Duct Cleaning Cost - What It Actually Costs, Quoted Free

How Much Does Duct Cleaning Cost in Fort Lauderdale?

Duct cleaning in Fort Lauderdale typically costs between $350 and $650 for a full-system cleaning of a standard single-family home in 2026. Smaller condos and apartments in neighborhoods like Victoria Park or Flagler Village run closer to $250 – $400, while larger two-story homes in Rio Vista or Coral Ridge with multiple HVAC units can push past $800.

Duct Cleaning Cost Breakdown (2026)

Here’s what you can expect to pay for duct cleaning in the Fort Lauderdale market this year. These are the numbers we see on service calls across Broward County, from Lauderdale-by-the-Sea west to Plantation.

Service Item	Typical Cost Range
Basic duct cleaning (up to 10 vents)	$350 – $450
Full-system cleaning (10 – 16 vents)	$450 – $650
Large home (16+ vents, multiple return lines)	$650 – $900
Per additional vent (beyond 16)	$25 – $40 each
Sanitizing / antimicrobial fogging	$75 – $150
Dryer vent cleaning (add-on)	$75 – $120
Mold treatment in ductwork	$150 – $500
AC coil cleaning (often done alongside duct work)	$100 – $250

The single biggest driver of price is the number of supply and return vents in the home. A 1950s ranch in Wilton Manors with six vents is a straightforward job. A newer construction in Parkland with zoned cooling, two air handlers, and eighteen vents takes longer and costs more. That’s not a markup game, it’s just labor and time.

Fort Lauderdale’s climate plays a role here too. Coastal air carries salt and moisture, which means the dust and debris inside ducts tends to be stickier and harder to extract than the dry particulate you find in, say, Phoenix or Denver. Our technicians routinely deal with condensation-related buildup in humid attic duct runs, which adds time to the job compared to dryer regions.

What Affects Duct Cleaning Pricing in Fort Lauderdale

• Number of vents and return lines: Most Fort Lauderdale homes built before 1980 have 8 – 10 vents. Newer builds in developments around Davie or Weston often have 14 or more. Every vent adds time.
• Accessibility of the ductwork: Crawl spaces in older East Fort Lauderdale neighborhoods and tight attic clearances in mid-century homes can slow the job down. If the ducts are hard to reach, the labor hours go up.
• Condition of the system: Black sooty buildup, visible mold growth, or evidence of rodents pushing through flex duct in attics means more than a basic vacuum pass. Remediation work is priced separately and can add meaningfully to the total.
• Number of HVAC units: A two-story home in Harbor Beach with separate systems for upstairs and downstairs is essentially two duct-cleaning jobs. Expect to pay on the higher end of the range.
• Add-on services: Sanitizing treatments, dryer vent cleaning, and AC coil cleaning are common add-ons in this market. Each one adds $75 – $250 depending on scope.
• Seasonal demand: Fort Lauderdale’s worst allergy months (March – May) and the lead-up to summer AC season see higher call volume. Scheduling in the fall or winter months often means faster availability, not necessarily lower prices, but you won’t wait as long for an appointment.

How Often Should You Clean Ducts in Fort Lauderdale?

The short answer: every 3 – 5 years for most single-family homes in this climate. That’s tighter than the national average recommendation of every 5 – 7 years, and the reason is simple: South Florida’s humidity encourages mold, mildew, and dust-clot formation inside ductwork faster than drier regions. If you run your AC nine or ten months out of the year (which most Fort Lauderdale homeowners do), you’re moving air through those ducts constantly.

Some situations warrant more frequent cleaning:

• Household members with asthma, allergies, or respiratory conditions
• Homes with shedding pets (two or more dogs or cats)
• Recent renovation or construction work that generated drywall dust
• Visible mold growth near vents or a persistent musty smell when the AC kicks on
• Rodent activity in the attic or signs of droppings near vent openings

If you’re not sure when your ducts were last cleaned, a visual inspection is the place to start. Pull a vent cover off and look inside with a flashlight. If you see accumulated gray-brown coating on the duct walls, it’s worth booking a professional assessment. Dalton Heating & Air includes a duct inspection as part of any service call, and our technicians will show you what they see before recommending work.

What’s Included in a Professional Duct Cleaning?

Not all duct cleaning jobs are equal, and the price on the invoice doesn’t always tell you what was actually done. Here’s what a proper full-system cleaning should include, and what Dalton Heating & Air performs on every duct job in Fort Lauderdale.

Supply and Return Ducts

Both sides of the system get cleaned. Some contractors only do the supply side because it’s easier to access. Dirty returns are just as important, they pull air from your living spaces back to the air handler, so whatever is in those return lines is cycling through your home continuously.

Vent Covers and Registers

Every register gets removed, cleaned, and reinstalled. The visible part of the vent is often the filthiest because it catches dust and grime from the room side.

The Air Handler and Blower

This is the component that pushes conditioned air through the ducts. If the blower wheel and evaporator coil are caked with debris, cleaning the ductwork alone is like washing the pipes but ignoring the pump. Our technicians inspect and clean the air handler as part of the job.

