I had All Thermo perform a comprehensive attic cleaning and replace the AC ductwork. They began by removing all the old insulation, sealing the attic floor to reduce air transfer, disinfecting the entire attic space, then replacing the old ductwork and finally installing chemical-free insulation. This has greatly enhanced our indoor air quality and led to a reduction in our FPL bill. Our home now feels entirely rejuvenated. This is the second time we’ve had All Thermo come help us…we also had them out to our old condo almost 10 years ago. Same staff and same great work. These guys exemplify the difference of hiring a small, family owned company that relies on word of mouth and personal referrals.

All Thermo performed AC ductwork sealing, attic air sealing and added new chemical-free attic insulation to my home. We have noticed our Air Conditioner running a lot less and a reduction in our FPL bill. I’d highly recommend this family owned & operated business!

Hi Jason. Just wanted to let you know… we just got a full months power bill since you installed the insulation and our power consumption went from 1,000 kWh the year prior to 425 kWh this month, with a higher average temperature outside. This is the lowest power bill we’ve had. Amazing result!!! Thank you!

Jason and Christian were excellent to work with. They communicated to me throughout the entire process. A huge plus was both Jason and Christian arrived ON TIME. Their prices are very competitive with other insulation companies. Jason was able to answer all of my questions about the type of insulation they use and expected lifespan. No mess was made at all during installation. You couldn’t even tell they were in my home when they were done. It’s been three days since our house received ten inches of insulation over the existing 3-4 inches. It’s been so nice to come home to a house that has been able to maintain its temperature! Previously our two year old AC could not keep up. It would be set to 75 and it would be 78 in the house during peak hours. Now when I come home it’s 75 degrees inside as it should be. Our AC seems to be running much less. I’m looking forward to hopefully saving some money on my next electric bill.

Buy a house they said... Lord have mercy it has been one thing after another, just when you think your are done, you get a kick in the pants! Dont get me started on the contractors here in Florida with poor response, poor workmanship and poor customer service, are you with me so far? Well the journey begins! Let me set this up for you. I put a new roof on approx. June 2022, hang on, I'm going someplace with this.! I have had 5 roof leaks! Yeah I said it, did I do a review on that company? No but it is coming you can count on it. So I thought putting in insulation in my attic would be good for the house and my AC unit. I called 2 companies-only one returned my call. Why only 2- I read the reviews. I did my research. The question is put the new insulation on top of the old or remove the old and than the new. I went with the latter one. Than I am hearing horror stories of feet, hands coming through the ceiling! I asked this company "does this happen?" Yes they said but not often they are very carful (I heard this before) I HAVE A STOMACHACHE! Well Jason (Scooter) who showed up, was very professional, knew what he was talking about, when I asked questions he explained everything  to me so I understood. Ok I thought this was too easy. Now Christian and the crew showed up (here it is-this is what I was waiting for) Nope Christian was a duplicate of Jason! WAIT WHAT...what is happening here? Work was completed in 2 days ! They cleaned up my garage, and driveway like no one was there! The work was perfect absolutely perfect! Tears of joy ladies and gentleman ! Tears of joy! I want to adopt this entire family! Yes this is a family owed business! Oh Ms Thomas you have a small roof leak! And there it is! Leak number 5. All Thermo & your staff I want to thank you so much for all your hard work, working in the attic with this heat. Are you hiring? Hire Them you WIIL NOT BE SORRY, tell them I sent you!

All Thermo - AC Duct Work, HVAC & Air Ductwork Services

What is AC Duct work or HVAC Ductwork

AC ductwork refers to the system of ducts used in air conditioning and heating systems to distribute conditioned air throughout a building. These ducts are pathways that allow the air to flow from the central HVAC (heating, ventilation, and air conditioning) unit to various rooms and spaces within a home, office, or other types of buildings.

The main components of AC ductwork include:

  1. Supply ducts: These ducts carry conditioned and filtered air from the central air handler or furnace to different rooms and areas. The air is distributed through vents or registers installed on walls, floors, or ceilings.
  2. Return ducts: These ducts are responsible for transporting air back to the central unit for reconditioning. They collect air from various rooms and return it to the HVAC system.
  3. Air vents/registers: These are openings in walls, ceilings, or floors where conditioned air is released into the room. They allow air to enter or exit the duct system.
  4. Plenums: A plenum is a box-like space used to facilitate airflow between the HVAC unit and the ductwork. It acts as a distribution chamber to evenly direct the airflow into the ducts.

AC ductwork can be made from various materials, such as sheet metal, flexible ducts, or fiberglass duct board. The choice of material depends on factors like cost, efficiency, and noise reduction.

Properly designed and installed ductwork is crucial for the efficient operation of an HVAC system. Leaks or poorly insulated ducts can lead to energy wastage, reduced system performance, and decreased indoor air quality. Regular maintenance and periodic cleaning are necessary to keep the ductwork in optimal condition and ensure the delivery of clean, comfortable air throughout the building.

AC Ductwork Services and Replacement

AC Ductwork Replacement, Air Duct Work Repair - All Thermo

AC ductwork replacement involves replacing the existing duct system in an HVAC (heating, ventilation, and air conditioning) system with new ductwork. There are several reasons why ductwork replacement may be necessary:

  1. Age and wear: Ductwork, like any other component of an HVAC system, can degrade over time due to age, wear and tear, and exposure to environmental factors. If the ducts are old, damaged, or showing signs of deterioration, it might be time for a replacement.
  2. Inefficiency: Older ductwork may not be well-insulated or properly sealed, leading to energy losses. Leaks in the ducts can cause conditioned air to escape, resulting in reduced system efficiency and higher energy bills.
  3. Poor indoor air quality: Ducts that are clogged with dust, debris, or mold can contribute to poor indoor air quality. Replacing the ducts can improve air circulation and reduce the presence of allergens and pollutants in the air.
  4. Renovations and remodels: During home renovations or remodeling projects, it might be necessary to replace the existing ductwork to accommodate changes in the layout or design of the building.
  5. System upgrades: When upgrading to a more efficient HVAC system, it is often beneficial to replace the ductwork as well to ensure optimal performance and compatibility.

