Drier, Healthier Comfort in the Rio Grande Valley
Whole-House Dehumidifier Installation & Service
RGV heat + humidity can make rooms feel sticky even when the AC is running. A whole-house dehumidifier keeps indoor relative humidity in the 40–55% sweet spot, reducing musty odors and mold risk, protecting wood floors and furnishings, and making your home feel cooler at a higher thermostat setting. Treviño Repairs sizes, installs, and integrates dehumidifiers with your existing HVAC—clean ducting, safe condensate drainage, proper power, and professional commissioning—so your space stays comfortable without overworking the AC.
Balanced Humidity, Better Comfort—RGV Wide
Services for Whole-House Dehumidifiers
We design and install dehumidification that fits your home and system—not just a portable stopgap. After a quick review of latent load (square footage, occupants, infiltration) and airflow/static pressure, we plan a clean, code-compliant install with dedicated return/supply ducting (or supply tie-in), safe condensate routing, and the right control strategy. On install day we protect the work area, set the unit, wire power/controls, commission to spec, and walk you through simple maintenance.

- Whole-house dehumidifiers (approx. 70–200+ pints/day)
- Dedicated return & supply ducting or supply tie-ins with balancing dampers
- Wall humidistats or smart-thermostat integration; remote sensors (as applicable)
- Condensate management: gravity drains, traps, pans, pumps, float safeties
- Fresh-air ventilation kits (select models) for dry, tempered makeup air
- Filter/media changes, cleanouts, and performance checks
Integration & code items (as applicable):

Upgrades & options:

Whole-House vs. Portable Dehumidifiers — RGV Guide
Whole-house dehumidifiers connect to your HVAC ducts and treat the entire home with higher capacity, better efficiency, and quieter operation—automatically maintaining 40–55% RH without buckets to empty. They can run without the AC on mild, sticky days and integrate with fresh-air kits to dry incoming air. Portable units are low-cost and room-specific, but they’re louder, add heat to the room, require frequent tank emptying, and rarely address humidity evenly across the home. In our humid RGV climate, a ducted whole-home system delivers steadier comfort, protects finishes, and often reduces AC runtime.

When to Install or Upgrade a Whole-House Dehumidifier
Indoor humidity over 60%, rooms that feel clammy at normal temps, musty odors, window or vent condensation, cupping wood floors, visible mold/mildew, sweaty supply registers, frequent AC cycles with poor comfort, or allergy/respiratory irritation are strong indicators it’s time for whole-home dehumidification. Treviño Repairs can measure RH and static pressure, evaluate returns/ducts, and recommend a right-sized system with safe drainage and simple controls for your RGV home or business.

Will call again if I have other electrical problems.Posted on Jennifer CastilloTrustindex verifies that the original source of the review is Google. Great Service: We had a leak and couldn’t figure out where it was coming from. Eduardo took his time to find the source, kept me updated throughout the process, and finally discovered it was an AC leak. Just last week, we had paid another company to fix the same issue, but they didn’t do the job correctly. Eduardo explained everything clearly, offered to correct the problem, and even charged less than what we had previously paid the other company. Once he identified the leak, he made sure it was completely taken care of. I called today, and they arrived in less than an hour—excellent service! Eduardo was the best, and I highly recommend him company.Posted on JoAnn BreauxTrustindex verifies that the original source of the review is Google. Great service, super fast and convenient.

Whole-House Dehumidifier Questions, Answered
Straightforward answers before you book—symptoms, costs, fixes.
What RH should I target?
Most homes feel best at 40–55%. We’ll set an RH that balances comfort, mold prevention, and energy use for your space.
Will a dehumidifier lower my AC bills?
Often. By removing moisture directly, you can stay comfortable at a slightly higher thermostat setting and reduce AC runtime—especially on mild, humid days.
Where does the unit go—and how loud is it?
Common locations are attics, mechanical closets, or garages (with insulated/ducted connections). Whole-home units are typically quieter than portables because the fan is remote and ducted.
Do I need a new thermostat or control?
Not necessarily. We can use a wall humidistat, integrate with many smart thermostats, or provide a dedicated controller—whatever fits your system and preferences.
What maintenance is required?
Replace/clean the unit’s filter on schedule, keep drains clear, and check the pump/pan if installed above finished spaces. We’ll label intervals and review simple upkeep.
