Similar to the human body, your HVAC system “inhales” and “exhales” the air around your home.  For your furnace to run efficiently and your home to heat evenly, this airflow must be in balance.  In other words, the amount of air that your furnace “breathes in” must equal the amount of air it “breathes out.”

Cold air returns are what allow your furnace to “inhale” your home’s air.  These registers are typically located low to the ground in different areas around your home to capture the cold air that sinks to the floor.  When warm air is delivered to a room, the existing cold air in that room is pushed into the cold air and returns.  Once inside your cold air returns, that air travels through your ductwork back to your furnace where it is filtered, heated, and sent back to warm your home.


Maximize Performance

Don’t block your cold air returns.  To allow for proper airflow, the space around your cold air returns needs to be clear.  If you have furniture, TVs, or other household items blocking your registers, it can prevent your cold air returns from doing their job.

Add more returns if needed.  Unfortunately, many homes were designed without the proper amount of air returns.  Some common symptoms of this include stuffy rooms, uneven heating, high energy bills, and unbalanced pressure.  If you suspect that you don’t have enough cold air returns in your home, East Coast Mechanical can analyze your home’s airflow and make improvements to your ductwork design to correct the problem.


Air conditioners and cold air return vents

Air return vents are essential to your HVAC system.  They are what pull air from the home, return it to the system, filter it, and help maintain comfortable temperatures throughout your house.  They also help remove excess moisture from the air, thus preventing your home from feeling muggy or dank.  If you have any questions about a cold air return, or if you’d like a heating system serviced or installed in your home, contact us.
