Fast, Reliable HVAC Cleaning Across Alexandria
Professional HVAC cleaning in Alexandria typically runs $280-$650 for a complete system service, and most jobs are finished in a single visit. We’re Bellows Air Duct & Vent Co., and we’ve been driving our trucks to Alexandria since 2012 - long enough to know the difference between a postwar ranch in the southern ZIPs and a Federal brick row house in Old Town where the ductwork was cobbled in decades after the walls went up. If you’re in 22332, 22333, 22334, or 22336, we’ll be there when we say. Call (844) 685-6342 and a live person answers, 24 hours a day.
Why Bellows Air Duct & Vent Co. Is Alexandria’s Preferred HVAC Cleaning Company
We’ve built our reputation in Alexandria on showing up, doing the work, and standing behind it. Our HVAC Cleaning team knows the local housing stock - the retrofit forced-air systems in Del Ray bungalows, the rubble-stone crawl spaces under Old Town brick, the garden apartments off Route 1 that were never designed for central air. That matters because a technician who treats every job like a suburban tract home will miss the debris pockets and mold colonies that hide in Alexandria’s convoluted duct runs.
Our customers in Alexandria call us back because we camera-inspect every system before and after we clean. You see what we see. No claim without proof. Our 90-Day Done Right Promise is stamped on every job - if it’s not right, we return at no charge, no paperwork, no arguing. That’s been our way for over 14 years.
Calls are answered by a live person, not a voicemail tree, not an app. Background-checked, uniformed technicians. Upfront pricing disclosed before a single tool is lifted. The number on the phone is the number on the invoice.
Our HVAC Cleaning Services in Alexandria
Evaporator Coil Cleaning
The evaporator coil is where your system works hardest, and in Alexandria it’s working against 80% summer humidity in neighborhoods like Eisenhower Valley and the Old Town waterfront. That moisture condenses on the coil, trapping dust and creating a film that cuts efficiency and breeds mold. We clean coils with low-pressure foaming agents and soft brushes - never the high-pressure washers that bend fins and void warranties. A typical evaporator coil cleaning in Alexandria runs $180-$320.
Blower Cleaning
The blower wheel moves every cubic foot of air through your home. When it’s caked with dust, your system runs longer, costs more, and still can’t keep up on a July afternoon in Alexandria. We remove the blower assembly, clean the wheel and housing, and re-balance before reinstall. Most blower cleanings in Alexandria homes fall between $150-$280.
Condenser Cleaning
Your outdoor condenser sits through Alexandria’s pollen seasons, summer storms off the Potomac, and the leaf drop from mature oaks in neighborhoods like Rosemont and Beverley Hills. We clean coils, straighten fins, and check refrigerant levels. A condenser cleaning alone typically costs $120-$220 in Alexandria; bundled with full system service, it’s often included at reduced rate.
Air Handler Cleaning
The air handler is the heart of retrofitted systems - and in Alexandria’s pre-1950 housing stock, it’s often crammed into a closet or kneewall space never meant to house it. We clean the cabinet, drain pan, and associated components, checking for standing water and microbial growth. Air handler cleaning in Alexandria runs $200-$380 depending on accessibility and condition.
Coil Treatment
In Alexandria’s river-humidity climate, cleaning alone sometimes isn’t enough. We apply EPA-registered coil treatments that inhibit mold regrowth without leaving residues that circulate through your home. This is particularly important in Old Town and Del Ray homes where supply ducts run through unconditioned spaces. Coil treatment adds $85-$150 to a standard cleaning.
Heat Exchanger Cleaning
For gas-fired systems, the heat exchanger must be clean and intact for safe, efficient operation. We inspect with cameras and clean as needed, documenting condition for your records. Heat exchanger service in Alexandria typically ranges $160-$290.

Trusted Brands We Service in Alexandria
We clean and maintain systems built with Aprilaire, Honeywell, Rotobrush, and Abatement Technologies components - the same brands serious HVAC contractors specify for new installations. We stock common parts for Alexandria customers, so most repairs and maintenance visits don’t stretch into a second trip. Our technicians train on current equipment lines, but they’re also experienced with the aging systems common in Alexandria’s older neighborhoods. When your 1980s retrofit air handler needs attention, we know the hardware.
