Air Duct Services
Beyond cleaning — duct repair, mastic sealing, sanitizing, and replacement.
Learn moreYour HVAC coil is dark and damp, which makes it a quiet breeding ground for mold and bacteria that then ride the airstream through the whole house. UV-C lamps in the plenum neutralize that mold, bacteria, and viruses right at the source, chemical-free, and we handle the annual bulb replacement too. It's a smart companion to a duct cleaning — clean the ducts, then keep them clean — and the same crew sets up both in one visit so your indoor air stays healthier year-round.
Clean ducts are the start of indoor air quality, not the finish. The air your family breathes is shaped by what you filter, what you ventilate, what you de-humidify, and what you sterilize — and those are engineered systems, not gadgets you clip on and hope. Texas Service Experts designs and installs whole-home IAQ as a deliberate package, matched to your home, your climate, and your sensitivities, and verified with real measurement. It's the whole-home approach to a category flooded with overpromised plug-ins — and since the same crew already cleaned your ducts and dryer vent, the air quality system is built on a clean, tight foundation by the people who put it there.
Diagnosis is where the honest version of IAQ starts. We sample particulate, VOC, CO2, and humidity, because you should know what's actually wrong before anyone sells you a solution. From there the system gets built in layers, each chosen for a reason. Filtration: a 4-to-5-inch deep-pleat media cabinet cut into the return, or a true-HEPA bypass, or an electronic air cleaner — replacing the thin one-inch slot that protects the equipment but not your lungs, with the filter rack sealed so air can't bypass the media. Sterilization: a UV-C germicidal lamp at the coil to kill the mold and bacteria that grow on a wet evaporator, or an in-duct PCO/ionization purifier (REME-HALO, iWave) that pushes oxidizers into the living space to neutralize odors, VOCs, and pathogens at the source. Humidity: a ducted whole-home dehumidifier to pull the moisture that drives mold and discomfort, or a bypass humidifier for dry heating months. Ventilation: an ERV or HRV that brings balanced fresh air into a tight home while recovering the energy, or a controlled fresh-air intake with a motorized damper to meet code ventilation without a humidity penalty.
The TSE difference is that we engineer the combination rather than sell you a shelf. A UV lamp on a system with a starved return is a band-aid; a dehumidifier on a leaky duct system fights itself. We look at filtration, sterilization, humidity, and ventilation together, and we'll tell you which layers your home actually needs and which it doesn't — including saying no to the ones that wouldn't earn their keep. Then we install to a finish standard, wire the accessories to the air handler and a communicating or smart thermostat so the system runs as one, and verify the result by re-sampling particulate, VOC, and humidity so the improvement is documented, not assumed.
IAQ testing and diagnosis anchor this hub, along with media, HEPA, and electronic air-cleaner cabinet installs; MERV upgrades with filter-rack sealing; UV-C germicidal lamp installation; in-duct ionizer and PCO purifier installs; whole-home dehumidifier and humidifier installs; ERV/HRV and fresh-air-intake ventilation; zoning systems where comfort and air distribution call for it; and the smart-thermostat integration that ties it together. It's the natural next step once an air duct cleaning (D1) and sealing (D2) have given you a clean, tight system to build on.
Because it's one standards-driven crew, the diagnostic-first method and the verification are consistent every time — and it's the same team that cleaned your ducts, swept your chimney, and cleared your dryer vent. You're not trusting a separate outfit's favorite gadget; you're getting an engineered system from the whole-home crew that already knows your house. The value is the engineering discipline and the before/after measurement: cleaner air you can actually verify, not a device on the wall you hope is doing something.

Family-owned, CSIA-certified, NFPA 211–compliant. We're the team you call when you want it done right the first time — no rotating subcontractors, no upsell pressure, no surprises. Same techs, same trucks, same standard.

The NFPA recommends a Level 1 inspection every year, with a sweep once buildup reaches 1/8" of creosote — for a wood fireplace you actually use, that's about once a heating season. The neighborly part: since we're already on the roof, the same crew checks your dryer vent and caps the visit with a quick whole-home safety look, so one appointment covers what would otherwise be three.
Yes — our inspectors hold current CSIA (Chimney Safety Institute of America) certifications, verifiable in the CSIA member directory at csia.org, and we have NFI specialists for fireplace work. The same trained crew handles your chimney, fireplace, dryer-vent and air-duct needs, so you're not juggling four different contractors for one house.
Yes — 24/7 response (subject to crew availability) for active leaks, an animal trapped in the flue, post-fire damage, and storm damage, same-day in most cases. One call reaches one crew that can handle whatever the situation turns out to need, instead of bouncing you between specialists while the water's still coming in.
Always — a written quote before we lift a tool, with photos of what we found, so you see exactly what you're approving. If the same visit turns up something in the dryer vent or ducts, it goes on one itemized quote and one invoice rather than a string of separate trips.
The Whole-Home Care Plan is our annual maintenance plan at $19.99/month ($240/year): a Level 1 inspection and sweep ($248 value), priority scheduling, 10% off all repairs, and emergency-response priority. Because one crew covers chimney, fireplace, dryer-vent and ducts, the plan keeps the whole house on a single schedule instead of a calendar full of separate service calls. Cancel anytime, no contract.
