The ductwork in your home is designed to provide ample heated or cooled air to every corner of the house while removing old air and returning it to the air handler to be cooled or heated. The system is highly efficient, but over time the ductwork can develop cracks and leaks that cause a drop–off in that efficiency and can subsequently cost you money.

Our technicians are EPA and NATE certified to provide expert duct testing and maintenance services that will ensure optimal performance for your entire home heating and cooling system. Whether you just bought a new home or are having your existing ductwork upgraded, contact us today to learn more about duct testing.


Your ductwork is designed to provide and remove air from each room of your home. Supply ducts carry air from your air handler and return ducts take the old air back. So, for every cubic foot of air that is conditioned and distributed in your home, it is moved throughout your entire house twice. As a result, your ductwork undergoes some heavy wear and tear. Over time, that wear and tear can result in damage to your ductwork.

Common problems in ductwork include inadequate seals, poor connections, broken joints or other issues that allow air to escape in transit. Most ductwork already accounts for a 30% heating and cooling loss, just in transit. Add in a small leak, and that number can increase substantially, greatly increasing what you pay on your energy bill each month.

Duct testing allows us to quickly check and determine where in your ductwork these problems are developing, so they can be fixed rapidly. To test the seal on your ductwork, we close all registers and vents and then pressurize the system, taking measurements where air escapes and noting it for future repair. This process can be performed in a single day and gives us an accurate idea of what changes and repairs are needed to get your ductwork back to optimal operation.


If you are concerned that your ductwork is not working properly either because of increased energy bills or because your home is not as comfortable as it once was, call IERNA’s Heating & Cooling today. We will visit your home and provide a free estimate for the process of testing your ducts.

Our duct testing technicians have years of experience identifying potential problems and ensuring they are properly contained, so you can enjoy the comfort of your home and a low energy bill.