Plenum and Transition Areas

The plenum is the box where duct lines meet the HVAC unit. This junction point gathers the heaviest debris in the system, and it’s where mold problems in Fort Lauderdale homes most often start because of condensation.

The Return Air Drop

The large duct that feeds air back into the unit. In homes with floor returns, this section collects dust, pet hair, and sometimes small objects. We’ve pulled out everything from kids’ toys to six inches of accumulated dust in return drops in older Lauderdale homes.

How to Save on Duct Cleaning

Duct cleaning is not a place to hunt for the lowest bid. A $99 whole-house special almost always means a quick vacuum pass on the supply vents and nothing else. That said, there are legitimate ways to keep the cost down without cutting corners:

• Bundle with HVAC maintenance: If you’re already booking a tune-up or AC repair, ask about combining duct cleaning into the same visit. It reduces trip charges and scheduling overhead.
• Clean during off-peak months: Fort Lauderdale HVAC companies are busiest from April through August. Scheduling duct work between October and February often means faster scheduling and sometimes seasonal pricing.
• Change your filters regularly: A clean filter catches particulates before they enter the duct system. Homes with pets or high foot traffic should replace 1-inch filters every 30 – 60 days, not 90.
• Address issues early: If you smell something musty when the AC runs, get it checked now. Mold remediation on a small section of ductwork costs a fraction of what full-system mold treatment does once it spreads.
• Get a written estimate before you commit: At Dalton Heating & Air, the price goes in writing before any work starts. No exceptions. That means you know the exact number, the scope, and what’s included. Call (754) 354-6972 for a free estimate, and you’ll get the same treatment.

Signs Your Ducts Need Cleaning Now

Some Fort Lauderdale homeowners wait until the problem is visible. Here are the signals that mean you should book a duct cleaning sooner rather than later:

• Dust accumulating on furniture within days of cleaning: This usually means the duct system is pushing particulate back into your living spaces every time the blower runs.
• Musty or stale odor when the AC cycles on: In humid climates like ours, this is a warning sign for mold or mildew in the ductwork or at the evaporator coil.
• Vents with visible dust or dark staining around the edges: Take off a vent cover and look. If you see gray or black coating on the inside walls of the duct, it’s time.
• Uneven cooling between rooms: A clogged trunk line or collapsed flex duct restricts airflow and creates hot spots. Duct cleaning and inspection can identify these restrictions.
• Higher electric bills without a change in usage: Restricted airflow makes the blower work harder and the system run longer to reach temperature.
• Evidence of rodents or insects in the attic: Pest activity in ductwork is a health issue. Droppings, nesting material, and carcasses need professional removal and sanitizing.

The Fort Lauderdale Climate Factor

Ductwork behaves differently in South Florida than it does in most of the country, and any honest pricing guide has to account for it. Fort Lauderdale’s average humidity hovers around 70 – 75% for most of the year. That moisture finds its way into attic-mounted duct runs, especially older sheet metal ducts with poor insulation. Condensation forms on the outside of cold ducts, and over time that moisture attracts dust and creates conditions where biological growth takes hold.

Most homes here built before 1990 use flex duct in the attic. Flex duct is a plastic liner wrapped in fiberglass insulation with a foil outer jacket. It’s effective but vulnerable: when the outer jacket tears (from heat, age, or rodent activity), moisture gets into the insulation layer and the duct loses its thermal integrity. We see this constantly in older neighborhoods like Sailboat Bend, Progresso Village, and Middle River Terrace. Part of a proper duct cleaning here is inspecting the integrity of the ducts themselves, because cleaning a compromised duct is a temporary fix.

Salt air is another consideration for homes east of Federal Highway. The corrosion on outdoor AC units is obvious, but salt particulate also enters homes through open windows and doors and settles inside duct runs. It doesn’t create the health concerns that mold does, but it contributes to faster buildup.

Duct Cleaning vs. Duct Repair: Knowing the Difference

A cleaning job clears accumulated debris from inside the ducts. A repair job addresses the physical condition of the ductwork itself: holes, tears, collapsed sections, disconnected joints, or failed connections at the plenum. Homeowners sometimes call expecting a cleaning and discover they need both.

In Fort Lauderdale’s humid attics, duct deterioration is common. Flex duct failure happens within 15 – 20 years in this climate. Sheet metal ductwork lasts longer but needs inspection at the seams and joints. If a cleaning reveals a torn duct or a disconnected register boot, the fix is separate from the cleaning scope. Here are the typical repair costs you might encounter in this market:

• Replacing a single flex duct run (10 – 15 feet): $250 – $450
• Sealing leaks at plenum connections with mastic: $50 – $150 per connection
• Replacing a damaged vent boot: $75 – $150 each
• Re-insulating a section of duct: $150 – $300 per section

The important thing is to know which problem you’re dealing with before you spend money on a cleaning. A thorough inspection answers that question. At Dalton Heating & Air, our technicians photograph the ductwork during inspection and show you exactly what state it’s in. If a cleaning is what you need, that’s what we quote. If there’s damage that needs repair, you’ll see it with your own eyes.

