Usually it's the evaporator (in dash) that can get plugged from not changing you cabin air filter if so equipped or by other crud floating around in the vent system. Might alos be the blend door or blower motor ploblem. I've even found mouse nests in ducting that's plugged the system.
First of all, the component you mean is called the evaporator, the a.c's equivalent to the heat's heater core . Very unlikely it would or could become that clogged , mouse nest maybe, but even then your blower motor would still push a flow of air., though reduced. what is your vehicle's problem? If you can hear your blower motor running at selected speeds and nothing comes out,the fan or"squirrel cage" may have come off (rare) or the duct work is not operating correctly (kinda rare).
Air not coming through your vents can be caused by several issues, including a clogged air filter, which restricts airflow, or blocked ductwork due to debris or obstructions. Another possibility is a malfunctioning blower motor or issues with the HVAC system itself, such as a broken fan or thermostat problems. Additionally, closed or sealed vents can prevent air from circulating effectively. Regular maintenance can help prevent these issues.
A common cause of a frozen AC condenser is restricted airflow due to dirty air filters or blocked vents. Another cause can be low refrigerant levels. To solve this issue, you can clean or replace the air filters, clear any obstructions from vents, and have a professional check and refill the refrigerant levels if needed.
The potential causes of a musty smell in vents include mold or mildew growth, moisture buildup, or a clogged air filter. To effectively eliminate the smell, you can clean the vents and ducts, replace the air filter, and use a disinfectant or deodorizer specifically designed for HVAC systems. It is also recommended to address any underlying moisture issues to prevent the smell from returning.
Routine air vent cleaning saves homeowners money by improving the flow of air through the vent. When vents get clogged, the air has a harder time pushing through the vents, which causes energy bills to rise.
If the static vents become clogged, the airspeed indicator, altimeter, and vertical speed indicator will become inoperative. These instruments rely on static pressure to provide accurate readings, so any blockage in the static vents will disrupt their functioning.

The clicking sound from the air vents when the heat is turned on could be caused by a problem with the blend door actuator or a buildup of debris in the vents.
Check for the drain hose or pipe in your unit so that it is not clogged. Through the ac process water is collected and thus needs to come out. If the drain is clogged water will be trapped and the blower will pick it up and send it through the vents.
Potential causes of a furnace overheating issue can include a clogged air filter, blocked vents, malfunctioning thermostat, or a faulty limit switch. Solutions may involve replacing the air filter, clearing vents, recalibrating the thermostat, or repairing/replacing the limit switch. Regular maintenance and professional inspection can help prevent overheating issues.
The potential causes of a musty smell in AC vents include mold or mildew growth due to moisture buildup, a clogged air filter, or a dirty evaporator coil. To resolve this issue, you can try cleaning or replacing the air filter, cleaning the evaporator coil, and using a mold and mildew cleaner to eliminate any growth in the vents. It is also recommended to schedule regular maintenance for your AC system to prevent future musty smells.
If the AC blower is weak and air is blowing from the floor vents, it may indicate a problem with the system's airflow. Possible causes include a clogged air filter, obstructed ductwork, or an issue with the blower motor itself. Check and replace the air filter if needed, and ensure that vents are open and unobstructed. If problems persist, it may be best to consult a professional HVAC technician for further diagnosis.
