We are Cardinal Air Duct Cleaning, part of the Relay Home Co. family founded in 2005. Our Houston crew works across the metro every week, from Meyerland ranch houses built in the Kennedy era to brand-new flex-duct systems going up out in Katy. Houston housing stock is not one thing, so we do not treat it like one thing. More on that below.

Why Cardinal Air Duct Cleaning Is Houston’s Preferred Air Duct Cleaning Company

Houston homeowners keep calling us back for one reason: we show proof. Every job includes before-and-after photographs of your own ducts, taken with our inspection cameras. Not stock images. Your actual supply and return runs, photographed so you can see what was in there and what is left. That is the Relay Visibility Guarantee, and it applies to every booking without exception.

Omar Haddad leads the Houston team, and he holds every job to a standard most companies will not put in writing. The 365-Day Done Right Promise means if the work is not right within a full year, we return and correct it at no charge. That covers the entire cleaning, not just select items. We also put a written guarantee on every repair and include a free second visit if a repair fails. Those are not marketing lines. They are the terms on your invoice.

Response time to Houston neighborhoods is straightforward: when you book, you get a live trackable arrival time through The Relay Standard. You will know the technician’s name before they knock, and that technician arrives in uniform, background-checked, driving professional equipment. Nikro HEPA vacuums handle extraction. Rotobrush agitation systems break debris free from trunk lines and flex runs alike. No truck-mounted shop-vac shortcuts, ever.

How Houston’s Housing Stock Changes Duct Cleaning

Here is what most national duct cleaning websites will not tell you, because they are built to be copy-pasted across fifty cities. Houston’s mix of 1950s-era slab-foundation ranch homes and newer Energy Star construction means the duct challenges differ block by block. Older homes in places like Meyerland, Westbury, and Oak Forest often have undersized galvanized trunk-and-branch systems with disconnected joints, rusted seams, and decades of settled dust packed into horizontal runs. Newer construction in Katy, Cypress, and Pearland is almost entirely flex duct run through 140-degree attics, where sagging, kinking, and condensation inside the liner are the real problems. Each requires a different cleaning approach, different pressure settings, and different agitation tools. No single duct cleaning method covers Houston’s housing stock, and any company that says otherwise is guessing at your expense.

We saw this play out on a 1962 ranch in Meyerland recently. The homeowner was running the blower motor constantly and still getting dust on every surface. Using agitation tools and negative pressure with HEPA filtration, we pulled over a decade of debris from the supply and return ducts and found two disconnected joints in the attic run that were dumping unfiltered air straight into the living space. The before-and-after photographs of the ducts, always part of our flat-rate service, showed the homeowner exactly why the blower motor had been overworked. We added a Guardsman access panel at the air handler for future camera inspection. That is what an honest duct cleaning in Houston actually looks like.

Air Duct Inspection in Houston

Air Duct Inspection in Houston is where we start when a homeowner is not sure what they are dealing with: unexplained dust, allergy flare-ups, rooms that never reach temperature, or musty air when the AC kicks on. We run a push-camera through the supply and return runs and show you the footage live on a screen. No mystery. You see exactly what we see, and you decide what happens next.

Camera-Aided System Review

We inspect the trunk line, branch runs, plenum connections, and air handler. In Houston’s humid climate, we are specifically looking for condensation inside flex duct, microbial growth on the liner, and disconnected joints. A camera inspection on a typical Houston home runs $150 – $250, and that fee is waived if you move forward with a full cleaning.

When an Inspection Precedes a Cleaning

Newly purchased homes in Houston should get an inspection before move-in. Previous owners rarely clean ducts, and in a hot, humid attic, years of accumulated dust can smell and circulate. We recommend inspection for any Houston home you have lived in longer than four years and have never had cleaned.

Residential Air Duct Cleaning in Houston

Residential Air Duct Cleaning in Houston is our core service, and it is a full-system job, not a register vacuuming. We clean the supply ducts, return ducts, trunk lines, branch runs, plenums, and the air handler interior. The job uses agitation tools to break debris free from duct walls, paired with negative-pressure extraction, which means loosened particulate goes straight into the HEPA-filtered vacuum, not back into your living room.

One Flat Price for the Whole System

This is the part where Houston homeowners have been burned. Some companies quote per vent, so a 22-vent home in Katy costs twice as much as an 8-vent bungalow in the Heights, even though the cleaning method is identical. We do not do that. You get one written flat price for the entire system before we begin, and it does not change at the door.

What the Cleaning Actually Involves

We access the trunk line, insert agitation tools to dislodge settled debris, and run negative-pressure extraction with Nikro HEPA filtration throughout the cleaning. Every supply and return register is sealed or cleaned. If we open a wall or ceiling access point during the job, we leave Guardsman access panels, not a hole. Most standard Houston homes run $450 – $800 for the full system.

Trusted Brands We Service in Houston

Our Houston crews work on systems from every major HVAC brand, and we stock common replacement filters and access panels locally for Houston customers. When we install filtration, we use Aprilaire and Honeywell products, matched to your system, not a generic big-box filter cut down to fit. For containment and extraction on heavier jobs, we rely on Abatement Technologies units. Fast turnaround on parts means a repair that would take another company a week often takes us a day or two.

Common Air Duct Cleaning Problems We See in Houston Homes

• Disconnected joints in attic runs. This is the failure we find most often in Houston’s older slab-foundation homes. Galvanized duct sections slip apart over decades, and your blower pushes conditioned air into the attic instead of your living room.
• Mold and moisture in flex duct. Houston attics routinely hit 140 degrees, and when humid air meets the cooler liner of a sagging flex duct, condensation forms. That moisture supports microbial growth that you then breathe every time the AC runs.
• Decades of construction debris. Many Houston homes were built during fast-growth boom years, and drywall dust, paint flakes, and even fast-food wrappers from the construction crew end up inside the ducts before the first owner moves in.
• Clogged return ducts from pet dander and candle soot. Houston homes with indoor pets and frequent candle use will see a thick, sticky film on return duct walls. This film traps more dust and reduces airflow, especially in older ranch homes with undersized returns.
