Your air ducts in your home play an essential role in providing continuous comfort through many different seasons. They circulate air from the heating and cooling systems throughout all of the rooms in your house. However, neglecting the structure of your air ducts can result in many problems. When your HVAC system is on, you do not want it to affect the health and wellbeing of you or your family. When your ducts become old and dirty, it may be time for a replacement. It may seem like a hassle, but there are many benefits to be had from getting your ductwork replaced:

The Benefits

Better Air Quality

Having your ducts replaced is pivotal in maintaining a healthy quality of air. By replacing your ducts, you reduce the risk of airborne particles spreading through the air ducts, such as pollen, pet dander, mold, and mildew. It will make breathing much easier, especially if someone in your home has any respiratory problems.

Reduces Allergens & Irritants

Any dust building up in the ducts can spread and settle onto your furniture, bedding, floors, and more. If it becomes too serious, it can cause a flood of allergy problems for any inhabitants of your home. Along with dust, people with allergies can be extremely sensitive to many airborne particles. An air duct replacement can prevent any further dust allergen issues.

Reduces Dirt & Debris

Much like the dust problem, dirt and debris can naturally collect in your duct system. This can create more issues as it gradually flows throughout your home, creating messes just where you finished tidying up. The debris can make a lining that attracts rodents that may be looking for a place to nest. It is something that can be prevented when you stay on top of maintaining your air ducts and knowing when it is time to get a replacement.

Reduces Odors

You may not think it, but dirty air ducts can create many bad odors that linger around your home. Every home has a particular smell, so you do not want yours to be considered to be foul. Bacteria and mold can build up in your ducts over time, creating a medley of terrible odors. Many houses can fall victim to rodent problems, which can cause further issues with droppings accumulating in your ducts. Air duct replacement can help prevent rodent issues, as they too can add smells to your home. Any additional odors, like tobacco smoke, pet smells, cleaning products, and paint fumes can be whisked away by a good replacement,

Improves Air Flow

A heavy build-up of dirt, dust, or grime in your ductwork can restrict the airflow from your air conditioner and furnace. Your system will have to work extra hard to cool or heat your home because of the dirty air ducts. When you replace your ducts, you get better efficiency in your airflow, as well as cleaner air to breathe.

Air Filters Last Longer

The job of your air filter is to stop any dirt or dust from entering the air you breathe. However, if there is too much dust buildup, the filter can get clogged faster than it should. You will constantly be purchasing new filters and replacing them more often. It is suggested that you use 30-day fiberglass filters or 3-month pleated filters. When you replace your ducts, changing filters will become an easier task.

Prolong the Life of Your HVAC System

The motor of your HVAC will experience more wear with dirty air ducts. It will have to work harder to push through the build-up, which can shorten its lifespan. It can impact your budget, as replacing a unit can be a hefty expense that can be avoided by maintaining your air ducts, and knowing when a replacement is necessary.

Lower Energy Use

According to the U.S. Department of Energy, 25-40 percent of the energy used in heating or cooling your home is wasted. Keeping your air ducts dust and dirt free can result in saving on your energy bill. Your unit will not have to use too much energy pushing through all the build-up when you replace your ducts. The unit will then be able to run at maximum efficiency while also saving you some money.
