Why does water leak from my air handler?

A clogged condensate drain is the usual cause: the system pulls gallons of moisture from humid air daily, and algae blockages back water up into the pan and beyond. Shut the system off and have a pro clear the line.

Why is my outdoor unit rusting?

Salt air corrodes condenser coils, cabinets, and fasteners far faster than inland — it is the norm near the coast, not a defect. A pro can assess whether coil cleaning and corrosion treatment buy time, or whether the unit's efficiency has already fallen too far.

How often should AC be serviced in Jacksonville?

At least once a year before the brutal season — and with near year-round runtime, many Jacksonville pros recommend twice-yearly checks. Constant operation wears electrical components and coils fast, and salt air accelerates the decline.

Jacksonville runs on air conditioning the way northern cities run on heat: the system works nearly every day of the year, and the long, brutal cooling season decides how long equipment survives.

Winter barely registers — but the rare cold snap still finds heat pumps on backup heat and furnaces that have sat idle all year failing to fire. Near the water, salt air and storm exposure shorten outdoor equipment life — post-storm inspection of the condenser is routine care here.

When heating or cooling trouble hits your Jacksonville home — a musty smell every time the system kicks on — AirFlow HVAC connects you with an independent local HVAC pro. Tell us what is happening and we will match you with a pro nearby, fast.

Homes here, and the HVAC problems they get

Local housing notes

1970s–2000s tract builds where builder-grade ACs are failing in waves.
Newer energy-code builds — tighter, but still dependent on humidity control.
Concrete-block homes that trap humidity and challenge even well-sized systems.

Common local HVAC issues

Condensate overflows: constant dehumidification plus algae means drain lines clog often — and overflow fast.
Oversized short-cycling systems: cool but clammy is the classic Florida complaint.
High indoor humidity: poor airflow or wrong sizing leaves homes sticky even with a running AC.
Salt-air corrosion: coils, cabinets, and fasteners corrode years ahead of inland schedules.
Homes near the beaches and the Intracoastal breathe salt air year-round, and coil fins pit and flake years before inland systems show the same wear.
Older homes in Riverside and San Marco hide cast-iron era plumbing chases that double as accidental duct routes, leaking conditioned air into wall cavities.
Tropical storms stall over the First Coast and dump double-digit inches, flooding crawlspaces and leaving air handlers underneath raised homes sitting in water.

Jacksonville FAQs

Usually an oversized system that short-cycles — it cools the air before running long enough to dehumidify — or restricted airflow. A pro can check sizing and airflow, and discuss dehumidification options.
