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 Miami Beach
HVAC cleaning in Miami Beach typically costs $380 – $680 for a full system in a standard condo or single-family home, depending on how many units and how much salt-air buildup has accumulated on the coils and in the duct runs. Most jobs are completed in a single visit, usually 3 – 5 hours. If your AC smells musty when it cycles or your vents are throwing dust onto furniture near Alton Road or along Collins Avenue, the problem is rarely the filter alone. Call (737) 727-2314 and we’ll give you a written price before any work starts.
We work in Miami Beach every week, so we know what coastal air does to a system. Salt-laden moisture moves through the return, hits the evaporator coil, and leaves a biofilm that ordinary duct cleaning won’t touch. Our crews understand the difference between a dirty duct and a fouled coil, and we bring the tools to fix both in the same visit.
Why Cardinal Air Duct Cleaning Is Miami Beach’s Preferred HVAC Cleaning Company
We’re part of the Relay Home Co. family, founded 2005, and every job is held to The Relay Visibility Guarantee.

Omar Haddad leads our team with a simple standard: if the work isn’t right, we return and correct it at no charge within 365 days. That’s the 365-Day Done Right Promise, and it applies to every booking without exception.
Our technicians are background-checked and arrive in uniform, and they carry professional-grade equipment: Nikro HEPA vacuums for negative-pressure extraction, Rotobrush agitation tools for source removal, and Abatement Technologies containment units when a job calls for it. You’ll know the tech’s name before they open the door. No vague estimates, no four-hour arrival windows.
Miami Beach customers call us from South Beach, Mid-Beach, North Beach, Sunset Harbour, and Biscayne Point. We schedule locally, and dispatch runs from our Miami (South FL) office, so response times to Miami Beach neighborhoods are measured in hours, not days. A live person answers calls 24/7. You won’t get a voicemail loop.
AC Cleaning in Miami Beach
AC Cleaning in Miami Beach means cleaning the parts of the cooling system that accelerate wear in salt air: the evaporator coil, blower assembly, drain pan, and the air handler interior. In a beachfront condo, ocean humidity and airborne salt settle on the evaporator coil and in the condensate pan, forming a biofilm that restricts airflow and feeds the musty smell that comes back right after the AC cycles. A proper clean restores airflow, drops humidity at the vents, and stops the short-cycling that drives up electric bills.
What We Clean and Why
We remove the air handler panel, clean the evaporator coil with a non-acidic, aluminum-safe cleaner, clear the condensate drain line, and vacuum the blower motor housing. We don’t just fog the return. If standing condensate is in the return plenum, we extract it and dry the area before reinstalling the panel.
What It Costs Here
A standalone AC cleaning in Miami Beach runs $180 – $320 for the evaporator coil and air handler on a standard condo system. For a larger single-family home with a multi-speed blower and a zoned supply, expect $260 – $420. You’ll have a written price before work begins.
Evaporator Coil Cleaning in Miami Beach
Evaporator Coil Cleaning in Miami Beach is the highest-impact service we perform for coastal units. The evaporator coil sits behind the air handler panel, where cold refrigerant meets warm return air. In this climate, salt-laden moisture collects on the coil fins, corrodes them over time, and becomes a home for microbial growth. Skipping coil cleaning is the most common reason a Miami Beach system “freezes up” or loses cooling by August, even after the ducts were supposedly cleaned.
The Coastal Corrosion Problem
Oceanfront buildings along Collins Avenue and West Avenue see accelerated fin corrosion because salt never really leaves the air. We clean the coil, check the fins for salt pitting, and apply a coil treatment that slows future buildup. We don’t pressure-wash the coil, which can fold the fins and destroy heat transfer.
Coil Treatment and Airflow Verification
After cleaning, we apply an anti-microbial coil treatment (Apair products) and verify airflow across the blower motor. If the blower motor has been starved by a dirty coil, you’ll notice the difference at the registers within a day. Coil cleaning plus treatment runs $160 – $300 in most Miami Beach units.