Common HVAC Cleaning Problems We See in Alexandria Homes
- Hidden debris in rubble-stone crawl spaces. In Old Town’s 19th-century brick townhomes, flex duct runs horizontally through original crawl spaces with clearances under 18 inches. These sections are nearly inaccessible to standard rotary-brush equipment and become pockets of standing debris and mold that homeowners have no way to inspect themselves. Our flex-access adapters reach where standard equipment cannot.
- Aging flex duct collapsing under vacuum pressure. Postwar ranch homes in southern ZIPs like 22306 and 22310 were converted from radiator heat to forced-air in the 1970s, leaving behind flex duct and makeshift plenums now well past typical service life. We adjust our vacuum pressure and use camera guidance to avoid damage during cleaning - and we’ll show you what we find.
- Mold colonization from Potomac humidity. Alexandria’s ambient summer humidity exceeds 80% regularly, higher than inland Fairfax or Arlington. Condensation inside supply ducts during cooling season creates conditions where mold colonizes within 24-48 hours of moisture contact. Cleaning without coil treatment and proper drying often means regrowth within weeks.
- Construction dust from decades of renovations. Del Ray and Old Town homes have been renovated repeatedly since original construction. Each project leaves fiberglass, drywall dust, and sawdust in wall cavities that eventually migrates into retrofitted ductwork. We regularly extract material that has accumulated since the 1980s installation.

FAQs - HVAC Cleaning in Alexandria
Yes. We use Rotobrush flex-access adapters and camera-guided tools specifically for tight crawl spaces common in Old Town and Del Ray. Last spring, we cleaned a 1924 craftsman bungalow on Commonwealth Avenue in Del Ray where the original owner had retrofitted forced-air in the 1980s using flexible duct through a 14-inch kneewall cavity. Our equipment was the only system that could reach the debris-laden horizontal run behind the masonry chimney, extracting over 12 pounds of pet hair and construction dust. If your crawl space is too tight even for our flexible tools, we’ll show you the camera footage and discuss options - no charge for the inspection. Call (844) 685-6342 to schedule.
Very likely, yes. Flex duct installed in the 1970s-1980s has a typical service life of 25-30 years, meaning most conversions in Del Ray and Rosemont are now past due. We camera-inspect before cleaning to assess condition. If we find collapsed, torn, or disconnected sections, we’ll show you the footage and quote repair or replacement before proceeding - we don’t clean through damaged ductwork that will just recontaminate. Our $89 Seasonal Tune-Up includes a basic duct condition assessment. Call (844) 685-6342.
Cleaning removes existing mold and debris, but in Alexandria’s 80%+ summer humidity, cleaning alone often isn’t sufficient. We recommend pairing duct cleaning with evaporator coil cleaning and EPA-registered coil treatment to inhibit regrowth. The root problem is condensation in supply ducts during cooling season, which requires addressing both the biological growth and the moisture conditions that create it. A complete mold-focused service in Old Town typically runs $450-$720. Call (844) 685-6342 for a free inspection and exact quote.
Yes. Garden apartments in ZIPs like 22306 and 22310 typically have purpose-built duct systems with better access and standardized dimensions, so we can use more aggressive vacuum pressure and larger-diameter brushes. The equipment is different, the time required is usually less, and pricing often falls in the lower half of our ranges. We still camera-inspect before and after - that’s non-negotiable on every job - but the process moves faster than in a retrofitted Del Ray bungalow. Call (844) 685-6342 for an estimate.
Yes. We clean, maintain, and repair Aprilaire and Honeywell media filters, electronic air cleaners, and whole-home filtration systems installed in Alexandria homes. These components require regular cleaning to maintain airflow and efficiency, particularly in older homes with higher baseline dust loads. Filter maintenance is typically included in our complete system service or can be scheduled separately. Call (844) 685-6342 to discuss your specific system.
