Most of the homes around Broadway, Bluebonnet Hills, and the Avenues were built before 1960. That matters. The ductwork in these houses was installed when air conditioning was an afterthought, not a design priority. Cleaning them properly means understanding what 60-year-old galvanized duct runs actually look like from the inside, not just running a brush through and calling it done. We’ll get to that below.

Why Cardinal Air Duct Cleaning Is Alamo Heights’s Preferred Air Duct Cleaning Company

Alamo Heights homeowners are not new to home maintenance. You have a plumber, an electrician, probably a painter on speed dial. What you don’t have, usually, is a duct cleaner who shows you proof of the work. That’s where we come in. Our Air Duct Cleaning team operates under the Relay Visibility Guarantee, which is not a slogan. It’s a standard: live trackable arrival time, before-and-after photo documentation, and a digital invoice you can pay from your phone before we pull out of the driveway. No other duct cleaning company in Alamo Heights operates this way.

We’re part of the Relay Home Co. family, founded 2005, and every Cardinal location is independently owned and operated. This location is led by Omar Haddad, and Omar holds every job to one rule: written price first, source removal always, and a 365-day promise that if the work isn’t right, we come back and make it right. That’s not a conditional warranty. It applies to every booking, every time, no exceptions. Our technicians are background-checked and wear Cardinal uniforms. You’ll know the tech’s name before they ring the bell.

Air Duct Repair in Alamo Heights

Air Duct Repair in Alamo Heights usually means one of three things: a duct that has physically separated at a seam, a return plenum that has collapsed under decades of insulation weight, or a run that was never properly sealed in the first place. In pre-1960 ranch houses and bungalows, loose or disconnected ducts are surprisingly common. A gap of even half an inch at a joint means you’re paying to condition the attic, not the bedroom. Repair costs here typically land between $150 and $450 per affected section, depending on access and the condition of the surrounding sheet metal.

Sealing and Reconnecting Older Runs

When we find a separated duct in an Alamo Heights home, we do not tape it and leave. The joint gets mechanically reconnected, sealed with mastic or a UL-listed sealant, and photographed before and after. If the sheet metal itself is rusted through or crushed, we quote a replacement section and show you the damage on camera. No mystery pricing, no “we’ll see when we get in there.”

Return Plenum Repair on Pre-1960 Systems

Older homes near Cambridge Oval and along Arcadia often have return plenums built from thin, unlined metal. After 60 years, those plenums sag, leak, and pull attic air directly into your system. We assess the plenum during every cleaning, and if it needs repair, you get a written line-item price before any cutting starts. Repairs are covered by our written guarantee, and if the fix fails within a year, a second visit is free.

Ductwork Cleaning in Alamo Heights

Ductwork Cleaning in Alamo Heights is different from what a fly-by-night operation will sell you over the phone. The honest version is a full system cleaning: supply ducts, return ducts, registers, the air handler cabinet, and the blower motor compartment. In older Alamo Heights homes, the return side is almost always the dirtiest zone, because return ducts run negative pressure and pull air from every gap, crack, and wall cavity they pass through. A typical full ductwork cleaning here runs $350 – $600, with larger homes or systems with extensive buildup on the higher end.

Source Removal, Not Surface Vacuuming

We use negative-pressure extraction, which means the loosened debris goes straight into a HEPA-filtered collection unit rather than back into your living room. Our trucks carry Rotobrush agitation systems and Nikro HEPA vacuums, plus Abatement Technologies containment units when a job calls for it. The process loosens caked-on debris, pulls it out under vacuum, and leaves the duct interior visually verifiable. You see photos of your own ducts, not stock images.

Air Handler and Blower Access

Plenty of crews never open the air handler. That’s a mistake, especially in Alamo Heights homes where the blower compartment can hold a decade of accumulated dust even when the branch ducts look passable. Every Cardinal cleaning includes air handler access. If your blower wheel is caked, we clean it. If the evaporator coil is fouled, we tell you and document it. These are the things that actually move dust through your house.

Trusted Brands We Service in Alamo Heights

We work on systems built around equipment from Trane, Carrier, Lennox, Rheem, and Goodman, and we do not push replacement parts you don’t need. When filtration upgrades make sense for an Alamo Heights home, we carry and install products from Aprilaire, Honeywell, and Guardsman. For cleaning equipment, we rely on Rotobrush rotary brush systems and Nikro HEPA-rated vacuums, the same professional-grade tools used by commercial duct cleaning contractors. If your system uses a specific filter size or a specialty register style common to older Alamo Heights construction, we’ll arrive with what’s needed or source it same week from our San Antonio suppliers.

Common Air Duct Cleaning Problems We See in Alamo Heights Homes

• Dense return-side buildup. In older Alamo Heights houses, the return plenum and return trunk lines collect a felt-like mat of dust, pet hair, and skin cells that a standard filter never catches. This is the single most common cause of persistent dust film on furniture near Cambridge Oval and the Avenues.
• Leaky, unsealed 60-year-old duct runs. Original galvanized trunk-and-branch systems from the 1950s and 1960s were rarely sealed at the seams. That means attic insulation, dust, and humidity get pulled directly into the conditioned air path. Cleaning alone won’t fix leaks, but we’ll identify and photograph every separation we find.
• Collapsed or crushed flex runs in later additions. Many Alamo Heights homes have original rigid ductwork in the main house and flex duct added during later renovations. The flex sections deteriorate faster, especially in Texas attic heat, and we often find them kinked or crushed, starving rooms of airflow.
• Unbalanced supply and return airflow. Older Alamo Heights floor plans, especially the ranch styles east of Broadway, often have too few return registers. That creates negative pressure zones that pull dust through wall cavities and door gaps. We’ll tell you honestly whether duct cleaning will help or whether the deeper issue is return sizing.
