HVAC in Mississippi has to pull water out of river air, not only drop the temperature on a July afternoon. A coil that short cycles, a closet that smells sweet, or a bedroom that stays clammy is the report that matters. If the house cools and the towels still never dry, say that. The equipment is losing to humidity.
Attic air handlers sit in heat that bakes the ducts before the air reaches a back bedroom. Crawl ducts on pier houses sweat, sag, and come off the collar, so the crawl is cool and the room is not. Window units in Delta cottages fight the same wet air one room at a time and leave the hall uncontrolled. A system that blasts cold and shuts off does not dry the sofa, the shoes, or the closet.
Coils slime over in this climate. Airflow falls, the line ices on a humid night, and a ceiling stain under the handler looks like a roof leak. Filters pack with pine pollen and with the dust a gravel road brings. Heat in a Tupelo or Starkville attic is a different complaint from salt film and a rusted disconnect nearer the coast. A sunk pad in gumbo twists the cabinet until the fan rubs.
Walk outside before you call. Does the fan run. Is the line iced. Is water pouring from the drain or from the pan into the attic. Inside, name the rooms that fail and whether the problem is smell, noise, heat, or wet air. A silent outdoor unit and a running indoor fan is one failure. Both silent is another. A flooded switch under a pier house is a third.
Have the house type ready. Pier cottage with window units, slab ranch with an attic handler, two-story with the upstairs on a long duct. Say what changed, such as a closed bedroom door, a new filter nobody can find, or a storm that wet the equipment. Do not start with a brand you half remember. Start with the room that will not dry and the water you can see. Call the number on this page.
