Signs It’s Time for a Duct Test

duct-sealingIf you have a central AC, a furnace, or a traditional heat pump, then you know that your HVAC system relies on ducts. In fact, for these systems, the ductwork does half of the work. The ducts are a series of passages that must be kept at a certain tightness in order to efficiently transfer air from the HVAC unit and into the rooms of the home.

What many homeowners don’t realize is that the ductwork is prone to falling into disrepair. This can lead to leaks, which might end up losing you nearly 30% of your energy. The best way to find out if you have a leak is by having the ducts tested by an expert, which is a service you can schedule if you notice any of these signs:

Lowered Efficiency

A duct leak isn’t something that will make itself obvious. They don’t make noise and they don’t drastically alter the HVAC system’s operation. Many homeowners go a long time before they ever realize they have an issue with the ducts.

What finally makes the leak known is through a noticed increase in the utility bill. Even then, many might mistake this increase as a reflection of their own usage habits. This is where it can help substantially to have a smart thermostat in place, since they can help track your usage more accurately.

Since a leak will drain some of the heated or cooled air out of your ducts, it will take more energy to get your home set to the desired temperature. This extra work is the reason your utility bill rises.

Lack of Airflow

If your recent bill has got you suspicious about leaks, the next sign can come from observing a lack of airflow from the vents. Simply test all of the air registers in the home by placing your hand in front. If you notice significantly diminished air from one or some of the vents, that could be an indication that there’s a leak somewhere in the ductwork system.

You may have also noticed that some areas of the home are stubborn, refusing to change their temperature. These areas are called hot and cold spots. While these spots can be due to many things, duct leaks is one possibility. An indoor air quality expert can help you find out for sure.

Age of Your HVAC System

The average duct system has a lifespan of about 20 years. Many homes may already have ductwork installed in them, so essentially, the ducts are going to be the same age as the home. Unless you moved into a brand-new home, there’s a possibility that you’re living with some very old ducts.

Despite the generous life expectancy of ducts, we recommend having them checked with regular maintenance annually. There are a few reasons that ducts can start to deteriorate or disconnect before their time:

  • Pests have been known to chew holes through flexible ductwork.
  • A poor installation—one that was done with low-quality materials—may be degrading.
  • Ducts may have become knocked loose while working in the attic.
