Indoor Air Quality — Filtration, Ventilation & Humidity Control
Clean, fresh air starts with the right mix of filtration, ventilation, and humidity control. Treviño Repairs assesses your system’s airflow and static pressure, then installs right-sized upgrades—high-MERV media filtration (and HEPA add-ons), ERV fresh-air ventilation, whole-home dehumidification, and UV coil treatment when appropriate—so your RGV home or business feels cleaner, smells fresher, and stays comfortable without overworking the AC.
Whole-Home Solutions, Not Just Gadgets
Services for Indoor Air Quality
We design and install IAQ systems that solve real problems—dust, odors, high humidity, stuffy rooms—while protecting airflow and efficiency. After a quick airflow/static check, we match components to your equipment and layout, then install cleanly with proper drains, wiring, and controls.
We install & service:
- High-MERV media cabinets (typically MERV 11–16) & HEPA bypass add-ons
- Fresh-air ventilation (ERV; HRV where appropriate), motorized dampers
- Whole-home dehumidifiers with dedicated returns/supplies & drain/pump
- UV/UV-C coil treatment (keeps the coil cleaner; helps odor/microbial growth on surfaces)
- Return air adds, duct sealing, and balancing for better airflow & pressure
- Smart thermostats/IAQ controls and indoor air quality monitors (wiring/installation)
Code & best practices (as applicable):
- Static-pressure review so filters/HEPA don’t choke airflow
- Correct outside-air intake location, backdraft prevention, and damper control
- Proper condensate traps/drains (with safeties) for dehumidifiers & ERVs
- Dedicated circuits and GFCI/AFCI protection where required
- Tight, sealed duct connections and labeled service access
Filtration vs. Ventilation vs. Dehumidification — RGV Guide
Filtration removes particles already inside: dust, pollen, pet dander, and many smoke/traffic particles (higher MERV = finer capture). Use a media cabinet to gain efficiency without spiking static pressure; add HEPA bypass when allergies are severe.
Ventilation (ERV/HRV) brings in measured outdoor air to dilute indoor pollutants and odors. In the humid RGV, an ERV is usually preferred—it helps manage incoming moisture compared to an HRV.
Dehumidification keeps indoor RH in the 40–55% sweet spot, curbing musty odors and mold risk while making rooms feel cooler. It also reduces AC runtime on mild, sticky days when cooling demand is low.
UV coil treatment helps keep the indoor coil cleaner and can reduce odor/microbial growth on coil surfaces; it’s a maintenance helper, not a stand-alone purifier.
Treviño Repairs sizes and stages these pieces so they work together—good air in, bad air out, and moisture under control.

When to Upgrade Indoor Air Quality
Dust that settles quickly after cleaning, persistent musty odors, indoor humidity over 60%, condensation on windows, visible mold, stuffy rooms or headache/fatigue in occupied spaces, dirty supply registers, frequent coil slime/clogged AC drains, or rising energy bills from humidity load are all signals to act. We’ll test airflow and RH, review filter/return sizing, and recommend the right mix of filtration, ventilation, dehumidification, and coil treatment for your RGV property.
What to Expect with Treviño Repairs
Our Indoor Air Quality Upgrade Process
Assess & Measure. Discuss concerns; check filters, returns, ducts; measure static pressure, temperature/RH, and (when helpful) CO₂.
Plan & Options. Right-size solutions (media cabinet/HEPA, ERV, dehumidifier, UV coil) with clear pricing and what each solves.
Protect & Prep. Shoe covers, drop cloths, safe shutoffs, layout marks, and mounting locations.
Install Components. Set media cabinet/HEPA, ERV with proper intake/exhaust and dampers, dehumidifier with dedicated return/supply and drain, and UV coil light when appropriate.
Wire & Drain. Add dedicated circuits where needed; route/trap drains with safeties; integrate basic IAQ controls.
Commission & Balance. Verify airflow/static, set ERV ventilation rate, confirm dehumidifier RH setpoint, check temperatures and condensate flow.
Clean Up & Walkthrough. Tidy the area, label filters/lamps, review maintenance intervals, and provide simple care tips for RGV heat and humidity.
Real Stories. Real Results.
What Our Customers Are Saying
Indoor Air Quality Questions, Answered
Straightforward answers before you book—symptoms, costs, fixes.
What MERV rating should I use?
Most homes do well with MERV 11–13 in a media cabinet; go higher (MERV 16/HEPA bypass) for allergies—as long as static pressure stays in range. We’ll measure and size accordingly.
ERV or HRV—what’s right for the RGV?
Typically ERV. It helps temper incoming humidity, which suits our climate. HRV can fit cooler/drier regions or specific applications.
Will a whole-home dehumidifier lower my AC bills?
Often, yes. Controlling humidity reduces “sticky” discomfort and lets the AC run less on mild, humid days—improving comfort and protecting finishes.
Does UV kill germs in my home’s air?
UV coil lights primarily keep the coil surface cleaner and help with odors/microbial growth there. They’re a maintenance aid; pair them with filtration/ventilation for air improvements.
How often should I change filters and service equipment?
Media filters: typically 3–6 months (usage dependent). HEPA/ERV/dehumidifier: follow the manufacturer—expect annual checks, lamp changes for UV, and periodic drain cleaning. We’ll label schedules and show you the basics.