The process of AC ductwork replacement typically involves the following steps:

  1. Assessment: A professional HVAC technician will inspect the existing ductwork to determine its condition, identify any issues, and assess the specific requirements for replacement.
  2. Design: Based on the assessment and the needs of the building, a new ductwork design is created to ensure proper airflow and distribution of conditioned air.
  3. Removal: The old ductwork is removed carefully to avoid damage to the surrounding areas and other components of the HVAC system.
  4. Installation: The new ductwork is installed following the designed layout, and all connections and joints are sealed properly to prevent leaks.
  5. Testing: The newly installed duct system is thoroughly tested for airflow, pressure, and efficiency to ensure it meets the required standards.
  6. Insulation: If necessary, the new ductwork is insulated to prevent energy losses and maintain temperature consistency.

AC ductwork replacement is a complex task that requires professional expertise and should not be attempted as a DIY project. Hiring a licensed HVAC contractor ensures that the replacement is done correctly, maximizing system performance and energy efficiency.

AC Sealing

All Thermo -Duct Sealing

Duct Sealing

Our AC ductwork sealing services look for rips, holes or tears in your ductwork. That can be easily sealed to increase efficiency and save you money.

For more than 40 years, All Thermo has been a trusted partner in air duct sealing maintenance throughout south Florida. If you need an expert to look at your ductwork, now is the time to give us a call. Every time you operate your home heating and cooling system, you are taking advantage of the air ducts that run throughout your house. This system of ducts carries air to and from your home comfort system and it also includes ducts that carry cooking and dryer fumes and other contaminants away from your home and release them into the outdoor air.

You probably do not spend much time thinking about these ducts because you really never see them. They are tucked inside of walls and beneath floors, out of sight and out of mind. But the condition of these ducts can actually have a pretty significant impact on the environment inside your home. If your ducts are leaking, your home heating and cooling systems will not be able to function as efficiently and your indoor air quality can suffer.

Proper air duct sealing can take care of all of these problems, however. If you are concerned about the state of your ducts or think that you may have leaks in your system, be sure to call All Thermo Acoustics & Insulation. Our technicians provide expert duct sealing services to customers all over south, FL area and we would be glad to help you today.

Where HVAC Duct Work Leaks Come From

But why are your ducts leaking in the first place? Well, there are actually quite a few reasons that may be the case. For instance, you ducts may simply be old. Just like any other piece of equipment in your home, your ducts will not last forever. They are used constantly all year long and that wear and tear can take a significant toll over time.

Also, your ducts are not commonly installed in places with very much insulation or protection from the elements. That means that they will be regularly subjected to extreme hot and cold conditions throughout the year. This type of extreme weather can really take its toll on your ducts and cause plenty of leaks and cracks to develop.

Improper installation is another possible cause of leaky ducts, and if you do not know when your ducts were put in or who did the installation, this is something you may suspect. In extreme cases, improperly installed ducts must be completely replaced. Often though, proper sealing can take care of the problem and get your ducts into good working order.

Benefits of AC Ductwork Sealing

Air Duct Sealing

Taking the time to have your ducts sealed properly is well worth the investment for a number of reasons. First of all, properly sealed air ducts will make your entire heating and cooling system work better and more efficiently. That means lower monthly energy bills for you and a more comfortable house overall.

Also, you will benefit from improved indoor air quality once your ducts have been properly sealed. All of the contaminants that can leak in through the cracks will be blocked out, and you can breathe a little easier inside knowing that your indoor air is clean and contaminant free.

Sweating AC Ducts or Condensation on AC Vents

Sweating AC

Sweating AC ducts occur when warm, moist air comes into contact with cold duct surfaces, causing condensation to form on the ductwork. This issue is more common in hot and humid climates or during periods of high indoor humidity. It can lead to problems such as water damage, mold growth, reduced efficiency, and even air quality issues. There are a few common reasons why AC ducts sweat:

  1. Inadequate insulation: Ducts that lack proper insulation can allow the cold air inside them to come into contact with the warm, humid air outside, leading to condensation. Properly insulating the ductwork can prevent this problem.
  2. Air leaks: Leaky ducts can draw in warm, humid air from surrounding spaces, causing condensation when it comes into contact with the cooler duct surfaces. Sealing any leaks in the ductwork can help alleviate this issue.
  3. Incorrect duct sizing: If the AC ducts are undersized, the air may not flow through them quickly enough, causing the cooled air to stay in the ducts longer and increase the chances of condensation. Properly sized ducts will allow for better airflow and minimize sweating.
  4. Location and design: Ducts that pass through unconditioned spaces, such as attics or crawl spaces, are more susceptible to sweating due to the temperature differences. Ensuring proper placement and design of ducts can help reduce condensation.
  5. High indoor humidity: If the indoor humidity levels are excessively high, the air entering the ducts will contain more moisture, increasing the likelihood of condensation. Using dehumidifiers or addressing the source of high humidity can be helpful.
  6. Paston Effect: AKA Cold Attic Syndrome – Usually occurs in coastal regions (South Florida) where too much moisture and saltwater air get into the attic space. This can drop the dew point in the attic and cause the AC ductwork to sweat. All Thermo has been in the AC ductwork services and Insulation business for 50+ years and we specialize in solving the Paston Effect and sweating AC Ducts! Call us today at 561-842-3336.
