When summer is here, we run away to cool places, seeking refuge from the intense heat we experience in homes through air conditioners. Nevertheless, many people need to acknowledge that air conditioners can be handy in managing humidity levels. This detailed guide will show you how to turn your air conditioner into a dehumidifier and make your home nicer and healthier.

The relationship between air conditioning and dehumidification

Let us quickly discuss how air conditioners usually aid in desiccation before delving more deeply into the practical steps. The air conditioner mainly cools the air, which involves removing heat. The air conditioner draws humidity out of the air along with cooling it. As a result, humidity is reduced.

Standard air conditioners may be designed more than just to dehumidify; their efficiency depends on some factors. You can improve the humidifying abilities of your air conditioner by using specific techniques with a bit of change.

Transforming your air conditioner into a dehumidifier

Choose the Right Air Conditioner:

However, not every air conditioner is created for dehumidification. Go for newer units with improved dry-out capabilities if you want one. Go for air conditioning units with variable fan speed and humidity control systems.

Regular Maintenance:

Always check on your air conditioner’s status and ensure it is always in good working condition from time to time. Use or replace the air filter as specified in the manufacturer’s recommendation. A blocked filter will lower the airflow, making it less effective in removing heat and moisture.

Optimal Temperature Settings:

Ensure you set your air conditioner at the right temperature for dehumidification. Moisture gets removed when it cools down. Thus, there are fewer chances of dew formation in such a situation. To achieve success, ensure the temperature is between 68 and 72 degrees Fahrenheit.

Use the “Dry” Mode:

Most of the latest models for home air conditioning are usually accompanied by “dry” or “dehumidified” functions. It is a priority to achieve dehumidification rather than cooling in this mode. Select this operation when your concern is low humidity and not major dehumidification.

Invest in a Dehumidifier Attachment:

Some Air Conditioners come with the ability to integrate a Dehumidifier accessory.
These add-ons increase your unit’s ability to dehumidify, however. You must check the air conditioner’s owner’s manual or consult the manufacturer.

Positioning Matters:

The demisting efficiency of an air-conditioning machine depends on how it is placed. Ensure that you put it in one convenient, well-ventilated spot. Do not put furniture or anything else which can obstruct air blowing.

Seal Air Leaks:

Properly insulating your house and sealing air leaks can help control humidity efficiently. Be sure to check the door and window areas for any possible leaks, filling them appropriately. You can also use it to enhance your air conditioner’s performance and boost total energy efficiency in your house.

Use a Programmable Thermostat:

Buy a programmable thermostat to set air conditions at maximum. To conserve energy, program it and leave the thermostat in a higher setting to maintain some humidity when you are away.

Consider a Smart Home Integration:

Consider using remotely controlled smart homes for regulating air conditioners. Some modern thermostats are designed to manage humidity, and one may readily operate them with a mobile device.

Additional Tips and Considerations

Regularly Check and Empty the Drain Pan:

Ensure that there is no dirt or other obstructions in the drain pan beneath the evaporator coils. Discard this container regularly because when water is present in it, mold will start growing inside.

Maintain Adequate Ventilation:

This helps prevent moisture build-up and must, therefore, be properly ventilated. Vent out damp air from the kitchen and bathroom using exhaust fans. This supports the dehumidification by the air conditioner.

Monitor Humidity Levels:

Ensure that you purchase a device called a humidity controller, popularly known as a hygrometer, to monitor the humidity levels of your house. Consider setting the relative humidity at 30-50%. Set your air conditioner accordingly to keep it at optimum range.

Consult with HVAC Professionals:

However, if the humidity issues persist, it is best to seek professional advice from the HVAC experts. They can scrutinize your system, advise you on upgrading, or suggest customized solutions.


Changing the air conditioner and making it a dehumidifier for improving indoor comfort is a very possible and economical way. These steps will make your home comfortable and dry throughout the summer with appropriate cooling temperatures indoors. Remember that every house is unique. Try to change some variants of this adjustment to create a convenient combination for you!

FAQs – How To Make Yours AC a Dehumidifier

Q1: How do some air-conditioning devices dehumidify naturally in this process?

A1: As the air conditioner extracts the heat out of the air, it cools the air. In that regard, such devices also remove moisture, reducing humidity levels. The warm air passes over the evaporator coils, resulting in condensation, which eliminates the water vapor.

Q2: Does every air conditioner possess a dehumidifier function?

A2: Indeed, most air conditioners have humidity functions as a typical feature. However, the effectiveness can vary. Specific models feature modes such as “Dry” or “Dehumidify,” specifically for enhancing dehumidification.

Q3: What is the optimum temperature setting for dehumidification?

A3: One should set the air conditioning at the coolest level possible, usually between 68 and 72 degrees Fahrenheit. While this causes more moisture in the air to be drawn into the unit, it helps for the best dehumidification. Try out different settings until a mixture of cooling and dehumidification settles for your convenience.

Q4: Where do I start with this question? Should I clean or replace my air conditioner’s filter every how often?

A4: The manufacturer should be followed when cleaning or replacing the air filter. Failure to clean a contaminated filter hinders air passage, which affects the effectiveness of cooling and dehumidification. Good performance is due to regular operation and care of filters.

Q5: Are there particular air condition units meant for efficient dehumidification?

A5: Some of these air conditioners have added dehumidification properties. Search for units with adjustable fans, changeable humidity controls, and specific dehumidification settings. For information on product specifications, check with the supplier or manufacturer.

Q6: Can I install a dehumidifier on any air conditioner?

A6: However, not all air conditioners have dehumidifier attachments. Before making a choice, determine whether some dehumidifier accessories are compatible with your air conditioner by reading the user’s manual or contacting the manufacturers.

Q7: What would better humidity control have with smart home integration?

A7: Smart thermostats connected through a smartphone application help monitor and adjust humidity from anywhere. It has various features that help adjust temperature according to personal preference while enhancing energy saving.

Q8: What would be the optimal indoor relative humidity range?

A8: Sufficient internal comfort typically occurs within 30% – 50% relative humidity. You can invest in a hygrometer to maintain the humidity level within this range.

Q9: Do air leaks have any effect on dehumidification?

A9: Absolutely, air leaks will affect the dehumidification process. Insulating properly and sealing air leaks make the humidification control more effective, allowing AC to work effectively.

Q10: Should I see a professional in case of constant humidity problems?

A10: One should visit an HVAC professional if humidity-related problems persist. These professionals can check your system, offer advice on what should be improved, and design customized humidification measures for the unique issues in your house.
