Yes—turn the AC’s cooling off if it’s blowing warm air, then run the fan only while you check a few simple things. The most common cause is a wrong thermostat setting or blocked airflow, which can make the system overheat or ice up and blow warm.
Our team services homes across the Las Vegas Valley, including areas near Whitney, and we see this often when filters are clogged or the outdoor unit isn’t running. If the indoor blower runs but the outdoor unit is silent, a tripped breaker or safety switch is a likely culprit.
Try these quick checks before calling:
- Set thermostat to Cool and Fan Auto; confirm target temperature is below room temp.
- Replace a dirty air filter to restore airflow.
- Check the breaker and outdoor disconnect; reset once if tripped.
- Look for ice on lines or coil; if present, keep Fan On for 30–60 minutes to thaw.
If the air stays warm after these checks, book a professional diagnostic to prevent compressor damage.
