Dew Point and Latent Load Here
Gulf moisture keeps our dew points high from April into October. That moisture is latent load: heat stored in water vapor, not in air temperature. Cooling equipment answers the thermostat, and a thermostat reads temperature only. The temperature target gets met while moisture stays put.
- High Gulf dew points from April into October
- Latent load is moisture, not temperature
- A thermostat cannot see relative humidity
Cool but Clammy, and Why It Matters
The result is a home that hits 74 degrees and still feels damp. The U.S. Environmental Protection Agency recommends keeping indoor relative humidity below 60 percent, and ideally between 30 and 50 percent. Above 60 percent, damp indoor air supports mold growth and dust mites.
- EPA guidance: below 60 percent, ideally 30 to 50
- Damp air above 60 percent supports mold and mites
- Damp air feels warmer than the thermostat reads
How We Measure It and Fix It
We start with a reading, not a guess. Our NATE certified technicians log relative humidity in the living space, set a target inside the EPA range, then size dedicated dehumidification to hold it. Pricing is upfront, financing is available, and the work carries our satisfaction guarantee.

Signs Your Home Has a Humidity Problem
Clammy Air at 74 Degrees
The thermostat reads cool, but the air still feels heavy and damp on your skin.
Sweating Windows and Vents
Condensation on glass, supply registers, or toilet tanks points to high humidity.
Musty Smell Indoors
A damp odor in closets, hallways, or near a return says moisture is sitting inside.
Mold Spots and Stained Grout
Dark spots on bath grout, window sills, or closet walls follow high humidity.
Short Cooling Cycles
The system satisfies the thermostat fast, then stops before it wrings out moisture.
Sticky Floors and Tight Doors
Tacky wood floors and doors that stick in summer both track with high humidity.

Frequently Asked Questions
Why does my San Antonio home feel clammy when the AC is running?
Your thermostat reads temperature, not moisture. Gulf dew points stay high here from spring into fall, so the air can hit 74 degrees and still hold enough water vapor to feel damp. We measure the actual relative humidity before recommending anything.
What indoor humidity level should we target in San Antonio?
We aim for the range the U.S. Environmental Protection Agency recommends: below 60 percent relative humidity, and ideally 30 to 50 percent. Above 60 percent, damp indoor air supports mold and dust mites. In our Gulf climate, holding that range through August is the real goal.
My air conditioner is new. Do I still need a dehumidifier?
Often, yes. Cooling equipment only removes moisture while it runs, and during our mild April and October stretches it barely runs at all. A whole house dehumidifier works off a humidity reading instead of the thermostat, so damp shoulder season days get handled.
Is a whole house humidifier worth it in San Antonio?
For most homes here, no. Whole home humidifiers are built for long cold dry winters, and ours are short and mild. During a hard freeze or a dry cold snap some homeowners do want one, and we install them. Dehumidification is the half that earns its keep locally.
Where does a whole home dehumidifier get installed locally?
Homes here do not have basements, so we work with the space the house gives us. That usually means the attic or a utility closet near the air handler, ducted so the unit treats the whole home rather than one room. We confirm placement during the visit.
Does humidity control help with cedar and oak pollen season?
Those are separate problems. Mountain cedar runs December through February and oak follows March through May, and pollen is a filtration question. We handle moisture with dehumidification and pollen with air filtration, purifiers, and duct cleaning, so ask about both.
