Florida AC systems run nearly year-round, which means maintenance tasks that other homeowners do once a year need to happen more frequently here. This checklist covers everything you need to do monthly, seasonally, and annually to keep your system running efficiently and avoid costly breakdowns.
Monthly Tasks (Year-Round)
- ✅ Change the air filter — Florida systems need filter changes every 30–45 days, not 90. A clogged filter is the #1 cause of AC problems.
- ✅ Pour diluted vinegar in the condensate drain — Florida's humidity creates constant algae growth in drain lines. One cup monthly prevents clogs.
- ✅ Check the condensate drain pan — Look for standing water under the air handler. Any pooling water means the drain is backing up.
- ✅ Clear the outdoor unit — Remove leaves, grass clippings, and debris. Keep 2 feet of clearance around all sides.
- ✅ Check thermostat accuracy — Place a thermometer near the thermostat. If the reading differs by more than 2°F, the thermostat may need calibration.
Spring Checklist (March–April) ⭐ Most Critical
- ✅ Schedule professional spring tune-up — Do this in March before HVAC companies get slammed with summer emergency calls.
- ✅ Test cooling mode — Run system in cooling for 30 minutes and verify it reaches setpoint.
- ✅ Inspect refrigerant lines — Look for ice buildup or oily residue (sign of refrigerant leak) on the lines running to the outdoor unit.
- ✅ Clean condenser coils — Gently rinse outdoor unit fins with garden hose spraying from inside out.
- ✅ Trim vegetation — Cut back any plants that have grown within 2 feet of the outdoor unit over winter.
- ✅ Check and set summer thermostat schedule — 78°F when home, 82°F when away.
- ✅ Inspect ductwork for disconnections — Check accessible ducts in attic or crawlspace for gaps.
Summer Checklist (May–September)
- ✅ Increase filter change frequency — Every 30 days during peak summer months without exception.
- ✅ Monitor electric bill — A sudden 25%+ increase signals an efficiency problem that needs diagnosis.
- ✅ Check condensate drain weekly in August — Peak algae growth month in Florida.
- ✅ Verify system reaches setpoint — On a 95°F day the system should reach your setpoint within 20–30 minutes.
- ✅ Hurricane prep (September) — Know how to shut off the AC at the disconnect before a storm. Shut down during storms to protect the control board from power surges.
Fall Checklist (October–November) ⭐ Second Most Critical
- ✅ Schedule professional fall tune-up — After a full summer of hard running, systems need a check-up.
- ✅ Deep clean condensate drain system — End of summer often leaves significant buildup.
- ✅ Verify refrigerant levels — Small leaks become apparent after a full summer season.
- ✅ Check capacitors — Capacitors that barely survived summer should be replaced proactively before next year.
- ✅ Test heating mode — Florida winters are mild but you want to know the heat works before you need it.
Annual Professional Service Checklist
A professional tune-up should include all of the following. If a technician quotes a "tune-up" but doesn't mention these items, ask specifically:
- ✅ Refrigerant level check and adjustment
- ✅ Evaporator and condenser coil cleaning
- ✅ Electrical connection inspection and tightening
- ✅ Capacitor and contactor testing
- ✅ Blower motor and fan inspection
- ✅ Condensate drain clearing and treatment
- ✅ Thermostat calibration check
- ✅ Duct connection visual inspection
- ✅ System airflow measurement
- ✅ Written condition report
