• Manufactured Home Tests Reveal Duct's Top Problems.
• Delta T's Bruce Manclark and Ananda Hartzell conduct a duct test.
• "Humans have a limitless capacity to accidentally (or deliberately) punch, cut, puncture, rip or otherwise mutilate the duct system of a mobile home," says Bruce Manclark of Delta-T, an energy consulting and HVAC firm in Eugene, Oregon. He's coauthor with Bob Davis of Ecotope in Seattle, Washington, of an article on duct sealing in the January/February issue of Home Energy magazine.
• Much of the article applies to site-built houses as well, although site-built houses have their own set of recurring duct problems.
• Not surprisingly, the Home Energy article notes that duct leaks can reduce heating system efficiency by 32 percent. ... Other problem areas included register boot-to-floor and boot-to-plenum connections, slip joint connections, plenum ends and crossover duct connections. ...
• The three most common problems they see are the use of building cavities as ductwork, excessive use of flex duct and poorly designed duct systems.
• "Trading a smooth round duct for a rough rectangular surface inevitably inhibits air flow," he says. ...
• While Manclark admits that flex duct has its place, its low cost means contractors rely on it too heavily. ... He notes that while some flex duct will stand the test of time, he has seen cases where the duct's interior liner has dissolved after only ten or 15 years.
• Manclark also cautions that duct sealing isn't everything. ... "Good duct sealing can't overcome bad duct design. ...

• 31 LeDoyt Road U-38, Storrs CT 06269-3038 Air Duct Calculator.
• The Air Duct Calculator is a PERL/CGI script which allows users to size ductwork and calculate duct pressure losses. ...
• The program allows users to input a desired flow rate in CFM, a limiting velocity in FPM, air pressure in PSI, air temperature in degrees F, the length of the duct, and the duct material. The program then calculates the duct cross sectional area, the circular duct diameter, rectangular duct equivalents (with aspect ratios of 1. ... 0), air density, fluid viscosity, Reynold's number, relative roughness, the Moody friction factor, the Colebrook friction factor, the pressure loss in PSI, and the duct friction loss in inches of H20 per 100 FT of duct length. ...
• Slide-rule type duct calculators designed for standard air and galvanized steel ductwork do not allow users to correct for non-standard air conditions, or for other types of duct material. The Air Duct Calculator allows users to input any type of duct material, and can input any air temperature and pressure. ...

• Duct Sealing.
• Sealing leaks in your heating and air conditioning duct system can be one of the most effective energy improvements to your home. Duct sealing and repair can provide an opportunity for significant energy and cost savings, while also improving comfort. ...
• Ducts and duct systems have two very specific purposes. During the winter months, duct systems supply heated air throughout the home through supply ducts and return cooler air through return ducts for filtering and reheating. For homes with central air conditioning, in the summer, duct systems supply cooled air throughout the home and return warmer air for filtering, moisture removal, and recooling. ...
• Holes in your ducts allow air to escape from or enter your duct system, increasing your energy costs. ... These leaks allow unconditioned air from those same spaces to enter the duct system. Duct systems are often hidden from view, which makes finding leaks difficult. ...
• Duct sealing is particularly important in crawlspaces, as conditioned air that leaks into a crawlspace is totally wasted.
• What is Duct Sealing?.
• Duct sealing is the process of identifying and repairing holes in the home's duct system. ... This is followed by a duct pressurization test, which should be conducted by a qualified heating and air conditioning contractor or testing organization. This test, often called a "duct blaster" or "blower door" test, identifies the amount of air leakage in your duct system and where it is occurring. Common leakage sites are around air registers and grilles, duct connections, panned floor joists, and the heating and air conditioning unit itself. ...
• This seal will last for many years, unlike old-fashioned cloth duct tape. Other acceptable methods include: silicone caulk, duct sealer, and special foil tape. Duct sealer is available in cans and caulk tubes. ... Once repairs are made, a second "duct blaster" or "blower door" test should be conducted to confirm the reduced air leakage. ...

• The development of the Minneapolis Duct Blaster® has revolutionized performance testing of forced air distribution systems for builders, HVAC contractors, and utility DSM programs. The Minneapolis Duct Blaster is a calibrated air flow measurement system designed to test and document the airtightness of forced air duct systems in both houses and light commercial buildings. The Duct Blaster fan is connected directly to the duct system in a house, typically at a central return, or at the air handler cabinet. With the remaining registers and grilles temporarily taped off, duct airtightness is measured by either pressurizing or depressurizing the duct system and precisely measuring the fan flow and duct pressure.
• Duct airtightness measurements are used to diagnose and demonstrate leakage problems, estimate efficiency losses from duct leakage, and certify the quality of duct system installation.
• Minneapolis Duct Blaster.
• The lightweight Duct Blaster fan weighs just 7 pounds, but delivers enough air flow (an amazing 1,500 CFM) to test the leakiest duct systems. ...
• The Duct Blaster can be easily used in new construction applications where a Blower Door can't be used (e. ...
• The Duct Blaster can also be used as a powered flow hood to accurately measure air flows through the air handler fan, registers and grilles, and exhaust fans. ...
