Florida's AC maintenance calendar looks nothing like a national guide. While most of the country has 4–6 months of cooling season, Central Florida runs AC for 9–10 months a year. That means more filter changes, more frequent tune-ups, and year-round attention to a system that almost never gets a real rest.
January — Post-Holiday Inspection
January is one of Florida's milder months — perfect for a quick system check before spring demand increases.
- ✅ Change air filter (first change of the year)
- ✅ Test thermostat accuracy
- ✅ Pour 1 cup diluted vinegar into condensate drain to prevent algae
- ✅ Inspect outdoor unit for debris from winter storms
- ✅ Check all vents are open and unobstructed
February — Pre-Spring Preparation
- ✅ Change air filter
- ✅ Schedule your spring professional tune-up now — March fills up fast
- ✅ Trim vegetation around outdoor unit — minimum 2 feet clearance on all sides
- ✅ Check window seals and weatherstripping for winter wear
March — Spring Tune-Up Month ⭐ Most Important
March is the most critical month in Florida's AC calendar. Schedule your professional tune-up before the heat hits and HVAC companies get slammed with emergency calls.
- ✅ Professional spring tune-up — coil cleaning, refrigerant check, electrical inspection
- ✅ Change air filter
- ✅ Clean outdoor condenser coils with garden hose
- ✅ Clear condensate drain line
- ✅ Test system in COOL mode — verify it's reaching setpoint efficiently
April — System Audit
- ✅ Change air filter (increase to every 30 days through October)
- ✅ Record your electric bill — this is your efficiency baseline before summer
- ✅ Set up smart thermostat programming for summer schedule
- ✅ Check all registers — make sure furniture hasn't shifted to block airflow
May — Pre-Summer Check
- ✅ Change air filter
- ✅ Pour vinegar in condensate drain — critical in humid months
- ✅ Clear any spring growth around outdoor unit
- ✅ Make sure attic vents are clear for maximum heat escape
June, July & August — Peak Demand Vigilance
Florida's peak demand period. Your system runs nearly continuously. This is when deferred maintenance causes failures — and emergency service in August means waiting days for a technician.
- ✅ Change air filter monthly without exception
- ✅ Inspect condensate drain pan weekly in August (peak algae growth)
- ✅ Verify system reaches setpoint within 20 minutes during peak afternoon heat
- ✅ Listen for any new noises — act immediately if you hear anything unusual
- ✅ Compare electric bill to April baseline — a significant increase indicates a problem
September — Hurricane Prep
- ✅ Change air filter
- ✅ Know how to shut off your AC at the disconnect box before a storm
- ✅ If a storm is approaching, shut down the system — power surges damage control boards
- ✅ After the storm, inspect outdoor unit for debris before restarting
- ✅ Wait 30 minutes after power restoration before restarting (allows refrigerant to stabilize)
October — Fall Tune-Up ⭐ Second Most Important
- ✅ Professional fall tune-up
- ✅ Change air filter
- ✅ Deep clean condensate drain system
- ✅ Check refrigerant levels after a full summer of operation
- ✅ Review summer electric bills — identify efficiency trends
November & December — Year-End
- ✅ Change air filter
- ✅ Test heating mode if you have a heat pump
- ✅ Document any issues from the past year for your spring tune-up
- ✅ Keep holiday decorations away from the outdoor unit — restricted airflow is a common December issue
