If you have insulated air ducts and the insulation gets wet or moldy it should be removed and replaced as it cannot be effectively cleaned. If the conditions causing the mold growth in the first place are not corrected, mold growth will recur.
The EPA says regular ductwork cleanings are typically unnecessary. You'll want to get your ductwork cleaned if you have mold or pests. Replace your ductwork if you have major damage or an extreme mold infestation.
One common benefit of ductwork replacement is an increased efficiency in the operation of your HVAC system. Old ductwork can become cracked, dirty, and compromised, leading to your HVAC machinery having to work harder than necessary to heat or cool your home.
EPA does not recommend that the air ducts be cleaned routinely, but only as needed. EPA does, however, recommend that if you have a fuel burning furnace, stove or fireplace, they be inspected for proper functioning and serviced before each heating season to protect against carbon monoxide poisoning.
Duct cleaning has never been shown to actually prevent health problems. Neither do studies conclusively demonstrate that particle (e.g., dust) levels in homes increase because of dirty air ducts. This is because much of the dirt in air ducts adheres to duct surfaces and does not necessarily enter the living space.
Duct replacement costs typically range from around $20–$60 per linear foot, based on our team's market research. For example, if your home has 100 feet of ductwork, a complete replacement can cost between $2,000 and $6,000.
Ductwork typically requires replacement every 10-15 years, and delaying this can compromise airflow and energy efficiency. Visible and subtle signs, including excessive dust, strange noises, and increases in energy bills, can indicate deteriorating ductwork that needs repair or replacement.
OLD HOME, OLD DUCTS
Ductwork has a maximum lifespan of 20-25 years, and starts to deteriorate around year 15. If your ductwork is more than 15 years old, you may need to have the ductwork inspected to see if it is time to replace it. If it is older than 25 years, you almost certainly need to replace the ductwork.
However, DIY ventilation replacement is a task you should leave to an HVAC expert. Doing this task on your own isn't recommended because: Faulty installation will waste energy. Air leaks can cause your utility bills to rise.
Your homeowner's insurance won't cover cleaning, repairing or replacing your ductwork. What does a home warranty cover when it comes to AC units and ductwork?
Yes, installing a new HVAC system can increase your home value by 5% to 7% with a return on investment (ROI) of about 30%. This projected increase is especially true if you replace your current setup with an energy-efficient system, providing additional benefits to future buyers in the long run.
Vacuum-clean the Ducts
Attach a hose and a brush extension to your vacuum cleaner. Insert the hose into the ducts and move around to reach as many parts of the duct as possible. This will help you suction up the dust and debris you previously loosened with the brush. Repeat the process with all ducts.
For residential properties, air duct cleaning costs typically range from $300 to $500. Commercial properties, due to their larger size and more complex HVAC systems, can expect to pay anywhere from $450 to $1,000 or more.
Install Air Purifiers
Air purifiers are another great way to improve your home's air quality without resorting to professional duct cleaning services. Air purifiers work by removing toxins and allergens from the air before they have a chance to enter your ventilation system in the first place.
The Mess Is Minimal
If you don't have ducts, the spots that will see the most change are the closets and the attic, where we'll be running the ductwork. We'll have to cut a few holes in your ceiling to install vents and returns, but that's a very minor thing to do to drywall.
Dirty air ducts can cause a number of health problems, including allergies, asthma, and even respiratory infections.
On average, ductwork projects can take between one and four days to complete. The easiest duct projects without any complications are fairly simple jobs and can take as little as one day. However, there are many factors that can change that timeline.
Just how hard is it to replace ductwork? In short, the project requires meticulous attention to detail and a thorough understanding of HVAC systems. That's why Blue Frost stresses the importance of professional installation.
If you live in an older home with an original duct system, it's likely past due for replacement. Typically, duct systems have a lifespan of around 20-25 years, after which they may deteriorate, develop leaks, or accumulate dust and allergens.
Clogged air ducts can spread dirt, allergens, pet dander, and debris particles throughout your home, aggravating your allergies and lungs. This irritation can cause increased sneezing, coughing, watering eyes, and even increased asthma symptoms.
Duct cleaning can make a mess if not done professionally. Remember, cleaning your ducts involves removing the dirt from the ductwork and directing it to another place for safe disposal. If the process is done professionally, air pollutants accumulated in your air ducts will be disposed of properly.
