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.

Why Cardinal Air Duct Cleaning Is Medical Lake’s Preferred HVAC Cleaning Company
Medical Lake homeowners deal with a specific kind of duct contamination, and we built our process around it. The basin geography here traps cottonwood and pine pollen that drifts in from the Spokane Valley, and it settles into supply and return ducts as a fine, sticky film. Our HVAC Cleaning crews carry Rotobrush agitation tools and Nikro HEPA vacuums so loosened debris goes straight into containment, not back into your living room.
Omar Haddad leads our Medical Lake service team. Every technician arrives background-checked and in uniform, and you’ll know their name before they knock. We don’t run a generic checklist. We know which flex duct runs in the area’s older ramblers sag and trap debris at the low points, and we inspect those spots with a camera before we quote anything.
Part of the Relay Home Co. family since 2005, Cardinal operates under The Relay Visibility Guarantee. That means a live trackable arrival time, photo proof of the work, and a digital invoice payable from your phone. One flat price per system, agreed before we touch a single register.
Furnace Cleaning in Medical Lake
Furnace cleaning in Medical Lake is the service most homeowners call us about first, usually after a dusty winter where the blower ran for months pulling air through a filter that wasn’t catching everything. The job involves pulling the blower assembly, cleaning the blower wheel and housing by hand, vacuuming the heat exchanger surfaces, and clearing the evaporator coil if it sits above the furnace. In Medical Lake’s older homes, we often find the blower packed with a gray mat of dust and pollen that reduces airflow and makes the system work harder than it should.
A typical furnace cleaning in Medical Lake runs $300 – $500. That covers the blower, heat exchanger, and the air handler interior, with a written price before we start. The 365-Day Done Right Promise applies: if anything isn’t right within a year, we return and correct it at no charge.
Blower and Heat Exchanger Work
We remove the blower wheel and clean it with a soft brush and vacuum, not a pressure washer. The heat exchanger gets a careful vacuum pass over every cell. In Medical Lake’s heating season, this is where fine ash and pet dander accumulate fastest.
Coil Treatment
When the evaporator coil above the furnace catches pollen, it forms a paste that blocks airflow. We apply a coil treatment that breaks that film down and rinses it away into the drain pan, which we also clear. This is the part that restores AC performance in summer.
AC Vent Cleaning in Medical Lake
AC vent cleaning in Medical Lake focuses on the supply and return runs that carry conditioned air through your home. The supply registers push air out; the return pulls air back to the air handler. Both collect the same fine pollen and pine needle debris, but the return side is usually worse because it draws from the whole house. We remove each register, run a brush down the run under negative pressure, and clean the register grill itself before putting it back.
Most Medical Lake homes need AC vent cleaning every 3 – 5 years, not annually. If you run your AC from late May through September and have pine trees within two blocks, you may be closer to the 3-year mark. Plan on $200 – $350 for a full vent and duct cleaning as part of a complete HVAC package.
Supply and Return Run Cleaning
We work run by run. A HEPA vacuum is connected at the air handler so the whole system stays under negative pressure while the brush works. This means debris gets pulled toward the vacuum, not pushed out of the register and into the room.
Proof of the Work
Before and after photos of your own registers and duct interiors are standard on every job. You’ll see the difference in the same spot, not a stock photo we downloaded. That’s the Relay Standard, and it’s how you know the work was actually done.
Trusted Brands We Service in Medical Lake
HVAC cleaning in Medical Lake covers every major brand installed in the area: Carrier, Trane, Lennox, Rheem, Goodman, and Bryant systems. We also stock common filtration parts from Honeywell and Aprilaire, and Guardsman treatments for coil protection. If your air handler is a 20-year-old unit tucked into a crawlspace on the north side of town, we’ve cleaned dozens like it. We don’t care what brand it is, we care that it’s actually clean when we leave.
Common HVAC Cleaning Problems We See in Medical Lake Homes
- Pine needle buildup in return drops. The pines along South Hallett Street and the lake’s east shore shed needles that get pulled into return air cavities. We’ve pulled out enough to fill a five-gallon bucket from a single rambler.
- Torn flex duct liners from bad prior cleanings. Cheap crews run a spinning brush through flex duct and shred the inner liner. We see this often in homes built in the 70s and 80s around the lake. The result is a lint pathway collecting debris faster than before.
- Sagging flex runs that trap debris at low points. The older housing stock in Medical Lake often has flex duct runs that have been re-routed or patched. Debris settles in the sag, and only a camera inspection finds it.
- Cottonwood pollen matting on evaporator coils. The basin traps spring cottonwood fluff, and it sticks to damp coils, creating a paste that drops airflow by 30% or more. This is the most common cause of weak AC airflow we correct in Medical Lake.
Pricing for HVAC Cleaning in Medical Lake, WA
A complete HVAC cleaning for a standard Medical Lake home runs $450 – $850. Furnace cleaning alone is $300 – $500. AC vent and duct cleaning alone is $200 – $350. Evaporator coil cleaning adds $150 – $250 when it’s not included in the furnace package. The price is set before we start, it does not change at the door, and it is one flat price per system, not a per-vent quote with add-ons.
What changes the cost is system size, access, and how long it’s been since the last cleaning. A two-story house with ductwork in the attic costs more than a single-story rambler. You’ll know the exact number before we open the first register. Call (737) 727-2314 for a free estimate.

FAQs About HVAC Cleaning in Medical Lake
Every 3 – 5 years, unless you have heavy pine or cottonwood around your property, which pushes you closer to 3. The reason we don’t recommend annual cleaning is simple: ducts don’t get dirty that fast, and anyone pushing yearly service is selling you a calendar, not a clean system. Call (737) 727-2314 and we’ll give you an honest read on whether it’s time.
Because per-vent pricing is a bait tactic. A low per-vent number sounds cheap until the van pulls up and the price suddenly includes “extra runs,” “sanitizing spray,” or a per-register fee that doubles the invoice. We quote one flat price per system before we start, and that number does not move. That’s the whole point of a written price.
Furnace cleaning covers the equipment itself: blower, heat exchanger, evaporator coil, and the air handler interior. AC vent cleaning covers the duct runs and registers that carry air through the house. They overlap at the air handler, but one cleans the machine and the other cleans the pathway. Doing both gets the system actually clean.
Yes, we clean dryer vents, and in Medical Lake it’s necessary because the same pollen and lint particles that clog your HVAC ducts also build up in dryer exhaust. A clogged dryer vent is a fire hazard, plain and simple. We run a rotary brush through the full length and verify airflow at the exterior vent before we call it done.
Yes. Every job includes a camera inspection before we start and before-and-after photos of your own registers and duct interiors after we finish. You’ll see the pine needles, the pollen mat, and the dust layer, and then you’ll see those same spots clean. If you want, we’ll walk you through the photos while the equipment is still running. Call (737) 727-2314 for a free estimate and a written quote before any work begins.
