The house is at 72 and it still feels awful. That is humidity, not temperature, and no amount of extra cooling fixes it.
This page covers how to tell humidity is your problem, why Houston homes get it worse than most, the difference between a portable unit and a whole home system, and what changes once it is under control.
Your air conditioner removes some moisture as a side effect of cooling. That is all it is designed to do: a side effect. When outdoor humidity sits where ours does for months at a time, that side effect is not enough, and the house ends up cool and clammy at the same time.
That last one is worth sitting with. Overcooling to chase a humidity problem is expensive, it makes the house cold rather than comfortable, and it does not actually solve anything.
Indoor humidity should sit between 40 and 50 percent. Houston spends much of the year well above that outdoors, and every time a door opens, that air comes in with it.
There is a second problem specific to efficient homes. A well sealed, well insulated house holds moisture in as effectively as it holds heat out. Newer construction and recently upgraded homes often have worse humidity than the drafty houses they replaced.
Oversized equipment makes it worse. An oversized air conditioner cools the house fast, shuts off, and never runs long enough to pull real moisture out. Bigger is not better here, and it is one reason a replacement quote should follow a load calculation rather than a guess.
Handles one room, needs emptying, and runs loudly in the space you are trying to enjoy. For a closet or a small problem area, that can be enough.
Ties into your existing ductwork and treats every room the system reaches. Drains on its own, runs quietly because it is not in your living space, and works with your AC rather than against it.
A whole home unit maintains a humidity level you set, the way a thermostat maintains temperature. You stop thinking about it.
Humidity control is one part of indoor air quality. Filtration handles particles, ventilation handles stale air, and dehumidification handles moisture. They solve different problems, and it is worth knowing which one you actually have.
The unit uses power, but most households come out even or ahead, because the air conditioner runs less and the thermostat sits higher.
Into your existing condensate drain. There is nothing to empty.
In most cases yes. It ties into the ductwork, so what matters is whether there is room to make the connection properly.
Between 45 and 50 percent suits most Houston homes. Lower is not better, it just costs more to run.
No, different job. The dehumidifier handles moisture, the filter handles particles.
We measure the humidity in the house before recommending anything. Sometimes the answer is a dehumidifier. Sometimes it is that the existing equipment is oversized and short cycling.
