First-time homeowners may find that there are many terms essential to maintaining their home that they do not know much about. We have all heard the word “duct” before, but what does this mean for us and our home?

Before we jump into ducts, let’s recap what we know about HVAC systems. HVAC stands for Heating, Ventilation, and Air Conditioning. HVAC is a heating and cooling system that not only monitors the temperature in the home but also works to improve indoor air quality by controlling humidity and filtering out pollutants in the air.

Ventilation, either natural or mechanical, moves air in and out of the system and home. Once the air is brought into the home, it enters a handling unit, where it is cleaned through filters to remove dirt and dust and other particles that we do not want floating around. Next, the system sends the air to be heated or cooled.

Ducts are part of the HVAC system, and a network of them run through your home in order to direct air into different rooms of the house. Ducts supply air, return air and exhaust air. Ducts can be used to deliver mechanical ventilation as described above, and to deliver the cleaned air to the appropriate rooms in the house after the air is purified and heated or cooled in the handling unit.

Properly installed ductwork is extremely important for climate control and the energy efficiency of the home. If the system is not installed properly or if it is damaged, it can throw off the equilibrium of the cooling and heating system, which will drive up energy bills and result in uncomfortable and inconsistent temperatures.

Air leakage is one of the major problems that can occur with ductwork. Ducts need to be completely sealed at the seams in order to avoid leakage. All seals must be covered with aluminum tape, so do not attempt to cover seals on your own. Despite the name, “duct” tape will not work!  If you notice any parts of the duct that are exposed, call a professional immediately to have this fixed. It is likely a small fix, but waiting too long could lead to failure of the entire system.

Homeowners should also be cautious when installing replacement windows or upgrading their insulation. This can cause changes in the ventilation which could affect the airflow in the ducts. Again, while this is not a serious issue, it should be evaluated by a professional to ensure no changes to the ductwork are necessary due to the changes made to the home.  

Cleanliness of the ducts is also a crucial element to the HVAC systems. Especially in the spring, pollen, dirt, and dust can all build up in your ducts. The ducts must be regularly cleaned to keep the air in your home fresh and avoid any health issues for your family. Not only can dirty air ducts cause health issues for your family, but it also reduces the efficiency of the system; if you have clogged air ducts, the unit must work harder to maintain optimal temperatures in the home.

It is essential to have a properly installed HVAC in order to get quality air to your home or business. Ducts are very delicate and essential to the system, so any repairs should always be made by a professional HVAC contractor. Professional installation is a must, and should always be done by a contractor who can evaluate your needs and ensure you get a system that’s efficient and effective for your specific home.
