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 Kirby, TX
Complete HVAC cleaning in Kirby typically runs $380-$680 for a whole-home system, with most jobs scheduled within a week and finished in one day. The 1950s-1970s ranch and tract homes that dominate this 1.2-square-mile enclave were built with ductwork standards that predate modern sealing, and Bexar County’s 140°F summer attic temperatures accelerate the deterioration that makes professional cleaning necessary. We dispatch crews from our San Antonio office to Kirby daily; call (726) 600-7155 for a written estimate before any work begins.
Why Kirby Homes Are Different
Kirby sits entirely inside San Antonio’s city limits, a 1.2-square-mile island with no room to expand and a housing stock frozen in the post-WWII era. The ranch and tract homes near FM 78 and I-10 East were built between 1950 and 1975, many with original flex duct or a single replacement that is now itself failing. Attic temperatures here routinely exceed 140°F for months at a time, baking duct liners and drying mastic joints until they crack.
The rental concentration along the I-10 East corridor means many properties have seen successive tenants for 40-50 years with no landlord-mandated duct maintenance. Technicians regularly find debris loads consistent with original 1960s installation, including old insulation materials no longer manufactured. Caliche dust from Bexar County’s alkaline soil, combined with 8-9 months of continuous cooling operation, drives fine particulate deep into metal trunks that were never designed for modern filtration.
Our Main Kirby Services
Homeowners in Kirby call us most often for these three services, each with its own dedicated page and pricing:
Air Duct Cleaning in Kirby
We clean the full duct network in Kirby’s older homes: metal trunks, flex runs, plenum boxes, and registers, using negative-pressure extraction with Rotobrush contact agitation. Every job includes a Documented Photo Record of each duct run, before and after, because in this market we regularly find systems that have not been opened in 20-30 years. Air Duct Cleaning in Kirby covers whole-home pricing and what we typically find in local attic systems.

Dryer Vent Cleaning in Kirby
Dryer vents in Kirby’s 1950s-1970s construction often run through unconditioned attic spaces or exterior walls with original terminations that do not meet current code. We remove lint buildup with professional-grade extraction tools and verify airflow at the termination point. Dryer Vent Cleaning in Kirby details our process for these older vent configurations.

Duct Repair & Sealing in Kirby
Failed mastic joints, torn flex duct, and disconnected plenum connections are standard findings in Kirby’s aging stock. We repair with code-compliant materials and seal to modern standards, photographing every connection before closing the attic. Duct Repair & Sealing in Kirby explains our repair scope and material specifications.

Before
AfterHVAC Cleaning in Kirby

HVAC cleaning in Kirby addresses a specific problem set created by this enclave’s housing era and climate. The evaporator coils, blowers, and condensers in these 1950s-1970s systems work against 8-9 months of continuous cooling load, often with filters that were upgraded to higher MERV without matching blower capacity, which overloads the coil with restricted airflow. Our HVAC Cleaning service covers the full mechanical system, not just the duct network.
Evaporator Coil Cleaning
Signs you need it
Ice formation on refrigerant lines, weak airflow from registers, or cooling that cannot hold setpoint during Bexar County’s July-September peak loads.
What it costs in Kirby
Evaporator coil cleaning in Kirby typically runs $180-$340, depending on access panel configuration and contamination level.
How we do it
We remove the coil assembly when accessible, apply foaming cleaner formulated for aluminum fins, rinse with low-pressure water, and document the before-and-after condition with photos delivered as part of the job record.
Blower Cleaning
Signs you need it
Vibration at startup, uneven airflow between rooms, or a motor amp draw that exceeds manufacturer specification due to dust loading on the squirrel cage.
What it costs in Kirby
Blower assembly cleaning in Kirby typically runs $160-$290, with variable-speed motors at the higher end due to electronic component protection requirements.
How we do it
We remove the blower housing, clean the wheel and motor housing with compressed air and contact tools, balance the assembly, and verify amp draw against the nameplate before reinstallation.
What HVAC Cleaning Costs in Kirby
| Item | Typical range in Kirby |
|---|---|
| Evaporator coil cleaning | $180-$340 |
| Blower assembly cleaning | $160-$290 |
| Condenser coil cleaning | $140-$260 |
How do I know if my HVAC system needs cleaning or just the ducts?
If the registers blow weak or warm air despite clean ducts, the restriction is likely at the coil or blower, not the duct run. We inspect both during our initial assessment and quote each component separately in writing.
Can HVAC cleaning fix my high summer electric bills in Kirby?
Dirty coils and blowers can increase energy consumption 15-25%; cleaning restores designed airflow and reduces run time. Call (726) 600-7155 for a written estimate - we measure before-and-after amp draw to document the improvement.
Air Quality & Sanitizing in Kirby

