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 Miami
HVAC Cleaning in Miami usually means cleaning the whole air-side system: evaporator coil, blower, air handler, supply and return ducts, and registers. Most standard systems in Miami run $400 – $700, done in one visit with a written price before any work starts. That price covers the entire system, not a per-vent count that climbs once we’re inside. Call (737) 727-2314 and we’ll give you an exact quote over the phone.
We work in Miami every day, from Coral Gables bungalows to Brickell high-rise condos with package units on the roof. Local crews know Miami’s building stock and the way salt air and humidity load up a system faster than you’d expect. You get a live trackable arrival window, before-and-after photos of your own ducts, and a written price before the first panel comes off.

AC Vent Cleaning in Miami
AC Vent Cleaning in Miami means pulling the registers, cleaning the vent openings and the first few feet of branch ducting, and removing the crust of dust, hair, and sometimes mold that builds up where conditioned air meets room air. In Miami’s humidity, that crud gets damp and sticky, so it clings to the register blades and the duct mouth more than it would in a dry climate.
You’ll notice it first as a dark ring around the vent or a puff of dust when the AC kicks on. If you can’t remember the last time the vents were pulled and washed, they need it. A standard AC Vent Cleaning for a typical Miami home runs $150 – $300 depending on the number of registers and whether we’re also cleaning the plenum behind them. That’s a flat price per system, agreed before we start.
Register and grille removal
We pull every register and return grille, wash them with a degreasing solution, and inspect the duct mouth behind each one. In older Miami bungalows, we often find the register screws painted over from years of repainting, so we take our time and don’t strip the holes.
Plenum and supply branch cleaning
Beyond the vent itself, we clean the first few feet of the branch line where debris collects. We use a HEPA-filtered vacuum so loosened dust goes into the machine, not back into your living room.
Furnace Duct Cleaning in Miami
Furnace Duct Cleaning in Miami is less about the furnace itself and more about the full duct system attached to your air handler. Most Miami homes run central AC with electric heat strips or a heat pump, so the “furnace” here is usually the air handler in a closet, attic, or garage. The ductwork still collects the same mix of dust, pet hair, and humidity-driven biological growth.
We clean the supply plenum, return plenum, main trunk lines, and branch runs. If your air handler is in a musty closet like so many older homes in Little Havana and Shenandoah, the return side pulls that damp closet air through the system, and the ducts load up fast. A full Furnace Duct Cleaning for a typical Miami single-system home runs $400 – $700, flat price per system, before-and-after photos included.
Return-side cleaning
The return side is where most of the debris enters. We clean the return plenum, the return trunk, and the filter housing, then we check the filter itself. A clogged return in Miami pulls humidity from wherever it can, which accelerates the growth cycle.
Supply-side cleaning and inspection
We run agitation tools through the supply branch runs while negative pressure holds the system under vacuum. Then we camera-inspect the air handler and coil face, because in Miami’s humidity the real problem often sits past the register, inside the plenum.
Trusted Brands We Service in Miami
We clean and maintain systems from all the major manufacturers, and we stock common parts for Miami customers so turnaround stays fast. Honeywell filtration products, Aprilaire media cabinets, and Nikro HEPA extraction equipment all show up regularly in Miami homes and in our trucks. We service residential and light commercial systems across the city, from high-rise splits in Brickell to single-family package units in Westchester. If your system has an unusual filter size or an older coil configuration, we’ll let you know what needs to be ordered and how long it takes before we touch anything.
Common HVAC Cleaning Problems We See in Miami Homes
- Salt-air corrosion on coil faces and plenums: In Miami-Dade, the combination of salt air and year-round humidity means coil-face debris and plenum rust are bigger problems than the dry dust typical of northern duct systems. The air handler cycles almost every day, so a neglected system loads faster than in cities with a true heating off-season.
- Moldy evaporator surfaces: The evaporator coil runs wet for most of the year in Miami. When dust settles on that wet surface, it creates a substrate for biological growth. That’s the “dirty sock” smell people describe when the AC kicks on.
- Hidden branch runs in older bungalows: Homes in Coconut Grove and Little Havana often have flex joints and branch runs hidden behind walls and in tight attics. Per-vent pricing models fall apart on these homes because the vent count doesn’t reflect the actual ductwork. Flat pricing per system solves that.
- Rooftop package units with hard-to-reach returns: Many Miami condos and some single-family homes run package units on the roof. The return is often a short run, but the unit sits in full sun and salt air, so the coil and blower need more frequent inspection than the ducts themselves.
Pricing for HVAC Cleaning in Miami, FL
A standard HVAC Cleaning in Miami costs $400 – $700 for a typical single-system home. AC Vent Cleaning alone runs $150 – $300. If your home has two systems, which is common in Coral Gables and Pinecrest, expect the price to land at the higher end or require a second system charge applied at the same flat-per-system rate.
We quote one flat price per system before any work starts. That price does not change at the door. We don’t quote by number of vents, because Miami’s older homes have hidden branch runs and flex joints that make per-vent pricing explode mid-job. You get a written quote, a live arrival window, and before-and-after photos of your own ducts. Call (737) 727-2314 for a free estimate.

FAQs About HVAC Cleaning in Miami
Yes. Miami’s year-round cooling season means the air handler cycles almost every day, and the humidity keeps the evaporator coil wet, which accelerates biological growth. In cities with a true heating off-season, the system gets a natural drying period. Miami doesn’t get that. Most Miami homes benefit from HVAC Cleaning every 2 – 3 years, more often if you have pets, live near the water, or smell a musty odor when the AC turns on. Call (737) 727-2314 and we’ll tell you honestly whether your system needs it.
We quote one flat price per system before any work starts. A standard single-system home in Miami runs $400 – $700. That price covers the full duct system, air handler, blower, and coil cleaning. We don’t charge per vent, because Miami’s older homes have hidden branch runs and flex joints that make per-vent pricing unreliable and expensive. The written price you get before work starts is the price you pay at the end.
We start by setting negative pressure with a HEPA-filtered vacuum, then run rotary agitation tools through the supply and return trunk lines and branch runs. We pull and wash every register, clean the plenums, and camera-inspect the air handler and coil face. In Little Havana we cleaned a two-story home near Calle Ocho where the air handler had been pulling supply and return ducts through a musty closet and the registers were caked with black debris. After source removal, the homeowner said the “dirty sock” smell that used to hit when the AC kicked on was gone. Every job includes before-and-after photos of your own ducts.
Often yes, because that smell usually comes from biological growth on the evaporator coil or debris in the plenum. When dust settles on a wet coil in Miami’s humidity, it creates the exact conditions for that musty odor. We clean the coil face, the plenum, and the duct runs, then we camera-inspect to confirm the growth is gone. If the smell persists after cleaning, we’ll tell you what’s causing it and what the next step is. Call (737) 727-2314 for an honest assessment.
No. HVAC Cleaning is a scheduled job, and we don’t rush it. We also don’t promise same-day service without confirming whether the home has a second system or a rooftop package unit, because those change the scope of the negative-pressure setup. We’ll give you the soonest available time slot and a live arrival window you can track from your phone. Same flat pricing, same written guarantee, whether you’re in Hialeah or Key Biscayne.
