Understanding How A Duct System Works

HVAC systems provide great comforts to your home, and are readily available to meet your needs at the click or tap of a button. Often when we think of HVAC systems, we imagine furnaces and air conditioners, and we forget about our home’s duct system when it comes to HVAC maintenance needs. 

Your home’s ducts provide a process of transporting warm or cool air throughout your home to keep your living space comfortable. There are a few things you need to keep in mind to understand how a duct system works: 

  • What a duct system is 
  • How to care for your duct system
  • Duct systems status in a new home
  • How dirt and dust impact HVAC systems
  • Cleaning ducts regularly for best results

What Is A Duct System?

Your home’s HVAC system is a complex network of channels that provides cool or hot air throughout your home. Within the HVAC system is a duct system, which is typically made of sheet metal or flexible plastic and consists of supply ducts that deliver conditioned air to the rooms and return ducts that draw air back to the HVAC system. 

The duct system works by using a blower fan to push air through the supply ducts and back to the HVAC system through the return ducts, where it is conditioned and distributed again.

Do My Ducts Need Cleaned If I Have Air Filters?

Your HVAC system should have air filters as part of their setup, but the air filters are in place to cleanse the air coming in from the outside of your home. The filters don’t take into account that over time, the ducts themselves can have a buildup of dust and dirt, which impacts the quality of air in your home. Even dust mites and mold spores can make their home in your duct system which is why a regular air duct cleaning is good for your home!

Regular Air Duct Cleaning For Best Results

Keeping a regularly scheduled air duct cleaning will be most effective in keeping dust, bacteria, mold spores, pollen and other harmful germs out of your HVAC system and away from your family. It’s recommended to have a thorough duct cleaning every 3-5 years, but if you live in an area that is especially prone to dustiness, you might want to schedule a cleaning more regularly. 

If dirt, dust, germs and bacteria are left inside your duct system for too long during seasons of little or no use, they will quickly and easily spread throughout your home when it’s time to get your systems up and running again.

Duct Cleanliness In A New Home

During the building process for a new home, the air duct system is usually installed fairly early on since it’s quite interior in the home. During the construction process, it’s only natural that dirt, drywall dust, wood shavings, and cement particles make their way into the brand new duct system. Dust can also cause damage to the HVAC system’s coils and motor units due to the amount of construction work taking place. That’s a lot of dirt to account for in a home that hasn’t even been lived in yet! This makes it all the more important that the HVAC system be thoroughly cleaned before the home is in its new owner’s hands.

How Dirt And Dust Damage HVAC Systems

On the surface, dirt and dust might not seem like much more than an annoying, persistent visitor in your home, but they both can be very detrimental to HVAC systems as they accumulate and restrict the flow of air. They can clog air filters, impede airflow, and cause the system to work harder than necessary, leading to increased energy consumption and wear and tear on the components. 

The accumulation of dirt and dust can also lead to poor indoor air quality, which can cause respiratory issues, allergies, and other health problems for you, your family or anyone else who lives or stays with you regularly. Regular cleaning and maintenance of your HVAC system can help prevent these issues and prolong the life of your system.
