Understanding Relative Humidity and Your Home HVAC System

A good home HVAC system regulates relative humidity around the clock.

Controlling Humidity Levels inside a Home

You have probably heard the term "relative humidity" somewhere before - your weatherman probably mentions it all the time, for instance. But do you know what relative humidity is, how it's measured, or what impact it can have on your body? Did you know, for instance, that the measure of the relative humidity in your home can make you feel hotter or cooler than you really should?

Keep reading to learn more about relative humidity and why it's important to control the humidity in your home with a fully equipped home HVAC system.

What is relative humidity?

Relative humidity is the measure of how much moisture is in the air relative to the maximum amount of moisture that the air can hold at the given temperature and pressure. Air that has 100% relative humidity is completely saturated with moisture and cannot hold any more water vapor.

How does relative humidity affect me?

Since the human body relies on sweat evaporation to cool down, and 100% relative humidity will not allow a person to sweat, we feel warmer in humid areas than arid places.

What is ideal relative humidity for my home?

Your home will feel most comfortable if relative humidity is kept between 35% and 45%.

Can I control the relative humidity in my home?

Absolutely - if you have the right equipment installed with your home HVAC system. If your home's relative humidity is too low, a humidifier will add moisture to your home's air supply to increase the relative humidity. If your home's relative humidity is too high, a de-humidifier can remove excess moisture from the air and reduce the relative humidity.

Why is it important to control my home's relative humidity?

Air that is too dry can cause physical problems like dry or chapped skin and lips, dry eyes, headaches, nosebleeds, and more. It can cause paint and wood furniture to dry out, chip, and crack. Air that is too moist encourages the growth of mold and bacteria - in addition to respiratory problems, mold and mildew can cause structural damage to your home, leading to costly repairs.