Trusted Brands We Service in Miami Beach
We service and clean systems built around Honeywell, Aprilaire, Carrier, Trane, Goodman, Rheem, and Lennox. We understand how Miami Beach’s humidity ages each of them. Our techs stock common replacement filters in MERV 8, 11, and 13 ratings, plus Aprilaire filter media for whole-home filtration, so we can usually swap a clogged filter on the spot. If you have a Honeywell UV or ventilation system, we inspect and clean that too. We will not sell you a filter upgrade you don’t need on a system that can’t handle the airflow restriction.
Common HVAC Cleaning Problems We See in Miami Beach Homes
- Coastal biofilm on the evaporator coil. Salt and moisture from the ocean create a biofilm on the coil, which restricts airflow and makes the system work harder. We see this most often in oceanfront condos where windows stay open at night and the AC pulls salt-laden air into the return.
- Wet lint and dust near supply registers. Humidity near Miami Beach keeps duct interiors damp, so dust and lint stick to the supply runs instead of blowing through. This is why a quick Duct Cleaning alone won’t stop the dust; the source is moisture, not just debris.
- Fogging sanitizer covers up mold, it doesn’t remove it. Beachfront units in South Beach and North Beach get “deodorized” with a fogging spray that smells good for a week. It never removes the biofilm or wet lint, so the odor returns. Source removal is the only fix.
- Dirty condenser coil on the balcony or roof. Salt air corrodes condenser fins quickly. We include condenser cleaning during a full system service because a dirty condenser forces the compressor to overheat and shortens the system’s life.
Pricing for HVAC Cleaning in Miami Beach, FL
For a typical Miami Beach condo or small single-family home, a full HVAC cleaning runs $380 – $680. That includes the evaporator coil, blower assembly, drain pan, air handler interior, and both supply and return duct runs. A larger home with multiple air handlers, or a system that hasn’t been opened in years, can land between $700 – $950. A standalone evaporator coil cleaning runs $160 – $300, and a condenser coil cleaning alone is $120 – $220. What affects the price most is access: rooftop condensers, tight utility closets, and long duct runs in older Miami Beach buildings add labor time. You’ll always receive a written price before work starts, and it does not change at the door. Call (737) 727-2314 for a free estimate.

FAQs About HVAC Cleaning in Miami Beach
The most common reason is that the previous cleaning only did the duct runs and never opened the air handler to clean the evaporator coil. If biofilm sits on the coil and standing condensate is in the return plenum, the musty smell returns within days. We clean the entire system: coil, plenum, blower, and ducts. Call (737) 727-2314 for an exact quote.
Most Miami Beach homes should have HVAC cleaning every 2 – 3 years, and oceanfront units every 18 – 24 months. Salt-laden humidity accelerates microbial growth and coil fouling, so the interval is shorter than inland Miami. If you smell musty air or see dust around the registers sooner, don’t wait.
No. A fogging sanitizer treats the air in the ducts but does not remove biofilm, wet lint, or salt fouling. It masks odor for a week or two. Source removal of contaminant, with negative pressure and HEPA filtration, is the only acceptable method. We’ll say so directly and won’t upsell a fogging service as a substitute for cleaning.
For most Miami Beach condos, a MERV 8 or 11 filter works best. MERV 13 filters trap more particles but restrict airflow, and in an already-humid, salt-exposed system that can reduce cooling and freeze the coil. We’ll check your air handler’s static pressure and recommend the highest MERV your system can support without choking airflow. Aprilaire media filters are a good fit for many beachfront units.
It’s usually both, but the coil is the primary culprit. A coil coated with biofilm can’t transfer heat, so the system runs constantly but never cools. That lets dust and lint build up in the damp duct runs. We inspect both in a single visit, with camera evidence of what’s actually inside your system. Call (737) 727-2314 and we’ll show you before-and-after photos of your own ducts and coils.
If your Miami Beach system smells like the beach should, something’s wrong. We’ll find the source and remove it, not cover it up. Our crews know the buildings along Alton Road, the high-rises near Lincoln Road, and the single-family homes in North Beach. We’ll bring the right equipment, hand you a written price, and finish the job with photo proof. Call Cardinal Air Duct Cleaning at (737) 727-2314 today. A live person answers.
