To keep a comfortable temperature in your home all year round, it is very important that your duct work is in good condition. Normally, the duct work will last for many years. However, over time, metal duct work may begin to rust through, and plastic duct work may begin to crack. If you know what signs to look for, you can have your duct work repaired or replaced as soon as possible. These are some common signs that it is time to repair or replace your duct work.
Dirty, Dusty Registers
If an unusually large amount of dirt and dust is collecting around your vent registers, this is a sign that the duct work may have breaks or cracks in it. When the ducts are cracked or broken, dirt and dust that is under your home can blow in when your heat or air conditioning is on.
It is normal for a small amount of dust to occasionally get around the registers, but an excessive amount will only be visible if your ducts are not in good working condition.
Inadequate Heating or Cooling of Your Home
If your home is not as warm or cool as it should be when you have your thermostat set on your usual temperature, this can mean there is a problem in the duct work. If the duct work is cracked, some of the warm or cool air will escape through the cracks and go out under your home.
If this problem occurs, it is very important to have the duct work repaired or replaced as quickly as possible. Even a small crack can cause your heating or cooling bill to skyrocket if some of the heat or cool air is escaping through the cracks.
Mold Around the Registers
Another sign of cracked or broken duct work is visible mold that is growing on or around the vent registers. This problem occurs more frequently during summer than winter. This is a sign that humidity that is under your home is seeping through the duct work and causing mold to grow on your vents.
Visible Tears or Cracks
Anytime you can see visible tears or cracks in the duct work, it is time to have it repaired or replaced. Even small pinhole tears can lead to an extremely expensive heating or cooling bill if left in this condition.
To make sure your duct work is in proper working condition, it is a good idea to have a professional inspection done at least once a year. During early fall, while you are not using the heating or air conditioning system, have a licensed inspector check out all the duct work to ensure there are no visible damages.
