The Most Common Causes of HVAC Airflow Problems

Airflow issues are among the most common types of problems that occur in HVAC systems. But what causes those problems, and what steps can you take to find a solution?

Here’s a quick overview of some of the top causes of HVAC airflow problems in St. George, UT:

• Blocked vents and registers: The problem may be as simple as there being items placed in front of the vents and registers in your home, which prevents the air from flowing into your space. If you move furniture and other items away from those vents, this could be all you need to resolve the issue.
• Dirty filters: You should change your air conditioner’s filter at least a few times a year, and as frequently as once a month depending on the manufacturer’s recommendations and the conditions affecting the air quality in your home. A filter that gets clogged up with too much debris will impede airflow.
• Obstructed condenser: The condensing unit is usually located outside for an air conditioner, and it could become affected by a buildup of leaves, debris and vegetation. If the system is located in a mechanical room, other equipment or items in storage may cause the obstruction. Removing the obstruction may resolve the issue.
• Thermostat problems: If the thermostat is faulty or has a worn-down battery, you might have problems with HVAC operation.
• Low refrigerant: Among the most common problems with HVAC systems is low refrigerant levels. This is especially likely to occur in systems that are older or not properly maintained. When leaks form, you’ll see problems with achieving cool air and proper airflow. Make sure you schedule regular appointments with an HVAC contractor who can inspect your system and find issues before they turn into larger problems and leaks.
• Oversized units: Some people accidentally purchase air conditioning units that are actually too large for their home. If you have a unit with a capacity that’s too large for your home, it will cycle on and off frequently and never run long enough to actually cool your home and remove humidity.
• Ductwork problems: If you have any ductwork that is blocked off or leaking air, this could be the issue behind your airflow problem. Ductwork can develop holes or cracks, creating opportunities for air to leak out of the system. You could have your ducts inspected and sealed up if there are any air leaks. This could go a long way toward improving the efficiency of your entire system.
• Fan problems: HVAC systems have blower fans that are tasked with pushing the air through the ducts and into the rooms throughout your home. If your blower motor is having problems, this could result in lower levels of HVAC airflow, reducing overall performance and making it difficult for you to maintain comfortable temperatures in your home.

These are just a few examples of some of the most common HVAC airflow problems and the potential causes behind them in St. George, UT. For more information, we encourage you to contact Calaway Heating & Air Conditioning today.
