the outdoors
  • Does not remove fungus



  • Remove moisture from the air
  • Leave hot air indoors
  • Removes fungus

Dehumidifier vs AC Pros & Cons


Air Conditioner


  • Provides more relaxing environment by easing allergies and effects of heat
  • Increases a person’s physical activity level


  • May not be able to handle the level of heat generated (too many appliances in use)
  • Possible bacteria growth due to moisture



  • Prevents possible mold growth
  • Able to be set up wherever you prefer in the home


  • Adds significant extra cost to electric bills
  • Need to be cleaned and tended to regularly

Taking a Closer Look


Once you have determined which one of these appliances will work best for your needs, it is time to examine the different types. Not all air conditioners and dehumidifiers are the same; they are all differentiated by a few crucial details. Even when looking at dehumidifier vs air conditioner power consumption, you’ll get varied results.

Types Of Air Conditioner

Window Air Conditioners

These units are installed in a window that is partially open. They are not used to cool down the entire house, therefore the energy efficiency is higher with this type.


This is a type of system that is placed on the inside of a room. Hot air is taken from the house using a hose vent. These systems are easily moveable and capable of being placed wherever you wish them to be.


This is a system that has two separate units (outdoor and indoor) and it does not require use of ducts. The indoor unit carries the power to the outdoor unit.


Central air conditioning is used to cool entire buildings, as opposed to singular rooms. The system uses a large compressor to produce the cooling effect.

Types Of Dehumidifier


A chemical known as ‘desiccant’ is used in this dehumidifier with the purpose of absorbing and releasing moisture. It is a good machine in regards to consistency. Desiccant units tend to avoid power fluctuations, which can reduce the electric bill.


This system utilizes something called a ‘Peltier module’. Electricity gets run through the module, leaving one side of the module cold, and one side hot. The cold side is where the air loses its humidity

Refrigerated Coil

These dehumidifiers work in a way that is similar to refrigerators. Hot air is passed through the fan and the refrigerated coil. The coil traps the moisture from the air, thereby removing the humidity.

Examining The Options

So now that we understand the difference between the two machines, let’s try focussing in more specifically about what you’re looking for. Whether you want a dehumidifier, an air conditioner, or both, you need to decide which features are the most important to you. Different products all have their pros and cons, but these are a few that stood out favourably.

If you have no excess moisture issues in your home, you will likely be looking at an air conditioner vs a dehumidifier. If you just want something simple, perhaps for only one or two rooms, then one option in particular is the Honeywell MN10CES. It is small and portable, and does not use as much energy as central air does.

Another reason to consider a dehumidifier is the health benefits that they provide to you and your family. You can read more on that here. If someone in your family has asthma, or if you are simply conscious about good health, try looking at the Frigidaire 35-pint model. Seeing as this unit can remove 35 pints of moisture from your home every day, it is definitely considered to be a highly capable machine.

Looking at dehumidifier vs ac cost. If price is a determining factor for you then there are cost efficient alternatives for each. An ac unit can be fairly pricey, but you can get cheaper models that install in an open window. As for dehumidifiers, they all tend to fare well in pricing, making them quite affordable, unless you’re looking at installing a permanent system in your home.

What’s the deal with a dehumidifier vs ac dry mode? You’ve probably never heard of a dry mode on an ac unit before, have you? It’s a function that actually helps reduce the moisture in the air for those extremely hot and humid days. So, given this information, you could probably use an ac unit to tackle both of your needs and skip a dehumidifier altogether.


So once again, we are asking ourselves which is better: dehumidifiers or air conditioning units? They are both extremely useful inventions that improve the quality of life all around the world. Personally, I use a Whynter portable unit (from Amazon). This is because I enjoy its compact shape, making it easier to move to different rooms.To conclude, air conditioners remove the hot air from your home, while dehumidifiers decrease the level of humidity in the air. And when looking at dehumidifier power consumption vs air conditioner, it does seem that a dehumidifier is best, in that regard.They work well if they are paired together, yet they also function completely fine independently. Do you think you’ll need one of these? Or maybe you’ll need both. Hopefully this article can aid you in that decision.Let us know if you have any further questions about air conditioners or dehumidifiers! Did a particular product work well for you?
