What to Do When Your AC Fails Suddenly
Step 1: Turn Off Your System
Shutting down a failing unit prevents catastrophic mechanical or electrical burnout.

Step 3: Keep Your Home Cool
Close all blinds/shades, limit interior doors, and avoid heat-generating appliances like ovens or dryers.
Step 4: Document Symptoms
Note any unusual grinding sounds, burning smells, or water leaks to help our technician diagnose the issue faster upon arrival.
