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.

AfterFast, Reliable HVAC Cleaning Across Krum
HVAC cleaning in Krum typically costs between $450 and $900 for a full system, depending on home size and how much buildup has accumulated. Most jobs are completed in three to five hours, and you’ll get a written price before we touch a single duct. If you live anywhere from the neighborhoods off FM 1173 down to the newer subdivisions near Krum High School, we can usually schedule you within a few days. Call (737) 727-2314 and a live person answers. No voicemail loops, no phone tag.
We know Krum homes because we work in them every week. The combination of Cross Timbers pollen, open pasture dust, and the hard water that runs through evaporator coils here creates a specific kind of buildup that generic cleaning crews don’t always recognize. Our HVAC Cleaning team runs professional-grade equipment, including Rotobrush agitation systems and Nikro HEPA vacuums, and we document everything with before-and-after photos. You see exactly what we pulled out. That’s the whole point.
Why Cardinal Air Duct Cleaning Is Krum’s Preferred HVAC Cleaning Company
Three things matter to Krum homeowners when they book us: a real price, a real person, and proof the work happened. We deliver all three on every job. Omar Haddad runs the team with one simple rule: if the work isn’t done right within 365 days, we come back and fix it at no charge. No fine print, no exclusions. That’s the 365-Day Done Right Promise, and it covers every booking without exception.
Krum customers consistently mention the same things in reviews. The written price handed over before work starts. The technician arrived in uniform with a name they already knew from the booking. And the before-and-after photos showed the actual ducts in their actual house, not a stock image. The Relay Standard is part of how we operate: you get a live trackable arrival window, photo documentation, and a digital invoice you can pay from your phone. That’s what booking a home service should feel like in 2026.
Response time to Krum is straightforward. Scheduling and dispatch are coordinated from our Dallas-Fort Worth office, and crews serve Krum locally throughout the week. Most Krum jobs get scheduled within two to four business days. If you’re calling about a system that’s making noise or pushing musty air through your registers, we’ll get you on the schedule as fast as the calendar allows. Call (737) 727-2314 and we’ll give you an honest picture of when we can be there.
AC Duct Cleaning in Krum
AC Duct Cleaning in Krum means pulling the pollen, pasture dust, and lint mat that settles into your return ducts and air handler, not just wiping down the visible supply registers. Because Krum sits on the eastern edge of the Cross Timbers, where blackjack and post oak give way to open pasture, spring and fall pollen loads here are among the heaviest in Denton County. Your HVAC system pulls that fine organic dust into the return ducts constantly, and it coats blower wheels faster than most homeowners realize. A full AC duct cleaning for a typical Krum home runs $450 to $800, depending on system size and buildup.
Evaporator Coil Cleaning
Your evaporator coil sits above the furnace or inside the air handler and gets cold while the system runs. Dust sticks to wet coil fins, hardens, and chokes airflow. In Krum, where summer air conditioning runs hard from May through September, coil buildup directly raises your electric bill. We clean the coil faces with professional coil cleaners, not water spray that pushes debris deeper. Coil treatment and cleaning for a standard system runs $150 to $300, often bundled with a full duct cleaning.
Blower Cleaning and Condenser Work
The blower wheel pulls air through the return, and that’s exactly where the dense Cross Timbers pollen accumulates. A matted blower wheel strains the motor and reduces airflow at every vent. We remove the blower assembly, clean the wheel and housing, and verify airflow readings before we put it back. Outside, condenser coils packed with cottonwood and pasture debris get cleaned with proper coil chemicals and fin care. Condenser cleaning in Krum runs $120 to $250 depending on unit access and how long it’s been since the last cleaning.
Furnace Cleaning in Krum
Furnace Cleaning in Krum is about more than the visible vents. When the furnace runs through winter, it pulls dry air and fine dust through the return drop, past the blower, and across the heat exchanger. A family on Highland Park Drive called us after their air handler started humming and the supply registers began pushing a faint musty smell through the house. A camera inspection showed a heavy mat of pollen and lint coating the blower motor and a clogged return drop. We set up negative pressure with HEPA filtration, ran agitation tools through the supply and return ducts, and pulled everything out with source removal. The hum disappeared and airflow measured back to normal. Furnace cleaning for a typical Krum home runs $400 to $750.
Heat Exchanger Cleaning
A dusty heat exchanger doesn’t just smell. It can trip the limit switch, cause short cycling, and in the worst cases, crack. We inspect and clean the exchanger surfaces as part of a full furnace cleaning, and we photograph the condition before and after so you can see exactly what was there. This isn’t a quick vacuum pass. It’s the difference between a system that runs clean and one that keeps recirculating the same dust all winter.
