Phoenix Duct Cleaners provides Aeroseal duct sealing for homes and commercial buildings in Phoenix, Arizona. Our related services include air duct cleaning, HVAC duct cleaning, sanitizing and deodorizing, dryer vent cleaning, vent cleaning, and air duct repair. We work with single-family duct systems in Ahwatukee and Arcadia, downtown office ductwork, and warehouse HVAC runs near Sky Harbor.
Phoenix attic temperatures can rise above 150 degrees Fahrenheit, so gaps in ductwork can release conditioned air into unconditioned space before it reaches a supply register. Leaky returns can also pull hot, dusty attic air into the system and contribute to uneven temperatures. We use duct blaster testing and pressure diagnostics to measure leakage before and after treatment. Aeroseal reaches connections hidden behind walls, above ceilings, and beneath attic insulation without opening those finished surfaces.
The patented aerosol process uses a non-toxic, food-safe adhesive compound that bonds where air escapes and can seal gaps up to five-eighths of an inch. Trained technicians monitor leakage reduction in real time and provide before-and-after test data. Call to schedule a duct leakage assessment for your home or building.
Phoenix Duct Cleaners provides Aeroseal duct sealing in Phoenix, Scottsdale, Tempe, Mesa, Chandler, and the greater Maricopa County metro area.
Aeroseal is an aerosolized sealant injected into isolated ductwork under controlled pressure. Its particles remain suspended in the air stream until they reach an opening, where they collect and bond layer by layer.
Because the sealant follows the same path as moving air, it can reach plenum boxes, boot connections, takeoffs, and other joints that are buried in walls or attic insulation. That interior approach avoids tearing into drywall or removing insulation simply to reach a hidden seam.
A baseline duct blaster test establishes the starting leakage rate in cubic feet per minute. The equipment then tracks leakage reduction on a computer display, followed by a final pressure test and a printed before-and-after report.
Sealing hidden leaks can reduce wasted airflow, improve room-to-room comfort, and lower the amount of dusty attic air pulled into return ducts. The measured process also shows how much leakage changed instead of relying on a visual guess.
A successful sealing plan starts with finding leaks, correcting damaged ductwork, and preparing the system for treatment. Phoenix Duct Cleaners combines Aeroseal application with testing, cleaning, sanitizing, and repair services for residential and commercial duct systems.
The aerosolized sealant travels through pressurized ductwork and bonds only at escaping-air points. This treats hard-to-reach gaps at takeoffs, plenums, and boots while the computer display tracks progress in real time.

Residential testing can identify leakage behind uneven cooling, weak airflow in back rooms, and dusty returns. The process is suited to single-family homes, including systems with duct runs buried under blown-in attic insulation.
Request Estimate
Retail centers, office towers, apartment complexes, and warehouses may move 10,000 to 40,000 CFM or more through systems with dozens of branch connections. Work can include retail space along Camelback Road and long warehouse runs near the Loop 202 corridor, with sealing scheduled after hours or during low-occupancy windows to limit disruption.
Request Estimate
Thermal imaging reveals temperature differences around duct joints, while a duct blaster measures total leakage in CFM at a standardized pressure. Together with photographs and a physical inspection, those findings replace guesswork with documented conditions.
Request Estimate
Cleaning and sanitizing before sealing removes dust, insulation debris, and other material that could otherwise remain inside the system. Clean metal or liner also gives the aerosol a prepared surface for bonding, with deodorizing available as part of the broader duct service.
Request Estimate
Disconnected flex duct, crushed sections, torn insulation jackets, and other physical damage require repair before aerosol sealing proceeds. The inspection separates sealable leakage from conditions that call for manual repair or partial duct replacement.
Request EstimateThe right approach depends on where the leakage is located, whether the ductwork is physically damaged, how many systems serve the property, and when the space can be taken out of service. Testing and inspection guide the choice between interior aerosol sealing, manual work, repair, or a combined plan.
Interior aerosol sealing is designed for leakage distributed across installed ductwork, especially at connections that cannot be reached by hand. The controlled process isolates the system and uses its air path to locate openings.
