Temperatures are dropping. Snow has fallen, and the trees across campus are losing leaves. Winter is coming, and Joliet Junior College HVAC professor Juan Aguilar is ready to help you prepare for the Midwestern cold and stay warm indoors.

Check your furnace filter.

Make sure supply and return vents are clear.

Move furniture and other large objects that may obstruct the vents to allow for proper airflow.


Take care of the humidifier (if applicable).

Use a humidifier and thermostat accordingly.

A good recommendation is an indoor relative humidity of 35% with a thermostat setpoint of 68 degrees Fahrenheit during the winter.


Joliet Junior College's HVAC program sets students up for success in the commercial industry as a service technician, building service engineer, contractor and more. In addition, JJC HVAC students have the opportunity to put their skills to the test in volunteer work with Habitat for Humanity.
