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.
Guardsman HVAC Cleaning in Dallas: What to Know First
CleanRun Duct Repair & Cleaning provides independent Guardsman HVAC cleaning in Dallas for homeowners who want the work photographed, priced in writing, and guaranteed for a full year. Most Guardsman evaporator coil and blower cleaning jobs are completed in a single scheduled visit, with your written price delivered before any panel comes off. We are not affiliated with or authorized by Guardsman; we are an independent service provider that documents every duct run and coil surface before and after work.
This page is for Dallas homeowners with Guardsman air handlers, heat pumps, or gas furnaces installed between 2015 and 2022, particularly those in neighborhoods like Oak Cliff, Lakewood, and the Design District where we’ve found older installations hold debris differently than newer construction. If your Guardsman system is running longer cycles, delivering weak airflow, or smelling musty at startup, the cause is often visible once the plenum (the main air distribution box) is opened and photographed. Call (469) 405-6133 for a free estimate with a written price.
How Guardsman Products Fail - and How We Fix Them
- Guardsman G-Series evaporator coils develop restricted airflow from biofilm buildup between the fins. In Dallas, where cooling runs eight months a year, the G-Series coil’s tight fin spacing traps condensation and skin cells that turn into a translucent film you can’t see from the outside. Our crew removes the coil, applies foaming cleaner designed for aluminum microchannel coils, and rinses with low-pressure water so the fins don’t flatten. The photo record shows the difference between a coil that looks clean and one that actually moves rated airflow.
- Guardsman ProAir blowers collect debris on the squirrel-cage blades that throws the wheel out of balance. The ProAir line uses a forward-curved blade design that moves high volume at low speed, which also means dust settles on the trailing edge and hardens. We see this in Lakewood homes with pets or recent remodeling. The fix is removal, media blasting with a soft abrasive, and dynamic balancing before reassembly. A wheel that vibrates wears the motor bearings prematurely.
- Guardsman HeatPro heat exchangers develop soot scaling when combustion air is restricted. The HeatPro’s serpentine design runs hotter than some competitors, which is efficient but unforgiving if return air is partially blocked by dirty ducts. We inspect with a borescope, document any scaling or cracks, and clean only if the metal integrity passes. If the exchanger is compromised, we stop and show you the image before discussing replacement.
- Guardsman Guardian condenser coils in Dallas clog with cottonwood seed and construction dust. The Guardian’s louvered fins are effective at shedding rain but trap the fine particulate that blows through the Design District in spring. We use a foaming cleaner followed by straight-line water rinse, never high pressure that folds the fins. The before photo usually shows a gray mat; the after shows the original copper color.
- Guardsman IntelliFlow air handlers suffer from clogged drain pans when algae colonizes the condensate line. The IntelliFlow’s shallow pan design and P-trap configuration can hold standing water if the vent line is blocked. In Dallas humidity, that’s algae in 48 hours. We clean the pan with an antimicrobial treatment, clear the drain with nitrogen pressure, and install a cleanout tee if the original builder didn’t include one. The photo record includes the pan interior and the flow test.
Our Guardsman HVAC Cleaning Process

- 1
Written price delivered on arrival. Haven Standard Clause 1: we put the full scope and price in writing before touching your system. No exceptions.
- 2
Diagnostic photography. We open the plenum and photograph the evaporator coil, blower wheel, heat exchanger, or condenser surface as found. You see what we see before any work is approved.
- 3
Parts decision: OEM or quality aftermarket. For Guardsman systems still under parts warranty, we use OEM when required to preserve coverage. For out-of-warranty units, we source quality aftermarket equivalents from suppliers we verify independently. The choice is documented in writing.
- 4
Cleaning with trade-specific methods. Coils get foaming cleaner and low-pressure rinse. Blowers get media blasting and balance. Heat exchangers get borescope inspection before any cleaning decision. Condensers get straight-line water, never pressure washing.
- 5
Post-work test and photo record. We run the system, measure temperature drop and static pressure, and photograph the cleaned components. The photo record is delivered as a standard job deliverable, not an extra.
- 6
365-Day Done Right Promise activated. If the work is not right, we make it right. Backed in writing, not subject to manager approval.

AfterWhat Guardsman HVAC Cleaning Costs in Dallas
| Service | Typical Range | What Moves the Price |
|---|---|---|
| Evaporator coil cleaning | $280-$420 | Coil accessibility, fin corrosion level, refrigerant recovery required |
| Blower wheel and housing cleaning | $240-$360 | Wheel removal difficulty, motor age, balance correction needed |
| Condenser coil cleaning | $180-$290 | Folding damage from prior cleanings, fin combing required |
| Heat exchanger inspection and cleaning | $320-$480 | Borescope access, scaling severity, safety stop protocol |
| Full air handler cleaning (coil + blower + pan) | $520-$740 | System size, contamination level, drain line rebuild |
These are whole-system prices, not per-vent or teaser rates that balloon once the truck arrives. The price we write is the price you pay. Factors that raise the cost: systems that haven’t been opened in 5+ years, evidence of prior DIY cleaning with damaged fins, or access panels that have been sealed shut by paint or caulk.

Why Dallas Homeowners Call CleanRun Air Duct Cleaning Dallas for Guardsman Work

We’ve been running jobs across Dallas since 2013, including properties near the Design District where older buildings hold dust and debris in ways newer construction doesn’t. Tomas Reyes, our owner, picked up his trade skills at Suffolk County Community College and spent the better part of two decades learning what actually lives inside ductwork and air handlers. His approach is simple: show the duct first, talk about the solution second.
Every Guardsman job gets the same documentation we apply to Lennox, Trane, and Carrier systems we also service. That means the photo record, the written price, and the 365-Day Done Right Promise are standard, not optional. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews. The equipment on every truck includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman-branded tools you can verify independently. If you have a written estimate from another company, we provide a Free Second Opinion at no cost, with our number written next to theirs.
FAQs
No, routine cleaning by a qualified independent technician does not void your Guardsman warranty, provided no components are altered or damaged during service. We document our methods and use OEM parts when required for warranty preservation. If your system is still under parts coverage, we note that in your written scope and select accordingly. Call (469) 405-6133 if you need help reading your warranty terms.
You receive a Documented Photo Record of every component we cleaned, included as a standard deliverable on every job. The before-and-after images show the coil surface, blower wheel, or heat exchanger as found and as left. This practice has been standard for us since 2013 because a customer with a photograph doesn’t need to trust a verbal report. If a company won’t show you the inside of your own system, that tells you something.
Replace if the heat exchanger is cracked, the evaporator coil has multiple leaks, or repair costs exceed 40% of replacement value for a unit over 12 years old. Clean and repair if the failure is isolated to a cleanable component and the system has reliable refrigerant integrity. We give you the borescope images, the static pressure readings, and the written price for both paths so you decide from evidence, not pressure. Call (469) 405-6133 for an honest assessment.
For systems under active parts warranty, yes, OEM is required to preserve coverage. For out-of-warranty units, quality aftermarket equivalents from verified suppliers perform equivalently at lower cost. We source both, document which we used, and explain the trade-off in writing before ordering. The decision is yours, not ours by default.
Every 3 to 5 years for the evaporator coil and blower, annually for the condenser if you have cottonwood or construction dust exposure, and immediately if you notice musty startup odors or extended run cycles. Dallas cooling loads run heavy from April through October, which accelerates biofilm on coils and debris on blowers. We inspect and advise based on what the camera shows, not a calendar.
Ready to see what’s actually inside your Guardsman system? Call (469) 405-6133 for a free estimate with a written price delivered before any work begins. We’ll show you the duct first, then talk about what needs to happen next.
