What can be the cause of low air pressure from the air duct for your AC unit?

Dirty filter, dirty coil, closed damper, or duct has come loose from main trunk line.
Rats will sometimes nest in air ducts and may chew holes through the ducts, especially the insulated plastic ducts. That's the worst case.

What cause circular motion of air in pressure centers?
the Coriolis effect
Is the unit of measure for atmospheric pressure most commonly found on weather maps?
In weather maps, atmospheric pressure is measured in millibars. Standard atmospheric pressure is 1013.2 millibars at sea level. Air pressure varies depending on temperature and air density.
Why doesn't a closed paper bag collapse under the weight of earth's atmosphere?
The bag does not collapse because the air pressure acting on the inside of the bag is equal to the air pressure outside the bag (There are the same number of air molecules per unit volume inside the bag as outside). However if you had filled the bag with air at high altitude where the air pressure is lower, then sealed it and brought the bag down to sea level you would find that the higher external air pressure (there are fewer air molecules per unit volume inside the bag than outside) would begin to compress the bag down to a smaller volume. This in turn would compress the air inside the bag leading to an increase in its pressure. This decrease in volume will continue until the air inside the bag is compressed to the point where its pressure is equal to that of the external air pressure. For further information on this topic it may be worth searching for the term "Combined Gas Law" which will explain the relation between pressure, temperature and volume.
Compare air pressure on earth to air pressure on the moon?
The moon has no air pressure because the moon has no air.
What do air molecules do when they bounce off objects?
The impacts are what cause air pressure. After collision, the air molecule moves away in a straight line until it hits something else.
Can a portable ac cause a vacumn in a garage that makes the waterheater pilot to go out when the wind is strong outside?
It could depending on how it is installed. Portable air conditioners usually have a duct to outside for the removal of heat. The blower connected to the duct acts like an exhaust fan removing air from the interior causing a negative pressure. Some portable air conditioning units have the ability to use outside air as a means of making up the air that is being removed to prevent negative pressures (one duct from outside feeding air to the unit, one duct to outside from the unit). Proper makeup air must be provided to ensure a neutral pressure in the space. Caution: Not correcting a pressure differential can cause the water heater flue gases to backdraft into the interior space and cause carbon monoxide poisoning. A very dangerous and possibly fatal condition.
What type of duct would you fit on a warm air unit?
a se duct and a u duct
Air conditioning unit is not cooling after freon was put in?
Several things could cause this. There could be a leak in the pressure system that is allowing freon to escape. The compressor could be failing to generate enough pressure to drop the gas temperature. There could be a hole in the duct that allows colder air to escape before it reaches the vent. It could also be that the duct is poorly insulated and the air is rewarmed before it reaches you.
Can you overload on freon in your central air unit?
overcharging a central air unit system with refrigerant(freon) will cause the head pressure to be?
What size duct for cold air return for 3 ton unit?
A 16" round flex duct will accommodate up to a 3.5 ton unit
Who can suggest a reputable air duct cleaning service?
If the air isn't coming out as much, you might want to have the air unit looked at first. If it's not the unit, then it probably is the ducts. Contact the NADCA (National Air Duct Cleaners Association), they give a complete list of qualified air duct cleaning contractors in your area.
What would cause a vibration noise in air return duct?
apples
What would cause hot air to come out of your vents when your AC unit is not on if your house was built in 1925?
Check your duct work in your attic. Heat from attic could be coming in through a broken connection or hole in duct work, especially in a house that old.
Is gas particles in the air pressure?
Yes it Does Cause air Press it does cause air pressure.
What is the air pressure?
air pressure is the firce exerted by moving air moleculesAir pressure is the air around you. Air pressure can pushing every where so the air from the top only dosent squish you into a pancake. Pressure is defined as force per unit area. The standard unit for pressure is the Pascal, which is a Newton per square meter.
What is the bluduct?
A blue duct is a type of air conditioner that has continuous air flow. It is called a blue duct system because the unit can circulate air into a room evenly. It can do this without freezing on top like other air conditioners would.
Which is the standard unit of air pressure?
millibars
