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 Coral Gables’s Preferred HVAC Cleaning Company
Coral Gables homeowners deal with a specific kind of ductwork challenge: the city’s strict building envelope means return-air pathways usually run through finished interior spaces, not the open attic chases you find in most of South Florida. That changes how a cleaning crew works, where they place equipment, and how carefully they contain dust. Our technicians arrive knowing this. Omar Haddad, who leads our Coral Gables team, trains every technician on interior-chase containment before they touch a job in this city.
We answer calls with a live person around the clock. When a Coral Gables customer books, they get The Relay Standard: a live arrival window you can track from your phone, before-and-after photo documentation, and a digital invoice payable by link. That’s the same standard for every booking, regardless of crew or day.
Our Coral Gables customers tend to ask the same questions before booking: Will the price change once the technician sees the ducts? It won’t. The written price is the price. Can we trust who’s coming? Every technician is background-checked and uniformed, and you’ll know their name before they ring the bell. Is the work actually done? You’ll see your own ducts in the before-and-after photos, not a stock image.
AC Duct Cleaning in Coral Gables
AC Duct Cleaning in Coral Gables means restoring airflow through the supply and return ducts that push cooled air through your home. In this city, where most homes route those ducts through soffits, closets, and interior chases instead of open attic space, the job requires careful containment and camera inspection. A full AC duct cleaning in Coral Gables runs $425 – $685 for a typical home, and includes cleaning the supply ducts, return ducts, air handler, and blower assembly.
When your AC runs nearly year-round in Coral Gables’s subtropical climate, the system moves a constant stream of air through those tight passages. Over time, dust, pet hair, and construction debris settle inside. You’ll notice it first as weak airflow in rooms farthest from the air handler, or as a fine layer of dust returning to furniture a day after cleaning.
Source-Removal Cleaning, Not Just Register Poking
Some Coral Gables contractors run a vacuum hose into each floor register and call it done. That skips the air handler and blower motor, where most debris actually collects in interior-ducted homes. We use negative-pressure extraction with a Nikro HEPA-rated vacuum: the loosened debris goes straight into a sealed vacuum, not back into your living room. Rotobrush agitation tools break material free inside the duct walls, and our camera inspection confirms the job before we pack up.
Coil Treatment and Evaporator Coil Cleaning
Dirty evaporator coils fight your AC system every day. Coral Gables humidity means coils stay damp longer, and damp coils collect dust faster. We clean the evaporator coil and apply a Guardsman coil treatment that slows future buildup. This isn’t an add-on we push; it’s part of a proper full-system cleaning, included in the flat per-system price.
Furnace Cleaning in Coral Gables
Furnace Cleaning doesn’t mean what it means in Minnesota, but it still matters in Coral Gables. Most homes here use a heat pump or an electric air handler for the brief winter cool-down, not a gas furnace. What needs cleaning is the air handler, the blower wheel, and the heat exchanger if you have one. In Coral Gables, we clean the system that pushes warm air during the two or three months you actually run heat, for $425 – $685 as part of the full-system price.
Because Coral Gables homes have return ducts running through closets and interior soffits, dust that settles inside those passageways during the long cooling season gets recirculated when you switch to heat. That’s when homeowners notice a faint burning smell from accumulated dust on the heat strips, or hear the blower working harder than it should.
Blower Cleaning and Air Handler Cleaning
The blower wheel is where dust collects thickest, and it’s the first place airflow suffers. A coated blower wheel spins slower, moves less air, and forces your system to run longer. We remove the blower assembly, clean each blade, and reinstall it. The air handler cabinet gets brushed out and vacuumed with HEPA filtration so nothing escapes back into the room.
Heat Exchanger Cleaning
If your Coral Gables home has a gas furnace or a heat pump with electric heat strips, the heat exchanger needs attention during any Furnace Cleaning. We inspect for cracks and clean the accessible surfaces. Our team does not instruct homeowners to clean this themselves; heat exchanger inspection and service is technician’s work, no exceptions.
