It’s easy to forget all about the air duct, then the network of pipes is essential to the operation of both the gas furnace plus a/c however largely concealed inside the walls plus ceilings.
The duct plan is responsible for pulling the stale air out of the rooms plus supplying the heated plus cooled air! If there are holes in the air duct or cracks at the seams, the conditioned air is allowed to escape; When the maximum amount of air fails to arrive at the numerous rooms of the house, the gas furnace or a/c are forced to run longer plus labor harder.
There is greater wear plus tear on components, but more energy is used, leading to higher energy costs. The same imperfections that allow the heated or cooled air to leak out can also draw in contaminants, neglected air duct frequently harbors harmful toxins such as dust, construction debris, bugs, webs, pollen, mold plus even decomposing rodents, but every time the gas furnace or a/c starts up, these pollutants can become airborne plus introduced into the breathing air, however health complaints such as congestion, sneezing, coughing, sore throat plus headaches can often be blamed on dirty air duct. The first time I had my air duct diagnosed by a professional HVAC dealer, they were allowing nearly thirty percent of the heated/cooled air to escape. I now make sure to have the duct plan checked every year. I’ve realized that the ducts directly impact the health, comfort plus efficiency of the living space. They significantly affect my budget plus the reliability plus longevity of the gas furnace plus a/c.
