The most common HVAC airflow problems


When everything is working as expected, it’s easy to take your HVAC for granted. During the summer, cool air is vital in the hot desert climate. Unfortunately, sometimes HVAC airflow problems can cause a unit to fail. Taking the time to maintain your HVAC system can help prolong the life of your unit and save you money in the long run.


Dirty or Old Filters


It’s easy to forget about air filters, but this is one of the most common reasons for HVAC airflow problems. Depending on your system, you will either need to clean or replace your filter. A dirty filter can restrict your home’s airflow and cause issues with your HVAC system.


During the summer, your A/C is constantly running. You should change your filter once a month. During the cooler season, you can change it every other month. Depending on your environment, such as furry pets or carpeting, you may need to change it more frequently.

Although cheap filters cost less up front, they may also need to be replaced more often.


Ductwork Issues


Ductwork delivers air to your rooms. Over time, ducts can develop small holes or cracks which allow the air to leak out. This can affect the amount of airflow they deliver to your rooms.


A professional can inspect your ductwork. In some cases, narrow ducts may be clogged and simply cleaning them can resolve the issue. In other cases, the ductwork may need to be replaced. This is not a DIY job.


Dirty Coils


Coils in your outdoor unit are exposed to the weather, debris, and who knows what else! Eventually, they can get dirty which may prevent the unit from functioning properly. This can lead to HVAC airflow issues.


If you’re wondering what you can do to help prevent dirty coils, you’re in luck. Simply keeping everything at least a few feet away from the unit can help prevent leaves and other debris from falling into your unit.


An air conditioning maintenance agreement includes an inspection and cleaning of the coils. Your technician will be able to monitor and help prevent issues before they turn into larger problems. A clean system runs more efficiently and can save you money.


Normal Wear and Tear


In a perfect world, you would never have HVAC airflow problems. Unfortunately, this is not a perfect world! Over time, normal wear and tear on your HVAC unit can cause airflow problems or even overheat your system. Be aware of the signs that your unit may be dying.


AC Blower Issues


The AC blower is located inside your unit and it may be the reason for your HVAC airflow problems. The blower is the “fan” that pushes the cool air through your ducts and into your home.


Sometimes, the blades begin to build up excessive amounts of dust or dirt, reducing your airflow. In this case, you should call a service technician to inspect and clean your unit. They’ll be able to diagnose the issue and get your unit working more efficiently in no time.


If cleaning the blades doesn’t help, you may need to replace your blower motor. In which case, you’ll want to hire a professional to come in and handle the job. While they’re in there, they can inspect the rest of your unit and discuss any other issues they see.


HVAC Airflow Problems: Know When to Call for Help


Now you know about a few of the most common HVAC airflow problems. Although you may be able to resolve some of the issues on your own, learning when to call someone qualified to help can save you time, money, and stress. If you’re having HVAC airflow problems...
