Air Duct Cleaning questions, answered by experts

The time it takes to clean your AC unit depends on factors such as its size, the level of dirt buildup, and the thoroughness of the cleaning process. A basic cleaning can take anywhere from 30 minutes to an hour, while a more detailed cleaning involving disassembly and deep cleaning may take a few hours. Make sure you allocate enough time to ensure all components are properly cleaned for optimal efficiency and longevity of your AC unit.

If you have dirty vent covers, clogged air filters, noisy air ducts, or weak airflow, it might be time to get your air ducts cleaned. You should also call an HVAC professional if you notice any visible mold or believe that there are rodents or insects in your ductwork. Abnormally high energy bills can also be a sign of dirty ducts.

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.

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.

A calculation method that your HVAC contractor will use to ensure your system does what it's supposed to is measuring duct output, or its CFM. The calculation requires knowing the cross-sectional area of the ductwork and determining the air speed past any given point within it.
