In a Central Florida summer, a no-cool call is an emergency. Before you pick up the phone, walk this 60-second list — about 1 in 3 of these calls turns out to be something a homeowner can resolve in two minutes.
1. Thermostat first
Set it to COOL (not AUTO from heat mode), setpoint below room temp, fan on AUTO. Blank screen = replace batteries.
2. Filter check
A clogged filter freezes the indoor coil and stops airflow. Pull the filter — if you can't see light through it, replace it and let the system thaw 2–3 hours before restarting.
3. Breaker & disconnect
Check the breaker for the air handler AND the outdoor unit. The outdoor disconnect (gray box near the condenser) can also trip.
4. Outdoor unit
Is it running? Ice on the lines = call. No fan spinning = call. Buzzing or humming with no fan = capacitor (call).
Quick answers, straight up.
How long can I run my AC with a dirty filter?
+
Don't. A clogged filter restricts airflow, freezes the coil, and can burn out the blower motor — a $400–$900 repair vs. a $15 filter.
Should I add refrigerant myself?
+
No. Adding refrigerant to a leaking system is illegal without EPA 608 certification and won't fix the leak. We find it, repair it, recharge to spec.
