Air Duct Cleaning Company in Castle Hills, TX

Air duct cleaning in Castle Hills runs $450 – $750 for a typical 2,000 – 2,600 sq ft home with a single HVAC system. Most jobs take 3 – 5 hours. The difference in Castle Hills comes down to the housing stock: homes built between the 1960s and 1980s with flex duct run through unconditioned attics that bake in the South Texas sun, which means dust, pollen, and sometimes mold end up where they shouldn’t. Call (254) 347-3897 for a written quote before any work starts.

Why Castle Hills Homes Are Different

Castle Hills homes present a specific set of duct conditions you won’t find a few miles south in newer developments. Many houses date to the 1960s through the 1980s and still run original or early-generation HVAC systems with flex duct snaking through attics that regularly hit 130°F in July. That heat degrades duct insulation over time, and the temperature swings create condensation inside the ductwork when the AC cycles on. Condensation plus organic dust from Castle Hills’ towering live oaks equals a prime environment for mold growth inside the system.

The live oaks are the other factor locals know well. Older Castle Hills neighborhoods are shaded by mature trees that shed enormous amounts of pollen and leaf litter each spring and fall. Much of that fine debris gets pulled through return ducts and settles inside supply runs. Homes with pier-and-beam foundations face an additional challenge: crawlspace air, which carries dust and humidity, often finds its way into return plenums through small gaps and seams. A duct cleaning in Castle Hills is rarely just about dust. It’s about heat stress, humidity, and a tree canopy that keeps the returns full.

Our Main Castle Hills Services

We offer three services across Castle Hills, each with its own dedicated page covering local conditions, pricing, and what the job involves.

Dryer Vent Cleaning in Castle Hills

Dryer vents in Castle Hills clog faster than homeowners expect, partly because lint traps can’t catch everything and partly because vent runs through hot attics bake the lint into a dense, stubborn layer. Homes with laundry rooms on interior walls often have longer vent runs with one or two elbows, which catch more debris. We clean the full run from dryer to exterior termination and verify airflow at the exit point. Omar Haddad oversees every Castle Hills job to make sure the work meets our standard. See the full breakdown on our Dryer Vent Cleaning in Castle Hills page.

Air Duct Cleaning in Castle Hills

Air duct cleaning in Castle Hills means addressing what the local climate puts into the ducts: oak pollen, attic heat stress, and humidity-driven contamination. We use a Rotobrush rotary brush system to agitate debris off duct walls paired with a Nikro HEPA vacuum running negative-pressure extraction, which means loosened debris goes straight into the vacuum rather than back into your living room. Castle Hills homes with original flex duct often benefit from a full cleaning before the first big pollen season hits. Full details on our Air Duct Cleaning in Castle Hills page.

HVAC Cleaning in Castle Hills

HVAC cleaning covers the entire air-handling system: evaporator coil, blower motor, housing, drain pan, and the supply and return plenums. In Castle Hills, where AC systems run nearly year-round, the coil and blower pick up a film of dust and pollen that cuts airflow and drives up cooling bills. We clean the components without removing ductwork, and every repair we make carries a written guarantee. Castle Hills homeowners can see exactly what’s involved on our HVAC Cleaning in Castle Hills page.
