Although air conditioning is a boon to your household, it can break down in times of need and leave you at the mercy of summer's unbearably hot temperatures. The best way to prevent unexpected AC downtime is to watch out for early indications of trouble and take corrective action before it is too late.

If you are having weak airflow with your residential air conditioner, these are the potential sources of the problem.

Dirty Filter 

The air inside your home contains countless microscopic dirt particles that make your house dusty and contribute to household allergies. Inhalation of these airborne particles can also worsen the condition of people with respiratory illnesses such as asthma. 

Your air conditioning unit contains a filter that removes these particles from the unconditioned air pulled into it, ensuring the cooled air returned to your home is clean and healthy to breathe. As the filter accumulates dirt, it becomes clogged over time and restricts the free flow of air through it. When this happens, you will experience weak airflow with your AC system.

To fix the problem, you will need to clean or replace the dirty air filter, depending on the type of filter you have.

Blocked Ductwork

Does your air conditioner rely on ductwork to keep your house cool in hot weather? The dirt that infiltrates and builds up inside the air ducts over time can form blockages that prevent air from moving freely through the pipes. Consequently, you will not receive sufficient airflow at the air supply registers.

If you are experiencing weak AC airflow due to blocked ductwork, you need to schedule a professional air duct cleaning. 

Leaky Ductwork

Leaks are another ductwork-related issue that may result in poor AC airflow. If your HVAC ductwork is leaky, some of the cooled air will be lost before it reaches the air supply registers.

To solve the problem, you will need to have the ductwork checked for leaks and repaired to make them airtight again.  

Obstructed Air Registers

All the air registers in your home must remain unobstructed to facilitate smooth movement of air into and out of your air conditioning system. If something impedes the air movement into and out of these registers, you will experience poor airflow in your space-cooling system. 

You can fix the problem by removing anything that blocks the path of air moving into or out of your AC system.

Weak or poor airflow is an AC problem that can occur due to multiple factors. Contact an AC repair service to learn more.
