The two most important parts of any air-con system are the supply and return ductwork. Ductwork works hand-in-hand with your air handler to move air between rooms and also out of a home. Sometimes problems arise with the ductwork, which can lead to indoor air quality problems as well as decreased energy efficiency. Some common ductwork problems you may encounter are described below
IMPROPERLY SIZED DUCTS
The supply and return ducts must be sized appropriately to ensure proper airflow through your air-con system. If they’re too big, it can lead to temperature imbalances throughout the home hence the need for air conditioning repairs Perth. On the other hand, if they’re too small, then the blower motor will have to work harder than necessary, which can lead to premature failure and excessive energy usage.
Duct leaks allow conditioned air to escape into attics, basements and crawlspaces where it is wasted. Leaks can also occur when ducts pass through walls, floors and ceilings, allowing conditioned air to escape into unconditioned spaces. To diagnose whether you have a duct leak, hold a tissue near a vent with the fan on. If you feel a breeze coming out of the vent, you have a leak somewhere in your ductwork. Also, check for signs of dust blowing out of cracks in the seams between pieces of metal ductwork.
KINKS OR BENDS IN DUCT WORK
If your ductwork is severely bent or kinked, it could restrict airflow and cause poor circulation throughout your home. Don’t be afraid to straighten out any bends or kinks you see by hand. However, if this doesn’t solve the problem, you will likely need to replace the entire section of ductwork.
Corrosion can happen in any type of metal venting system, but it’s particularly common in galvanized steel ducts and older homes. The corrosive action reduces the diameter of the pipes and causes excessive friction loss, resulting in poor airflow. This will also cause the AC to work harder than it should to circulate air throughout the home and could lead to higher energy bills each month, therefore the need for air conditioning services Perth.
TRAPPED CONDENSATION IN THE DUCTWORK
Condensation can cause mould and mildew growth, which will impact the quality of your indoor air. This is also a problem for people who suffer from allergies, as mould spores can make their symptoms worse.
Dust and other debris collects on your filters over time, which prevents them from doing their job properly. You must change them regularly, or they will become clogged, which makes it difficult for air to pass through them efficiently.
IMPROPERLY LOCATED REGISTERS
Improperly located registers allow heated or cooled air to escape into unused rooms or areas, reducing overall efficiency and increasing energy costs.
There are several things that can go wrong with the ductwork in your home. Some common problems include holes and gaps, which lead to a loss of heated or cooled airflow into the house; sags and hangers, which create low-pressure zones; and too many elbows, causing air leaks. All of these problems are preventable and can often be solved by correcting improper duct installation practices used in your home by contacting DACS air conditioning.
