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.

AfterAprilaire Duct Repair & Sealing in Chandler: What to Know First
CleanRun provides independent Aprilaire duct repair and sealing in Chandler with written prices delivered before any work starts and a documented photo record of every duct run. Most Aprilaire jobs we handle, from flex duct repair behind an Aprilaire 8140 ventilator to full mastic sealing on a system with an Aprilaire 1820 dehumidifier, are completed in a single scheduled visit. We do not quote per-vent teaser rates; we quote one flat price per system, agreed in writing, with no invoice surprises once the truck is on your driveway. If you own an Aprilaire whole-home ventilator, dehumidifier, or air cleaner and have noticed uneven airflow, temperature swings between rooms, or rising utility bills in your Chandler home, this page explains what we typically find and what we charge to fix it. Call (520) 464-6297 for a free estimate.
How Aprilaire Products Fail - and How We Fix Them
- Aprilaire 8140/8145 Whole-Home Ventilators: The fresh-air intake duct on these units is often flex duct run through a hot Chandler attic, and after 8-12 years the inner liner cracks where it bends over trusses. We replace the damaged flex section with insulated flex rated for 180°F attic exposure, then seal the collar connection with mastic, not tape, because tape releases in sustained 140°F+ attic heat.
- Aprilaire 1820/1830 Dehumidifiers: The return plenum (the large duct that feeds air into the unit) develops negative-pressure leaks at the seams where the dehumidifier’s blower pulls harder than the main HVAC fan. Homeowners notice the unit runs constantly but humidity barely drops. We pressure-test the plenum, seal seams with fiber-reinforced mastic, and verify the static pressure reading stays within Aprilaire’s 0.3-0.7 in. w.c. spec.
- Aprilaire 5000/5010 Electronic Air Cleaners: The power head and cell housing are mounted in the main return duct, and the weight of the assembly eventually separates the duct seams upstream. We see this most in 2015-2019 Chandler builds with thinner 26-gauge return ducts. Our repair adds a support bracket to the power head and reseals the upstream seams with mastic and mesh.
- Aprilaire 600/600M Humidifiers: The bypass duct, a 6-inch round takeoff from the supply plenum, is a common leak point because the sheet metal starter collar was never fully sealed at installation. In Chandler’s dry winters, homeowners run these units hard, and the unsealed collar bleeds heated air into the attic or wall cavity. We remove the old collar, install a sealed takeoff with a damper, and verify airflow at the humidifier pad.
- Aprilaire Zoned System Dampers: In homes with Aprilaire zoning panels, we find the flex duct connections to the motorized dampers have pulled loose where the wire tie cut into the flex liner. The damper still moves, but air leaks past the closed blade into the unused zone. We replace the damaged flex, use padded supports instead of wire ties, and test each zone’s airflow with a manometer.
Our Aprilaire Duct Repair & Sealing Process
- 1
System identification and scope: We record your Aprilaire model numbers, serial numbers, and install date, then photograph the full duct layout from the air handler to the registers. The photo tells you what the duct looked like. The invoice tells you what we did. Everything else is just conversation.
- 2
Written price delivery: Before any panel comes off, we deliver a written price under Haven Standard Clause 1. The price covers the full system, not per-vent or per-foot add-ons.
- 3
Diagnostics with documentation: We inspect every duct run with a camera, noting cracks, separations, and insulation degradation. We pressure-test the system to quantify leakage in CFM25 (cubic feet per minute at 25 Pascals of pressure).
- 4
Parts decision: For Aprilaire-specific components like collars, dampers, or plenum adapters, we use OEM parts when available. For standard duct materials, we use quality aftermarket products from Abatement Technologies and Guardsman that meet or exceed the original specifications.
- 5
Repair and seal: We repair or replace damaged duct sections, seal all seams with mastic and fiber mesh, and reinsulate where attic heat has degraded the wrap. Every connection is photographed before and after.
