3 Reasons Why Your Furnace Might Be Giving You Reduced Air Flow
Posted on: 28 November 2022
There are various ways to tell your furnace has airflow issues. Typically, you will notice a system problem when your home becomes stuffier than usual and there are cold spots, despite cracking up the thermostat. Note that you should never ignore any furnace airflow issues, no matter how minor they seem. Instead, find a licensed technician to assess your systems and determine why you aren't getting as much air as you should. Here are the top three reasons why airflow issues occur.
The Air Ducts Have an Obstruction
The ducts carry the heated air you need to keep your space comfortable. Hence, if something obstructs them, the air will stop flowing through efficiently. Note that the air filters positioned where the duct start should filter dust particles, pollen, and other debris and prevent them from getting inside your home. However, they might not trap everything coming in at all times. Hence, the dirt that bypasses the system might eventually build up inside the ducts and create an obstruction that restricts airflow. Given this, consult a technician to assess and determine whether you have system blockages and clear them to restore proper airflow.
Less than Enough Return Vents
The return air vents absorb the warm air that the furnace produces and distribute it. So, if you do not have enough vents, your home will not get enough warm air from the system. More so, the heating unit will not get back the same volume of air it distributes into the rooms, hence the imbalance. In this case, a technician can assess your vents and help determine whether they are enough to keep the balance and air pressure between the room and the furnace. If not, they might recommend additional vents.
Holes in the Ducts
Holes are another common reason why you receive less air than you need. Note that openings inside the duct automatically mean some heated air will leak instead of getting to the designated rooms. So, if the air leaks into a different room beside where it should end up, the room will be hotter than it should be. That said, this is a problem that a technician can resolve by sealing parts of the system.
The best way to handle issues affecting your furnace is by getting an HVAC contractor to assess it. They can determine what is causing low airflow and the ideal way to distribute or resolve it.