Trusted Brands We Service in Coral Gables
Our Coral Gables customers run all the common South Florida brands: Trane, Carrier, Lennox, Rheem, Goodman, and American Standard. We clean the system, not the brand name – the process doesn’t change because the cabinet says Trane. But we do carry common filters, replacement flex duct, and coil treatment supplies so the truck that arrives at your Coral Gables home has what the job needs. When we need a part, we source it locally and return fast. We run Rotobrush brush systems, Nikro HEPA vacuums, and Abatement Technologies containment units on Oak Avenue, Blue Road, and every street in between.
Common HVAC Cleaning Problems We See in Coral Gables Homes
- Collapsed flex duct inside interior soffits. Coral Gables’s 1950s-to-1970s housing stock frequently routes ductwork through narrow interior chases. Flex duct makes a sharp 90-degree turn, kinks, and collapses. Airflow to that room drops to nearly nothing, and only a camera inspection catches it.
- Per-vent cleaning that skips the air handler. We regularly follow contractors who ran a hose into each floor register but never opened the air handler cabinet. In Coral Gables homes with interior return chases, the air handler and blower are where the real debris sits. The register-only job looks fine from the outside and does almost nothing.
- Dust spread during cleaning because of skipped containment. When the return duct runs behind a closet wall rather than through an open attic, a cleaning crew that skips negative-pressure containment will blow dust straight into the bedroom. We use Abatement Technologies containment and HEPA vacuum extraction from start to finish.
- Same-day promises made before checking duct material. A contractor who promises same-day service in Coral Gables hasn’t looked at your duct routing yet. Tight soffit work with collapsed or damaged flex duct often requires a return visit with replacement material. We tell you that upfront, in writing.
Pricing for HVAC Cleaning in Coral Gables, FL
A full-system HVAC Cleaning in Coral Gables runs $425 – $685 for a single-family home up to about 2,500 square feet. That is one flat price per system, and it covers the supply ducts, return ducts, air handler, blower, evaporator coil, and coil treatment. Larger homes with multiple systems pay a per-system price for each system, quoted before work starts.
What changes the price: number of systems, duct accessibility, and whether collapsed flex duct in an interior soffit needs replacing. What does not change the price: once written, the number stays the number. We hand you that written price before a single duct is touched. Call (737) 727-2314 for a free estimate.

FAQs About HVAC Cleaning in Coral Gables
We charge one flat price per system, never per vent. A full-system Coral Gables HVAC cleaning runs $425 – $685 and includes every duct, the air handler, the blower, the evaporator coil, and coil treatment. Per-vent pricing is how contractors bait a low number and then inflate the invoice on arrival. You’ll have our written per-system price before any of our Coral Gables work begins. Call (737) 727-2314 for a quote.
Because Coral Gables ductwork is often routed through tight interior soffits and closet chases, and we won’t quote a time before we know what we’re dealing with. A 1960s Biltmore-area ranch might need a collapsed flex duct replaced, and that means a parts run and a follow-up visit, not a rushed same-day job. We’d rather give you an honest schedule than a promise we can’t keep.
Every four to seven years for most Coral Gables homes. Homes with pets, heavy landscaping debris, recent construction or renovation, or residents with respiratory concerns should lean toward the four-year end. Some homes go longer without real problems. If your system pushes air well and the ducts look clean on camera inspection, we’ll tell you the truth: it doesn’t need cleaning yet.
Yes. Every Coral Gables job includes before-and-after photo documentation of your actual ductwork, sent to your phone as part of The Relay Standard. Not a generic photo of someone else’s house. You’ll see the inside of your own return duct before and after we work, which also gives you proof the job was real.
NADCA is the National Air Duct Cleaners Association. Its standard calls for cleaning the entire HVAC system, including the air handler, blower, and coils, not just the accessible duct runs. In Coral Gables, where interior duct chases make full access harder, we follow NADCA’s source-removal approach with Rotobrush, Nikro HEPA extraction, and camera verification. That’s the difference between a real cleaning and a register vacuum job.