Air Handler Cleaning
The air handler is the big metal box in a closet, attic, or garage that houses the blower, coil, and filter. In the smaller homes common around downtown Krum and the older splits near the railroad district, these units are often tight-access installations. We clean the interior surfaces, drain pan, and blower assembly, then check the condensate line so you don’t end up with a water stain on the ceiling come July. Air handler cleaning runs $180 to $350 on its own.
Trusted Brands We Service in Krum
We service and clean every major residential HVAC brand found in Krum homes: Carrier, Trane, Lennox, Goodman, Rheem, American Standard, and more. Because our techs carry common filters, coil cleaners, and drain line supplies on the truck, most Krum jobs get completed in a single visit without waiting on parts runs. We also stock Guardsman filtration products and Aprilaire filter upgrades for homeowners who want better protection against the pollen that blows in from the Cross Timbers. Omar Haddad’s crews run Rotobrush agitation systems, Nikro HEPA extraction units, and Abatement Technologies containment when the job calls for it. You’ll know exactly what tools are coming before the tech parks the van.
Common HVAC Cleaning Problems We See in Krum Homes
- Pollen-caked blower wheels. Krum’s spring bloom from the Cross Timbers produces some of the heaviest pollen loads in Denton County, and blower wheels collect it fast. When the wheel gets caked, airflow drops and rooms at the end of long duct runs stay five degrees warmer than the rest of the house.
- Clogged return drops from pet hair and lint. Homes around Krum with indoor pets see return ducts lined with a dense mat of hair, dander, and fine dust within two years of the last cleaning. This forces the blower to work harder and pushes that faint musty smell through the registers.
- Per-vent bait pricing from other companies. We regularly hear from Krum homeowners who got a low per-vent quote only to have the price balloon once the crew counted registers, added a furnace fee, and tacked on filter charges. We price one flat rate for the whole system before we start. Written down. It does not change at the door.
- Dirty condenser coils from pasture debris. Homes on the east side of Krum near open pasture land deal with windblown grass clippings, cottonwood seed, and fine grit packing the outdoor condenser coils. A choked condenser runs hotter, uses more electricity, and shortens compressor life. We clean these as part of a full HVAC cleaning or as a standalone service.

FAQs About HVAC Cleaning in Krum
How often do Krum homes actually need HVAC duct cleaning?
Most Krum homes genuinely need a full HVAC cleaning every three to five years, although homes with heavy Cross Timbers pollen exposure, multiple indoor pets, or recent construction nearby may benefit from every two to three years. The honest answer is that not every system needs it annually. If we inspect your ducts and they’re clean, we’ll tell you that and recommend waiting. Call (737) 727-2314 if you want an honest assessment, not a sales pitch.
Do you charge per vent or one flat price for HVAC cleaning in Krum?
One flat price per system, agreed in writing before any work starts. We do not charge per vent, per register, or per duct run. That pricing model is exactly how the low-ball bait-and-switch companies trap homeowners. Your written price covers the entire system: supply and return ducts, air handler, blower, and coils. If we find something outside that scope, we show you photos and give you a separate written quote before touching it.
What does an HVAC cleaning actually involve, just vacuuming the vents?
No. A proper HVAC cleaning uses negative-pressure extraction paired with mechanical agitation. Negative-pressure extraction means the loosened debris goes straight into the HEPA-filtered vacuum, not back into your living room. We run Rotobrush agitation tools through the supply and return ducts, remove the blower assembly and clean the wheel and housing, and clean the evaporator coil and drain pan. Then we photograph everything before and after so you can see the interior of your own ducts. A shop vac on a vent register is not duct cleaning.
Can you clean my furnace and AC ducts at the same time?
Yes, and in most Krum homes it’s the smarter move. The furnace and AC share the same air handler, blower, and ductwork, so cleaning both at the same time means one system-wide job, one flat price, and one set of before-and-after photos. We do the full interior: supply ducts, return drop, blower, evaporator coil, heat exchanger surfaces, and condensate line.
Will duct cleaning help with the pollen and dust we get in Krum each spring?
Yes, with a caveat. Cleaning removes the accumulated pollen mat and dust load that your system has already trapped, and upgrading to a higher MERV filter helps catch more of what’s coming in. But if your return ducts have gaps, or the filter bypasses air around its housing, the system will keep pulling in unfiltered outdoor air. We check for those gaps during every cleaning and show you photos if we find them. Call (737) 727-2314 for a free estimate and a straight answer on what your system actually needs.
