how to tell airflow direction on hvac

So how can you tell which way air flows in an AC unit. Pull the old filter out and discard it.

Downflow furnaces are sometimes called counterflow or downdraft furnaces.

. In this video I explain how to know for sure that you understand which way the air flows. Remove the doors of the furnace. In other words the air travels from the tail of the arrow toward its point.

In addition to clean air filters also protect your HVAC system from debris and dirt buildup. When you are replacing your furnace air filter it is critical to determine the airflow pattern of your filter. To begin with you can refer to the printed direction to adjust arrow points on the product manual and side of the filter frame.

Always make sure the arrow is facing towards the furnace. Every furnace has an air inlet and an air outlet. Find the arrow on the frame.

The Airflow Direction Test and visualization can be performed by the following methods. Switch on the blower by selecting the fan options of the thermostat and make it On after removal of the air filter. As a homeowner you can perform this simple HVAC repair on your own.

The airflow direction of your air handler is also indicated with arrows on the outside of the filter housing. The airflow arrow should point towards the furnaceblower motor to collect harmful particles before it reaches the furnaces equipment. All furnace filters or HVAC air filters have arrows around the edge that point in the airflows direction in your air handler.

Look for the arrow points on the air filter. A horizontal furnace lies on its side pulling cool air from one side and pushing warm air out of the other. The inlet is referred as the return air and the outlet is the supply air or conditioned air into the home.

The direction of the air flow is from the return air to the supply side. I see air filters all that time that have been installed backwards. You can follow them according to the wind direction.

Another way to determine the direction of airflow is to look for an arrow in or around the filter slot. Airflow comes in from the bottom of the air handler or furnace and flows out the top of the unit. The arrow must always face toward the furnace and away from the return duct.

That direction is from the cold air to the hot air duct as the air. The test is carried out by observation or imaging of the behavior of tracer particles illuminated by high intensity light sources and provides information about the direction and uniformity of airflow in installations. You should always install the filter with the arrows pointing in the airflow direction.

The arrow must face toward the furnace and away from the return duct that pulls the air in need of heating or cooling. Changing your air filter is one of the most important steps of HVAC maintenance. The easiest way to tell which way air flows in an AC unit is by holding a strip of paper where the filter goes.

If you are looking at a furnace filter find the arrow that indicates the proper air flow direction. If the old filter has already been removed you can use these tips as a guide when replacing furnace filter. You measure the velocity at a points in the duct and find the average velocity in the exhaust duct is 400 fpm.

Slide it in and you are all set. This type of unit is most common when the unit is installed in a closet. The tracer particles can be generated.

On the new filter find the arrow indicating the proper airflow direction. This type of system is most common in basement installations. First of all your hvac units placement can give you a good idea of the airflow direction.

The direction of the airflow is from the blower section to the burner or elements. Position the airflow arrow so that it points in the direction the air is flowing. Downflow Airflow comes in at the top of the air handler or furnace and flows out the bottom of the unit.

Change the direction of airflow within a duct line by turning the valve or lever on the manual control. Its important to determine the airflow direction for a furnace filter so that it works properly and installation simply requires setting up the filter to a. Align the vane wheel with the direction of airflow in order to get the most accurate readings.

How to tell airflow direction on hvac. The arrow will let you know that you have the direction of the airflow correct. The easiest way in determining which way the furnace filter direction is to refer to the old filter before removing it and installing the new one in the same way.

A downflow furnace is typically installed when the ductwork is located below the furnace. You will occasionally see a distinction between a horizontal. The airflow pattern marks the direction in which air moves in and out of your system and furnace filters work.

Turn on the AC unit and watch the direction it blows.
