"Dyna-Kleen did an excellent job at cleaning the entire HVAC air duct system throughout our house. They brushed and power vacuumed all 32 supply and return vents as well as cleaned the HVAC system itself, including the coils, plenum, fan, motor and cage. They brought in a very large and powerful vacuum system and long hoses to get the dust and gunk out of the duct system. The crew of three spent 4 hours on cleaning the entire duct network and HVAC system and did an extremely thorough job, including cleaning up any grime created by their work. They were all very professional, friendly and informative. They honored their quoted price which was the best of all the estimates we got. Great all around."

Air Duct Cleaning questions, answered by experts

The most common duct sizes used in residential homes are round ducts 6 to 12 inches in diameter. This size is small enough to be easily installed into walls and ceilings, yet is wide enough to allow for adequate airflow through the home. Improper duct sizing can cause HVAC issues, increased energy bills, and a drop in HVAC efficiency, which translates into a less comfortable home. 

You won’t have to do much to prepare for air duct cleaning. Make sure your vents are easy to access, and move any nearby furniture or other objects out of the way. If you have a furnace or air conditioner unit, ensure they are easily accessible. And if you have a pet, make plans to get them out of the house, if possible. Vent vacuuming can be loud and requires access to all rooms, so you may want to take extra steps for pet safety.

If you don’t regularly change your HVAC filter, your system will get clogged up with contaminants, and as a result have to work harder to function properly. Eventually, this can cause a multitude of problems for your HVAC system and shorten its lifespan. Additionally, failure to replace your filter can lead to higher energy bills, poor temperature regulation, and even health problems.

Signs your ductwork needs cleaning include visible dust buildup, musty odors, increased allergy symptoms, and reduced airflow. If you see dust blowing from vents, find mold inside ducts, or notice a spike in your energy bills, it’s time for a professional inspection and cleaning to improve air quality and efficiency.

Ozone can damage building materials and belongings in your home, as the same oxidizing powers that allow it to remove odors can break down other things in your living space. However, it would take long-term exposure for any noticeable damages to occur. Since ozone smoke removal takes 24 to 36 hours, a treatment or two won’t have much of a negative impact on your belongings.
