Over time, ducts accumulate dust, pet dander, mold spores, pollen, and other allergens that get recirculated every time your HVAC system runs. Professional duct cleaning removes these airborne contaminants at the source — improving airflow, reducing odors, and delivering cleaner air to every room in your home.

• Pricing starts at: $400

• Time in home: 2 to 4 hours

This service is especially important for Miami homes that run their AC virtually year-round. We recommend duct cleaning every 3–5 years, or sooner if you’ve experienced mold, water damage, or poor indoor air quality concerns.

Paired with our UV lights or air purifiers, a smart thermostat gives you a fully connected system to protect your home’s air quality and your family’s health.

Indoor air quality (IAQ) defines the conditions within a building that impact human health and comfort. In Miami, the combination of high humidity and sealed AC environments often results in poor indoor air quality, which the EPA notes can be significantly more polluted than outdoor air. Regular testing and system maintenance are essential to ensure cleaner air for South Florida residents.

The most common air quality issues we encounter in Miami-Dade County and Broward include mold growth and mold spores (driven by high humidity and moisture), excess pet dander and pollen, dust accumulation from dirty ductwork, high levels of volatile organic compounds from building materials and household products, and carbon monoxide from HVAC systems or appliances. Inadequate ventilation is a major contributing factor in both residential and commercial buildings.

You should schedule an IAQ inspection if you notice persistent dust that returns quickly after cleaning, musty or unexplained odors, visible mold on walls or near vents, worsening allergy or asthma symptoms indoors, or rooms that feel stuffy despite your HVAC system running.

Any recent water damage, flooding, or roof leak is also a strong reason to test for mold and moisture. Our technicians can evaluate your environment and give you accurate, honest results.

Mold releases microscopic mold spores into the air that, when inhaled, can trigger allergic reactions, respiratory irritation, and more serious health impacts with prolonged exposure. South Florida’s warm, humid climate makes homes and buildings especially vulnerable to mold growth in ductwork, walls, and around HVAC equipment. Mold testing is included in our comprehensive IAQ inspection, and we offer targeted treatments and UV purification to neutralise mold at the source.

Absolutely. Your HVAC system is the primary mechanism through which air — and everything in it — circulates through your home. A dirty air filter, contaminated ductwork, or malfunctioning system can actively spread dust, mold spores, bacteria, pet dander, and fine particles throughout your living space. Regular HVAC maintenance, timely filter replacements, and professional duct cleaning are among the most effective steps you can take to protect your indoor air quality.

For most South Florida homes, we recommend an IAQ inspection every one to two years, or whenever you notice warning signs like odors, mold concerns, or worsening allergy symptoms.

Homes with pets, high foot traffic, older ductwork, or recent water damage should be evaluated more frequently. Commercial buildings, schools, and offices may have additional requirements under Florida Department guidelines. Our team can recommend the right inspection schedule for your specific environment.

We offer a free consultation to discuss your concerns and assess what type of inspection or testing is appropriate for your home or business. For most residential inspections in Miami-Dade County and Broward, we provide upfront, fixed pricing with no hidden fees. We also offer 0% interest-free financing for qualifying customers. Call us or book online and we’ll walk you through your options before any work begins.
