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.

AfterGuardsman Air Duct Cleaning in Alexandria: What to Know First
We provide independent Guardsman air duct cleaning in Alexandria for residential and light commercial systems, with most jobs scheduled within a week and completed in a single visit. A typical whole-home Guardsman system runs $380-$620 in this market, and we deliver that number in writing before any panel comes off. This page is for Alexandria homeowners who own a Guardsman air handler, furnace, or packaged unit and need the ductwork cleaned without the coupon-game pricing that dominates this industry. Call (240) 318-7712 for a written estimate.
How Guardsman Products Fail - and How We Fix Them
- GMH95 and GMV95 furnace blower compartments load with fine particulate faster than comparable Lennox or Carrier units. The blower housing on these 90%-plus AFUE models sits lower to the slab in many Alexandria crawl-space installs, pulling more basement dust and pollen through the return. We remove the blower assembly, photograph the debris loading at the squirrel cage, and clean the full compartment before reassembly. A dirty blower on a GMH95 strains the ECM motor and shows up as weak register airflow upstairs in Del Ray colonials with finished third floors.
- GPG14 and GPG16 packaged units common in Alexandria’s 1950s-1970s ranch neighborhoods suffer condensate pan and evaporator coil contamination that migrates into ductwork. The horizontal discharge design on these rooftop and slab-mounted units lets standing pan water aerosolize into the supply plenum during shoulder seasons. We treat this as a duct-and-coil job, not duct-only. The photo record shows the pan before cleaning and the coated coil after treatment.
- Guardman GMS8 and GMS80 single-stage furnaces in older Alexandria homes often have original flex duct that’s degraded around the plenum connection. The temperature swing in a mid-Atlantic winter, 20°F one day and 60°F the next, hardens the rubberized collar. We flag this during pre-cleaning inspection. Replacing a cracked collar with a quality aftermarket connection costs less than OEM and performs identically; we document the swap in writing under Haven Standard Clause 1.
- Guardman communicating systems (GCVM96, GCVC8 with ComfortBridge) throw airflow fault codes when duct static pressure climbs from debris buildup. The variable-speed blower ramps to compensate, then faults out. Homeowners see ” airflow restriction” on the thermostat display. We measure static pressure before and after cleaning with a digital manometer; the photo record includes the gauge readout. If the fault persists, we know to look past the ducts.
- GME8 and GME80 electric furnace sequencers in Alexandria’s all-electric subdivisions near Eisenhower Avenue corrode from humidity pulled through leaky return ductwork. The corrosion flakes enter the airstream and distribute through the house. We seal accessible return leaks with mastic during the cleaning pass, photograph the sequencer condition if the panel is open, and note any replacement need in the written scope. This is the difference between vacuum noise and documented work.
Our Guardsman Air Duct Cleaning Process
- 1
Written price delivered on arrival. Haven Standard Clause 1: we inspect the accessible ductwork, identify the Guardsman model and serial, and hand you a flat price for the full system before any equipment leaves the van. No per-vent arithmetic, no “once we get in there” surprises.
- 2
Photo baseline of every duct run. We pull the access panel, insert the borescope, and photograph the inside of each supply and return run. You see what we see before we start. The duct doesn’t lie - we just show you what’s in it.
- 3
Negative-pressure extraction with Rotobrush contact agitation. We match the brush head to the duct diameter; Guardsman systems in Alexandria’s smaller 1940s homes often have 6-inch galvanized trunk lines that need a smaller brush than the 8-inch flex common in 2000s construction. Debris is captured at the vacuum source, not pushed downstream.
- 4
Component-specific cleaning for the Guardsman unit. Blower compartment, evaporator (if accessible), and condensate pan are cleaned and photographed. OEM Guardsman parts are used where warranty coverage is active; quality aftermarket substitutes are proposed in writing where warranty has expired.
- 5
Post-cleaning verification. Static pressure measured, register airflow checked with an anemometer, and after photos of every run delivered with the job record. The 365-Day Done Right Promise is dated and signed.
- 6
Cleanup and documentation. All panels reinstalled, work area vacuumed, and you receive the complete photo record, written scope, and warranty document before we leave.
BeforeAfterWhat Guardsman Air Duct Cleaning Costs in Alexandria
These are the whole-system ranges we quote in writing for Guardsman equipment in the Alexandria market:
- Single-zone residential, up to 12 runs: $380-$480
- Two-zone or larger home, 13-20 runs: $490-$620

- With dryer vent routing through same plenum: add $75-$125
- Commercial light-duty Guardsman package units: $680-$950, scoped on site
What moves the price: duct material (flex takes longer than rigid), accessibility (crawl space vs. basement), and whether the job requires coil or blower compartment access. We also service Lennox, Trane, and Carrier systems with the same written-price protocol.

Why Alexandria Homeowners Call CleanRun Air Duct Cleaning Alexandria for Guardsman Work
We’ve been in Alexandria since 2013, and the Guardsman product line has been a steady presence in the homes we service - particularly the GMH95 and GPG series in the post-war neighborhoods between Route 1 and the Beltway. Tomas Reyes, our owner, has handled enough of these units to know the failure patterns before pulling the first panel. Every job carries the 365-Day Done Right Promise in writing, every crew member is background-checked and uniformed under Haven Standard Clause 3, and the photo record is standard, not an upsell. When a Guardsman communicating system throws a code, we have the diagnostic tools to distinguish a duct problem from a control problem. That’s the difference between a cleaner and a technician.
FAQs
No. Routine duct cleaning does not void your Guardsman equipment warranty, provided the work is performed by a qualified technician who does not disturb sealed components. As an independent Guardsman service provider, we document every panel removal and reinstallation in the job record so warranty coverage remains intact. Call (240) 318-7712 if your unit is still under factory warranty and you’d like us to confirm coverage before scheduling.
We stock common Guardsman blower belts, capacitors, and contactors, and we source OEM parts through standard HVAC distribution when a specific component is needed. For out-of-warranty systems, we also carry quality aftermarket equivalents that meet or exceed OEM specifications; we list both options in writing with prices before any replacement. Call (240) 318-7712 to discuss parts availability for your specific model.
You receive a Documented Photo Record of every duct run, before and after, as a standard deliverable on every job. The photo record is time-stamped and included with your written scope and invoice. If the after photo doesn’t show clean metal or flex, the job isn’t done. Haven Standard Clause 2 requires this documentation on every visit.
Heavy duct contamination alone rarely justifies full system replacement. If your Guardsman furnace or air handler is under 12 years old and the heat exchanger or compressor tests sound, we clean the ducts and components and return the system to baseline performance. We recommend replacement only when the equipment has reached the end of its service life or a major component has failed; we put that assessment in writing with the photo evidence to support it. Call (240) 318-7712 for a free second opinion if another contractor has recommended replacement.
Most Alexandria homeowners with Guardsman systems benefit from duct cleaning every 5-7 years, sooner if you have completed renovation work, own pets that shed heavily, or run the fan continuously. The mid-Atlantic pollen season, March through May, loads filters and ductwork faster than desert or northern climates; we see the evidence in April and May inspections. If you’re unsure, we offer a video inspection with the borescope for a flat fee that applies toward cleaning if you proceed within 30 days. Call (240) 318-7712 to schedule.
