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.

AfterAir Duct Cleaning in Allen, TX
Full-system HVAC cleaning in Allen typically runs $380-$720 for a two-story home with multiple zones, and every job starts with a written price before any panel comes off. Allen’s large suburban homes built during the 1995-2010 boom carry 300-500 linear feet of flex duct through unconditioned attics that regularly hit 150°F in summer, accelerating liner breakdown and debris accumulation. We dispatch crews from our Dallas-Fort Worth office and coordinate scheduling for Allen addresses directly. Call (940) 290-8552 for a written estimate.
Why Allen Homes Are Different
Allen underwent one of the fastest suburban buildouts in the country from the mid-1990s through the 2010s, which means a huge share of its housing stock is now 15-30 years old. That’s exactly when original flexible ductwork in large two-story tract homes begins to sag, delaminate, and accumulate heavy debris loads. Unlike older Dallas suburbs where duct problems are already well-known, Allen homeowners often don’t realize their “newer” home’s ductwork is already past its serviceable life.
The typical Allen home runs 2,800-4,500 square feet with multiple zoned HVAC systems and extensive flex-duct runs through unconditioned attic spaces. Spring pollen from the Blackland Prairie corridor is severe here, and in communities like Twin Creeks, homeowners on streets completed in the early 2000s lived with active construction on adjacent lots for years. That sustained disturbance pulled Collin County clay dust and cellulose insulation debris into return-air systems, leaving visible grey-brown buildup on evaporator coils that our crews encounter far more consistently than in fully built-out suburbs.
Our Main Allen Services
Allen homeowners call us most often for these three services, each with its own dedicated page and detailed pricing.
Air Duct Cleaning in Allen
We clean every duct run with negative-pressure extraction, photographing the interior before and after each pass. In Allen’s large homes, this means accessing multiple attic drops, checking for sagging flex at elbows and junctions, and documenting any delamination we find. The photo record is included as a standard deliverable on every job. Air Duct Cleaning in Allen covers full pricing and what’s included.
Dryer Vent Cleaning in Allen
Dryer vent blockages in Allen’s two-story homes often occur at the long vertical runs common in these floor plans. We pull the vent line, rotary-brush the full length, and airflow-test before and after. Lint accumulation at the roof termination is a frequent finding here due to the height and run length. Dryer Vent Cleaning in Allen has full details.
Duct Repair & Sealing in Allen
Sagging flex duct, separated inner liners, and failed tape seals are standard findings in Allen’s 15-30 year old systems. We repair or replace damaged sections with new flex or hard pipe where appropriate, then seal all joints with mastic. Every repair is photographed and the scope is written before work begins. Duct Repair & Sealing in Allen explains our process.

BeforeAfterHVAC Cleaning in Allen
Allen homes from the 1995-2010 buildout carry complex HVAC systems with multiple air handlers, extensive flex-duct networks, and evaporator coils that have been collecting Blackland Prairie pollen and construction-era debris for 15-30 years. The photo record we deliver shows exactly what was on those coil faces and blower wheels before we touched them. HVAC Cleaning covers our full equipment and methods.
Evaporator Coil Cleaning
Signs you need it
Ice buildup on the refrigerant lines, weak airflow from registers, or a musty smell when the AC first cycles on.
What it costs in Allen
Evaporator coil cleaning in Allen typically runs $180-$340 per air handler.
How we do it
We remove the access panel, apply foaming cleaner to the coil face, rinse with low-pressure water to protect the fins, and photograph the before and after condition.
Blower Cleaning
Signs you need it
Uneven heating or cooling across zones, a humming motor that struggles to reach speed, or dust puffing from registers at startup.
What it costs in Allen
Blower wheel and housing cleaning in Allen typically runs $140-$260 per unit.
How we do it
We pull the blower assembly, clean the wheel vanes and housing with compressed air and solvent, balance the wheel, and reinstall with a fresh filter.
What HVAC Cleaning Costs in Allen
| Item | Typical range in Allen |
|---|---|
| Evaporator coil cleaning (per air handler) | $180-$340 |
| Blower cleaning (per unit) | $140-$260 |
| Full system cleaning (coil, blower, ducts, 1 zone) | $380-$720 |
How do I know the HVAC cleaning was actually done?
Every duct run, coil face, and blower wheel is photographed before and after, and the images are delivered as part of your job record under Haven Standard Clause 2: Documented Photo Record. You see what was there and what changed, not just a verbal report.
Why does my Allen home need HVAC cleaning more often than my parents’ house?
Your 2,800-4,500 square foot Allen home likely has 300-500 linear feet of flex duct in a 150°F attic, plus construction debris from the 2000s buildout that older neighborhoods never experienced. The system volume and local conditions create a different maintenance profile than a 1970s ranch with hard duct and no adjacent-lot construction history.
Air Quality & Sanitizing in Allen
Allen homes from the 1995-2010 boom carry flex duct with delaminating liners that release insulation fibers and trap pollen, while 150°F attic temperatures create humid conditions at the evaporator that support microbial growth on coil faces and in drain pans. We treat these conditions with documented before-and-after photo records and written scopes under Haven Standard Clause 1. Air Quality & Sanitizing covers our full protocol.
Mold Treatment
Signs you need it
Visible black or grey spotting on the evaporator housing, a persistent earthy smell from registers, or allergy symptoms that worsen when the system runs.
What it costs in Allen
Mold treatment for evaporator and plenum in Allen typically runs $280-$520 per air handler.
How we do it
We apply an EPA-registered antimicrobial to the coil, plenum, and accessible duct surfaces, then HEPA-vacuum the residue and photograph the treated areas.
UV Light Installation
Signs you need it
Repeated mold recurrence after cleaning, or a home with occupants sensitive to airborne microbes where prevention matters.
What it costs in Allen
UV-C light installation in Allen typically runs $340-$580 per air handler, including the lamp and power supply.
How we do it
We mount a UV-C lamp in the supply plenum upstream of the coil, wire it to the air handler’s 24V circuit, and show you the installation in the photo record.
What Air Quality & Sanitizing Costs in Allen
| Item | Typical range in Allen |
|---|---|
| Mold treatment (per air handler) | $280-$520 |
| UV-C light installation (per air handler) | $340-$580 |
| Bacteria sanitizing (whole system, 1 zone) | $220-$420 |
Does UV light actually prevent mold in Allen’s climate?
UV-C lamps inhibit microbial growth on the coil and in the drain pan, which is where Allen’s high attic temperatures and humidity create favorable conditions. It’s a preventive measure, not a cure for existing contamination, and we note the lamp’s expected lifespan in your written scope.
What’s the difference between sanitizing and cleaning?
Cleaning removes visible debris and buildup; sanitizing applies an antimicrobial agent to reduce biological loading on surfaces. In Allen homes with 15-30 year old flex duct, we often recommend both, and we photograph each step so you can see what each process addressed.

What Allen Customers Say

- Petra K."The dryer vent was almost completely blocked with lint. They showed me the photograph and I understood immediately why the dryer had been running twice."
