4 Causes of Poor Airflow

Cleaning Air Conditioner

When you turn on your air conditioner, you want cool air to flow out of your unit. If you get a low airflow, then you need to figure out what is causing the lack of air.
Your AC unit might be having airflow issues for a variety of reasons. For example, blocked and leaky ductwork, a clogged filter, blocked vents and registers, and an obstructed condenser unit are common causes of poor airflow. This guide discusses these issues and how you can fix them. Read on to learn more.

1. Blocked & Leaky Ductwork
Holes in your ductwork can cause many airflow problems. When you have holes and damage to your ductwork, air is going to leak out instead of flowing to its destination. This will result in less air coming out of your vents.
When less air is coming out of your vents, you are more likely to have hot and cold spots around your home. For example, one room may be freezing, and the room right next to it may be really hot because air is leaking out of your ducts.
In addition, when you have holes or leaks in your ductwork, your ducts will suck up dirt, dust, and contaminants through those holes. This will make your ductwork dirty and will decrease the quality of your air in your home.
Luckily, damaged ductwork can easily be repaired or replaced, resulting in better airflow throughout your home and better air quality as well.
2. Clogged Air Filter
While a dirty air filter can reduce the efficiency of your air conditioning unit, a clogged air filter can have negative consequences on your air conditioning system. When your air filter is clogged up, not enough air is able to pass through your filter.
A lack of air can cause your evaporator coils to freeze up because there isn’t warm air to cool off the coils as the refrigerant flows through them. This will cause your entire air conditioning unit to freeze up until you change the air filter and allow your unit time to defrost.
3. Blocked Vents & Registers
You should never close or block vents in your home. Blocked vents and registries in your home can actually harm your air conditioning system. Your air conditioning system is made to send air through all vents at once. When one of those vents are blocked, it can overload your air conditioner due to the misdirected air. That is not how your air conditioning system was made to work.
If you want to turn off the air conditioning in some of the rooms in your home, then it would be better to install a zone-controlled system instead of a central air conditioning system.
4. Dirty Condenser Cool
Over time, dust and debris can build up on the condenser coil. The condenser coil is vital to your air conditioning unit. The coil condenses the refrigerant and removes the heat from the air before it circulates through your home.
When the condenser coils become dirty, the dirt causes the coils to have to work harder to get the same job done. This extra work can wear down your air conditioning system and stress it out, which results in reduced airflow. Therefore, if you have reduced airflow, then you may be able to fix the issue by cleaning your condenser coils.
