Air Ducts Explained: Understanding The Role Air Ducts Play In Your Home

A house’s air duct is basically a tube which connects the HVAC system into a ventilated system. The air conditioning systems pull in air through the vents, then either heat or cool the air.

The cooling and heating air then circulates through ductwork or through air vents to heat and cool the room. Many people compare air duct systems and lung systems because they are passed through. The air duct is similar to the arterial system that runs through homes.

As long as our arterial walls are clean and our bodies have enough nutrients to function properly and organ functioning will continue.

Hot & cold spots

Obviously it is an indicator of a leakage of air. Most people have experienced this before. When a person walks in to their room they are too hot. Or on a flight they are much cooler, a little over 3 degrees below. Usually, you will need to test with an ultrasound device for this to happen.

When the problem is clear the HVAC technician can be called. They will find the cause, create and implement the planned actions. Find out about fixing cold spots and heat here.

Supply Ducts

The supply ducts circulate air into areas within the home. The ventilation vent has a damper for control of air flows called the registers. Supply registers may be installed close to doors or windows to help counteract heat loss.

Two supply registers are available in larger rooms to distribute air conditioning evenly. Okay, this covers the fundamentals of airflow. What happens if air vents do not meet standards?

Utility bills are high

It is possible for your piping to leak as much as 30 percent from duct lines. When conditioned air leaks or heated air gets sucked into an underinsulated duct, you pay utility costs. It may not seem that scary, but it may surprise you. In the end, you might discover that your house uses far more electricity than any other home you have.

Return Ducts

Despite common belief, HVAC systems are airborne inside buildings. Air from the living spaces is then returned to the HVAC system and fed to the furnaces and air handlers. A return vent is generally larger than a supply vent and is known as a grilled vent. In most HVAC systems, filters are located inside the return piping.

Little or no air flow from supply vents

It’s easier to verify the supply opening using paper. The paper bends so there’s nothing blocking airflow. Unless it was your luck it will just need to be re-opened. If this does not work, you might have to hire a professional HVAC technician for assistance.

Loud noise

Why are HVAC units making noise when they run? That’s true, but it doesn’t irritate you. The air duct may have broken loose, disassembled or deteriorated or the air duct is broken or cracked. Do you want this to be ignored?