Our Duct Cleaning Process

Here’s the step-by-step of a Dalton Heating & Air duct cleaning in Fort Lauderdale. It’s the same process whether you’re in a $400,000 condo in North Andrews Gardens or a $3 million home on Las Olas Isles.

1. Inspection and written estimate: The technician examines the supply and return sides, checks the air handler and plenum, removes a few vent covers to assess buildup, and then presents a written price. If the scope changes during the job (unexpected mold, damaged duct discovered), you get a revised number in writing before we proceed. We never add work without your approval.
2. Protect the work area: Drop cloths and shoe covers go down over flooring and furniture near the vent openings being serviced. The cleaning process stirs up dust; we keep it contained.
3. Connect the negative-air extraction system: A high-powered vacuum unit uses negative pressure to draw loosened debris out of the duct system and into a sealed collection system. This is the industry-standard approach used by reputable contractors, not a shop vac stuffed into a vent.
4. Agitate the duct interiors: Rotating brushes and compressed air whip through each duct run to dislodge caked dust, debris, and biological growth. This mechanical agitation is what separates a real cleaning from a superficial pass.
5. Clean the registers and vent covers: Every register gets hand-cleaned and reinstalled. The technician checks for damaged vents and reports anything that needs replacement.
6. Inspect and clean the air handler components: The blower wheel, evaporator coil, and housing get inspected and cleaned if needed. This step matters for airflow and system efficiency.
7. Sanitizing treatment (optional): If you opt for antimicrobial fogging, it’s applied after cleaning so the treatment reaches clean duct surfaces. This is particularly useful in homes where mold was present.
8. Final walkthrough and verification: The technician shows you the before and after photos, reviews what was done, and answers any questions. You get a written summary of the work and the guarantee that applies to the job.

FAQs – Duct Cleaning Cost

How much does duct cleaning cost for a condo in Fort Lauderdale?

Expect to pay $250 – $400 for a condo in Fort Lauderdale, depending on square footage and the number of vents. Condos have shorter duct runs and fewer supply registers than single-family homes, which reduces labor time. High-rise units along the Galt Ocean Mile or in downtown high-rises may have building restrictions on certain cleaning methods; we coordinate with building management when needed. Call (754) 354-6972 for an exact quote, estimates are free.

Is duct cleaning worth the cost?

For most Fort Lauderdale homes, yes. At $350 – $650 every three to five years, it works out to roughly $120 – $200 per year. The main benefits are better indoor air quality for allergy sufferers, reduced dust buildup on furniture, and improved HVAC airflow that can extend equipment life. In homes with visible mold, ongoing respiratory issues, or heavy pet dander, the case is stronger. In homes with minimal dust, no pets, and a relatively new HVAC system, you might stretch the interval to every five years.

How much does mold removal from ducts cost in Fort Lauderdale?

Mold treatment in ductwork runs $150 – $500 on top of the standard cleaning price, depending on how widespread the growth is. Small contained patches near the evaporator coil cost less; full-system contamination throughout the trunk lines and branch ducts costs more. South Florida’s humidity makes mold a common problem, and proper treatment involves not just killing the mold but addressing the moisture source so it doesn’t return. If you suspect mold in your ducts, call us at (754) 354-6972 for an inspection before booking anything.

Can you clean ducts the same day?

Same-day duct cleaning in Fort Lauderdale is available in many cases, especially during fall and winter months when HVAC demand is lower. A standard full-system cleaning takes 3 – 5 hours. During peak season (April – August), same-day slots fill fast, but we answer the phone 24/7 and keep a real person on the line who can check availability immediately. Call (754) 354-6972 and we’ll tell you honestly whether we can get to you today.

Is it cheaper to clean ducts myself or hire a professional?

DIY duct cleaning is cheaper in the narrow sense, but the results don’t match professional equipment. Consumer-grade vacuums don’t create enough negative pressure to pull debris from the full duct run. You can clean visible register openings and change your filters, but you can’t reach the trunk lines, plenum, or air handler without professional tools. Given that real duct cleaning equipment costs several thousand dollars, the $350 – $650 professional service is the practical route for most homeowners.

How much is dryer vent cleaning in Fort Lauderdale?

Dryer vent cleaning runs $75 – $120 as a standalone service or $50 – $75 when bundled with a full duct cleaning. Lint-choked dryer vents are a fire hazard, and they also make your dryer work harder. Homes with longer vent runs, like those with laundry rooms in the center of the house, benefit most from professional cleaning because the lint builds up in the middle section that’s hardest to reach.

Does Dalton Heating & Air give free duct cleaning estimates?

Yes. Estimates are free, always in writing, and they include the full scope of work. The price you’re quoted is the price you pay, with no add-ons invented at the door. If anything changes during the job, you get a revised written number and the option to decline that additional work. Call (754) 354-6972 to schedule.
