DRYER VENT CLEANING SERVICES ROCHESTER HILLS, MI

Inspection – The Dryer Exhaust Duct Performance (DEDP) Test is designed to test a dryer exhaust duct that has been visually inspected and determined to be clean. If both are true, then the technician will proceed with the test. We will inspect the existing transition duct (where your dryer connects to the dryer duct) and the termination location (the location in which your dryer vent can be found on the exterior of your house. Typical termination locations are a wall, eave, or roof. We will inform the homeowner if any part of the dryer exhaust duct is not in compliance of code.
Cleaning – The technician will pace your dryer vent under negative pressure. The negative pressure will act as a vacuum to remove any dust, lint and other debris from your vent. If needed, this procedure will be completed both from your existing transition duct (where you dryer connects to the dryer duct) and the termination location (where the dryer vent is found on the exterior of your home). The technician will use tools that will not harm your existing dryer vent.

Attach Testing Equipment – Next, the technician will attach some equipment that will test the status pressure of your dryer vent.
Conduct Dryer Exhaust Duct Performance (DEDP) Test – First the technician will disconnect your dryer from the wall, hook up the pressure gauge, connect the dryer exhaust to the testing equipment, turn ‘on’ the dryer, and then record the pressure differential reading. The technician will take pressure readings at a minimum of three different locations on the dryer vent. Finally, the technician will compare the actual pressure reading to the performance tables. If the pressure readings or velocity results fall below the minimum threshold, the technician will identity the conditions that may be causing lower than average dryer vent performance.
Document Test Results and Make Recommendations – The technician will determine whether your current dryer vent system has ‘passed’ or ‘failed’ the Dryer Exhaust Duct Performance Test. Relevant factors to the test include estimated length of the dryer exhaust duct, actual backpressure readings, and maximum airflow velocity readings. The technician will also note whether any adhered substances are present, and will make any final recommendations to improve system performance and safety. If you dryer vent system fails the test, the technician will make the relevant adjustments to your system and retest.
