The Ductwork

It is not necessary to become a certified HVAC technician, but a homeowner ought to have an understanding of the air-conditioning system that cools his or her home during warm months. The ductwork is not something out in the open to be seen, yet it plays a very important role in keeping the house at a comfortable temperature.

The Basic Operation

Air is drawn into the air conditioning system by fans and within the Air Handling Unit (AHU) the air is cooled. The air is then circulated back into the living space through the ducts, and returned to the air-conditioning unit by means of the ducts. It is the circulation that can cause some of the difficulties commonly experienced with this part of the HVAC system.

Problems in the Ductwork

It is possible that dirt and dust can accumulate in the ductwork and these create obstacles to the airflow. They can require the system to generate more energy to get the air circulating, and that becomes a cost to the homeowner. Perhaps more serious would be leaks in the ductwork that allows cool air to escape. It can also cause warm air from the outside to enter into the circulation system. Either can generate additional cost for the homeowner.

The problems are not dangerous in and of themselves but they do create a situation where the air-conditioning is not performing as well as it can. This can be a problem in the summer when the air-conditioning is in continual use. Problems with the ductwork will generate greater utility bills and less efficiency. A certified HVAC technician is best qualified to take care of cleaning the ductwork. This person has the proper tools and skill set necessary to do a good job. An annual inspection of the ductwork can also identify problems that can be fixed before they are serious, saving a homeowner a significant amount of money in the long run.
