Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Air Duct Cleaning in Alamo Heights, TX
HVAC cleaning in Alamo Heights typically runs $380-$620 for a full system, and every job starts with a written price before we touch a single panel. The 1920s-1950s homes that define this neighborhood were built before central air was standard, so ductwork was retrofitted into attics and walls never designed for it - sagging flex runs, mismatched materials, and decades of accumulated debris that modern equipment struggles to reach. We dispatch from our San Antonio office and serve Alamo Heights with crews trained specifically for historic housing stock. Call (726) 600-7155 for a free written estimate.
Why Alamo Heights Homes Are Different
Most Alamo Heights homes were built between the 1920s and 1960s in Tudor Revival, Colonial, and early ranch styles - many with original plaster ceilings and finished attics that make duct access difficult and slow. HVAC systems were retrofitted long after original construction, so duct routing is often circuitous, with mismatched materials like early sheet metal elbows spliced to later flex duct that accumulate contaminants at every joint.
The San Antonio-Hill Country corridor produces some of the highest mountain cedar pollen counts recorded anywhere in North America each December through February, followed by Alamo Heights’ own dense live-oak canopy delivering a second heavy surge in March-April. Technicians working the 78209 zip regularly encounter original galvanized trunk lines hidden above intact plaster ceilings - homeowners accept the service cost but refuse ceiling access holes, so we often reroute flex duct through closets rather than cut historic finished surfaces.
Our Main Alamo Heights Services
Alamo Heights homeowners call us most often for these three services:
Air Duct Cleaning in Alamo Heights
We clean the full duct network - supply and return runs, trunk lines, and registers - using negative-pressure extraction (a vacuum system that pulls debris out while containing it) and rotary brush contact cleaning for stubborn buildup. In Alamo Heights, we photograph every run before and after because retrofitted systems often hide surprises: construction debris from 1980s HVAC additions, rodent nesting in abandoned chase ways, and pollen compaction at flex-to-metal joints. Air Duct Cleaning in Alamo Heights includes the full Documented Photo Record as standard.

Dryer Vent Cleaning in Alamo Heights
Dryer vent cleaning removes lint accumulation from the appliance through the exterior termination, measured with airflow meters before and after. Alamo Heights’ older homes often have longer vent runs through finished walls or roof terminations that complicate access and increase fire risk. We clean with rotary tools and inspect with a camera when the run exceeds 15 feet or has multiple elbows. Dryer Vent Cleaning in Alamo Heights includes written airflow readings in your job record.

Duct Repair & Sealing in Alamo Heights
Duct repair addresses disconnected runs, crushed flex, and failed sealing tape that leak conditioned air into attics and walls. In Alamo Heights, we regularly find original fiberglass duct board crumbling at plenum connections and 1990s flex duct sagging below insulation levels. We repair with metal-backed tape and mastic sealant, or replace damaged sections with new flex routed through accessible paths. Duct Repair & Sealing in Alamo Heights includes pressure-test verification where repair scope allows.