Manual sealing uses mastic and metal foil tape at joints a technician can physically reach. It may suit accessible seams or accompany repairs, but it cannot cover connections concealed inside walls, above ceilings, or beneath insulation.
Home duct sealing addresses leakage across one or several air-conditioning systems. A typical single-family treatment takes roughly half a day to a full day, including baseline testing, injection, and final documentation.
Commercial planning accounts for large trunk lines, many takeoffs, zoned HVAC equipment, and occupancy needs. A mid-size commercial system may be completed within one service window, with a brief odor that typically clears within hours.
Pre-sealing assessment identifies where air escapes and whether damaged ductwork needs attention first. A blower door test may also be used when relevant to determine whether duct sealing alone addresses the issue or broader building-envelope air sealing should be considered.
A measured leakage assessment shows whether hidden seams are the main problem or whether disconnected, crushed, or torn ductwork needs repair first. It also helps determine when Aeroseal, accessible manual sealing, cleaning, partial replacement, or a combined approach makes sense for the property.
A baseline duct blaster test establishes leakage in CFM before sealing begins. The final pressure test and printed report compare the starting and ending numbers so you can see the measured change.
Technicians trained on the Aeroseal process isolate registers, connect the equipment correctly, and monitor the injection on a computer display. That controlled sequence continues until the target seal rate is reached.
The work plan reflects the building, from a single-family attic system to office, warehouse, apartment, and retail ductwork. Commercial service can be arranged around low-occupancy periods, while multi-system homes are assessed and treated one system at a time.
Phoenix Duct Cleaners combines visual inspection, thermal imaging, pressure diagnostics, repair review, and controlled Aeroseal application in one documented process. The assessment identifies actual leakage and system condition before work is quoted, while final testing records the result after sealing.
Request Leakage AssessmentSupply leaks release cooled air directly into attic space that can exceed 150 degrees Fahrenheit during Phoenix summers. The occupied rooms receive less airflow even though the air conditioner keeps running.
Leaky supply runs can starve back bedrooms, bonus rooms, and upstairs spaces of airflow. Two-story homes in North Phoenix and Anthem may show an upstairs cooling imbalance that points to duct leakage rather than equipment size alone.
Return-side openings can pull hot attic air and dust into the HVAC system before the air reaches filtration. Sealing those gaps reduces that uncontrolled pathway and the extra load it places on cooling equipment.
Leaks at plenum boxes, register boots, and takeoffs may sit behind walls, above dropped ceilings, or beneath attic insulation. Mastic and foil tape cannot seal a joint that a technician cannot physically reach, which is where the interior aerosol path is useful.
Sustained attic heat, UV exposure, rodent activity, and settling over 15 to 20 years can open joints or damage flex duct. Homes built during Phoenix growth through the 1990s and 2000s may contain disconnected boots or torn sections that require repair before sealing.
When conditioned air escapes, the system runs longer to satisfy the thermostat and adds compressor wear. In multi-tenant buildings, that waste can also inflate common-area HVAC charges and operating expenses across zoned systems.
The process moves from inspection and preparation to measured sealing and final documentation. Each step helps distinguish physical duct damage from sealable air leakage and records how the system performs.
Technicians inspect accessible attic runs, plenum connections, and register boots, using thermal imaging and photographs to document suspected leaks. Crushed, torn, or disconnected sections are identified for repair before sealing.
Needed repairs and recommended cleaning are addressed before application so the duct interior is ready. Registers are sealed, and the Aeroseal machine is connected to the trunk line to isolate the duct system.
A duct blaster test measures the starting leakage rate in cubic feet per minute at a standardized pressure. That baseline becomes the reference for the computer-monitored application and final report.
The adhesive particles are introduced into the pressurized ductwork. They pass through intact runs and collect at escaping-air points, building at the edges of each opening until it closes.
A computer display tracks the declining leakage rate throughout injection. The technician watches the measurements in real time and stops the application when the target seal rate is reached.
