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 Los Angeles
HVAC cleaning in Los Angeles means pulling years of accumulated dust, pet dander, and construction debris out of the system that moves air through your home. For most LA houses, that’s a full cleaning of the air handler, blower motor, evaporator coil, condenser, and all duct runs, with a flat price for the system agreed to before we start. We’re Cardinal Air Duct Cleaning, part of the Relay Home Co. family, and our Los Angeles crews know exactly what hides inside older stucco bungalows in Highland Park, hillside homes in Mount Washington, and everything in between. Call (737) 727-2314 for a written quote, no obligation.
Why Cardinal Air Duct Cleaning Is Los Angeles’s Preferred HVAC Cleaning Company
Los Angeles homeowners don’t have time for vague estimates or a technician who shows up and doubles the price at the door. That’s why every booking through us runs on The Relay Standard: you get a live trackable arrival window, a written flat price for your system before any work begins, and before-and-after photos of your own ducts, delivered to your phone. We don’t do per-vent pricing, and we don’t change the number once the van is parked in your driveway.
Our techs are background-checked and arrive in uniform, so you know exactly who’s walking into your home. They run professional-grade equipment from Rotobrush and Nikro, not a truck-mounted shop vac. And because most LA homes run heating only a few weeks per year, we know the dust load inside air handlers and return ducts here is heavier than in colder cities. Omar Haddad leads our Los Angeles operation and personally reviews every before-and-after photo set that leaves our jobsite tablets. We’re the HVAC Cleaning crew local homeowners actually recognize when we pull up.
AC Coil Cleaning in Los Angeles
AC coil cleaning in Los Angeles is not optional maintenance. The evaporator coil sits inside your air handler and pulls heat out of the air. In a city where the AC runs from May through October, that coil gets coated in a sticky film of dust, pet hair, and the fine particulates that drift up from the 110, 5, and 10 freeway corridors. Once that film builds up, your system works harder, your energy bill climbs, and the air moving through your home passes over a dirty surface every single cycle. A coil cleaning in LA typically runs $180 – $340, depending on access and how far the buildup has gone.
Evaporator Coil and Drain Pan Work
The coil and the drain pan beneath it collect water through every cooling cycle. In LA’s older home stock, especially the 1940s and 50s stucco bungalows in El Sereno and Lincoln Heights, we regularly find drain pans rusted through or clogged with a sludge that backs up into the air handler closet. We clean the coil, clear the drain line, and treat the pan, then run the system to confirm it drains properly before we pack up.
When LA Homeowners Should Schedule This
If your AC has been running for two or three LA summers without a coil cleaning, it’s due. If you’ve done remodeling work, even just drywall sanding in one room, that dust gets pulled straight onto the coil. A coated coil can cut cooling capacity by a measurable margin, and in a heat wave, that’s the difference between a comfortable house and a brutal August. We include coil cleaning as part of every full HVAC cleaning job.
AC Cleaning in Los Angeles
AC cleaning in Los Angeles goes beyond the coil. The blower motor, blower wheel, air handler cabinet, and condenser unit all collect the same fine dust that settles on every surface in this city. When we clean an AC system in Los Angeles, we’re cleaning the complete air path, from return grille to supply register. A full AC cleaning for a typical LA home runs $350 – $600, and that price is locked in writing before we remove a single panel.
Blower Motor and Wheel
The blower wheel is the component most LA homeowners never see. It spins constantly while the system runs, and every blade collects a coating of dust that throws the wheel out of balance and reduces airflow. In homes near the 101 or 405, the accumulation is worse because the particulate load in the air is higher. We pull the blower assembly, clean the wheel blade by blade when needed, and vacuum the motor housing with a HEPA-rated Nikro unit that captures what it extracts, rather than recirculating it into your living room.
Condenser Cleaning
The condenser sits outside, and in Los Angeles it deals with dust, pollen, and the fine grit that blows in from the hills during Santa Ana events. In neighborhoods like Atwater Village and Eagle Rock, where mature trees drop leaves and seed pods year-round, the condenser fins get clogged fast. We clean the coils, clear the debris, and check the refrigerant lines, all as part of the flat system price.
