Dehumidifier vs AC: Comparing Cost, Efficiency, and Maintenance


Are you looking for the best way to cool your home? Dehumidifiers and Air Conditioners both provide great cooling solutions but how do you know which is best for you? Learn the differences between Dehumidifier vs AC and discover the perfect cooling solution for your home.

Quick Summary

When comparing dehumidifiers and air conditioners (ACs) for cost, efficiency, and maintenance, there are several key factors to consider. ACs typically have a higher upfront cost, but they can save money in the long run as they use less energy, leading to lower monthly energy bills. Efficiency can also be improved if the unit is placed in the shade; units in the sun can overheat and struggle to properly cool. When it comes to maintenance for both a dehumidifier and an AC, it is important to clean air filters on a regular basis to maintain efficient and healthy air quality. Dehumidifiers tend to need to be drained more often than ACs, but overall, maintenance for both is fairly similar and should be done on a monthly basis.

AC vs Dehumidifier: Cost Comparison, Efficiency, and Maintenance

Cost Comparison

When comparing the purchase cost of air conditioners and dehumidifiers, air conditioners tend to be more expensive than dehumidifiers. Furthermore, the energy costs associated with running an air conditioner can be higher, as these machines require more energy to cool a space.


In terms of energy efficiency, air conditioners typically perform better than dehumidifiers. An air conditioner cools the air to a specific temperature, while a dehumidifier helps reduce the overall humidity in the air. In areas of high humidity, an air conditioner may be the better choice, as it can reduce both temperatures and moisture in the air.


In terms of maintenance and upkeep, both air conditioners and dehumidifiers require monthly cleaning of the filter. This is important to ensure the unit is running optimally and the air is at its cleanest and healthiest.

When it comes to choosing between air conditioners and dehumidifiers, it’s important to consider both the purchase cost and energy costs of running and maintaining the machines, along with the efficiency of the two options.

Personal Experience

  AC vs Dehumidifier: Cost Comparison, Efficiency, and Maintenance

When it comes to dehumidifier vs AC, it really depends on the individual needs of the user. I prefer using a window air conditioner for my home as it has been proven to be very effective at regulating air temperature as well as helping to remove excess moisture from the air. However, for those who do not need to regulate temperature as much, a dehumidifier is an excellent option. These machines work by removing the moisture in the air and releasing cool, dry air back into the room which helps reduce the humidity in the room. Although dehumidifiers can be quite loud, they are usually very energy efficient and do not require much maintenance. Additionally, they can be an important part of preventing condensation, mold, and other humidity-related issues. While there are many pros and cons to both options, a window air conditioner is ultimately my number one choice when it comes to dehumidifier vs AC.

Frequently Asked Questions

Is it better to use a dehumidifier or air conditioner?

It is better to use a dehumidifier when the primary concern is reducing humidity, as it will reduce the moisture without significantly lowering the temperature. An air conditioner will reduce both the humidity and the temperature, making it the better choice when both are needed. Generally speaking, it is wise to use a dehumidifier to address a specific issue with moisture while reserving an air conditioner for situations where both cooling and reducing humidity are necessary.

Do I need a dehumidifier if I have an air conditioner?

No, you do not need a dehumidifier if you have an air conditioner. Air conditioners do have some dehumidifying capabilities, though it’s not their primary purpose. The air conditioner may be able to cool the air past the dew point, causing it to shed some of its extra humidity, though this is not as effective as a dedicated dehumidifier. Therefore, if controlling humidity levels is a priority, it would be best to invest in a dehumidifier.

Does a dehumidifier also cool a room?

No, a dehumidifier does not cool a room. It is designed only to remove excess moisture from a room, not to cool the air. When excess moisture is removed, air feels more comfortable, but the air temperature does not decrease.

Is it worth putting dehumidifier in garage?

Yes, it is worth putting a dehumidifier in a garage. Fixed dehumidifiers control relative humidity levels consistently, helping to prevent the growth of mould, mildew, damp, corrosion, and moisture damage. Installing a dehumidifier in your garage is an effective way to protect against these costly problems.

