Why Is No Warm or Cold Air Coming Out of Some of My Vents?
If the vent is open, and if it is properly connected to the ductwork, then the problem is probably an air intake vent. The fundamental principle of a central heating and air conditioning system is that room air is drawn into ducts where it moves to a central unit for heating and cooling. Then, it’s blown out other ducts and into your home from the air supply vents as warm or cool air. Eventually, the air is drawn back into the intake vents and the circulation cycle continues over and over. Along the way, the circulating air provides other benefits.
Filter Pollutants
As room air makes its way through air intake, ducts, heating or cooling, supply ducts and out the supply vents, it passes through a filter. The filter is your first defense in keeping harmful particles out of the air that you breathe.
There are other systems that can be installed to kill the germs that are circulating in your indoor air. The REME HALO is a highly recommended air purification system that you can install in ductwork, but it is not a replacement for the air filter. For clean air, there is no replacement for heating and cooling system air filters. Use a good filter and change it often. Once or twice a year is not enough. Use good filters, buy them in bulk, and change them frequently. The cleaner the filter, the cleaner the air in your home.
Maintain Air Pressure
Your HVAC heating and cooling system is a recirculating system. When warm or cool air comes out of the supply vents, an equal amount of air must go into the intake vents. Your home has been engineered for balanced airflow. If the intake vents are blocked or otherwise inadequate to balance the supply vents, the system will not work properly or efficiently. The heating and cooling system of your home demands balanced airflow. You may find that some are not heating and cooling as well as others.
If intake vents are blocked, your system still attempts to blow the same amount of air out of the supply vents. Pressure in the ducts will increase, causing the blower to work harder, which will increase your utility bills. Additionally, the pressure will cause ducts to leak, which will increase costs even more. Increased wear on your blower will eventually reduce the lifespan of your system.
It is important that you do not put furniture in front of air intake vents. Do not put rugs over them; do not close or obstruct them in any way. Nothing comes out of intake vents, but it is very important that unobstructed air be able to go into them.
