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 Duct Repair & Sealing in Elk Grove Village: What to Know First
We provide independent Guardsman duct repair and sealing in Elk Grove Village, with most repairs completed in a single visit and a written price delivered before any work starts. A typical Guardsman duct sealing job runs $380-$620 for a full system, while flex duct repair or metal duct patching ranges $240-$490 depending on accessibility and material. We’re not affiliated with Guardsman - we service their products as an independent Guardsman service provider - and we back every job with our 365-Day Done Right Promise in writing.
This page is for Elk Grove Village homeowners who found this page because their Guardsman air handler, whole-house dehumidifier, or ERV/HRV unit is connected to ductwork that leaks, whistles, or delivers uneven temperatures. If that’s your situation, call (224) 344-8881 and we’ll put a written estimate next to any competitor’s quote for free.
How Guardsman Products Fail - and How We Fix Them
- Guardsman ERV Series 150/200: cracked polymer duct collars at the unit connection. The ERV’s plastic intake/exhaust collars fatigue from Elk Grove Village’s freeze-thaw cycles - the housing expands and contracts against rigid metal duct. We cut back to sound material, transition to flexible insulated duct with a reinforced sleeve, and seal with mastic rated for the temperature swing. OEM collars are available but often back-ordered; we stock quality aftermarket transitions that mate cleanly.
- Guardsman whole-house dehumidifier: supply duct collapse at the plenum tap. The DH-series units pull hard negative pressure; if the tap into the main supply plenum was cut oversize or unsupported, the duct wall sucks inward and tears. We sister in a metal saddle, re-tap with proper gauge, and add a turning vane so the dehumidifier doesn’t fight the main blower. We’ve replaced three of these in Elk Grove Village split-levels near Biesterfield Road since 2021.
- Guardsman Series 90 media air cleaner: bypass duct seal failure. The bypass damper gasket degrades where it meets the return plenum, dumping unfiltered return air into the supply. We remove the old gasket channel, machine a new seat if the sheet metal has eroded, and reinstall with closed-cell neoprene rated for HVAC duty - not the hardware-store foam that collapses in six months.
- Guardsman flex duct in attic runs: rodent damage at the vapor barrier. Elk Grove Village’s mature tree canopy means roof rats; they nest in attic insulation and chew flex duct for nesting material. We sleeve the damaged run with new R-8 flex, seal all joints with mastic (not tape alone), and photograph the before condition so the homeowner has documentation for their insurer if the damage is extensive.
- Guardsman metal duct: seam separation at longitudinal locks, especially in 28-gauge trunk lines. The lighter gauge metal used in some Guardsman-compatible builder-grade systems flexes at the seam lock when the blower cycles on and off. We spot-weld or screw-strip the seam, coat with fiber-reinforced mastic, and test static pressure before and after to confirm the leak is sealed - not just covered.
Our Guardsman Duct Repair & Sealing Process
- 1
Visual and camera inspection. We photograph every register, duct run, and unit connection before touching anything. The customer sees what we see before we name a price.
- 2
Written scope and price. Haven Standard Clause 1: the price is written, itemized, and agreed before work starts. No exceptions. “Call for a quote” does not exist in our process.
- 3
Parts decision with the customer. If OEM Guardsman parts are available and cost-effective, we use them. If back-ordered or priced beyond reason, we present quality aftermarket equivalents with manufacturer spec sheets so the customer chooses informed.
- 4
Repair and seal. We repair or replace the damaged section, seal with mastic or foil tape per application, and insulate where the duct passes unconditioned space. Every joint is pressure-tested.
- 5
Documentation and final test. After photos of the completed work, we measure static pressure and temperature at multiple registers to verify balanced flow. The photo record and test results go to the customer as standard deliverables.
- 6
Written guarantee. The 365-Day Done Right Promise goes on paper before we leave. If the repair fails, we make it right - not subject to manager approval, backed in writing.

Why Elk Grove Village Homeowners Call CleanRun Air Duct Cleaning Elk Grove Village for Guardsman Work
We’ve worked in Elk Grove Village since 2013, including a stretch of older split-levels near Busse Woods where the flex duct had been collecting debris since the Clinton administration. Tomas Reyes and our crew know Guardsman’s product line from hands-on time, not catalog browsing - we carry common repair parts because we’ve learned what fails, and we name the brands we use (Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman equipment where applicable) so customers can verify before agreeing.
Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. Every job leaves with a Documented Photo Record of every duct run, before and after, and the 365-Day Done Right Promise in writing. We also service Lennox, Trane, and Carrier systems, which matters when your Guardsman component is integrated with another manufacturer’s air handler and the problem is at the interface.
Tomas Reyes runs this crew. His rule on every job: show the photo first. Talk second.
FAQs
No - independent repair of connected ductwork does not void a Guardsman equipment warranty, provided the work does not alter the unit’s electrical or refrigerant systems. We document our scope with photos so there’s a clear record of what was and wasn’t touched. Call (224) 344-8881 if you have warranty paperwork you’d like us to review before we start.
Most single-run repairs or sealing jobs finish in two to four hours. Full-system sealing on a larger Elk Grove Village home may take a full day. We schedule by the job, not by the hour, and the written price does not change if the work runs longer than estimated. For timing on your specific system, call (224) 344-8881.
Replace if the ductwork is galvanized steel with widespread corrosion, if asbestos wrap is present and disturbed, or if the original design cannot support your current HVAC load. Repair is usually the better value for isolated leaks, single failed joints, or flex damage in otherwise sound systems. We photograph the condition and explain both paths with prices for each - no default toward the bigger ticket. Call (224) 344-8881 for an honest assessment.
OEM collars and gaskets are preferable for exact-fit connections at the ERV or dehumidifier housing, but for standard duct repair - flex, metal, mastic, insulation - quality aftermarket parts from recognized HVAC suppliers perform identically and often ship faster. We stock both, present the option, and let the customer decide with spec sheets in hand. Call (224) 344-8881 to discuss what’s in stock for your model.
We measure static pressure and temperature at multiple registers before and after, and we deliver those numbers with the photo record. If the system had a 15-degree temperature split between rooms before sealing and 4 degrees after, you have data, not a promise. The 365-Day Done Right Promise covers any seal that fails within a year. Call (224) 344-8881 if you want to see sample documentation from a past job.
