Air Duct Services
Scope set by inspected condition — repair, mastic-seal, sanitize, or replace, never more than needed.
Learn moreMold and bacteria on the HVAC coil get circulated to every room in the house. We install UV-C lamps in the plenum to neutralize them at the source, chemical-free — and the install detail that matters is positioning: the lamp has to be sized and aimed to actually irradiate the coil surface, or it does nothing. We set it to do that, and track annual bulb replacement since UV output fades over time, so the sanitization stays effective rather than just installed.

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. TCE designs and installs whole-home IAQ as a diagnosed, deliberate package, matched to your home, your climate, and your sensitivities, and verified with before-and-after measurement. It's the measured approach to a category flooded with overpromised plug-ins.
The honest version of IAQ starts with diagnosis. Particulate, VOC, CO2, and humidity are sampled, because you should know what's actually wrong before anyone sells you a solution. From there the system is built in layers, each chosen for a measured 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 TCE 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.
This hub spans IAQ testing and diagnosis; 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 diagnosed next step once an air duct cleaning (D1) and sealing (D2) have given you a clean, tight system to build on.
Because TCE is national and standards-driven, the diagnostic-first methodology and the verification are identical in every market — an IAQ package in Phoenix is designed and proven exactly as one in Houston. You're not trusting a local outfit's favorite gadget; you're getting an engineered system from the brand that earned its name on premium work. The premium 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 standard is condition-driven, not calendar-driven: NFPA 211 ties cleaning to a measured 1/8" of creosote accumulation, and a Level 1 inspection is the way we confirm you've reached it. For a wood-burning fireplace in regular use that typically lands at once per heating season — but we measure the buildup and tell you what the flue actually shows rather than assuming.
Yes — and verifiably so. Our inspectors hold current CSIA (Chimney Safety Institute of America) certifications you can confirm yourself in the CSIA member directory at csia.org, and our fireplace work is handled by NFI specialists. We name the standard we inspect to so you can check the credential behind the report.
Yes. We respond 24/7 (subject to crew availability) to the situations that can't wait for a diagnosis later — an active water leak into the home, an animal trapped in the flue, post-fire hazards, and storm damage. We make the system safe first, then document the cause; same-day in most cases.
Always — and with the evidence attached. Before any work starts you receive a written quote backed by photos of exactly what we found and why it needs attention. Final pricing follows the documented condition of the chimney and anything the inspection turns up, not a number guessed before we've looked.
Flue Watch is our annual maintenance plan at $19.99/month ($240/year): a documented Level 1 inspection and sweep every year ($248 value), priority scheduling, 10% off all repairs, and emergency-response priority. It's the way to keep a year-over-year record of your system's condition. Cancel anytime, no contract.
