Indoor Air Quality

In this climate, air quality usually starts with humidity.

Filtration gets the attention, but the complaints people actually describe here — musty smell, clammy rooms, condensation on vents, dust that returns immediately — are more often a moisture or an airflow problem than a filter problem. We measure before recommending equipment, because the wrong device fixes nothing and runs forever.

What you get

What the visit actually includes.

Measurement first
Indoor relative humidity and temperature, static pressure, filter restriction, and where outside air is actually entering the house.
Filtration that fits the system
Filter selection is a trade-off between capture and airflow. A high-MERV filter in a system that cannot pull through it makes the whole system worse. We size the filter housing to the airflow, not to the marketing.
Humidity control
Options range from thermostat and equipment staging changes through to a dedicated dehumidifier tied into the duct system, depending on what the readings show.
Ventilation and pressure
Where a house is pulling air from matters. A home under negative pressure draws humid, unconditioned air in through every gap it has.
Source correction
Blocked drains, wet insulation, disconnected returns in an attic, and duct leakage are corrected as causes rather than masked with an air cleaner.

How we work

The sequence, every time.

Describe the symptom
Where in the house, at what time of day, and what makes it better or worse. Air quality complaints are highly locational and the pattern is diagnostic.
Take readings
Humidity and pressure across the house, not a single number at the thermostat.
Identify the mechanism
Moisture entering, moisture not being removed, air not moving, or air being filtered badly. These have different fixes and different costs.
Recommend in order of leverage
The cheapest effective change first. Equipment only where the measurements justify it.

Gulf Coast specifics

Why this work is different here.

Salt air, humidity, attic temperatures and a cooling season that runs most of the year. All four change what fails, how early, and what is worth doing about it.

Target humidity is a real number
Indoor relative humidity that sits consistently above the mid-fifties is where comfort, odour and material problems begin. It is measurable, which means it is manageable.
Short-cycling oversized equipment
An oversized system satisfies the thermostat before the coil has run long enough to condense much moisture. The room is cold and the air is wet — the most common complaint on this coast, and it is a sizing problem.
Closed-up seasonal homes
A house left at a high setpoint in July with no humidity strategy can develop a mould problem in weeks. Controls that hold humidity rather than temperature exist for exactly this.
Salt, pollen and construction dust
Coastal and seasonal loading on filters is heavier than most people expect, and a filter left in past its interval becomes an airflow restriction.

Questions

About indoor air quality

(239) 555-0142

Do I need duct cleaning?

Sometimes, and less often than it is sold. It is worth doing after construction work, after a rodent or moisture event, or when there is visible contamination. Routine duct cleaning on an otherwise healthy system rarely changes anything measurable.

Are UV lights worth it?

They have a legitimate, narrow use — keeping the evaporator coil clear of biological growth. They do not sterilise a house, and we will not present one as though it does.

What humidity should I be aiming for?

Broadly, keeping indoor relative humidity in the forties to low fifties is where most people find the house comfortable and where moisture problems become unlikely. Getting there is usually about run-time and equipment staging, not about buying a gadget.
