What is actually going on
The unit runs and cools slightly, but very little air comes out of the vents.
The realistic causes, in order
Blocked filters, the first and cheapest thing to eliminate A dirty blower wheel, which loses a surprising amount of performance when coated A partially iced indoor coil, which points at charge or airflow problems upstream
What we test on site
Filter and blower wheel condition Coil temperature and any icing Fan speed settings and whether louvre positions are restricting output
Get poor airflow from an air conditioning unit diagnosed properly
A deep clean restores most units; where icing is involved the refrigeration side needs checking too.
Questions we get asked
Why is poor airflow from an air conditioning unit happening on an air conditioning system?

What normally puts poor airflow from an air conditioning unit right?
A deep clean restores most units; where icing is involved the refrigeration side needs checking too.
Is it safe to keep using the system with poor airflow from an air conditioning unit?
Running a system with an iced coil can damage the compressor. If you see ice, switch it off and let it defrost rather than pushing on.