Air quality treatment in Kirby targets the microbial and particulate load that accumulates in ductwork left untouched for 15-25 years, common in this enclave’s rental-heavy housing stock. Bexar County’s humidity spikes, combined with 140°F attic temperatures, create conditions where mold and bacteria colonize deteriorating flex duct liners and compromised mastic joints. Our Air Quality & Sanitizing service applies EPA-registered treatments with documented application records.
Mold Treatment
Signs you need it
Musty odor at startup, visible growth on register faces, or moisture staining on ceiling drywall beneath attic duct runs.
What it costs in Kirby
Whole-system mold treatment in Kirby typically runs $320-$580, including application, dwell-time documentation, and post-treatment verification photos.
How we do it
We apply an EPA-registered antimicrobial through the full duct network using controlled fogging equipment, maintain manufacturer-specified dwell time, and photograph treated surfaces for the job record.
UV Light Installation
Signs you need it
Recurrent mold after cleaning, family members with allergy symptoms that spike when the system runs, or a coil location with chronic moisture due to poor attic ventilation.
What it costs in Kirby
UV-C lamp installation in Kirby typically runs $280-$520 per lamp, including mounting, electrical connection, and annual replacement scheduling.
How we do it
We mount the lamp assembly with a sight glass for future inspection, wire to the air handler’s 24V circuit with independent switch, and record lamp intensity at installation for warranty baseline.
What Air Quality & Sanitizing Costs in Kirby
| Item | Typical range in Kirby |
|---|---|
| Mold treatment (whole system) | $320-$580 |
| UV-C lamp installation | $280-$520 |
| Bacteria sanitizing | $240-$420 |
Is mold treatment safe for my family and pets?
We use EPA-registered products with labeled dwell times, ventilate the home post-application per manufacturer protocol, and document the re-entry time on your job record. The treated surfaces are not touched during normal occupancy.
How long does UV light take to work in Kirby’s climate?
Surface mold on the coil drops measurably within 48-72 hours of continuous operation; full system effect builds over 2-3 weeks of runtime. We photograph the coil at installation and at 30 days to document the change.
Brands We Service in Kirby
We stock parts and service equipment from Aprilaire, Abatement Technologies, Guardsman, and Rotobrush, with most replacement components available for Kirby jobs without ordering delays. Our brands page lists full compatibility and manufacturer specifications.

FAQs About Air Duct Cleaning in Kirby

Kirby follows Bexar County guidelines; duct cleaning requires no permit, but duct repair or modification that alters the building envelope may need inspection. We verify permit requirements before quoting any repair work and include compliance in our scope if needed.
Tenant or owner, we require written authorization from the property owner or management company before entering any rental unit. We provide a simple authorization form and can coordinate directly with out-of-area landlords to confirm scope and pricing.
The $79 coupon model relies on upselling once inside the home; our price is the full price, agreed in writing before work starts. In Kirby’s older housing stock, the actual work required typically exceeds what a coupon visit can legally or physically cover, which is why we document every duct run with before-and-after photos as proof of completion.
