Common Airflow Issues With HVAC Systems

Insights From Your Home Comfort Specialists

HVAC airflow from vents

Imagine waking up on a chilly winter morning or a hot summer day, only to find something is not right with your heating or air conditioning! Your mind is already dreading what may be wrong with your HVAC system, how long will it take to fix the issue, or how big a hole it will burn in your pocket to get it repaired. However, before you panic or think of the worst, check for these signs which may throw some light on the problem:

  • Are you sensing distinct hot and cold spots throughout your home?
  • Do you hear any strange whistling sounds or find that some areas are very drafty?
  • When you check your vents, is there is no air coming from them even when the unit is “ON”?

If you are experiencing some of these signs, it may be nothing but an airflow problem. While there are several reasons for a restricted flow, the good news is that it is relatively easy and inexpensive to fix it. The specialists at Bi-County Inc. can explain how you may be able to fix or prevent the following issues…

Key Reasons For HVAC Airflow Issues:

  1. Condenser Unit Obstructions or Dirty Coils: One of the most common airflow problems is that the outside condenser unit can get obstructed by leaves, dirt or debris. The coils may become so dirty that they cannot release the necessary amount of heat, which in turn overtaxes the HVAC system. So simply clear the area around the unit and you should see a marked improvement in the airflow inside. Routine inspection and maintenance services at regular intervals by Bi-County can help prevent this.
  2. Blocked Vents or Clogged Filters: Often when people do not agree on a common thermostat setting, they block the vent with furniture, planters, or other items. Just move around the pieces to ensure that your vents and registers are not obstructed. If blocked vents are not the issue, the problem could be with your HVAC filter. Clean or replace the filter and clean any dust or debris that may be hindering the airflow.
  3. Leaky Ductwork: If dust and debris gets past your filters it can clog the ducts, impacting the operating capacity of your HVAC system. If your home is older construction, the walls around the ductwork could develop cracks or holes that cause leakages in the airflow. Also in older buildings, there is the risk of rodents or birds making nests inside the ductwork. To avoid these issues, it is best to get your ducts inspected and cleaned periodically.
  4. Sluggish Fan Motor: Within your HVAC system, it is the blower fans that move the air through the ducts and into your space for heating or cooling. If the fan or its motor is not functioning at optimum capacity, it can impact the airflow significantly. Clean and lubricate the fan to help speed it up or call in one of our experienced repair technicians to get the motor replaced.
  5. Low Refrigerant Levels: Refrigerant levels tend to drop over time due to continuous usage, and also in case of a leak in the system. Bi-County’s trained service professionals will check for leaks and top-up the refrigerant levels during any routine maintenance service.

Although the reasons for an impacted airflow may be quite varied, the easiest way to prevent these issues is to sign up for preventive maintenance service.
