The AC at this Fort Smith home froze up a few weeks earlier, so it was turned off. Someone had forced the wrong size air filter into the unit. After that was sorted out, the system ran fine for about a week and then stopped working right again.
What Our Technician Found
Our technician found a filter packed solid with dust, which chokes off the air the system needs. A clogged filter is a common cause of a frozen coil. He also found the condensate drain line (the pipe that carries water away from the indoor unit) clogged and cleared it.

What We Completed
- Checked why the system froze up and quit.
- Checked the refrigerant with gauges.
- Cleared the clogged condensate drain line.
- Went over what we found with the homeowner.
The Result
The drain line is clear. Keeping the right size filter in place, and changing it often, helps keep the coil from freezing again. Learn more about our AC repair.
What Homeowners Can Learn From This Job
- Use the right size filter. A filter that does not fit lets dirt by or blocks air.
- Change it often. A packed filter can freeze the coil.
- A frozen AC should be turned off. Then call for service.
