Bellows Air Duct & Vent Co. has served the Park Cities area for over 42 years, and our HVAC Cleaning team knows the specific challenges of Highland Park’s historic estate homes. We answer calls live, 24 hours a day, at (844) 685-6342, and we arrive when we say we will.

Why Bellows Air Duct & Vent Co. Is Highland Park’s Preferred HVAC Cleaning Company
We’ve been driving to Highland Park since 1984, long before the teardown-and-rebuild cycle turned every other lot into a construction zone. Our technicians are background-checked and uniformed, and they carry camera inspection equipment on every truck. That matters here. A standard cleaning outfit from Dallas might vacuum the main trunk and call it done. We photograph before and after every job, and our 90-Day Done Right Promise means if something’s not right, we return at no charge with no paperwork to argue over.
Ray Castillo built this company on the idea that a homeowner should know the price before a single tool is lifted. That hasn’t changed. Our office answers calls live around the clock, not voicemail, not an app. Highland Park residents who’ve lived in the same house for twenty or thirty years tell us they call us because we pick up the phone and we show up. The number we quote is the number on the invoice.
Our HVAC Cleaning Services in Highland Park
Evaporator Coil Cleaning
Highland Park’s oversized multi-zone systems run almost continuously from June through September, when Dallas-area temperatures routinely exceed 100°F. That constant cycling packs debris onto evaporator coils faster than in homes with newer, right-sized equipment. We clean coils with pressurized foam and rinse, then verify airflow improvement with before-and-after camera documentation. A typical evaporator coil cleaning in Highland Park runs $180-$320.

Blower Cleaning
The blower assembly in a Highland Park home’s air handler works harder than designed because retrofitted ductwork creates higher static pressure. Dust and construction particulates accumulate on blower fins, reducing airflow and forcing the motor to draw more current. We remove and clean the blower assembly, balance the fan, and check amp draw. Most blower cleanings in Highland Park fall between $150-$280.

Condenser Cleaning
Highland Park’s mature post oaks and American elms shed significant organic material each spring and fall. That debris clogs condenser fins and traps heat, raising head pressure and utility bills. We clean condenser coils with foaming cleaner and fin combs, then clear the concrete pad and surrounding area. Condenser cleaning in Highland Park typically costs $120-$220.

Air Handler Cleaning
Many Highland Park air handlers sit in tight attic chases or retrofitted closets not designed for modern equipment. Limited access means partial cleaning is common from less experienced crews. We disassemble what the space allows, clean all reachable surfaces, and photograph what we can’t reach for the homeowner’s records. Air handler cleaning runs $200-$380 depending on access and system size.

Heat Exchanger Cleaning
Older Highland Park homes with original furnaces or mid-century replacements need careful heat exchanger inspection and cleaning. Cracked or corroded exchangers are a genuine safety hazard, releasing combustion gases into living spaces. We inspect with cameras and mirrors, clean accessible surfaces, and document condition. If replacement is needed, we explain exactly why. Heat exchanger cleaning and inspection in Highland Park runs $160-$290.

Coil Treatment
After cleaning, we apply antimicrobial coil treatments using products from Abatement Technologies to slow biological regrowth. Highland Park’s humidity, combined with construction dust that traps moisture, creates conditions where mold recurs quickly without treatment. This add-on service runs $80-$150 and is included in our comprehensive cleaning packages.

Trusted Brands We Service in Highland Park
We clean and maintain systems built with Aprilaire media cleaners, Rotobrush duct cleaning equipment, Abatement Technologies HEPA filtration, and Honeywell controls. Our trucks stock common replacement parts for these brands, which means faster turnaround for Highland Park homeowners and fewer return visits. When a coil treatment or filter change requires a specific Aprilaire or Honeywell component, we typically have it on hand. For specialty items, our Dallas-area supplier delivers same-day.
Common HVAC Cleaning Problems We See in Highland Park Homes
- Hidden dead-end ducts trap contamination for years. Luxury kitchen and addition renovations frequently cap off original branch runs behind new cabinetry or finished walls. Standard cleaning never touches these segments, which continue releasing mold spores and debris into the system. We locate and clean them when accessible, or document their presence for the homeowner.
- Retrofitted flex duct splices damage easily. Many Highland Park homes contain 1940s-era flex duct spliced into newer branch runs. High-velocity agitation from generic vacuum equipment can tear these aged connections, creating leaks that waste conditioned air. Our Rotobrush systems use controlled, lower-velocity contact cleaning that removes debris without stressing fragile splices.
- Construction dust re-contaminates systems within months. The constant teardown-and-rebuild cycle on adjacent Highland Park lots pumps fine particulates into the air year-round. Without HEPA-grade containment like our Abatement Technologies equipment, post-cleaning dust re-settles onto coils and blower surfaces within days. We seal registers and maintain negative pressure during cleaning to prevent this.
- Oak and elm pollen loads overwhelm standard filtration. Highland Park’s canopy of mature post oaks and American elms produces pollen counts that exceed newer, tree-sparse suburbs. That biological load enters outdoor air intakes and accumulates on evaporator coils, accelerating the cycle of contamination and reduced efficiency.

FAQs - HVAC Cleaning in Highland Park
Highland Park’s combination of retrofitted duct infrastructure and constant adjacent construction creates a uniquely aggressive debris load. The teardown-and-rebuild cycle on neighboring lots pumps fine construction dust into the air year-round, and that dust infiltrates duct systems through every seam and access point. University Park shares some historic housing stock but sees less concentrated construction activity, so contamination recurrence is slower. Call (844) 685-6342 for a free estimate on your system’s condition.
We locate and clean capped dead-end segments when they’re accessible, and we document them when they’re not. We serviced a 1930s estate on Armstrong Avenue where the owner noticed worsening allergy symptoms after a kitchen renovation. Using our Rotobrush system, we found a capped dead-end duct segment, spliced during a past luxury remodel, that had been trapping mold spores and construction dust behind new cabinetry for years. After cleaning the hidden trunk line and applying a coil treatment, the system’s airflow normalized and the owner reported immediate relief. If we can’t access a hidden segment, we’ll show you the camera footage and explain your options. Call (844) 685-6342.
Yes. Our equipment accesses ducts through existing registers and service openings, never through finished plaster. The Rotobrush system we use makes contact with duct interiors without requiring wall penetration. For Highland Park homes with original plaster walls, this matters. We seal work areas with protective coverings and maintain negative pressure to prevent dust migration into living spaces. Call (844) 685-6342 to schedule.
Yes. We apply antimicrobial coil treatments after cleaning, using products from Abatement Technologies, specifically to slow biological regrowth in Highland Park’s humid summer conditions. The treatment costs $80-$150 and is included in our comprehensive packages. It won’t eliminate mold forever, but it extends clean intervals significantly compared to untreated coils. Call (844) 685-6342 for pricing on your system.
We inspect with cameras first, identify material types and connection points, then select cleaning methods that won’t damage aged components. High-velocity agitation can tear 1940s flex splices or separate sheet-metal joints that have corroded over decades. Our technicians adjust brush speed and vacuum pressure based on what the camera reveals. We document condition throughout and show you the footage. If we find damage that predates our work, we point it out before proceeding. Call (844) 685-6342 for an inspection.