AfterHVAC Cleaning in Alamo Heights

Full HVAC Cleaning in Alamo Heights addresses the evaporator coil, blower assembly, condenser, and air handler - the components that move and condition air through your duct system. The retrofitted ductwork common to 1920s-1950s homes here creates negative-pressure imbalances that pull attic debris directly across these components, while the dual pollen peaks (mountain cedar December-February, live oak March-April) coat coils and blower fins with adhesive particulate that standard filter changes cannot prevent.
Evaporator Coil Cleaning
Signs you need it
Ice formation on refrigerant lines, weak airflow from registers, or cooling that cannot maintain set temperature during afternoon peaks.
What it costs in Alamo Heights
Evaporator coil cleaning typically runs $180-$340 depending on access difficulty and contamination level.
How we do it
We remove the coil access panel, apply foaming cleaner formulated for aluminum fins, rinse with low-pressure water capture, and photograph the coil surface before and after.
Blower Cleaning
Signs you need it
Vibration or noise from the air handler, uneven airflow between rooms, or dust streaking from supply registers.
What it costs in Alamo Heights
Blower assembly cleaning typically runs $160-$280 depending on motor type and debris accumulation.
How we do it
We remove the blower wheel and housing, clean blades and squirrel cage with compressed air and contact tools, balance the assembly, and document runout with a photo.
What HVAC Cleaning Costs in Alamo Heights
| Item | Typical range in Alamo Heights |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower assembly cleaning | $160-$280 |
| Full HVAC system cleaning (coil + blower + condenser) | $380-$620 |
How do I know my HVAC components are actually dirty?
We photograph every component before cleaning and deliver the images as part of your Documented Photo Record - if the coil or blower shows no significant debris, we show you and adjust scope before proceeding. Call (726) 600-7155 to schedule.
Can HVAC cleaning help with cedar fever symptoms?
Removing pollen-compacted debris from coils and blowers reduces recirculation of trapped mountain cedar and oak particulate, though it works best paired with sealed ductwork and upgraded filtration. Call (726) 600-7155 for a system assessment.
Air Quality & Sanitizing in Alamo Heights

Air Quality & Sanitizing in Alamo Heights targets the microbial and particulate load that retrofitted duct systems accumulate - mold in humid flex runs, bacteria on pollen-adhesive buildup, and odors from decades of organic material trapped in inaccessible corners. The 1920s-1950s housing stock here creates perfect conditions: slow airflow through oversized ducts, temperature differentials at metal-to-flex joints that produce condensation, and finished attics that prevent proper insulation and ventilation.
Mold Treatment
Signs you need it
Musty odor when the system cycles, visible growth at registers or in drip pans, or occupants with worsening respiratory symptoms indoors.
What it costs in Alamo Heights
Localized mold treatment typically runs $280-$480; whole-system treatment runs $450-$780 depending on duct access and contamination extent.
How we do it
We apply EPA-registered antimicrobial through the duct network using controlled fogging equipment, with dwell time verified and post-treatment air sampling where scope includes verification.
UV Light Installation
Signs you need it
Recurring mold despite cleaning, high microbial counts in air samples, or desire for continuous surface sanitation at the coil and drain pan.
What it costs in Alamo Heights
UV-C lamp installation typically runs $320-$550 for a single-lamp system, $480-$820 for dual-lamp coverage of coil and return.
How we do it
We mount a UV-C lamp in the air handler with sight-glass verification, wire to the blower circuit for automatic operation, and include the first replacement bulb in the installation record.
What Air Quality & Sanitizing Costs in Alamo Heights
| Item | Typical range in Alamo Heights |
|---|---|
| Localized mold treatment | $280-$480 |
| Whole-system mold treatment | $450-$780 |
| UV-C lamp installation (single) | $320-$550 |
Will UV lights actually prevent mold in my old ducts?
UV-C lamps sanitize surfaces they directly illuminate - the evaporator coil and drain pan - but do not treat the full duct network; we recommend them for chronic coil mold, not as standalone duct treatment. Call (726) 600-7155 for a scope recommendation.
Is the antimicrobial spray safe for my family?
We use EPA-registered products applied with controlled equipment, with recommended re-entry times documented in writing and the product SDS available on request per Haven Standard Clause 2. Call (726) 600-7155 for product specifics.

FAQs About Air Duct Cleaning in Alamo Heights

Standard residential duct cleaning and HVAC maintenance do not require permits in Alamo Heights; only structural modifications or new duct installation trigger permitting. We handle permit documentation when repair scope includes new duct runs or plenum modifications, included in your written scope.
We avoid cutting access holes through original plaster whenever possible, instead routing cleaning equipment and replacement flex through closets, utility chases, or existing access panels - documented in your photo record so you can verify no surfaces were disturbed.
We recommend HVAC cleaning in late October-November before mountain cedar peaks, or in May-June after oak pollen subsides - cleaning during peak season is effective but may show faster reaccumulation on your post-job photo record.
