Indoor air quality · fix the symptom, not just the smell

Indoor air quality services in College Station and the Brazos Valley.

Most indoor air problems aren't fixed with a plug-in purifier or a stronger fragrance. They're fixed by addressing what's actually wrong — usually filtration, humidity, ventilation, or duct leakage. We diagnose before we recommend, so you don't pay for a UV lamp when the problem was actually a return-side duct leak.

What's typical

Indoor Air Quality — scope & pricing.

Six common variants of indoor air quality we see most often in the Brazos Valley, with indicative ranges.

MERV filter upgrades

$300 – $600

Higher-MERV filters trap more particulates. Verified that your system can handle the pressure drop.

UV lamp install

$500 – $900

Coil-mounted UV-C kills mold growth on the evaporator coil — the actual source of musty smells in many homes.

Whole-home dehumidifier

$1,500 – $2,500

Real fix for chronic high indoor humidity in Texas. Plumbs into your existing ductwork.

Whole-home humidifier

$800 – $1,500

For dry winter air. Less common in Texas but valuable in some homes.

Fresh-air ventilation (ERV/HRV)

$1,500 – $2,500

Controlled outdoor air for tightly-sealed modern homes. Reduces CO2 and indoor pollutant buildup.

Duct sealing (when that's the real fix)

Often what 'IAQ' problems actually need.

When to call

  • Persistent allergy or asthma symptoms inside
  • Musty smell when AC kicks on — usually coil mold

  • New baby, immunocompromised resident, or pet allergies driving the question
How it goes

Our indoor air quality process.

01

Assessment visit

We diagnose what's actually causing the issue. Often the answer isn't an add-on — it's fixing duct leaks or replacing a 1-inch filter with a 4-inch filter cabinet.

02

Recommended scope

If an IAQ product is genuinely the right answer, we recommend the specific component. If duct sealing is the real fix, we recommend that instead.

03

Install

Most IAQ component installs are half-day. UV lamps and filter cabinets are typically a few hours.

04

Verification

Where applicable, we verify the system is performing — humidity readings, airflow checks, etc.

Questions

About indoor air quality.

Sometimes. UV-C on the evaporator coil kills mold growth on the coil — which is the source of most musty AC smells. But if the smell is coming from somewhere else (water damage, return-side duct leaks, etc.), a UV lamp won't help. We diagnose first.
True HEPA-rated filters usually aren't installable in residential HVAC systems because of the pressure drop. MERV 13–16 filters offer a meaningful upgrade without choking the system — we verify your equipment can handle the resistance before recommending.
If your indoor humidity stays above 60% even with the AC running, yes — a whole-home dehumidifier is the right fix. If humidity is only a problem at low-cooling-load times (mild days, fall, spring), a variable-speed AC may solve it without a separate dehumidifier. We measure before we recommend.
Standard 1-inch filters: every 30–60 days during heavy use. 4-inch media filters: every 6 months. If you have pets or allergy sensitivities, on the shorter end. A maintenance plan includes filter changes.
