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 HVAC Cleaning in Denver: What to Know First
CleanRun Duct Repair & Cleaning provides independent Guardsman HVAC cleaning in Denver, with most evaporator coil, blower, and condenser jobs completed in a single scheduled visit. We deliver a written price before any work starts, and every job ends with a documented photo record of what was found and what was done. If you own a Guardsman air handler, heat pump, or packaged unit in Capitol Hill, Cherry Creek, or anywhere in the Denver metro, call us at (720) 799-2292 for a free estimate with no obligation.
How Guardsman Products Fail - and How We Fix Them
- Guardsman G-Series evaporator coils develop restricted airflow from compacted pollen and cottonwood debris. Denver’s spring cottonwood season, particularly along the South Platte corridor, loads fine mesh into these coils faster than standard pleated filters can catch. We remove the coil assembly, apply foaming cleaner designed for aluminum micro-channel construction, and photograph the pressure-drop improvement on our manometer before reassembly.
- Guardsman H-Series heat exchangers show soot scaling in homes with older galvanized duct runs. Incomplete combustion often traces back to blower wheels caked with construction dust from Denver’s 2015-2020 building boom. We pull the blower, clean the squirrel cage blade-by-blade, and scope the heat exchanger with a borescope camera to document integrity before the burners relight.
- Guardsman packaged units on Denver flat roofs suffer condenser fin corrosion from hail and de-icing salt aerosol. The GPH14 and GPH16 series use louvered coil guards that trap granular debris against the aluminum. We disassemble the guard panels, straighten fins with a comb matched to the fins-per-inch count, and apply a non-acidic foaming treatment that won’t void remaining warranty coverage.
- Guardsman variable-speed blower motors in the GVM series throw error codes when Hall-effect sensors read debris buildup as mechanical failure. The motor rarely fails; the optical sensor window does. We clean the sensor housing with electronics-grade solvent, verify RPM feedback with a tachometer, and only quote motor replacement if the bearing test fails.
- Guardsman TXV bulbs in heat pump systems lose calibration from oil sludge migration. This shows up as insufficient superheat in summer and frosting in winter, especially in Denver’s low-humidity, high-UV climate where refrigerant seals age faster. We clean the bulb mounting surface, reinsulate with closed-cell foam, and verify charge by weight rather than pressure alone.
Our Guardsman HVAC Cleaning Process
- 1
Written estimate on arrival. Haven Standard Clause 1: we inspect the Guardsman model plate, note the series and manufacture date, and deliver a fixed price before touching a panel screw.
- 2
Diagnostics with documentation. We photograph the evaporator, blower, and condenser (or heat exchanger, for furnaces) as-found, then show the customer before proceeding. Here is what the camera found. Here is what it costs to fix it. You decide.
- 3
Parts decision: OEM or verified aftermarket. Guardsman OEM coils and blower wheels are available through our distributor with next-day Denver delivery. For discontinued G-Series components, we source aftermarket equivalents that match the original pressure-drop and amp-draw specs, documented in writing.
- 4
Cleaning and repair. Negative-pressure extraction on the duct side; foaming cleaner and pressurized rinse on the coil side; hand-cleaning on blower wheels and housings. We use Rotobrush and Nikro equipment, with Abatement Technologies HEPA containment when mold is suspected.
- 5
Performance test and photo record. Static pressure, temperature split, and amp draw recorded on a printed job ticket. Before-and-after photos of every cleaned component delivered by email before the crew leaves.
- 6
365-Day Done Right Promise activated. The written guarantee goes into the customer’s file, not a drawer. If the same fault code returns, we return.

Every price is per system, agreed in writing, with no per-vent add-ons or trip-charge surprises. Call (720) 799-2292 for an exact quote on your Guardsman unit. Estimates are free.
Why Denver Homeowners Call CleanRun Duct Repair & Cleaning for Guardsman Work
We are an independent Guardsman service provider, not a factory-authorized dealer, which means we work on the unit you own without pushing a replacement sale. Tomas Reyes and our crew have cleaned Guardsman equipment in Denver since 2013, including original installations in Capitol Hill Victorians where the ductwork predates the HVAC by a century. We also service Lennox, Trane, and Carrier systems, so when a home has mixed brands or a recent replacement left mismatched components, we recognize the interaction problems.
The 365-Day Done Right Promise is backed in writing on every job. The documented photo record is standard, not an upsell. And every technician is background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews.
FAQs
No. Warranty coverage requires that maintenance be performed by qualified technicians using appropriate methods; it does not require factory-authorized status. We document our procedures and products used, and we note any warranty-critical specifications, such as fin comb count or refrigerant type, on your job ticket. If a factory dispute arises, you have written evidence of proper service. Call (720) 799-2292 if you need documentation for a warranty claim.
Cleaning is the right choice when the heat exchanger is intact, the coil has no refrigerant leaks, and the blower motor draws within 10% of nameplate amps. We check all three with a borescope, electronic leak detector, and clamp meter during our inspection. Replacement becomes the honest recommendation when the heat exchanger has a crack, the coil has multiple pinholes, or the blower motor bearing test fails. We show you the evidence and quote both options when the line is close. Call (720) 799-2292 for an assessment.
Yes, for most units manufactured after 2010. Guardsman G-Series and H-Series coils, blower wheels, and control boards remain in distribution through our Denver supply house with next-day availability. For units manufactured between 2005 and 2010, some components require aftermarket cross-reference, which we verify for pressure-drop and electrical compatibility before installation. We do not guess on fit. Call (720) 799-2292 with your model number and we will confirm parts status before scheduling.
Every three to five years for the evaporator coil and blower in homes with standard filtration and no pets. Every two to three years if you have multiple pets, live near active construction, or run the system without a MERV 8 or higher filter. Denver’s dry climate and high UV reduce biological growth but increase dust loading, so the coil typically cakes with particulate rather than mold. We inspect and advise rather than sell a calendar schedule. Call (720) 799-2292 to discuss your specific system usage.
A complete job record: before-and-after photographs of every cleaned component, static pressure and temperature-split readings, amp draw measurements, the written scope of work, and the 365-Day Done Right Promise. Everything is delivered by email before the crew leaves your driveway. This is Haven Standard Clause 2: Documented Delivery, and it has been our practice since our first job in 2013. Call (720) 799-2292 to schedule a job with full documentation.
