Professional Ductwork Repair & Installation in Hialeah & Miami-Dade County
Many homeowners in Hialeah and Miami mistakenly blame their AC compressor when their home feels warm or humid, when the real culprit is deteriorating attic ductwork. In South Florida's extreme attic temperatures—frequently exceeding 130 degrees in July and August—a leak in your return duct draws scorching, humid attic air directly into your air handler. Comfort SOS Corporation provides expert duct repair, custom sheet metal fabrication, and professional air sealing.
Common Signs You Need Ductwork Repair & Installation
If your system exhibits any of the following warning signs, continuing to operate it in Florida heat can cause severe secondary equipment damage:
What's Included in Our Ductwork Repair & Installation Deliverables
When you hire Comfort SOS Corporation, you receive a full-service, code-compliant execution. Every visit includes the following verified deliverables:
Eliminating Attic Air Infiltration with UL-181 Mastic
Standard cloth duct tape degrades within a few years when exposed to intense attic heat. We use commercial-grade fiberglass mesh tape and UL-181 compliant mastic paste to create airtight seals around all supply and return plenums, take-offs, and ceiling boots.
Solving Return Air Starvation in Older Homes
Many older homes in Hialeah, West Little River, and Miami Springs were built with a single central return grille. When bedroom doors are closed, rooms become pressurized, starving the AC of air and causing the blower motor to strain. We install dedicated jump ducts and return registers to restore proper pressure balance.
Custom Sheet Metal Plenums & High-Velocity Airflow
Our technicians fabricate durable galvanized sheet metal transitions and custom distribution boxes that reduce air turbulence, eliminate register whistling, and ensure equal distribution of cool air to every living space.
How Comfort SOS Executes Ductwork Repair & Installation
We adhere to strict ACCA engineering guidelines, Florida mechanical code, and manufacturer specifications on every call.
Duct Static Pressure & Leakage Inspection
We inspect flexible duct runs, rigid sheet metal plenums, and collar connections in the attic using inspection cameras and pressure manometers.
Thermal Loss & Airflow Measurement
Using calibrated anemometer hoods, we measure CFM output at every register to identify starved rooms and balance return-air velocity.
Mastic Sealing & Collar Tightening
We seal duct seams with fiber mesh tape and UL-181 mastic sealant—never relying on gray duct tape that dries and cracks in Florida attic heat.
R-8 Thermal Insulation Upgrades
We re-insulate ductwork to R-8 standards, preventing attic heat transfer and stopping condensation from sweating onto ceiling drywall.
Final Airflow Balance Certification
We re-verify register CFM delivery and check total external static pressure, ensuring your blower motor operates without restriction.
Factors That Determine the Cost of Ductwork Repair & Installation
We do not give blind over-the-phone guesses or publish unrealistic teaser rates. Every home and commercial system in South Florida is unique. Here are the core technical factors that determine the scope and pricing of your service:
- Repair and localized sealing vs. complete whole-home duct replacement
- Duct material: Flexible insulated ductwork vs. custom sheet metal rectangular trunk lines
- Attic accessibility: High-pitch open attics vs. tight, low-clearance crawl spaces in older Hialeah homes
- Number of supply and return runs being replaced or added
