Why It Matters
Why South Florida Homes Need AC Coil Cleaning
Your AC system has two coils that are critical to its operation — the evaporator coil inside your air handler and the condenser coil in your outdoor unit. When either coil is coated in dirt, dust, mold, or debris, your system loses the ability to transfer heat efficiently. The result: your AC runs longer, cools less, and fails sooner.
In South Florida's climate — running AC virtually 365 days a year — coil contamination accelerates dramatically compared to seasonal markets. Homeowners commonly see 25–40% efficiency loss from dirty coils, which shows up directly on their FPL bill every month. A system working harder to compensate for dirty coils also puts extreme stress on the compressor — the most expensive component to replace, often costing $1,500–$3,000+.
US DuctMaster offers a completely free inspection so you can see the condition of both coils before any work begins. We document what we find, provide a written estimate, and you decide — zero obligation.

What's Included
Everything Covered in Every AC Coil Job
Every AC coil cleaning covers both coils completely — evaporator and condenser. No upsells, no partial jobs, no surprises.
Evaporator Coil Cleaning
The evaporator coil inside your air handler is cleaned using professional coil-safe chemical treatments and low-pressure rinse to remove accumulated dust, mold, and bio-film. South Florida's humidity accelerates mold growth on evaporator coils dramatically.
Included in every job
Condenser Coil Cleaning
The outdoor condenser coil is cleaned using professional coil cleaners and high-pressure rinse to remove dirt, pollen, salt residue, and debris. Blocked condenser coils are the leading cause of AC system overheating and compressor failure in South Florida.
Included in every job
Drain Pan & Line Inspection
The condensate drain pan and drain line are inspected for standing water, mold, and blockage. A clogged drain line causes water backup, ceiling and wall damage, and mold growth inside the air handler.
Included in every job
Coil Fin Straightening
Bent or crushed coil fins reduce airflow across the coil surface. We inspect fin condition and straighten damaged fins using professional fin combs where needed — restoring maximum efficiency.
Included in every job
System Performance Check
After cleaning, we verify that your system is pulling adequate airflow and both coils are functioning as expected. You get a clear picture of your system's condition and whether additional HVAC service may be warranted.
Included in every job
Written Estimate & Report
Before any work begins you receive a complete written estimate. After the job, a service report documents the condition of both coils, the drain system, and any issues identified.

Our Process
How AC Coil Cleaning Works
01
Free Inspection & System Assessment
Our technician inspects both your evaporator coil and condenser coil at no charge. We assess contamination level, drain pan condition, fin damage, and any visible mold or corrosion, then provide a written estimate before anything is touched.
02
Evaporator Coil Treatment
The indoor air handler is accessed and the evaporator coil is treated with professional-grade, coil-safe chemical cleaner that dissolves bio-film, mold, and compacted dust from coil fins and surfaces.
03
Condenser Coil Cleaning
The outdoor condenser unit is cleaned using coil cleaner and controlled-pressure rinse to remove dirt, pollen, salt deposits, and debris from the exterior fins.
04
Drain Pan & Line Check
The condensate drain pan is inspected for standing water and mold, and the drain line is checked for blockage — one of the most common causes of water damage and indoor mold growth in South Florida homes.
05
Fin Check, Verification & Report
Coil fins are inspected and straightened where needed. The system is powered on and we verify normal operation with improved airflow. A complete service report documents coil condition before and after.

AC was running constantly and my FPL bill was through the roof. US DuctMaster cleaned both coils — within a week my bill dropped noticeably and the system cycles off like it should.

HVAC tech told me I needed a new system. Got a second opinion — US DuctMaster cleaned the coils and the system runs perfectly. Saved thousands. The evaporator coil was completely coated in buildup.

Free inspection showed us exactly what was going on with both coils. The before/after was shocking. House cools faster now and the air smells cleaner.

FAQ
Frequently Asked Questions
How often should South Florida homes get their AC coils cleaned?
Annually — South Florida AC systems run year-round, meaning coils accumulate contamination far faster than in seasonal markets. Miami-Dade, Broward, and Palm Beach homes should treat this as essential annual maintenance. Homes with pets, dusty environments, or older systems may benefit from more frequent cleaning.
What are the warning signs my AC coils need cleaning?
Your AC running constantly without reaching your set temperature, higher-than-normal electric bills, reduced airflow from vents, the system freezing up or icing over, musty or stale odors from vents, and warm air from supply registers. Musty odors specifically are often a sign of mold on the evaporator coil.
What does the free AC coil inspection include?
Our technician inspects both the evaporator coil and the condenser coil at no charge. We assess contamination level, mold presence, fin condition, and the drain pan and drain line. You receive a written estimate before any work begins — with zero obligation to proceed.
What's the difference between evaporator and condenser coil cleaning?
The evaporator coil is inside your air handler — it absorbs heat from indoor air. It accumulates dust, mold, and bio-film. The condenser coil is in the outdoor unit — it releases heat and gets coated in dirt, pollen, grass, and salt air residue. Both must be clean for the system to operate efficiently. We clean both in every service.
Can dirty coils really cause my AC to fail?
Yes — dirty condenser coils are one of the leading causes of compressor failure in South Florida. When the condenser can't release heat efficiently, the compressor runs hotter and under greater load. Over time this causes premature failure. A compressor replacement typically costs $1,500–$3,000+. Annual coil cleaning costs a fraction of that.
