Air Duct Sealing Services in Hollywood, FL

Seal Leaks and Maximize HVAC Efficiency

Hollywood’s hot and humid climate puts a strain on your HVAC system. If your ductwork has leaks or gaps, a significant portion of the air moving through the ducts can be lost, forcing your system to run longer and driving up utility costs. Hollywood HVAC Experts specializes in air duct sealing services that improve indoor air quality, lower energy bills and enhance overall comfort. Our expert team inspects and seals your ducts to stop air loss, boost system performance and help your property stay comfortable year‑round.

Why Air Duct Sealing Matters

Even small leaks in your ductwork can allow conditioned air to escape before it reaches your rooms. Sealing your ducts protects your home or business from energy loss and indoor air pollution while improving comfort and airflow throughout your space. Sealed ducts offer several benefits:

Improve indoor air quality

stop dust, pollen, mold spores and other contaminants from entering your ducts and circulating through your property.

Enhance HVAC efficiency

restore proper airflow and reduce system strain to lower your energy consumption and utility bills.

Boost comfort

achieve consistent temperatures throughout your home or business with balanced airflow from room to room.

Extend HVAC system lifespan

reduce wear on motors, fans and coils by eliminating leaks that cause your system to overwork.

Lower energy costs

properly sealed ducts can reduce monthly heating and cooling expenses by a noticeable margin.

Our Air Duct Sealing Process

We follow a detailed process to ensure effective sealing and lasting results:

Complete duct inspection

We assess your ductwork for leaks, loose joints, gaps or damaged insulation, including accessible areas like attics and crawlspaces and hidden sections behind walls or under floors.

Targeted leak sealing

We apply long‑lasting mastic sealant or foil‑backed tape to joints, seams and gaps. For large or hard‑to‑reach duct systems, we also offer the Aeroseal process, which sprays sealant inside the ducts.

Insulation check and repair

We ensure your ducts are properly insulated and replace missing or damaged insulation to prevent heat gain and condensation.

Airflow testing

After sealing, we measure system airflow to confirm improved performance and efficiency. A pressure test may also be performed to ensure all leaks are sealed.

Signs Your Ducts May Need Sealing

Rooms that are too hot or too cold compared to others
Higher energy bills without increased usage
Dust or debris collecting around vents
Weak or inconsistent airflow from registers
Musty or moldy odors when your HVAC system runs

How Much Does Air Duct Sealing Cost?

The cost to seal air ducts varies based on the size of your property, the condition of the ductwork and the number of leaks. Typical prices range from $500 to $4 000, with many homeowners spending around $2 250. Home size is a major factor; sealing costs are roughly $1 per square foot, meaning a 1 500‑square‑foot home might cost $750 to $2 250 and a 3 000‑square‑foot home could cost $1 500 to $4 500. Other factors that influence price include:

Sealing method: manual sealing versus Aeroseal
Duct accessibility: attics, basements and crawlspaces are generally less costly than ducts behind walls or under floors
Extent of leaks: small leaks may cost as little as $50 to seal, while larger gaps increase costs
Inspection and testing: an inspection and pressure test may add $150 to $450 to the total

Though air duct sealing is an investment, it often pays for itself through lower energy bills and improved comfort.
