Leaky Ductwork: The 5 Telltale Signs

Published on: August 9, 2012

Having ductwork that is free of leaks is a huge part of having an efficient air conditioning system. If there are leaks in your ductwork, it is important to have AC maintenance done immediately to fix them. Leaky ductwork can lead to poor air quality, increased power bills and trouble keeping your home cool. Here are five of the most common signs that your ducts need AC maintenance done to repair leaks.

Low Air Quality
When your air ducts have leaks, debris, pollen and other airborne particles from outside your home are able to enter your ductwork. Even if you have a high-quality air filtration system, the amount of detritus that enters your ducts from the outside is more than most filters can handle. As your air filters become overloaded, you may notice a drop in the air quality in your home and that you have to replace your air filters with increasing frequency.

Uneven Cooling
In addition to dust and other debris, when your air ducts are leaking, cool air that is generated by your air conditioning system is able to escape. Additionally, while cool air is leaving your home, it is often replaced by warm air, which can make rooms in your home stuffy and warm. Areas and rooms in your home that are closest to your air conditioning unit are likely to remain easy to cool, but rooms that are farther down the line will become difficult to keep comfortable.

Increasing Power Bills
Another side effect of your ductwork leaking and needing AC maintenance is continuously increasing power bills. As cool air escapes your home and is replaced by warm air, your air conditioner has to work harder to keep your home cool. Additionally, when debris builds up in your ducts, it can cause blockages which require your AC unit to work harder to blow air past them. This increased energy use leads to your power bills rising, even if it is not the middle of summer.

Increased AC Maintenance and Repairs
As your air conditioning system has to work harder and deal with increasing levels of debris, it can shorten the lifespan of your air conditioner. This often means ongoing AC maintenance and repairs. If you are consistently having to have repair technicians visit your home, you may have an undiagnosed duct problem.

Rooms That Are Always Dusty
If your ductwork has leaks in it and is letting in debris and dust from outside, you may discover that you have a hard time keeping your home clean. As your air filters become overloaded, dust and other airborne particles as blown out of your air vents. Even if you dust your home on a regular basis, leaking ducts can often cause dust to build up again rapidly.
