Answers to Common Questions
View All FAQsWhy Is My AC Running But Not Blowing Cold Air?
Your AC usually runs but doesn’t cool because of low refrigerant, a clogged filter, dirty/frozen coils, a thermostat setting issue, or an electrical fault. Milestone performs in‑depth diagnostics, checks refrigerant levels and charges if low, cleans coils, replaces filters, and repairs thermostats or wiring. We offer same‑day and 24/7 emergency service across DFW, including Little Elm and Frisco.
Quick checks:
- Set thermostat to Cool and 5°F below room temp.
- Replace a dirty filter.
- Clear debris from the outdoor unit.
- If you see ice on lines, turn AC off to thaw.
- Check the breaker.