Trusted Brands We Service in Los Angeles
We work on systems from every major manufacturer you’ll find in Los Angeles homes: Carrier, Trane, Lennox, Rheem, Goodman, and York, plus older units that predate the current generation of equipment. Our trucks carry Guardsman filtration products so we can offer a filter upgrade on the spot when we see a system running undersized filters. And with an Abatement Technologies containment setup, we can clean systems in tight LA utility closets without pulling dust into the hallway. We don’t have to wait on parts for most jobs because our local stock covers the common replacement components.
Common HVAC Cleaning Problems We See in Los Angeles Homes
- Decade of dust with little heating use. Most Los Angeles homes run heat only a handful of weeks per year, so the filter cadence that works in colder climates never gets established here. The air handler and return ducts quietly collect years of dust and pet dander without the forced-air cycles that would push a filter change.
- Inaccessible duct runs in older and hillside homes. Post-and-beam construction on hillside lots and crawl spaces under 1920s bungalows often mean ductwork snakes through places no human can comfortably reach. Before we quote a flat price, we run a camera inspection to see what we’re actually dealing with.
- Crumbling duct insulation. In pre-1960 homes across Highland Park, Glassell Park, and Echo Park, the original ductwork is often wrapped in asphalt-impregnated insulation that’s now falling apart. We pulled a return grille in a bungalow off Aldama Street and found exactly that, plus a lint pathway feeding straight into the air handler closet.
- Renovation dust inside the system. LA’s constant flip-and-remodel cycle means many systems have been running through drywall dust, flooring debris, and paint overspray from a contractor’s work. That fine dust bypasses the filter and lands on the coil and blower wheel, where it stays until someone cleans it properly.
Pricing for HVAC Cleaning in Los Angeles, CA
We give one flat price per system, agreed to in writing before we touch anything. For a standard single-family home in Los Angeles, a full HVAC cleaning typically runs $400 – $650. A standalone coil cleaning runs $180 – $340. A standalone blower cleaning runs $150 – $250. What changes the number is access: crawl space ducts in a 1930s Mount Washington home cost more to clean than attic runs in a 1960s Sherman Oaks rancher. We’ll tell you the exact price after a camera inspection, and it won’t change. Call (737) 727-2314 to schedule a free estimate.

FAQs About HVAC Cleaning in Los Angeles
Honestly? Every three to five years for most LA homes, with some exceptions. If you have pets, run your AC hard every summer, or live near a freeway corridor like the 110 or 101, every three years makes sense. If you’re in a newer home with good filtration and no pets, five years is reasonable. A lot of companies will tell you annually because that’s how they make revenue. We’ll tell you when it’s genuinely needed and when it can wait, because the 365-Day Done Right Promise means we’re accountable for the work, not for inventing reasons to come back. Call (737) 727-2314 and we’ll give you a straight answer about your system.
One flat price per system, agreed to in writing before work starts. We don’t charge per vent, and we never will. Per-vent pricing creates an incentive to rush through supply and return ducts and skip the air handler and blower motor, which is where the real problems live. Our price covers the complete system: air handler, blower, coil, condenser, and every accessible duct run. The number you approve is the number on the invoice. If you want an exact quote for your home, call (737) 727-2314.
It starts with a camera inspection so we can see the condition of the ducts, the coil, and the blower before we quote. Then we contain the work area, connect a HEPA vacuum in negative pressure so loosened debris goes into the unit and not into your living room, and use agitation tools to break the dust free from the duct walls. We clean the air handler, blower wheel, evaporator coil, and condenser. The job ends with before-and-after photos of your own system, which you receive before we leave. That’s The Relay Standard, and it’s part of every booking. Call (737) 727-2314 to schedule.
We typically schedule within a few days, but we don’t promise same-day service because a proper HVAC cleaning requires a camera inspection first and the right equipment staged for your specific system. Rushing the booking to hit a same-day window in Los Angeles traffic means cutting corners we’re not willing to cut. Call (737) 727-2314 and a live person will give you the soonest honest arrival window, trackable via The Relay Standard link you’ll receive when we’re dispatched.
The dryer vent is separate from your HVAC system, but in LA homes where the dryer sits near the air handler, lint from the dryer vent often gets pulled into the return air stream and ends up coating the blower and coil. When we’re cleaning your HVAC system and we spot that, we’ll tell you. We can clean the dryer vent on the same visit if you want, at a separate flat price agreed before we start. It’s the same transparency we apply to every service. Call (737) 727-2314 to add it or ask for a quote.
