Frequently Asked Questions About Air Ducts, Dryer Vents, and Insulation

The process of cleaning your air ducts varies on your home. On average, you can expect the service to last between two to four hours. Larger homes or those with pets may take longer. The length of the service also depends on the last time you had an air duct cleaning — if it’s been a while, the service will most likely take longer.

More often than not, your air ducts just need to be cleaned. However, there are times when replacement is necessary. The most common cause is age — ductwork over 10 years old should be replaced, as you can expect degradation in the seams, seals, and connections. Other signs you may need a replacement include: lack of airflow, uneven temperatures throughout your home, damage, dents, or holes in the ductwork, mold growth, noisy operation, or improper installation. Contact Fresh Air Duct Cleaning to determine if you truly need your ductwork replaced or just cleaned.

We use state-of-the-art technology by leading U.S. manufacturers. Our two primary pieces of equipment are the Rotobrush® BrushBeast™ and Air-Care™ Negative Air Machines. The BrushBeast is equipped with four vacuum motors and a 420 RPM brush that removes dirt, dust, dander, pollen, and other pollutants — and vacuums them up as it goes so nothing escapes. The negative air machine connects directly to the air ducts, creates a vacuum, and filters out toxic gases including carbon monoxide and radon. Every technician is trained and internally certified on both machines.

Your dryer vent tubing should always be metal. If your tubing is plastic, have it replaced immediately — plastic dryer vent tubing is a fire hazard. Common metal duct types include: aluminum foil ducts (flexible and widely available), slim/periscope ducts (designed for tight spaces), and rigid metal ducts (the most efficient option, with a smooth interior that allows air to pass through at a higher rate).

Yes — many hardware stores sell dryer vent cleaning kits with a brush and flexible attachments. However, these kits are not as effective or thorough as the professional equipment our team uses. For a completely clean dryer vent, call Fresh Air Duct Cleaning.

Yes. Your attic is a critical area that directly impacts your home’s temperature and energy efficiency. Without proper insulation, outside temperatures will affect your indoor air and you’ll spend more on energy bills.

The R-value measures how well insulation prevents heat from entering or exiting the home. The recommended R-value varies depending on where you live. Energy Star provides a regional map to help determine the right R-value for your area.
