What should I do if my AC is blowing warm air intermittently?

Intermittent warm air usually points to airflow, thermostat, or refrigerant issues. Start with quick checks, then schedule service if the problem returns.

Quick checks:

• Set thermostat to Cool, Auto, and 3–5°F below room.
• Replace a dirty filter.
• Clear debris around the outdoor unit (keep 2–3 ft clear).
• Reset a tripped breaker once. If it trips again, call us.
• If you see ice on lines or the indoor unit, turn AC Off and fan On for 4–6 hours.

We handle refrigerant leaks, drainage, electrical, thermostat faults, and frozen coils. Same‑day repairs are often possible, and most parts are on our trucks. Repairs come with a 2‑year warranty; 4 years for Priority Plan members.
