5 Airflow Problems That Need HVAC Repair

by Clara Fernandez

Do you feel hot or cold in your house when you expect otherwise? It is a sign that your AC has airflow problems. You will also hear whistling sounds when the AC is on. Another sure sign would be the lack of air flowing from the AC. Airflow problems make the house uncomfortable and sometimes outright uninhabitable. You need to engage skilled HVAC repair services to inspect, diagnose and fix whatever problem is causing poor airflow. What are some of these problems that cause poor airflow?

1. Faulty Furnace

The heater is a common cause of poor airflow. If the heater is faulty, the house will feel cold even with the thermostat at high settings. A furnace is a complex unit with various components that can develop electrical and mechanical faults. A furnace repair technician can test components like the blower, ignition unit, and thermocouple for faults. 

2. Blocked Vents   

Blocked vents are another cause of poor airflow. This blockage can be caused by furniture that has been pushed too close to a vent. You will notice poor or no air drafts in the room. You can easily unblock vents by removing these obstacles.  

3. Faulty Thermostat   

A faulty thermostat will not allow your AC to work at its optimal levels. You will feel the temperature is too hot even when the thermostat is set to the right temperature. The thermostat can fall out of calibration as it gets older. A HVAC repair technician can test the thermostat to check if the electrical system is working properly. You can also upgrade the thermostat to a smart unit for better AC efficiency. 

4. Clogged Filters   

Clogs in filters are another cause of poor airflow. They impede airflow and make the AC work harder to push air through the ducts. They can also cause health problems as the air contains bacteria, viruses, pet dander, dust, and pollen. You should replace filters at least once every change of the season. 

5. Wrong-sized HVAC    

The wrong-sized HVAC system will be inefficient. You will also see the AC turning on and off more frequently than necessary, leading to raised power bills. This is because the temperature rises or cools too fast, making the unit try to regularize it again. 

Installing an appropriate HVAC system starts at the design stage. You should involve a professional HVAC service to assess, calculate, and design the HVAC. Replacing the HVAC is costly, the reason you need to do it right from the start. 

Is your AC not meeting your expectations? Call a HVAC repair service to diagnose and fix any faults, and restore expected comfort in your home.
