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 Alhambra
HVAC cleaning in Alhambra means dealing with a specific problem: the San Gabriel Valley inversion layer holds fine particulate low over the city, and the 10 and 710 freeway corridors add brake dust and diesel soot to the mix. That combination settles into return ducts, coats blower motors, and shortens the life of evaporator coils. A full system cleaning for a typical Alhambra home runs $450 – $850, and the work takes about 3 to 5 hours. We know these houses. We know the ductwork in the 1920s Mission-style bungalows and the 1960s tract homes off Main Street. Call (737) 727-2314 and we’ll give you a written price before anyone touches a vent.
Why Cardinal Air Duct Cleaning Is Alhambra’s Preferred HVAC Cleaning Company
We are part of the Relay Home Co. family, founded in 2005, and every booking comes with The Relay Visibility Guarantee: a live trackable arrival window, before-and-after photos of your actual ducts, and a digital invoice you can pay from your phone. That is not a gimmick. It is the standard we are held to on every job in Alhambra, from the Emery Park tract to the hillside streets off Fremont Avenue.
Omar Haddad runs this operation, and he trains every technician to treat an Alhambra home like it belongs to someone who asks good questions. We do not do per-vent pricing. We do not “find” extra registers once the van is parked. You get a single flat price for the whole system, in writing, before we open the first grille. And if it isn’t done right, we come back and make it right, free, for a full year. That is the 365-Day Done Right Promise, and it covers every booking without exception.
Our techs are background-checked and uniformed. They carry Rotobrush rotary agitation tools, Nikro HEPA-filtered negative air machines, and Abatement Technologies containment units when the job calls for it. When a technician arrives at your home in Alhambra, you’ll already know their name and the exact window they’re arriving in.
Evaporator Coil Cleaning in Alhambra
Evaporator coil cleaning in Alhambra is one of the single highest-impact services we perform, because this city’s airborne dust loads coils fast. The evaporator coil sits inside the air handler and pulls heat out of your air. When it is caked in grey-brown grime, your AC works harder, runs longer, and still leaves rooms warm. In Alhambra’s older homes, where return filtration is often a thin fiberglass panel doing almost nothing, we see coils lose 15 to 25 percent of their efficiency within a few years of neglect.
When Alhambra Homes Need It
If your energy bill climbs through the summer and the supply air feels humid, the coil is likely fouled. Homes near the 10 freeway corridor, from Alhambra Road north to Mission, get a heavier dust load than the foothill streets. We recommend checking coil condition whenever the blower compartment is opened, which is standard on every full system cleaning we do.
What It Costs
Standalone evaporator coil cleaning in Alhambra runs $200 – $400 depending on access. If it is part of a full HVAC cleaning package, it is bundled into the flat system price. We quote one number before we start. It does not move.
AC Duct Cleaning in Alhambra
AC duct cleaning in Alhambra is the core of what we do, and it is more than vacuuming at the register. We pull each supply and return grille, run Rotobrush agitation tools through the full run, and keep the system under negative pressure with a Nikro HEPA unit the entire time. Negative-pressure extraction means the loosened debris goes straight into the vacuum, not back into your living room. In Alhambra’s older tract homes, where ducts are often undersized sheet metal from the original gravity-furnace era, this kind of source removal is the only way to actually clear the pathway.
Why Register-Only Cleaning Fails Here
Register-only cleaning leaves the debris packed in the boot and the return drop. In a 1950s Emery Park rancher, that debris includes decades of plaster dust, pet hair, and the fine particulate that settles out of Alhambra’s inversion-layer air. You pay for a service that does not change the condition of your blower motor or your indoor air.
What It Costs
A full AC duct cleaning in Alhambra runs $450 – $850 for a standard single-system home. Larger homes with multiple returns or long commercial-style runs fall at the upper end. The price is set before work starts. It is one number, and it does not change per vent.
Trusted Brands We Service in Alhambra
We service the equipment found in Alhambra homes without playing favorites. That includes Lennox, Carrier, Rheem, Goodman, Trane, and Bryant air handlers, plus the Aprilaire and Honeywell filtration systems many homeowners have added in recent years. Our trucks are stocked with the consumables and access tools these systems need, and our technicians arrive ready to work on your specific setup, not to upsell you into one we prefer. We also stock Guardsman filtration products for customers who want better capture after their cleaning.
Common HVAC Cleaning Problems We See in Alhambra Homes
- Inversion-layer dust loading: Alhambra sits in the San Gabriel Valley’s temperature-inversion bowl. Fine dust, freeway particulate, and brake-liner material settle into return ducts and coat blower motors faster than in coastal or hill cities. This is the number one reason local blowers fail early.
- Undersized original duct runs: Many homes built between the 1920s and 1960s still have their original gravity-furnace sheet metal. These runs are narrow, unsealed, and unforgiving. Cleaning them properly means working carefully with tools sized for the job, not forcing a one-size-fits-all brush through.
- Fouled blower motors from pet hair and dust: We regularly find blower cages in Alhambra air handlers matted with pet hair that has been circulating for years. A dirty blower moves less air, forces the system to run longer, and shortens motor life. Cleaning it is part of a real system cleaning, not an add-on.
- Coils caked with grime behind thin filters: Older Alhambra homes often run standard one-inch fiberglass filters. These stop almost nothing below 10 microns. The evaporator coil becomes the filter by default, and efficiency drops until the coil is cleaned or the system fails.
Pricing for HVAC Cleaning in Alhambra, CA
A standard HVAC cleaning in Alhambra costs $450 – $850 for one complete system. That is the honest range for source removal under negative pressure, including the supply runs, return drops, blower compartment, and evaporator coil. What moves the number? Square footage, number of returns, access difficulty in older crawlspaces, and whether you want filtration upgrades like a Honeywell media cabinet or Guardsman filter. What does not move the number: how many vents we count. We quote one flat price per system, in writing, before we open a single grille. Call (737) 727-2314 for a free estimate. The number we give you is the number you pay.

FAQs About HVAC Cleaning in Alhambra
By system. One flat price for your entire duct system, written down before we start, and it does not change per vent. If a company prices by the vent, the final number depends on how many registers the tech happens to count once they’re already inside. We quote $450 – $850 for a typical Alhambra home, and that is the number on your invoice. Call (737) 727-2314 for an exact quote on your house.
Every 5 to 7 years for most Alhambra homes, assuming you run a reasonable filter and replace it regularly. If you live within a few blocks of the 10 or 710 corridors, you may need it closer to every 3 to 5 years because the particulate load is heavier. And if you’ve just finished a remodel with drywall sanding, clean sooner. We’ll tell you honestly if your ducts don’t need it yet. That is part of the job.
Yes. Every Cardinal Air Duct Cleaning job includes photo documentation of your actual ducts: the return boot before, the blower compartment before and after, the coil before and after. It is part of The Relay Standard. You see what we saw, and you see what changed. If a company will not show you photos of your own system, ask why.
We clean the evaporator coil as part of the full system cleaning. That means removing the access panel, inspecting the coil, and cleaning it so heat transfer actually works again. A company that cleans only the ducts and skips the coil is leaving the single most important surface in your system untouched. In Alhambra’s dust-heavy air, that surface fouls fast. Call (737) 727-2314 to talk through what your system needs.
Sometimes, but we won’t promise it. HVAC cleaning is a scheduled job. We coat a building in containment and carefully source-remove debris from every run. It is worth doing right, not fast. The teams serving Alhambra are dispatched from our Los Angeles office, and we will give you a live arrival window you can track on your phone. Same day is possible when a slot is open, but no technician is ever rushed to hit a same-day promise.