A final pressure test measures remaining leakage after treatment. You receive a printed report comparing the before-and-after numbers, giving the home or building a documented result.
Start with a duct leakage assessment that measures system performance and identifies damaged or inaccessible connections. Phoenix Duct Cleaners can then recommend sealing, cleaning, repair, or a combined approach based on the documented condition of your ductwork.
These answers cover Phoenix Aeroseal pricing, timing, testing, preparation, alternatives, performance, and common property types. A leakage assessment is the practical way to determine what applies to a specific duct system.
Call Our TechniciansMost single-family homes in the Phoenix area run between $1,300 and $3,000, with larger or more complex systems reaching $6,900 depending on square footage and duct accessibility. Pricing is generally about $1 to $1.50 per square foot of conditioned space, or $1,500 to $2,500 per typical residential air-conditioning system. Multi-system homes are priced per unit, with common discounting on the second and third systems sealed during the same visit.
It can be worthwhile when measured duct leakage is driving long HVAC runtime, uneven cooling, or dusty return air during Phoenix's extended cooling season. Treated systems commonly show leakage reductions between 70% and 95%, while Southwest households typically see $600 to $900 in annual utility savings after sealing. Actual results depend on the starting leakage and the condition of the ductwork.
The main alternative is manual sealing with mastic and metal tape at every accessible joint. Manual work may cost less upfront, but it cannot reach leaks inside walls, above ceilings, or at buried plenum connections. When access is limited or the ductwork is damaged, manual sealing may be combined with air duct repair or partial replacement.
Aeroseal duct sealing may qualify under the federal 25C energy efficient home improvement credit, described here as covering 30% of project cost up to a combined annual cap of $1,200 for eligible improvements. Phoenix Duct Cleaners provides documentation of the work performed. Tax rules and individual eligibility can change, so confirm current requirements with IRS guidance or a qualified tax professional before filing.
Phoenix Duct Cleaners strongly recommends cleaning first and treats it as standard practice on most jobs. Removing dust, insulation debris, or contamination prevents that material from being left inside after sealing and gives the aerosol cleaner metal or liner surfaces for bonding. Sanitizing can be included with the cleaning service.
The two-foot rule generally refers to keeping at least two feet of straight duct before and after a fitting, elbow, or damper to reduce turbulence that can affect airflow readings and balance. Existing systems do not always have that spacing, so the technician accounts for tight geometry when interpreting leakage data.
A typical single-family home takes roughly half a day to a full day for baseline testing, injection, final testing, and documentation. Larger homes with multiple systems or extensive commercial branch ductwork take longer and may require a full service day per system. Commercial work can often be scheduled after hours or during low-traffic periods.
The aerosol particles travel with pressurized air through the duct system. They pass through sealed duct sections but collect at the edges of openings where air escapes, gradually building a seal. This lets the process treat concealed boot, plenum, and takeoff connections without opening the surrounding finish.
The application described by Phoenix Duct Cleaners can seal gaps up to five-eighths of an inch by building the adhesive at the opening's edges. Disconnected duct runs, crushed sections, and major tears are physical defects that need repair rather than aerosol sealing alone.
A duct blaster measures leakage in cubic feet per minute before the sealant is injected. The equipment monitors leakage reduction during treatment, and a final pressure test establishes the ending rate. The customer receives a printed report comparing the before-and-after numbers.
Yes. The process can be applied to retail centers, offices, apartment complexes, warehouses, and other buildings with large trunk lines and many branch connections. Commercial sealing is commonly planned for after-hours or low-occupancy windows, and a mid-size system may fit within one service window.
Disconnected flex duct, crushed runs, torn insulation jackets, and other significant physical damage should be corrected before aerosol treatment. The inspection also checks plenum connections and register boots, with photographs used to document areas that need air duct repair or partial replacement.
The cured sealant remains flexible through seasonal expansion and contraction rather than becoming brittle. Properly sealed systems are expected to hold for the life of the ductwork, and the source reports no measurable degradation in follow-up testing on systems five to ten years after treatment. Physical damage that occurs later is a separate repair issue.
