Does air flow out of your vents with weak pressure and a foul odor? You might need to get the air ducts inspected to find out if they are in need of being repaired or replaced. Below, you will learn about a few of the things that can cause an HVAC system to have weak airflow and a foul odor.
Mold & Rodents
A common cause for foul odors to come out of HVAC vents is from mold growing in the air ducts. However, the odor from the mold is the least important thing that you should be worried out. It is possible that the mold is toxic, which can harm your health if the spores circulate in your house when the HVAC system is running. A contractor will be able to remove the mold to get rid of the odor and health risk. Rodents can also die inside of air ducts and cause a foul odor when air flows through ducts.
Air Leaks Out Due to Loose Fittings
Weak airflow from an HVAC system is sometimes the result of air duct fittings not being secure. Basically, the loose fittings create spaces in the ducts in which air can seep out. Before air flows into your rooms, a large portion of it can leak through the loose fittings. Getting the fittings tightened by an HVAC contractor might resolve the weak airflow problem.
A Large Accumulation of Dirt
Dirt is one of the main culprits that cause problems for an air duct system. It is natural for dirt to accumulate in the ducts, but it is a good idea to limit how much builds up on the metal ducts. As the dirt accumulates, it becomes harder for air to pass through the ducts. You then end up with an HVAC system that is not as energy efficient as it once was due to air not flowing out of vents at a high amount of pressure.
Rust Has Created Holes in the Ducts
Being that the air ducts are constructed of metal, it is only natural for rust to develop on them after they are in a house for numerous years. If rust is present, it is wise to ask a contractor to inspect the ducts to make sure there are no holes in them. If there aren't very many holes, they can possibly be sealed up so you can use the ducts a little longer. However, ducts that are covered in holes and rust should be replaced.
