When only a little air comes from your vents, your home will not cool well. Here is what may be causing it.
A dirty filter
A clogged filter is the number one cause of weak airflow. Check yours first and put in a clean one if it is dusty.
Blocked or leaky ducts
If your ducts are blocked or have leaks, air escapes before it reaches your rooms. This wastes power and leaves you hot.
A failing blower
The blower is the fan that pushes air through your home. If it is going bad, airflow drops. This needs a tech. Call PolarFix and we will fix it.
