The Typical Reasons for Poor HVAC Airflow



HVAC Repair ServiceThe HVAC system is supposed to keep temperature and humidity at proper levels at home. For it to do its job well, though, proper maintenance is crucial. And yet sometimes, problems arise no matter how thorough and regular your maintenance is. One common problem of HVAC systems is poor airflow.

Common HVAC Airflow Problems

Any of these signs are considered to be airflow problems, which could be caused by one or more factors:

  • too cold or too warm air coming out
  • too little air coming out
  • no air coming out
  • hot spots in certain areas

Top Reasons for Airflow Problems

  • Dirty Filters

Your unit’s filters could be blocked with dirt buildup. An HVAC filter must be replaced at least every three months, according to House Logic. Some HVAC has their filters installed in more than just one spot, so check your unit and replace if necessary.

  • Dead Thermostat Batteries

It could happen that you called for HVAC service only to feel silly in the end that your thermostat batteries are the only problem. A blank screen would best indicate the need for new batteries.

  • Blocked Condenser Unit

Go outside and check the condenser unit. The air registry could be obstructed by leaves or other debris, which limit airflow. An obstructed condenser does not just cause airflow problems, but could also make the unit overheat.

  • Ductwork Problems

Hire a professional Montgomery HVAC technician to inspect the duct-work. Chances are if it’s not dirty and blocked, then there could be leaks. Regular inspection is important to diagnose these problems immediately.

  • Dirty Coils

The coils should also be clean. Dirt buildup causes the coils to work harder, reducing their heat-absorbing capacity.

  • Refrigerant Problems

Refrigerant problems do not only cause poor airflow, but also reduced cooling. Check for leaks to avoid a huge decline in unit performance.

There are other reasons for poor HVAC airflow. It’s important to identify the main cause immediately to prevent further damage to the unit. Call an HVAC technician for a thorough inspection.
