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 Covington
HVAC cleaning in Covington, WA typically runs $450 – $850 for a complete system cleaning, including the evaporator coil, blower motor, supply and return ducts, and air handler. Most Covington homes are finished same-day or next-day, depending on system size and how much the coils have fouled. We know the housing stock here from Jenkins Creek to the Plateau subdivisions, and we know what hides inside those systems. Call (737) 727-2314 and Omar Haddad will walk you through exactly what your home needs, with a written price before any work starts.
Why Cardinal Air Duct Cleaning Is Covington’s Preferred HVAC Cleaning Company
Covington homeowners deal with a specific set of HVAC problems: original flex duct runs in 1990s builds near Jenkins Creek, sagging low spots that collect lint, and return-side dust loads that surprise people. Our teams work these systems weekly. We’re part of the Relay Home Co. family, founded 2005, and every job runs under the 365-Day Done Right Promise – if the work isn’t right within 365 days, we return and correct it at no charge. That applies to every booking without exception.
You’ll know your technician’s name before they arrive. They’re background-checked, uniformed, and they carry professional-grade equipment – Rotobrush brush systems for agitation, Nikro HEPA vacuums for negative-pressure extraction. That means the loosened debris goes straight into the vacuum, not back into your living room. Every job also includes a written price handed to you before a single duct is touched, and before-and-after photos of your own system. No guessing. No phone tag. A live person answers our phones 24/7.
Evaporator Coil Cleaning in Covington
Evaporator coil cleaning in Covington homes is the single highest-impact service we perform, because the coil sits inside the air handler and collects a matted layer of lint, dust, and sometimes pet hair that chokes airflow and forces your AC to run longer. Most Covington homeowners don’t realize their coil was never cleaned because the previous service skipped the air handler entirely. When the coil loads up, your system loses cooling capacity and your energy bill creeps up. A full evaporator coil cleaning in Covington generally runs $200 – $350 as part of a complete HVAC cleaning.
We pull the air handler panel, inspect the coil, and use agitation tools plus a HEPA vacuum to remove the encrusted layer without damaging the fins. After cleaning, we treat the coil with a protective treatment that slows future buildup. If the coil is badly fouled, the difference in airflow is immediate – you feel it at the registers the same evening.
When Your Coil Needs Attention
Covington systems that pull return air from crawlspaces or garages under the main floor bring in more dust than slab-on-grade homes in neighboring cities. That dust settles on the coil first. If your AC runs fine but the air feels weak or the system short-cycles on hot days, the coil is the first place we look.
Coil Treatment After Cleaning
Once the coil is clean, we apply a coil treatment that keeps the surface slick and less likely to re-foul during the next cooling season. It’s a small step that adds months of clean airflow to your system. We recommend coil cleaning as part of every HVAC Cleaning visit, not as an optional add-on.
AC Duct Cleaning in Covington
AC duct cleaning in Covington tackles the supply and return runs that carry conditioned air through your home. The older two-story builds near Jenkins Creek often still have original flex duct runs that sag in the low spots, and those low spots catch lint, construction debris, and occasionally rodent droppings from the crawlspace. A complete AC duct cleaning for a typical Covington home runs $350 – $550, depending on the number of runs and whether the air handler and blower are included. We quote one flat price per system, agreed before we start.
We don’t do per-vent pricing. Counting registers after the crew arrives is how Covington homeowners get surprised with a bigger invoice than the phone quote. Our written price covers the whole system – supply runs, return runs, air handler, blower, and coil – and it does not change at the door.
Source Removal, Not Just Vacuuming
We recently worked a two-story home off SE 272nd St near the Jenkins Creek trailhead where the homeowner complained of dust blowing from the registers whenever the AC kicked on. Our tech pulled the air handler panel, found a matted lint pathway across the evaporator coil, and used agitation tools plus negative pressure with HEPA filtration to do a full source removal on the supply and return ducts. After cleaning the blower motor and reinstalling the registers, we showed the homeowner before-and-after photos of their own ducts – no per-vent pricing, one flat price agreed before we started.
Trusted Brands We Service in Covington
We service all major equipment brands in Covington homes – Carrier, Lennox, Trane, Goodman, Rheem, and more – and we stock common replacement parts locally so turnaround is fast. Our filtration recommendations include Aprilaire and Guardsman products, and our cleaning fleet runs Abatement Technologies containment units on larger jobs. When a Covington customer calls about a specific system, our team knows the unit’s typical failure points because we’ve worked on dozens of the same models throughout the 98042 and 253 area.
Common HVAC Cleaning Problems We See in Covington Homes
- Sagged flex duct runs in 1990s two-story builds. Original ductwork near Jenkins Creek and along 132nd Ave SE often sags between supports, creating low spots that trap lint and restrict airflow. We re-support or replace those runs when cleaning alone won’t restore flow.
- Return air pulling from crawlspaces and garages. Many Covington systems draw return air from under the main floor, which means the return side loads up with dust faster than homes with slab foundations. The coil and blower take the hit first.
- Air handler and blower motor skipped by previous cleaners. On 1990s Covington homes, the real debris load sits behind the coil, not just in the visible runs. Skipping the air handler leaves half the problem untouched.
- Per-vent pricing surprises on Plateau homes. Larger two-story homes in the Plateau subdivisions have a lot of registers, and per-vent pricing turns a $350 phone quote into a $700 invoice once the crew starts counting. We quote one flat price per system, agreed before we start, and it doesn’t change.
