"Really amazing job. They stayed longer than the intended timeframe, to make sure everything was scrubbed down (even in hard to reach areas, etc). They also were very reasonable. I had to insist on giving them more than they were charging, because of the extra time they spent on the job."

Air Duct Cleaning FAQs, answered by experts

If one room is significantly colder than the others, closing the air vents in the warmer rooms may seem like a way to redirect airflow. However, closing air vents is usually not a good idea. When the vents are blocked, your HVAC system will have to work harder, leading to higher energy bills and potentially shortening the life of the system.

One of the most common but overlooked symptoms of damaged ductwork is a spike in your utilities bill or an inability to heat or cool the house as you previously could. When ductwork is damaged, it tends to bleed air, and the result is you're paying to cool or heat your crawl space instead of your house. For handy DIYers, you might be able to find the damage by going into your crawl space, but for those unable to, you should pay a professional for an air duct inspection.

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 clean your air conditioner at least once per year, but you may need to clean your whole HVAC system (including the air ducts) more often. According to the National Air Duct Cleaners Association, you may need to clean them more frequently depending on factors like whether you smoke, have pets, or have allergies.

How often you change the filters in your return air vents typically depends on factors such as your indoor air quality, the type of filter used, and the specific needs of your HVAC system. Generally, checking your filters every 1-3 months is recommended. However, if you have pets or allergies or live in an area with high dust levels, more frequent replacements may be necessary. Regular filter changes ensure that your HVAC system operates efficiently, maintains good indoor air quality, and extends its lifespan.
