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.

Why Leon Valley Homes Are Different
Leon Valley is a fully built-out postwar enclave completely surrounded by San Antonio, with nearly all residential development occurring between the 1950s and 1970s. That means a large share of homes still run original or early-generation ductwork through brutally hot attic spaces. The city sits on San Antonio’s northwest edge as one of the closest neighborhoods to the Hill Country cedar brakes, putting its aging duct systems in the direct path of Ashe juniper pollen during December-February Cedar Fever season.
The dominant housing stock is 1950s-1970s ranch-style tract homes, many still running original galvanized sheet-metal or early fiberglass duct board systems that are now 50-70 years old. These aging ducts in uninsulated or under-insulated attics, where summer temperatures routinely exceed 150°F, suffer accelerated liner breakdown, joint separation, and heavy biological buildup. Technicians working Leon Valley’s older Bandera Road-area neighborhoods frequently pull duct panels to find fiberglass duct board that has completely delaminated from decades of attic heat cycling, a failure mode common in this specific generation of construction that is often invisible from the register but dramatically restricts airflow and sheds fibers into living spaces.
The same northwest winds that carry cedar pollen also deposit fine limestone-derived dust from undeveloped Bexar County terrain that packs into supply plenums, the main distribution box that feeds each duct run. Leon Valley’s position at the northwestern fringe of the metro means its HVAC systems filter heavier concentrations of both pollen and mineral dust than neighborhoods further east or south.
Our Main Leon Valley Services
Most Leon Valley homeowners who call us need one of these three services. Each has its own dedicated page with full pricing and scope details.
Air Duct Cleaning in Leon Valley
We clean the full duct system, from return plenum to supply registers, using negative-pressure extraction, which pulls debris out while containing it so nothing settles back into your living space. In Leon Valley’s original ranch homes, we regularly find fiberglass duct board that has begun to delaminate after decades of attic heat cycling, a condition that standard cleaning cannot fix but that our photo documentation identifies before any work starts.

Dryer Vent Cleaning in Leon Valley
Dryer vent blockages are common in Leon Valley’s older homes where original vent routing runs through long horizontal attic paths or multiple elbows to reach exterior walls. We clean the full vent path from dryer connection to termination hood, measuring airflow before and after to verify restoration. Dryer Vent Cleaning in Leon Valley

AfterHVAC Cleaning in Leon Valley

HVAC cleaning in Leon Valley addresses the components that move and condition air, not just the ducts that distribute it. In homes built during the 1950s-1970s, evaporator coils and blower assemblies accumulate decades of limestone dust and cedar pollen that standard filter changes never reach, reducing capacity and forcing longer run times during Bexar County’s 100°F summer stretches. Our HVAC Cleaning service documents every component with before-and-after photos under Haven Standard Clause 1: Written Price Before Work Starts.
Evaporator Coil Cleaning
Signs you need it
Ice formation on refrigerant lines, weak airflow from registers, or cooling that cannot keep up after noon in July.
What it costs in Leon Valley
Evaporator coil cleaning in Leon Valley typically ranges from $280 to $450, with access difficulty in tight attic spaces determining where a specific job falls.
How we do it
We remove the coil cabinet cover, apply foaming cleaner formulated for aluminum fins, rinse with low-pressure water to avoid fin damage, and photograph the coil surface before reassembly.
Blower Cleaning
Signs you need it
Dust puffing from registers at startup, noisy blower operation, or uneven heating and cooling across rooms.
What it costs in Leon Valley
Blower motor and wheel cleaning in Leon Valley runs $180 to $320, depending on whether the assembly requires full removal for access.
How we do it
We disconnect power, remove the blower assembly, clean the wheel blades and housing with compressed air and solvent, balance the wheel, and reinstall with torque-verified fasteners.
What HVAC Cleaning Costs in Leon Valley
| Item | Typical range in Leon Valley |
|---|---|
| Evaporator coil cleaning | $280 - $450 |
| Blower cleaning | $180 - $320 |
| Full HVAC system cleaning (coil + blower + air handler) | $380 - $620 |
How do I know my HVAC components actually need cleaning?
We photograph the coil, blower, and plenum during our initial inspection; if the camera shows clean aluminum and minimal dust accumulation, we tell you the service is not needed. No charge for the inspection, and no work starts without a written price you approve first.
Can HVAC cleaning fix my high summer electric bills?
Restricted coils and dirty blowers force longer run times, so restored airflow often reduces cooling costs 10-20% in Leon Valley’s heat-stressed systems, though we do not promise specific savings without inspecting your equipment first.
Air Quality & Sanitizing in Leon Valley

Air quality and sanitizing in Leon Valley targets the biological load that accumulates in 50-70 year old duct systems exposed to cedar pollen, attic heat, and limestone dust. Our Air Quality & Sanitizing service treats active mold or bacterial growth and installs permanent filtration for homes where occupants experience seasonal respiratory symptoms tied to the December-February Cedar Fever peak.
Mold Treatment
Signs you need it
Musty odor at register startup, visible dark staining on fiberglass duct board, or respiratory symptoms that worsen when the system runs.
What it costs in Leon Valley
Mold treatment in Leon Valley ranges from $450 to $850 for a full system, with severity and duct material type determining final scope.
How we do it
We apply EPA-registered antimicrobial through the full duct network using mechanical fogging equipment, then verify treatment coverage with surface sampling and include results in your photo record.
UV Light Installation
Signs you need it
Repeated mold recurrence after treatment, or a household member with compromised immunity who needs continuous biological suppression at the coil.
What it costs in Leon Valley
UV-C lamp installation at the evaporator coil in Leon Valley runs $380 to $650 including the lamp assembly and electrical connection.
How we do it
We mount a UV-C lamp in the supply plenum targeting the coil surface, wire to the air handler’s 24V circuit, and verify operation with a UV meter before closing the panel.
What Air Quality & Sanitizing Costs in Leon Valley
| Item | Typical range in Leon Valley |
|---|---|
| Mold treatment (full system) | $450 - $850 |
| UV light installation | $380 - $650 |
| Bacteria sanitizing with mechanical fogging | $280 - $520 |
Will UV lights eliminate all my allergy symptoms?
UV-C lamps suppress biological growth at the coil and nearby surfaces but do not filter pollen or dust already circulating; we recommend pairing UV with proper filtration for Leon Valley’s cedar pollen load.
How do I know mold treatment actually worked?
We include pre- and post-treatment photos of affected duct sections in your standard job record, and we can arrange third-party surface sampling at your request, though most Leon Valley homeowners find the visual documentation sufficient.
