Are your AC systems blowing warm air or little to no air? Do you have cold or hot spots in your room? Does your room have drafty areas or doors that slam by themselves? If so, then you may be experiencing an HVAC airflow problem, which may cause compressor failure. But such HVAC airflow problems shouldn’t worry you because they’re easy and cheap to fix for your commercial HVAC contractor.

Read on to get a glimpse of the top eight problems that impede HVAC airflow and how to correct them.

1. Oversized AC Unit

Big HVAC machines may deliver better temperature control, but big is not always better in HVAC sizing. HVAC units with a big capacity may run poorly because they’ll often cycle on and off when they’ve lowered the temperature of your limited space. As such, they won’t run long enough to remove humidity, and your house may feel stuffy. You should thus consult a commercial HVAC contractor before installing an HVAC unit to get the right size for your space.

2. Obstruction of the Condenser Unit

The condensing unit of most HVAC systems is located in a mechanical room or on the outer part of your wall. These condensing units can be obstructed by debris, leaves, or any objects positioned on their way. Such obstruction causes overheating because of the limited airflow to your HVAC unit. To correct this problem, you should get your commercial contractor to clear the area around your condensing unit.

3. Leaking or Low Refrigerant

If the refrigerant in an HVAC system leaks out, then your HVAC system may experience airflow problems and diminished cooling. You should get a commercial HVAC contractor to test the leak and repair your HVAC system.

4. Dirty Condenser Coils

Condenser coils dissipate heat that’s removed from your rooms, and when such coils get dirty, their capacity to transfer heat declines. Such dirt compels your HVAC system to work harder than usual. You need to clean the coils to improve their efficiency to remove heat.

5. Clogged HVAC Filters

HVAC system filters remove debris and dust from the air and prevent it from getting into your ducts and equipment. Overloaded filters block the flow of air through your unit, and thus causing cold or hot spots. You should change your HVAC system filters, as advised by your HVAC manufacturer.

6. Sluggish Fan Motors

Blower fans in HVAC systems aid in moving air through the ducts of the system and the room. When such blower fans get slow, then the airflow is impeded, and the HVAC system fails to work well. You should get commercial contractors to clean the fan or replace it to improve fan speed and airflow.

7. Blocked or Leaking Ducts

All the dust that passes through the filters get stuck in the ductwork, and it can lead to clogging. Sometimes insects, birds, and rodents also build nests that can block HVAC ducts. The ducts may also develop leaking cracks or holes. The leaks or clogging reduces the effectiveness of your HVAC system. You should get commercial HVAC cleaning services to keep your ducts clean.

8. Outdated HVAC Design

If you have rearranged your room or renovated it without updating your HVAC system or its ductwork, then your HVAC system may lose its capacity to work well in the new space. You should consult a commercial HVAC contractor when renovating your rooms to get HVAC design services in tailoring new HVAC systems that meet the new space requirements.

The revenue generated by the HVAC industry has risen by approximately 3% in the past five years. So have the HVAC problems, more so the airflow problems, which need to be eliminated for the industry to be more efficient.

Poor HVAC airflow reduces the effectiveness of the system to work within your rooms. But the worst problem is that if such a problem doesn’t get corrected in due time, then your entire HVAC system may fail. As such, you should always get your commercial HVAC contractor to monitor your HVAC system efficiency and inspect it to find the possible causes of airflow problems.
