Anyone who lives in a hot climate region appreciates the instant relief that comes with having a properly functioning AC system. If you're looking to install a residential AC system to help you fight the summer heat, you should know that the system does much more than just keep you cool.

Read on to find out other important purposes that residential AC units serve in addition to providing home-cooling service.

Residential air conditioners provide humidity control. 

Most modern air conditioners don't just remove heat from your interior living environment — they also suck the moisture from the air to keep you feeling cool and comfortable on hot days. So, how does a residential AC unit remove humidity?

The unit has an evaporator coil that condenses water vapor present in the air. This is achieved by blowing the warmer air from your home over the coil. As the water vapor turns into a liquid, it is collected in a condensate pan located just beneath the coil and drained away from your home. This process is repeated with every air conditioning cycle.

High humidity makes it difficult to keep the environment inside your house cool and comfortable, because the moisture in the air holds up the heat, making hot weather hotter. It can also result in other problems such as foggy windows, mold and mildew odors, and clammy skin.

Residential air conditioners improve indoor air quality.

You should care about the quality of air inside your home because it directly affects the health of your family. The presence of contaminants in your indoor air can exacerbate the condition of family members with asthma or other respiratory conditions.

In addition to removing excess heat and humidity from your home, air conditioners play a critical part in improving the air quality inside your home. These space-cooling systems have air filters that help remove dust, pollen, pet dander, and other contaminants from the air. This ensures a supply of clean, cool air. 

AC air filters, however, aren't designed to last forever. They get clogged with dirt over time and will need to be replaced regularly as part of preventative AC maintenance. Fortunately, they're pretty cheap and easy to replace.
