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.
Fast, Reliable HVAC Cleaning Across Highland Beach
Air Duct Cleaning in Highland Beach isn’t a luxury – it’s how you keep a coastal AC system from quietly failing. Most whole-system cleanings on the island run $350 – $650, and a full evaporator coil cleaning with supply and return duct work typically lands between $450 and $800. That price includes a camera inspection before anything gets brushed or vacuumed, because on a barrier island you need to see what salt and humidity have actually done inside the system. We schedule Highland Beach jobs every week and crews arrive with written pricing already prepared. Call (737) 727-2314 and we’ll walk you through what your system needs.
Why Cardinal Air Duct Cleaning Is Highland Beach’s Preferred HVAC Cleaning Company
Highland Beach homeowners call us because we treat the whole air path as one system, not as a five-minute fog-and-go. Our HVAC Cleaning team runs camera inspections on every visit, so we know whether the evaporator coil is carrying microbial film, whether return-side ducts are the actual source of the odor, and whether salt pitting has begun on the fins. Omar Haddad, who leads our crews, insists on source removal before any treatment. That matters here more than inland, because a surface fog over a biofilm-laden coil just grows back in weeks. You get before-and-after photos of your own ductwork, a live trackable arrival window through The Relay Standard, and a written price before a single access panel is opened.
We’re part of the Relay Home Co. family, founded in 2005, and every booking carries the 365-Day Done Right Promise: if the work isn’t right within a full year, we return and correct it at no charge. No fine print, no exclusion for coastal homes. Technicians are background-checked, arrive in uniform, and operate professional-grade Nikro HEPA vacuums and Abatement Technologies containment units, so the debris we pull from your ductwork doesn’t get blown back through a French balcony screen.
Evaporator Coil Cleaning in Highland Beach
Evaporator coil cleaning in Highland Beach is the single most important HVAC service for this zip code, because the coil sits on the wet side of the system and acts as a condensation collector in air that never really dries out. Salt carried inland from the Atlantic accelerates pitting on aluminum fins, and that rough surface gives microbial film something to grip. A coil that hasn’t been cleaned in two years on a condo near the Intracoastal is usually carrying a gray, slimy film by month eight. Most coil cleanings here run $250 – $500 depending on access and whether we pull the coil or clean it in place.
What the Work Actually Involves
We isolate the air handler, remove the access panel, and photograph the coil before touching it. Then we apply a self-rinsing foaming cleaner, let it lift the biofilm, and rinse toward the drain pan. If the coil is downstream of a return-side problem, we flag that instead of just wiping the surface and calling it done.
When a Coil Needs This Service
You’ll notice it as a musty odor that starts when the compressor kicks on, or as an AC that runs longer to hold the same temperature. In Highland Beach, we also recommend coil cleaning before you close up for the summer or before peak season, because a coil left wet and dark for four months grows more than one that cycles daily.
AC Duct Cleaning in Highland Beach
AC duct cleaning in Highland Beach means getting supply and return sides equally clean, which is where cheap quotes genuinely fail. The return side pulls air from your living space through a dark, humid channel before it ever reaches the coil. If that channel has been skipped, the freshly cleaned coil just gets re-seeded within days. A full system clean with camera inspection here runs $450 – $800 for an average two-bedroom condo; larger townhomes with long supply runs sit at the top of that range.
Source Removal, Not Fogging
We use agitation tools to mechanically detach debris from duct walls, then run a HEPA-rated negative-pressure vacuum so the loosened material goes straight into containment. Negative-pressure extraction means the debris leaves the duct, not your living room. After the pass, we camera the supply and return sides again and show you the before-and-after images.
Why Seasonal Homes Need It More Often
Highland Beach has an unusually high share of seasonal residences that sit shuttered for three to six months. Stagnant, humid air inside ductwork during those months is exactly where microbial growth concentrates. When a snowbird returns in November and fires the AC, what they smell is that stagnant growth being blown into the unit. Cleaning before an extended shutdown, or immediately after one, is the pattern we recommend most.
Trusted Brands We Service in Highland Beach
Our crews service the major HVAC brands you already find in Highland Beach buildings: Carrier, Trane, Lennox, Rheem, Goodman, and Bryant, plus mini-split systems from Mitsubishi, Daikin, and Fujitsu. We stock common coil cleaners, pan treatments, and Aprilaire filtration media for fast turnaround when you need a filter upgrade. We also install Honeywell and Aprilaire filtration products if a cleaning reveals that your return side needs better particulate capture. Highland Beach residents don’t have to wait for an inland shop to source a part. We bring what’s likely needed on the truck.
Common HVAC Cleaning Problems We See in Highland Beach Homes
- Return-side biofilm on A1A condos: The return duct behind the wall is skipped on most cheap cleanings. We camera it, and in a coastal condo it’s almost always coated.
- Salt-pitted evaporator fins: Airborne salt corrodes aluminum coil fins, and that rough surface traps dirt and microbial film faster than a smooth inland coil. Coil cleaning reveals whether pitting has gone deep enough to require service.
- Sand and shell dust in supply ducts: Walk-off from the beach finds its way into floor returns, and fine shell particulate is abrasive on blower motor bearings over time. We see it in homes near Spanish River Park and along Bel Lido Drive.
- Stale odor on first AC cycle: Seasonal homeowners near the Intracoastal call us for this every November. The smell is microbial film that built up in stagnant ductwork during the closed-up months.

FAQs About HVAC Cleaning in Highland Beach
Yes. Highland Beach sits on a barrier island between the Intracoastal Waterway and the Atlantic, so duct runs here pull air that is consistently high in moisture and salt. That combination grows microbial film faster and corrodes coil fins sooner than inland Palm Beach County homes experience. A cleaning here needs to address salt pitting and biofilm, not just dust. Call (737) 727-2314 if your system hasn’t been inspected in over a year.
A real coil cleaning physically removes the biofilm from the coil surface using a foaming cleaner, agitation, and rinse. A spray-on sanitiser only treats the surface layer; it doesn’t remove the organic buildup the microbes anchor into, so the film returns within weeks in Highland Beach humidity. We do source removal, and we camera the coil before and after to show you the difference.
They sit closed for months. When air isn’t moving through the system, moisture in the ductwork doesn’t dry out, and that’s the exact condition for microbial growth to concentrate. Seasonal homes here should have a camera inspection before a long shutdown or right after reopening, and a full duct cleaning is generally recommended if the return side shows visible film.
Yes, and in Highland Beach we recommend it. Skipping the return side, which is harder to reach, means the freshly cleaned coil gets re-seeded with whatever was living in the return duct. We clean supply and return as a balanced system, and the before-and-after photos include both sides so you can see the full job.
We run a camera through the supply and return ductwork after the cleaning and show you the before-and-after images side by side on the spot. That’s the Relay Standard at work. If a section doesn’t look clean, we redo it right then. And if anything isn’t right within 365 days, we come back at no charge under the 365-Day Done Right Promise. Call (737) 727-2314 to schedule a free estimate.
We pulled a return-side run at a condo off A1A near Spanish River Park where the evaporator coil and blower motor were downstream of the wet side. The coil and the first six feet of supply ducts carried visible microbial film and salt-driven pitting. After a camera inspection and negative pressure setup, we used agitation tools to break the growth loose, then HEPA filtration to capture it. The homeowner told us the stale smell was gone on the very next cycle. That’s the standard we hold for every job in Highland Beach.
