HVAC airflow problems can lead to hot and cold spots in your Childersburg, Alabama, home. They can also drive up your utility costs. You can save money on your bills and avoid having to replace a broken HVAC system in the future by scheduling regular maintenance. If your home is experiencing an HVAC airflow problem, one of these seven issues is the likely cause, but luckily maintenance can help prevent them.

Clogged or Dirty Filters

Do you remember the last time you changed your AC system’s filters? Clogged or dirty filters can lead to airflow issues with your air conditioning system. The filter removes debris and dust from the air circulating in your home and keeps it out of your ducts and other HVAC equipment. But when the filter gets clogged or full of dust, it can impede the flow of air, forcing the system to work harder and leading to warm and cold spots around the house. Make sure to change your AC filter according to the manufacturer’s instructions and how heavily you use your system.

Blocked Vents and Registers

Blocked vents and registers could also be causing problems with your HVAC system’s airflow. Make sure all your air vents are open. Also check to be sure a piece of furniture, a rug, or another obstruction isn’t covering or blocking a vent or register.

Blocked or Leaky Ducts

If dust or other debris make it through your AC filter, it can accumulate inside your ductwork. This is especially problematic if your ductwork is already too small for your HVAC capacity. It’s also possible for birds, insects, or rodents to get into HVAC ducts and build nests or bring in debris that blocks the ductwork.

Additionally, ductwork walls can develop cracks where air leaks out. Both leaks and blockages can lead to reduced airflow. To make sure air is circulating properly through your HVAC system, have an experienced technician inspect your ductwork. Fixing blocked or leaky ducts can help you save on your energy bills and reduce your home’s environmental impact.

Mechanical Issues

Wear and tear on the many mechanical pieces found in your HVAC system, including motors, belts, or bearings, can also cause problems. Over time, even normal wear can lead to poor airflow, overcooling, or overheating. Lack of maintenance will compound the problem, likely leading to greater damage over time — and greater costs associated with fixing the problem.

Obstructed Condensing Unit

Each HVAC system has a condensing unit, which is the outdoor component of the system (it might also be located in a mechanical room). Leaves and other outdoor debris can accumulate around outdoor condensing units, and stored items or other equipment can obstruct those located in mechanical rooms. A blocked condensing unit can cause the system to overheat if there’s not enough airflow to the AC unit. Keep the area around your condensing unit free of debris to avoid HVAC airflow issues.

Improperly Sized or Installed Ductwork

Improperly sized ductwork for your HVAC system’s capacity can cause airflow problems. Ductwork can either be too small or too large for the AC system. Restricted airflow caused by too-small or improperly installed ductwork can keep the air from reaching its intended destination. On the other hand, ductwork that is too large can lead to a drop in pressure that causes a similar outcome.

Improperly sized or installed ductwork can, therefore, lead to unbalanced airflow, uneven heating and cooling, and, eventually, higher energy and maintenance costs.

Closed or Loose Dampers

The dampers are the small doors located inside your system’s branch ducts that adjust the flow of cool air. (Not all systems use dampers.)Dampers can get partially closed or come loose over time, leading to restricted airflow in parts of your house. A technician can check for this issue.
