How does the dry setting on a window AC unit work? The dry setting just runs the compressor and fan at a lower speed. This allows some water to condense on the evaporator (the part that gets cold) without cooling the room as much as the cool setting.
The best way to dry out air handler coils is to use a dehumidifier. Another option is to set your air handler's fan switch to on. The constant moving air will help to dry out the air handler insulation.
Waiting for at least 24 hours is recommended after cleaning an air conditioner. Your appliance will dry out completely during this period. In the meantime, there are more steps you can take to speed up the drying process.
It is recommended to keep the dry mode on for no more than two hours at a time. Once the dry mode has been longer than the recommended time interval, it can cause dry skin, cracking in the drywall, lackluster indoor plant health, and other problems.
Set the Fan to AUTO
As the refrigerant coils in your air conditioner absorb heat and moisture, cold air is blown in. The moisture stays behind and collects on the coils. If you keep the fan set to ON, the moisture will continue to be blown back inside.
Moisture will cause acid to form in the system causing serious damage to the compressor and expansion valve parts. It also deteriorates the insulation of the motor windings in the compressor.

Contrary to popular belief, your air conditioner doesn't put in cool, dry air in your home—it removes heat and humidity. The process involves refrigerant, which soaks up heat and moisture effectively from the indoor air.
Generally, it can take anywhere from 15 minutes to a few hours to significantly reduce humidity levels. For best results, the AC should run in cycles, with each cycle lasting at least 15-20 minutes. Short cycles may cool the air but won't run long enough to remove much moisture.
The answer is yes. Air conditioners are designed to withstand normal weather conditions, including rain. The outdoor components of most AC systems are built with a durability that allows them to operate effectively, even when exposed to water.
Never use acid-type cleaners indoors. Always spray downwind when cleaning outdoor condenser coils. Use a gentle hose nozzle to rinse off chemical cleaners, never a high-powered pressure washer.
Dirty evaporator coils and clogged air filters can hinder your air conditioner's ability to dehumidify the air. When the evaporator coil is dirty, it can't absorb heat and humidity as effectively. Similarly, a clogged filter restricts airflow, reducing the system's overall efficiency.
3.Give the AC coils some time to dry up
You can easily do this by switching off your unit or setting your unit on the fan mode and leave it in this mode for around 24 to 48 hours to break down the accumulated ice and start working properly.
Dry mode only needs to slowly pass air over the evaporator coils while cool mode needs to pass air over them with more power. When an AC unit runs on dry mode, it uses less electricity than the same AC unit running in cool mode. This makes dry mode the ideal choice when the weather is humid but not necessarily hot.
Dangers of Water in Air Ducts
A considerable threat of water in your air ducts is not knowing it is there. Even without the clear signs of water forming around your ducts, moisture can be building up — and that build-up has dire consequences. Water damage can devastate your home.
Dry mode or dehumidification offers you and your family many advantages. It not only contributes to a healthier and a more comfortable environment, it can also save you significant money in the long run.
Ceiling fans can be extremely beneficial in reducing humidity in a home because they are able to keep air circulating across an entire room and from the top down. Even a fan spinning at a low speed can help drastically with air circulation and lowering humidity.
How to Use "Dry Mode" on AC: Locate the "Dry Mode" Setting: On your AC remote or control panel, look for the "Dry Mode" icon or setting. It is usually represented by a water droplet symbol. Set the Desired Humidity Level: Some AC units allow you to set the desired humidity level manually.
But as mentioned above, you shouldn't run dry mode for more than an hour or two to lower the humidity. You can lower your cool mode running costs by only having your air con switched on when you need it, and not having your temperature level set too low.
WHAT IS THE BEST MODE FOR AC IN SUMMER? In summer, the best mode for your air conditioner is the "Cool" mode, set to a comfortable temperature around 78°F when you're home. This setting efficiently reduces indoor humidity and maintains a comfortable environment without overworking the AC system.
Moisture buildup or condensation on closet walls or room ceilings and walls also indicates high humidity. Humidity should be monitored daily since outside temperatures will change. Consider purchasing a digital hygrometer (inexpensive and widely available) and check it regularly.
The good news is that you absolutely can spray water on your air conditioner if it needs a cleaning, and nothing bad will happen. Spraying water on your AC's condenser also helps it run more efficiently. In fact, your condenser needs a regular spritzing in order to keep doing a good job.
Ice Build-Up: It's a common sign. If you notice ice forming on the evaporator coil, it could be due to high moisture levels. Unusual Noises: Listen to your refrigeration system. If it's making strange noises, it may have excess moisture.
Dry mode is specifically designed to lower indoor humidity levels. This feature is particularly helpful in humid weather, where the air feels sticky, but temperatures aren't high enough to warrant full cooling.
