Installing the right heating system in a room is important, and not just for the comfort that a pleasant temperature brings. Heating a room can help remove humidity, but only if it is also well ventilated. Poor ventilation leads to increased humidity, which can promote mold growth in the room, from the walls to the carpets. The secret is to ensure even airflow through a room as it heats up, keeping the temperature constant but preventing the buildup of humidity. The volume of air that needs to circulate in the room is measured in cubic feet per minute (CFM) and determining the correct volume is key to a successful heating system.

 Sone

Sone is an internationally recognized measure of sound. This measurement is verified in a neutral environment such as a laboratory and reflects what an average person can hear. If you double the number of sones, you double the volume of the noise (i.e. if a first device gives two sones and a second gives four, then the second device is twice as loud as the first).

A sone is the noise a quiet refrigerator would make in a quiet kitchen.

Cubic Feet Per Minute (CFM)

CFM stands for Exhaust Air Flow in Cubic Feet Per Minute. Cubic feet per minute (CFM) is a measure of airflow volume, determined by the number of cubic feet of air passing a stationary point in one minute. The higher the CFM number, the greater the exhaust airflow. Naturally, larger homes circulate more air, so they will have a higher CFM.

Why is CFM important?

Having an accurate estimate of your home’s CFM is key to choosing an HVAC system with the right capacity for your space and needs. Too much or too little airflow can negatively affect your system’s performance and even damage your components.

 Determining the Proper Capacity

A qualified HVAC dealer calculates your home’s CFM and will consider various factors such as the number of windows you have, the type of climate you live in, and even your family’s temperature preferences to determine the appropriate capacity of the system. Experienced professionals will be able to recommend a home comfort system that can not only improve your family’s comfort, but also help reduce your electricity bills.

Warning

Balancing a heating system can be a complicated process. Weather conditions are constantly changing and the heating system must react accordingly. If in doubt, consult a qualified heating contractor before adjusting the system. The professional team of the Rousso Group is made up of engineers who will be able to help you in this process.
