Hot Water Without the Five-Minute Wait

Read note
Hygrometer and thermostat on a Florida living-room wall with palmettos and storm light

Right-Size the AC, Then Wring Humidity

Cool is not dry. If the unit shuts off in under ten minutes, the coil never got to wring the air.

Leak sensor puck beside Florida washing-machine supply hoses

Five Places a Leak Puck Earns Rent

A five-pack is not a hobby. It is the rooms that ruin a Saturday if nobody is home to hear the hiss.

Read note
Leak sensor sitting in a wet Florida air-handler overflow pan

The Overflow Pan Should Text You

The float switch is a kill switch. The leak puck is a witness. You want both in a Florida closet.

Read note
Coastal Florida house under humid peak-week sky with no storm on the radar

Peak Week Relative Humidity When Season Is Quiet

Quiet season does not mean dry air. Peak week still pushes living-space relative humidity (RH) above 60%. Log it before you trust the thermostat.

Read note

Your Phone Knows Before the Ceiling

The future is not a gadget catalog. It is a text that the pan is wet while you are still at Publix.

Read note

Wet Florida lanai after overnight rain

Relative Humidity After Overnight Rain in Florida

The radar is clear. The drywall is not. Measure indoor relative humidity (RH) against a dry reference room before you buy another pint of capacity.

Pin moisture meter on wet Florida drywall

Drywall Can Look Dry and Still Be Wet

Paint hides water. After rain on a wall, pin 12 and 24 inches off the floor and compare to a dry closet. Sight is not a meter.

Read note
Closed Florida condo interior

The House Smelled Closed in August

The smell at the door is leftover humidity, not a dirty AC by default. Log relative humidity (RH) before you leave. Size for a house that sits empty.

Read note

The AC Was Cool. The Closet Was Dripping

The Bucket Overflowed at 2 a.m.

The overflow is the lesson. If the unit cannot drain itself, it is not a Florida condo setup. It is a bucket with a fan.

Read note
Small cube dehumidifier sitting undersized in a hot Florida two-car garage

A 35-Pint Cube in a Two-Car Garage

The Cube is honest about what it is: 35 pints for a small zone. A two-car Florida garage is not a small zone.

Florida living room humidity check

Why 68 Degrees Still Felt Clammy

Colder air is not drier air. If the house hits 68°F and still feels wet, you have a moisture problem, not a thermostat problem.

Read note

The Garage Is Its Own Climate

The first rusted wrench is the lesson. A Florida garage is not a room the house AC forgot. It is a second climate.