- 6
Verification and record delivery: We retest static pressure and airflow, deliver your documented photo record, and activate the 365-Day Done Right Promise in writing.

AfterWhat Aprilaire Duct Repair & Sealing Costs in Chandler
| Service | Typical Range | What Affects Price |
|---|---|---|
| Flex duct repair (single run, Aprilaire ventilator or zone damper) | $280 - $420 | Attic accessibility, length of damaged section, insulation replacement needed |
| Return plenum reseal (Aprilaire dehumidifier or air cleaner) | $340 - $580 | Plenum size, number of seams, support bracket addition |
| Full system mastic sealing (Aprilaire-equipped HVAC, up to 10 duct runs) | $680 - $1,150 | System tonnage, attic vs. crawlspace routing, accessibility |
| Bypass duct repair/replacement (Aprilaire humidifier) | $220 - $380 | Collar replacement, damper condition, surrounding ductwork integrity |
Prices move up when we find multiple failure points that were not visible during the initial camera inspection, or when the ductwork is routed through a tight Chandler attic with limited access. Prices stay flat when the damage is isolated to one or two runs. We do not charge per-vent fees, and we do not add trip charges or equipment fees after the written price is delivered. Call (520) 464-6297 for a free estimate - we will put our number next to any competitor’s written quote under our Free Second Opinion policy.
Why Chandler Homeowners Call CleanRun Air Duct Cleaning Chandler for Aprilaire Work
We have worked on Aprilaire equipment in Chandler since 2013, from the early 500-series humidifiers in Fulton Ranch builds to the 1800-series dehumidifiers installed alongside high-SEER systems in newer San Tan Village corridor homes. Tomas Reyes, our owner, trained in HVAC systems at Apex Technical School in Manhattan and spent two decades inside ductwork before building this crew. We also service Lennox, Trane, and Carrier systems, which matters because most Aprilaire units are integrated into mixed-brand HVAC setups where the duct failure is not brand-specific but the repair approach is.
Every technician is background-checked and uniformed under Haven Standard Clause 3: Verified Crews. You will know the technician’s name before arrival. Every job ends with a documented photo record and a written 365-Day Done Right Promise. We have served over 52,000 homes, every one with a written price before work started and a photo record when we left.
FAQs
No. Aprilaire’s warranty covers defects in their equipment, not the ductwork surrounding it. As an independent Aprilaire service provider, we use OEM parts for Aprilaire-specific components and document our work so any future warranty claim on the unit itself is not complicated by our repair. If you are concerned about a specific model, we will review the warranty terms with you before starting work. Call (520) 464-6297 and we will check your serial number against Aprilaire’s current coverage.
The unit is likely failing if it powers on but does not move air or dehumidify, or if it throws an error code. The ductwork is likely the problem if the unit runs continuously but performance is uneven, rooms have temperature swings, or your utility bills have risen without thermostat changes. We diagnose this with a camera inspection and pressure test, both included in our free estimate. Call (520) 464-6297 to schedule.
We stock common Aprilaire duct adapters, collars, and damper components for the 600, 8140, 1820, and 5000 series. Less common parts for older 400-series humidifiers or specialized zoning components typically arrive within two business days from Phoenix-area distributors. We will tell you before you agree to the written price if a part order will delay completion.
Replace the Aprilaire unit if it is over 12 years old, has repeated electrical failures, or the repair cost exceeds 60% of a new unit installed. Repair the ductwork if the unit is under 10 years old, functions properly when the ducts are sealed, or the failure is isolated to one or two runs. We will give you both numbers in writing so you can decide. Call (520) 464-6297 for the estimate.
Most single-run repairs or plenum reseals are completed in 2-4 hours. Full-system mastic sealing on a larger home takes a full day. We schedule specific arrival windows, not all-day waits, and we call 30 minutes before arrival under Haven Standard Clause 2: Respected Time. Call (520) 464-6297 to book a slot.
