The quality of your HVAC system’s airflow directly affects the unit’s efficiency. If you notice that your airflow isn’t as strong as it used to be, this may be an indication that your unit needs serviced by a licensed AC repairman or that your ductwork doesn’t match your HVAC system.
How does airflow affect your HVAC system’s efficiency, and why is it important not to ignore weak airflow? Find out in this post by your professional HVAC specialists.
When you’re shopping for a new HVAC system, you probably consider the SEER rating. You might also think about where your new HVAC system should be located and what kind of thermostat to use with it. The factor that tends to be overlooked the most, however, is quality of airflow. You may have a good-quality HVAC system, but if the ductwork and registers are restricting airflow, you won’t be able to enjoy its full benefits.
Signs of Airflow Problems
You might not be able to tell immediately if you have airflow problems with your HVAC unit unless you hire an HVAC contractor to take a closer look. However, before you do that, these signs should give you an idea that there’s an airflow issue:
- Uneven heating or cooling – Airflow problems often lead to inconsistencies in the amount of air blown into different areas of your home. If one or two rooms in your house are hotter or colder than the rest of the house, there might be airflow issues.
- Weak airflow from registers – The flow of air into every part of your home should be the same, so if there are registers that seem to blow less air than others, this is a problem.
- Uneven pressure – Your HVAC unit shouldn’t make whistling sounds or create drafty areas, and it shouldn’t be able to close a door when blowing air into a room. If it does, this often means there is a pressure imbalance.
The Cost of Airflow Problems
If your HVAC unit has reduced airflow, these are the potential problems you may have to face:
- Wasted energy – It’s costly to operate an HVAC system with reduced airflow because it has to work harder to provide enough heating or cooling to make your home comfortable. You also have to pay more for the energy it consumes.
- HVAC failure – Working too hard might lead to your HVAC unit failing long before it reaches the end of its lifespan. This will force you to replace it, which isn’t exactly cheap.
- Your comfort could be affected – It takes much more time for your HVAC system to make your home comfortable enough if its airflow is weak. Sometimes, it won’t even succeed in doing this.
