Call (866) 347-2063 for a free estimate with upfront pricing before we lift a single tool.
We’ve been driving out to Granbury from our Houston headquarters for more than 42 years, and we know the difference between a courthouse-square Victorian with original plaster walls and a 2019 build off Highway 377 near the lake. That matters because the air quality problems in those two homes have almost nothing in common. Our Air Quality & Sanitizing team treats the house we find, not the one we expected.
Why Bellows Air Duct & Vent Co. of Texas Is Granbury’s Preferred Air Quality & Sanitizing Company
Granbury homeowners don’t call us because of a coupon. They call because their neighbor in Pecan Plantation told them we actually showed up when we said we would, ran a camera through the ducts before and after, and handed them a price on paper that matched the price on the invoice. Our 90-Day Done Right Promise is stamped on every job in writing. If it’s not right, we make it right. No paperwork, no arguing.
We answer the phone with a live person, 24 hours a day. Not a voicemail tree, not an app. When cedar season hits in December and your allergies spike at 10 PM, someone who can dispatch a technician picks up. Our technicians are background-checked, uniformed, and trained on Rotobrush and Nikro equipment. They know that homes off Fall Creek Highway face different humidity loads than homes in the Brookshire Hills area, and they adjust their approach accordingly.
Our reputation in Hood County is built on one thing: never needing to be called back. That’s the square deal we promised when Wade Kellerman founded Bellows in 1984, and it’s the same promise we drive out with on US-377 today.
Our Air Quality & Sanitizing Services in Granbury
Mold Treatment
Granbury’s position directly on Lake Granbury reservoir elevates indoor humidity well above surrounding Hood County scrubland. In lakefront and cove-side homes, particularly slab-on-grade construction with limited vapor control, that moisture saturates duct insulation and seeds mold colonies near floor registers. We treat active mold with EPA-registered solutions, then camera-verify the elimination before we leave. A typical mold treatment in Granbury runs $450-$650 depending on linear footage of affected ductwork.

Bacteria Sanitizing
HVAC systems in Granbury run nearly continuously from May through September under sustained 95-105°F heat. That constant airflow accelerates the accumulation of organic debris where bacteria colonize. We apply professional-grade sanitizing agents through the full duct system, not just at the vents, and we verify coverage with camera inspection. Bacteria sanitizing in Granbury typically costs $275-$425 for a standard residential system.

Odor Removal
Musty odors in Granbury homes often trace back to the same source: seasonal vacancy in cove-side properties where mold establishes in warm, moist ducts when the AC cycles infrequently, then releases spores and volatile compounds upon restart. We don’t mask odors. We source them with camera inspection, eliminate the biological cause, and verify the result. Most odor removal jobs in Granbury fall between $325 and $500.

UV Light Installation
UV light systems neutralize mold spores, bacteria, and viruses at the coil and air handler, preventing colonization before it starts. For Granbury homes battling both lake humidity and mountain cedar pollen, a UV light is often the most cost-effective long-term control. We install Honeywell UV systems starting at $380-$550, including mounting and electrical connection. In Pecan Plantation, we recently sanitized an original 1970s fiberglass duct board system where delamination at flex connections had trapped decades of cedar pollen and lake-air particulates. After installing a Honeywell UV light and an Aprilaire air purifier, the homeowners reported a dramatic reduction in allergy symptoms during peak cedar season.

Air Purifier Installation
Whole-home air purifiers from Aprilaire integrate with your existing HVAC to capture particles down to 0.3 microns. In Granbury, where December-through-February mountain cedar pollen creates some of the heaviest allergen loads in Texas, a whole-home purifier reduces the burden on your ducts and your lungs. Installation typically runs $480-$720 depending on system compatibility and existing duct configuration.

Allergen Reduction
The Ashe juniper pollen that hammers Granbury from December through February deposits in duct systems at volumes a Tarrant County home simply doesn’t experience. We combine mechanical agitation, HEPA vacuum extraction, and targeted sanitizing to remove accumulated pollen, dust mite debris, and pet dander. Allergen reduction service in Granbury typically costs $300-$450 for a complete residential system.

Common Air Quality & Sanitizing Problems We See in Granbury Homes
- Lakefront slab homes with failed vapor barriers. Homes on Water’s Edge Drive and similar lakefront streets often lack proper ground vapor control. Humidity rises through the slab, saturates flex duct insulation, and creates mold colonies at floor registers that homeowners mistake for simple dust.
- Pecan Plantation’s original fiberglass duct board collapse. Technicians routinely find 1970s-80s fiberglass duct board that has delaminated and collapsed inward at flex connections, choking airflow and trapping decades of cedar pollen and lake-air particulates in pockets the HVAC filter never reaches. A walk-through inspection there almost always reveals it.
- Seasonal vacancy mold blooms in cove-side properties. When homeowners close up their lake house for fall and winter, residual humidity in the ductwork allows mold to establish in the warm, dark interior. The first heating cycle in spring releases a visible puff of spores. We see this pattern every March in the 76049 ZIP code.
- Mountain cedar infiltration through compromised return plenums. The sheer volume of December-February Ashe juniper pollen overwhelms standard filtration in older Granbury homes where return plenums have separated from the air handler, drawing unfiltered attic or crawl space air directly into the system.

FAQs - Air Quality & Sanitizing in Granbury
The reservoir elevates indoor relative humidity 15-25% above Hood County scrubland levels, particularly in slab-on-grade lakefront homes with limited vapor barriers. That moisture condenses inside cool ductwork and creates the warm, wet environment where mold colonies establish between seasonal uses. If you own a lakefront or cove-side property in the 76048 or 76049 ZIP code, we recommend annual inspection and more frequent sanitizing than inland Granbury homes. Call (866) 347-2063 for a free assessment.
Pecan Plantation was built from the mid-1970s onward with original fiberglass duct board and early flex-duct connections that are now 40-50 years old. The material delaminates and collapses inward at flex junctions, a failure mode we rarely see in 1990s or newer construction. That collapse traps debris in permanent contamination pockets the HVAC filter cannot reach. If your Pecan Plantation home has never had professional duct inspection, we almost always find this condition. Call (866) 347-2063 for a camera inspection.
A properly sized Honeywell UV light system at the coil and air handler neutralizes mold spores and bacteria that pollen debris feeds, but it does not filter pollen itself. For Granbury’s extreme cedar season, we typically pair UV installation with an Aprilaire whole-home air purifier that captures particulates down to 0.3 microns. The combination runs $780-$1,150 installed and addresses both the biological growth and the pollen load. Call (866) 347-2063 for sizing recommendations specific to your system.
Lakefront homes that sit vacant for more than three weeks at a stretch should be inspected and sanitized before each extended occupancy period, typically spring and fall. The seasonal vacancy pattern in cove-side Granbury properties allows mold to establish in warm, moist ducts when AC cycles infrequently, then release spores upon restart. For year-round lakefront residents, annual sanitizing with mid-summer filter changes is the standard we recommend. Call (866) 347-2063 to set up a schedule.
A musty or earthy odor when the HVAC first cycles on, especially after the system has been off for several hours or days. In Granbury, this often appears in spring when homeowners reopen lake houses, or in fall when the first heating cycle disturbs colonies that grew through the humid summer. Visible mold at floor registers is usually a late-stage indicator. If you smell it, it’s already established. Call (866) 347-2063 for a free camera inspection and upfront quote.
