Azalea Festival weekend, yellow dust on every truck in town, and what to install before next March

A Hammock household, the second week of March

Picture a family in the Palatka South Historic District, in a 1920s house with a 1990s duct retrofit, spending Florida Azalea Festival weekend sneezing. The porch is yellow, the car is yellow, and inside the house the air is not much better: the one-inch filter at the return went grey in two weeks, the window sills collect a fine grit that has as much to do with the Georgia-Pacific Palatka mill and the potato fields across the river around East Palatka as with the trees, and in the evenings the house smells faintly like a damp towel.

By the second week of March they call. What they want is a house that feels different from the yard. That is an equipment question, and the equipment comes in three kinds.

What we recommend, piece by piece

Filtration. The first and most cost-effective step. A media filter cabinet with a four- or five-inch pleated filter replaces the one-inch slot and catches far more of the pollen, mill dust and agricultural grit without starving the blower. For a household with asthma or allergies, a whole-house electronic air cleaner steps up from there.

Dehumidification. Palatka’s river-basin summer and the shoulder months in May and October leave a lot of houses damp even when the thermostat is satisfied. A whole-house dehumidifier plumbed into the return side holds indoor humidity near 50 percent, which is the single biggest change in how a house smells.

Purification. A UV lamp at the evaporator coil prevents the biological film that builds on a wet coil in this climate. A carbon stage handles odors, including the smoke that drifts in from pine-plantation burns in a dry spring.

Not every house needs all three. A sealed newer house on the outskirts may only need better filtration. A lake cottage near Interlachen on a crawlspace probably needs the dehumidifier most. The recommendation follows the house.

What the install looks like at the handler

Most indoor air equipment attaches to the existing air handler, so the work happens at the closet, garage or utility room where the handler lives. The media cabinet goes on the return side, which often means rebuilding the return connection and sealing it so air cannot bypass the filter. The UV lamp mounts inside the handler above the coil with its own power. A whole-house dehumidifier is the largest piece: it ducts into the return, needs a drain and a circuit, and takes most of a day on its own. Well-water houses get the dehumidifier drain routed and trapped with the same care as the condensate line, because mineral scale builds in both.

Ask about a spring air quality package

The house the following spring

The change shows up in small ways. The filter gets changed a few times a year instead of monthly. The sills stay cleaner. The house holds 50 percent humidity in August and the towel smell is gone. And next March, when the pollen comes down on Ravine Gardens and the festival crowds, the inside of the house is somewhere to go.
