Duct Cleaning: The Good, The Bad & The Ugly
There are many conflicting opinions online about getting your air ducts cleaned. In fact the EPA says there is currently no research on the benefits so they are careful not to make a recommendation either way. Since we are your resource for all things HVAC, we'd like to give you the honest facts- good, bad and ugly, that will hopefully help you make your difficult decision more easy.
3 Good Reasons for Duct Cleaning
1. It never hurts to improve your air quality
Everything in your home will get dirty. Homeowners regularly invest time and money in cleaning dust, dirt and other allergens from many surfaces of our home and removing toxins from our water system. In addition to normal dust and dirt accumulation, any of the following environmental factors will eventually affect your air quality:
- cigarette or cigar smoke
- water contamination or damage to the home or HVAC system
- home renovation or remodeling projects
2. Potential Energy savings
When your HVAC system is clean, it doesn't have to work as hard to maintain the desired temperature. As pollutants pile up in the system, it has to work much harder, using more energy and costing more to work properly. When your ducts are cleaned out, your HVAC unit uses less energy and leads to improved cost-effectiveness!
3. Mold in these components could be making you sick
Contaminants and air pollutants, such as dander, dust, and chemicals are pulled into the HVAC system and re-circulated on average about 5 to 7 times per day. Over time, this recirculation will cause a buildup of these pollutants in the duct system. These pollutants affect the health of young children and the elderly more than anyone. This is why the National Air Duct Cleaners Association recommends homeowners clean their ducts once every three to five years. Furthermore, if you have allergies or asthma, autoimmune disorders or other respiratory health issues they recommend you consider having it done almost annually.
The Bad and Ugly Side of Duct Cleaning
Duct cleaning is a costly and messy process. To do it right all of the components will need to be removed and everything will need to be cleaned. This includes the supply and return air ducts and registers, grilles and diffusers, heat exchangers heating and cooling coils, condensate drain pans (drip pans), fan motor and fan housing, and the air handling unit housing. This is a very time consuming and costly process. Just running a spinning polyester brush through the ducts will leave 30% or more of the dirt in the ducts.
If you choose to go ahead with duct cleaning, now may be a good time to schedule it. Right before winter is one of the best times to get your air ducts cleaned out as your ducts will be blowing the most air during the winter months.
