Over time, HVAC airflow problems can develop in your air conditioner due to the lack of periodic maintenance and timely tune-ups. With proper maintenance of your air conditioning unit, you can enjoy superior and uninterrupted AC performance throughout the summer season. Read further about common HVAC airflow problems and solutions.
Symptoms of Weak HVAC Airflow problems can be identified through the following symptoms:
- Air conditioner blowing warm air
- Your space having hot and cold spots
- Low airflow or no air coming out from vents
- Pressure imbalance causing doors to slam by themselves and strange whistling sounds.
Causes of HVAC Airflow Problems
Here are some significant reasons why your air conditioner is causing airflow problems and which airflow troubleshooting steps to consider:
1. Dirty Coils
Coils will retain the heat if they become dirty or clogged with the outside dust and debris. Your air conditioner has to perform overtime to cool your space if it has dirty coils. This can eventually result in airflow problems. Get your coils cleaned annually to prevent airflow problems.
2. Clogged Filters
An air filter clogged with dust and debris will block the airflow causing hot and cold spots throughout your space. You can change the air filter once a month or consider manufacturer’s instructions and your usage to determine the interval you need to change the filter.
3. Faulty Thermostat
You must check your thermostat settings if you have airflow problems. If your thermostat is set to “ON” instead of “Auto,” your air conditioner will run throughout, regardless of whether or not it is cooling the air. Keep your thermostat settings to “Auto” to make sure your fan will run only when your AC is cooling the air.
4. Oversized AC Unit
If the capacity of your AC is too large for the space that needs cooling, it won’t cool the space efficiently. Oversizing may be the problem if you notice that your ac is turning on and off frequently. You can solve this problem through an experienced HVAC design expert.
5. Refrigerant Leaks
When the refrigerant in your AC unit starts leaking, you will experience reduced cooling or airflow problems. Refrigerant leaks can also slow down your unit’s performance. Hire professionals to inspect your air conditioner for leaks and repair them sooner.

FAQ’s on HVAC Airflow Issues
Why Is Air Not Coming Out of My Vents?
The fan is responsible for blowing the air in and out of your vents. If the fan is overloaded with dirt, airflow will be blocked. Also, a broken motor, a loose fan belt or a stuck wheel can reduce the amount of airflow coming from your vents.
How Do I Increase the Airflow in My HVAC System?
You can increase the airflow in your HVAC system by following these tips:
- Change your air filters regularly and clean your air return grill with a vacuum cleaner if it looks dusty
- Clean the vents in your home
- Seal your leaky air ducts
