Unless the central air is specifically built to work as a dehumidifier, it won’t be effective in humidity control. The main job of central air is to maintain the temperature of the environment. It takes the air in, passes it through an evaporator and condenser, which in turn reduces the air temperature.In the presence of the humidity, the space feels hotter than it actual is. This makes  the air conditioner need to run longer, just to cool everything down. Unfortunately, It has to work harder to compensate for the humidity.

• It can be controlled remotely, making controlling and operating it easy and user friendly
• Operation is noise-free
• Not visible from the living area because it is connected to HVAC duct work
• Has a long life span and few maintenance costs
•  Replacements are easily available 
• Long warranties are usually offered 
• Prevents mold 
• Keeps dust mites under control
• Helps to alleviate asthma and allergies 
• Keeps you comfortable 
• Protects your home from rust
• Helps to prevent wood from warping, cracking or splitting due to high levels of moisture
• Helps to prevent wall paper from pealing from excess humidity

Whole-house dehumidifiers are usually installed to operate in conjunction with the house’s central heating and cooling system. The inlet pipe of dehumidifiers connects to the return ductwork. This draws the air in, cools it to below the dew point, then liquefies the moisture in the air turning it into water droplets. These drops of water fall into a pan, then drain.

Dry air on the other hand passes through the warm coil. This increases the air temperature. This air with the desired temperature and humidity level is then sent out to the rooms in your home. Pretty cool, right?

With a home dehumidifier, there’s a moisture sensor that continuously observes the humidity level in the air. Whenever an increase in the humidity is detected, it automatically turns on the dehumidifier.

To select whether to buy a whole-house dehumidifier or portable dehumidifier is right for you, an HVAC specialist can assess the needs of your environment, family, and home.It’s important to consider the number of rooms, size of the house, and humidity level. If there is only one room or area which needs humidity control, then, of course, a portable dehumidifier is the best choice considering that the area is not much larger. However, for effective humidity control in an entire house with multiple rooms, it is always recommended to install a whole-house dehumidifier for easier use. 

Finally, the operation of a whole house dehumidifier differs based on how it is installed and can be the governing factor between the performances of two similar whole house dehumidifier.

In a non-ventilating configuration, air from a room is taken in, passed through dehumidifiers to extract the moisture from the air, and then that same air is sent back to the rooms.

On the other hand, the ventilating configuration keeps replacing the air from the rooms with fresh air from outside. It takes the fresh air from outside, filters it, extracts the moisture, then sends it to the rooms. This creates consistent circulation.

A ventilating configuration has an advantage over non-ventilating as it provides the building with ventilated air. Clean and dry air is consistently cycled in and out of the house, which gives, many benefits including avoiding mold growth. Adding new fresh air and removing existing air helps eliminate moisture produced inside, smoke, cooking odors, and other indoor pollutants. Good ventilation saves from allergies and asthma.

The initial purchase of a portable dehumidifier is less expensive as compared to the whole house dehumidifiers.It does not require any professional installation to start using it. You buy it, place it in the place you want it to you, and plug it in for immediate use.As it is lightweight and size and needs no prior installation for use, you can easily take it to any place or area.They come with digital controls to control their operations easily.

Unfortunately,

• It can only be used only in one room or area at a time. Therefore, if you have more rooms in use at a time, you need to buy multiple units.
• There is a bucket to collect the water coming from the condensation of moisture in the air. You need to empty this bucket from time to time.
• These units are noisier as these are placed in the rooms you live in.
• Most portable dehumidifiers do not disclose a CFM rating, which is a very important part of the dehumidification equation. Smaller dehumidifiers with low CFM ratings will not be able to cycle enough air through the unit to adequately affect the humidity levels in larger areas.
• Portable dehumidifiers have a shorter lifetime as compared to the whole house dehumidifiers and usually, shorter warranties are offered for such units.
