∙ 14y ago
Black dust coming from AC vents can be due to several reasons, such as a dirty air filter, mold growth in the ductwork, or accumulated dust and debris in the ventilation system. It is essential to have the system inspected and cleaned by a professional to improve indoor air quality and prevent potential health issues.

Why is condensation forming on your ac ceiling vents?
Condensation forms on AC ceiling vents when warm air from the room comes into contact with the cold surface of the vent. This temperature difference causes the moisture in the air to condense and accumulate on the vent, similar to how dew forms on grass in the morning. It's a sign that the AC system may need inspection or maintenance to ensure proper operation.
Why is the downstairs vents not blowing on central ac but the upstairs vents are?
There could be a blockage or leak in the ducts leading to the downstairs vents, causing poor airflow. It's also possible that the damper controlling airflow to the downstairs vents is closed or malfunctioning. Check these areas for issues and consider contacting an HVAC technician for assistance.
Why is window ac losing cooling efficiency. Indoor air is 5 degrees warmer than desired temperature - AC is set at 22C temp is 26.?
There could be several reasons for the decreased cooling efficiency of a window air conditioner, including dirty air filters, blocked vents, low refrigerant levels, or a malfunctioning thermostat. Ensure that the air filter is clean, the vents are unobstructed, and that the thermostat is functioning properly. If the issue persists, it may require professional inspection and maintenance.
Does turning thermostat temperature to higher temp make the air coming out of vents hotter on central ac with heat coil. Significant other swears it does and trying to settle dispute?
Turning the thermostat to a higher temperature does not make the air coming out of the vents hotter on a central AC with a heat coil. The temperature setting on the thermostat simply tells the system when to stop cooling or heating, but it doesn't affect the actual temperature of the air being produced. The heat coil or furnace is responsible for heating the air, not the thermostat setting.
Why does the home split ac blow out water droplets?
This happens when the condensate drainage system is clogged or when there is excess humidity in the air. As the air conditioner cools the warm air, it removes moisture from it, which can condense into water droplets. If the drainage system is not working properly, the water may collect and be blown out of the vents along with the air.

What is causing the air to come through the defroster vents and not the AC vents in a 1995 Ford Mustang GT when the AC or vent knob is turned on?
I am sorry, I am not technical on this stuff, but we had the same problem on our 95 Mustang GT. We had to take it into the dealer and the problem was that one of the hoses had come loose, so it was not blowing enough air pressure to force the vents open.

How do you change the air conditioning vents to the correct position?
AC VENTS are in the correct position if they are open and free flowing. Some systems have a heat and an AC position for the vents. The AC position is so the cool air discharges from the vents higher on the walls or from the dash rather than floor or windshield in a car.
How do you fix your ac to blow in the correct vents and not just the defroster?
