Maintenance
how often should ac be serviced in florida
Twice a year in Florida — once before the cooling season and once in autumn — and it is defensible here for a climate reason rather than a sales one. Central Florida runs 3,450 to 3,700 annual cooling degree days against about 500 heating degree days, so a Winter Springs system logs the hours of a northern one at twice the rate.
Twice, and why
What each visit is for
NOAA’s 1991–2020 normals for the two nearest first-order stations put Central Florida at 3,452 to 3,694 annual cooling degree days against 468 to 525 heating degree days — about seven units of cooling for every one of heating.
The spring visit is the one that matters most: condensate drain and float switch cleared and tested before the humidity season blocks them; capacitor microfarads measured against the nameplate; refrigerant charge checked by superheat or subcooling; static pressure across the air handler recorded. The autumn visit is the strip-heat visit in this city — elements and sequencer on the 51.2% of homes built 1970–89 that were designed around them — and a coil clean after nine months of pollen and pool-cage debris.
Between visits, the filter is the homeowner’s job. In a 1980s Winter Springs house with a single central return, a blocked filter is not a nuisance; it is the thing that ices the coil. Why the AC freezes up.
What it should cost is on the maintenance plan page: less than the two diagnostics at a researched $70 to $200 each and the drain call at $80 to $250 that it replaces. And the visit no plan includes is Duke’s free Home Energy Check, which has to be within the 24 months before any rebate-eligible replacement. If the system is past fifteen, book it while nothing is broken. The order of operations.
