"Susannah is a GEM! We love her and will never hire anyone else to clean our house. She has great attention to detail and goes above and beyond. After she leaves, we just point out things she did such as “She cleaned my mouse pad!” or “She cleaned the toaster oven!” And praise her work. She is professional, reliable, and does such a good job. She is worth every single penny and more. We are so lucky to have her!!"

Air Duct Cleaning FAQs, answered by experts

Whether air duct cleaning is worth the cost depends on your specific situation. While it hasn't been proven to prevent health issues, it can be beneficial for improving indoor air quality by reducing contaminants, which is especially important for households with members who have asthma or allergies. Cleaning is generally considered worthwhile if you notice visible mold growth, signs of a pest infestation, excess dust, or debris blowing from the vents. It is also recommended after a major home renovation. Additionally, if your ducts are dirty enough to leak air, cleaning and sealing them can improve your HVAC system's efficiency, ensuring the heated or cooled air reaches your living spaces and potentially leading to long-term savings.

Damp air from a humidifier can cause mold in ducts if it raises the air's humidity level too high for the duct system to handle or malfunctions, but it’s not a normal occurrence. To avoid mold trouble, set the humidistat to between 30% and 35% and inspect it often to ensure accuracy.

There are a few things you can do to help maintain healthy indoor air quality during construction. First, section off the area of your home where the work is taking place by hanging plastic sheets over doors to contain dust. Second, cover the vents in the construction zone using plastic sheets to prevent dust from entering into your ducts and circulating throughout your home. Finally, consider installing an air purifier that can scrub any stray particles out before you breathe them in.

Air ducts should be cleaned every three to five years, though the frequency can vary based on factors such as household conditions and local environmental factors. For homes with pets, smokers, or high dust levels, more frequent cleanings every two to three years would be necessary to maintain optimal air quality. If you notice persistent odors, significant dust buildup, or signs of mold or rodent activity, schedule a cleaning sooner.

Yes, dirty air ducts restrict airflow, reducing your HVAC's efficiency. This forces your system to work harder, increasing energy costs and wear and tear on your HVAC. Reduced airflow leads to uneven heating or cooling, seriously reduced indoor air quality, and can potentially trigger allergies or respiratory issues.
