Duct cleaning is always a topic of heated discussion among friends and neighbors.Will it really benefit you and your family? What is really being done?
Knowing how the duct cleaning process works is the first step in understanding the need for your home to have a professional duct cleaning service performed. Over time, dust, dander and allergens build up in your ducts. These same substances also cling to other places – like your cooling coil, heating coil, blower and heat exchanger.
All of these airborne particles collect and inhibit the performance of your HVAC system. If you are going to have your air ducts cleaned, then it stands to reason that you want your home to have healthier air and that you want your climate control system to work more efficiently. Right?
Of course you do. Who wouldn’t want to live better and save money? Duct cleaning should be viewed as an all-inclusive cleaning job, not just a duct cleanout. A certified and reputable company can come out to your home and give you an estimate that includes duct cleaning as well as internal HVAC component cleaning.
Just look at it this way. Your air ducts got dirty for a reason. Our homes have become tighter than ever before because we strive to be more efficient with our energy bills.Once dust, dander and other airborne pollutants invade our home, they stay there.Your HVAC system runs off a supply and return system, meaning air is pulled from the return ducts, conditioned for heating or cooling, then sent back into the home through the supply ducts.
The air in your home (along with all of the pollutants) is circulated throughout your home five to seven times a day on average. That means that all of the dust and debris that did not catch onto the internal HVAC system parts or onto the internal walls of the air ducts, goes back into your home then the cycle repeats itself.
The simple fact is, no matter how much time you spend in your home, there is no way to stop dust and debris from entering and getting trapped there. That means that it has to go somewhere. If it is not airborne and circulating, then it has attached itself to something, most likely inside your HVAC system. This is why duct cleaning becomes a must for homeowners. For some people, the dust is a fairly harmless nuisance. But, for those who have autoimmune deficiencies,asthma or chronic respiratory illness, duct cleaning can substantially improve their lifestyle.
Inspect for yourself and see if your ducts have a dirty buildup in them. You might think that is an impossible task, but not really. Just take your camera phone and,with the flash on, stick it into your air duct and take a picture. If there is buildup of any kind, you will quickly understand why a duct cleaning service is needed. But, there are other reasons that duct cleaning is considered an important aspect to
healthier living. A good example of this would be air leaks in your ducts. As we all know, when you run your air conditioner, your condenser coil removes moisture from the air and discards it through a condensate drain. If there is a leak in your air
duct, then there is going to be mold growth because the moisture is not making it to the condenser coil, thus leaving the structural members in the proximity of the leak exposed to a steady stream of moisture. Over time, this moisture will rot the wood and/or insulation and also accumulate mold. The mold can then circulate throughout your home.
It is very important to get any mold accumulations cleaned out of your air ducts as well as the wood and insulation. Sealing ducts like this would also be highly advisable. You are not only providing a safe haven for mold and rot, but you are losing any conditioned air you produce and forcing your HVAC system to work harder to provide optimal comfort.
Duct cleaning can also help ensure that rodents and insects are not dwelling in your air returns. These critters are public enemy number one when it comes to spreading disease. To sum it all up, it would be in your best interest to call an experienced and licensed HVAC company out to make sure that your home air is healthy for you and your family. Your health and financial well-being will be better off.
