how can i test my air conditioning ducts for leaks

When your HVAC or cooling system is able to cool air, it will need to traverse through your ductwork before you can benefit from it in your living spaces. Duct leaks deprive homes of comfort in the home and cause HVAC systems to use more energy to keep ideal indoor temperatures. Learn to test your the ducts for leaks, and then eliminate the inefficiencies of your ducts at home.

Leaks in the Duct and Energy Loss

Duct systems must be tightly sealed to keep conditioned air in place and the energy it holds. Insecure connections, gaps broken duct sections, damaged ducts and duct runs that have been disconnected let the conditioned air out of the duct system prior to reaching your living areas in the indoors which wastes energy.

On average 25% of air loss is due to leaks. That is, one-fourth of the conditioned air isn’t getting delivered to rooms of your home. This is in line with air duct inefficiencies throughout the United States. The average home is losing 20-30% of its HVAC energy due to leaks in the ducts, which can result in high costs for utility usage.

How do you test Air Ducts for leaks

The process of testing ducts for leaks requires expert methods that provide the most precise analysis. This procedure makes use of special equipment that is connected with the system of ducts and airflow measurements are taken to determine whether leaks are present.

In addition to the expert test, you can also do couple of things that homeowners can do to detect leaks in their ducts.

  • Check all ducts you can access. Take a step into your attic basement or crawlspace, and examine the ducts visible. Examine each section of duct and connective tissue for obvious gapping, tears and disconnections. Also, look for regions of the ducts with taped ducts. This could indicate that leaks in the ducts have probably been patched prior to. It is essential to examine these areas, as well since the duct tape isn’t an appropriate material to seal leaks, and leaks could be there.
  • Switch on your HVAC and then return to the places where the ductwork is easily accessible. Verify the connections between the sections of duct by place your hand on the metal. If you feel the air on your palm then the connection is not secure and there’s the possibility of air leakage. A typical place to leak is in the duct joints.
  • When the HVAC system turned on, move an incense stick , or fume pen through the ducts, and then watch for any movement within the ducts. This indicates that the air is leaving the ducts.

If you discover any spots that show obvious or suspect leaks in ducts then mark them with an arrow over the duct using grease pencils so that you can pinpoint the source of the leak. After you have inspected for leaks, it is in a position to go back to these problematic areas and seal the area to stop the leak.

What is the other reason for Ductwork Inefficiencies?

In addition to air loss that can be found due to leaks, other factors can cause the loss of energy and poor efficiency of the ducts in your home.

Ducts that are dirty

Airborne dirt and dirt build up in the ductwork of your home as air circulates throughout the home. The debris can cause obstructions in airflow. Even if the buildup doesn’t completely block airflow it can still hinder free air circulation through the air ducts.

The answer to dirty ducts is to have professional duct cleaning. This clears the ducts of debris and dirt. Clean ducts let air freely flow through them for greater HVAC efficiency. Furthermore, with fewer contaminants getting into the air supply, you can benefit from a better Redlands the quality of your indoor air.

Uninsulated ducts

Ductwork is typically found in parts of your home which aren’t heated or cool. In these regions the temperature difference between the air around and the ductwork is significant. A majority of the ductwork of homes goes through the attic which can see temperatures rise up to 130 degrees. When compared to the cooler air of 70 degrees that is circulating through the ducts which is a 60 degree temperature difference! This can affect how hot the air conditioned through your home, and your HVAC system will have to be more efficient to compensate for the reduction.

Insulate your ductwork, specifically the ducts that go through areas that are not conditioned. Insulation can help the air that circulates retain its cooling and heating energy, which means you can get the benefits within your living space. Ducts in crawl spaces, attics as well as garages with unfinished basements can benefit from the insulation.