Will a dehumidifier help cool a garage?

Yes, a dehumidifier can help make a garage feel cooler, even though the actual temperature remains the same. By reducing the moisture in the air, a dehumidifier can make the room feel 5 to 10 degrees cooler. They are a cost-effective, portable, and impermanent solution for cooling down a hot garage.

Do dehumidifiers work better than air conditioners?

Yes, dehumidifiers work better than air conditioners when it comes to reducing humidity. Dehumidifiers can quickly and efficiently remove excess moisture from the air which is not possible with an air conditioner alone. Utilizing both an AC unit and dehumidifier can help keep moisture levels in check, creating a healthy and comfortable environment.

How big of a dehumidifier do I need for a garage?

A 50-pint dehumidifier is suitable for a garage up to 1500 square feet. For damp rooms of 2000-2500 square feet or very damp rooms of 1500-2000 square feet, a 50-pint dehumidifier is suitable. For wet rooms under 1000 square feet, a larger dehumidifier may be needed. Therefore, in order to get the most suitable dehumidifier for your garage, measure the square footage and buy a unit with a higher capacity if it is greater than 1500 square feet.

Do I need dehumidifier with window AC?

No, you do not need a dehumidifier with a window AC. An air conditioner has cold coils that enable it to cool the air, while simultaneously removing moisture from the air. This means that a window AC can both cool and dehumidify a room in one efficient process. Therefore, running a window AC and a dehumidifier at the same time is not necessary.

Which window AC has dehumidifier?

The LG LW1216ER window air conditioner offers the most advanced design, energy-efficiency, and must-have features. It is the best air conditioner you can buy in 2021. Moreover, this unit comes with an integrated dehumidifier, making it the ideal choice for a window AC with dehumidifier.

Do all window AC units dehumidify?

Yes, all window AC units are equipped to dehumidify a given space. Window AC units cool the air which passes over its coils, allowing them to separate the moisture from the air. However, it’s important to note that window AC units can only do so much when it comes to reducing humidity levels in a given space.

How effective is an AC as a dehumidifier?

An AC is quite effective as a dehumidifier. It is able to remove moisture from a room when the temperature is above the AC’s set point by 2°C. This process results in a small amount of dehumidification in cooling mode. This makes an AC an excellent choice for controlling humidity levels in any indoor space.

Are window air conditioners safe?

Window air conditioners are safe to use when properly maintained. Regularly cleaning the air filter is key to keep the air quality clean, and should be done at least once a month. Simply put, window air conditioners are safe when used responsibly.

Can you install an AC unit in a window?

Yes, you can install an AC unit in a window. This can be done if the window is big enough that it provides enough space to open the window and access the area. Additionally, it is not necessary to move or remove the air conditioner in order to access the area. Installing an AC unit in a window is often convenient and cost-effective.

Why are window AC units more vulnerable to fire?

Window AC units are more vulnerable to fire due to their poor installation and usage practices. The study suggests that 38% of AC fires originate with the ignition of an electrical wire or the insulation covering such wires. This highlights the importance of ensuring the correct installation and safe use of window AC units to prevent the risk of fires.

Can a window air conditioner infiltrate outdoor air?

Yes, a window air conditioner can infiltrate outdoor air. If the seal between the air conditioner unit and window is breached, it can allow allergens, pollutants, and other outdoor air from entering the interior space. To reduce infiltration, it’s important to ensure the unit is installed properly, and all seals are in good condition.

Final Thoughts

Dehumidifiers and air conditioners both provide the same basic function of cooling and dehumidifying the home. When it comes to comparison, they both offer cost-effective and efficient options depending on the size and needs of the home. But in terms of maintenance, air conditioners require more frequent filter cleaning, while dehumidifiers require less frequent service. In conclusion, it is important to consider the budget, lifestyle and needs of the home owner when deciding which cooling and dehumidifying option is best for them.
