You are viewing the Nashville, TN location.
Your air conditioning system can experience “breathing problems.” Much of the AC’s successful operation at keeping your home cool is based on its ability to circulate air—drawing air from the house through return air ducts, cooling it, and then blowing it into supply air ducts to the room. If your AC struggles to do this, it will result in a lower volume of cooled air and less air sent to the rooms. Obviously, This Is Not Good when it comes to your comfort.
So you’ve got a “wheezing” AC on your hands. What’s causing it, and what can you do about it? Below, we’ll examine these questions about poor airflow from an AC and help you identify when you need AC repair in Nashville, TN.
Common Causes of AC Airflow Trouble
Dirty air filter: This is the first thing to check when you notice airflow is lower than normal. The air filter is located between the return air duct and the AC’s blower assembly, and it does the job of protecting the interior of the air conditioner from dust, lint, and other debris that will get sucked in with the air from the home. The filter will get dirty after 1–3 months and start to obstruct airflow. Change the filter if it’s dirty and then keep up a regular schedule of filter changes.
Blocked or closed vents: One common reason for reduced airflow is blocked or closed vents. Make sure all the supply and return vents in your home are open and unblocked by furniture, rugs, or curtains. Even partially closed vents can significantly reduce the efficiency of your AC system, leading to uneven cooling and increased strain on the system.
Blower assembly problems: The blower assembly is responsible for pushing the cooled air through the ducts and into your living spaces. If the blower motor or the fan is malfunctioning, it can result in weak airflow. Issues like a worn-out motor, loose fan blades, or accumulated dirt and debris on the blower components can all contribute to this problem. Regular maintenance can help identify and resolve these issues before they lead to more significant damage.
Duct leaks: Leaks in the ductwork can cause a significant drop in the amount of air reaching your rooms. This is because the cool air escapes through the gaps or holes in the ducts before it reaches its destination. To address this, it’s best to call professionals who can perform tests to locate the leaks and properly seal them. This not only improves airflow but also enhances overall AC efficiency.
Improperly Sized Ducts: Ducts that are too large or too small for your HVAC system can cause airflow issues. Ducts that are too small create high resistance, making it difficult for the air to flow through. On the other hand, ducts that are too large may not maintain enough pressure to move the air efficiently. If you suspect that your ductwork is not appropriately sized, a professional assessment is necessary.
