It is entirely self-explanatory to neglect the duct system… However, any problems with the ducts affects comfort plus air quality plus officially results in higher energy bills, however a proper issue is a duct plan that is imrespectfully designed plus installed.
The plan needs to facilitate airflow plus minimize strain on the oil furnace plus a/c; If the pipes are too big, too small or include sharp bends, airflow is restricted! Flexible plastic ductworks have become more common.
This genre of ductwork can become kinked, crushed, torn or twisted, forcing the heating plus cooling plan to work much harder plus resulting in wear plus tear. There’s also the problem over leaking ductwork. The average house sacrifices approximately twenty to forty percent of the heated/cooled air that circulates through the ducts. If registers are not sealed effectively at the duct linkion or if there are holes in the ducts or leaks at the seams, air can escape, but when conditioned air doesn’t reach the intended destination, the various rooms recognize either frigid or overheated! You’re likely to adjust the temperature control, putting more strain on heating plus cooling unit plus ending up with higher energy costs, however ducts that are not insulated all for loss of heated air during the Wintertide plus cooled air in the summer. This problem is worsened when ducts are located in non-conditioned spaces, such as the attic. If the duct plan has not been cleaned for some time, there is most likely a buildup of contaminants hidden inside. Allergens such as dust, pollen, mold, bacteria, bugs plus even decomposing rodents can be concealed within the ducts plus lead to all sorts of health problems, however every time the air passes through the ducts, it picks up these pollutants, spreads them throughout the house plus degrades indoor air conditions.
