3 Causes of Low Air Flow in Your Air Conditioner

Monday, May 12th, 2014 at 11:36 am

In order to properly cool a home during the heat of summer, an air conditioning system must achieve two goals: an effective reduction in the temperature of the air, and an effective flow of air through the ventilation system. One without the other means reduced comfort. An air conditioner may have no trouble removing heat from the air inside the evaporator unit, but unless it can adequately distribute this conditioned air, the house will suffer from uneven cooling.

If you notice warm spots in your home when the air conditioner is running, check on the vents to see if the airflow is at its expected level. If it feels weak, then you probably have repair needs for the AC. Call Next Generation Air & Heat Inc. for fast and reliable air conditioning repair in Merritt Island, FL.

What causes low airflow? There are a number of possibilities, but here are three of the most common:

1. Clogged air filter

Debris that enters the return air vents of an HVAC system can potentially damage the interior components of an air conditioner. The air filter traps debris to protect the system. But over time, the filter will accumulate so many trapped particles that it will become clogged. This will throttle the airflow into the system, and consequently lower the air coming out of the system. Make sure you change the filter once a month while you have the air conditioner running regularly. If an air filter becomes excessively clogged, you may need to have a repair technician look for additional problems it may have caused.

2. Blower fan troubles

The power behind the airflow coming out of your air conditioner is the blower fan that draws air from the return vents and then sends it through the evaporator coils for cooling and on into the ductwork to the vents that open on your rooms. The blower can malfunction for various reasons: broken belt, burnt-out motor, dead capacitors, failed electric relays. Technicians will investigate to find out what has caused the blower to drop in power and efficiency.

3. Ductwork leaks

This problem doesn’t come from the AC itself, but from the ducts connected to it. The ventilation shafts must maintain an airtight seal from the air handler all the way to the vents, or else air pressure will drop as air escapes through the leaks. Breaks along the ducts from corrosion, construction damage, or poor installation will siphon away the air that should blow out the vents. Duct specialists can handle sealing and repairing the vents.
