"Technician that did the work was knowledgeable and friendly. The price was the best I had found in our area. The technician heard some jewelry being sucked out of the vent and he left the material in a bucket for me to sift through and I found a lost earring. It took 3 hours to do 12 house vents and the dryer vent. Great Job!!"

Air Duct Cleaning FAQs, answered by experts

Healthy air change per hour, or ACH, rates vary by room, usage, average occupancy, and volume. The minimum ACH that's considered healthy averaged throughout the home is 0.35. However, in rooms where humidity is an issue, such as bathrooms and kitchens, healthy ACH levels are between eight and 15.

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 should plan to change your AC unit's filter every one to three months, depending on the manufacturer's recommendations. You should also clean the coils at least once per year, but if you have pets or someone in your household has allergies, you might need to clean them more often. Fortunately, many pros will clean the coils and change the filter for you during an inspection, which you should schedule once or twice per year.

Focus on cleaning the air after you’ve finished cleaning surfaces. Use air purifiers, moving them as necessary from room to room. The air filters should be cleaned or replaced, depending on the type of filters you have. Clean the air ducts by yourself or by hiring a pro. Finally, open doors and windows to ensure the space is properly ventilated.

Whether an HVAC damper should be open or closed depends on the season, the zone it controls, and the temperature in that zone. In the summer, open upstairs dampers and close lower-level dampers to get the most efficient cooling possible. In the winter, do the opposite. Cool air will naturally flow down to lower levels, while warm air will rise. This keeps your system from working harder and helps prevent common AC problems.
