Ductwork Replacement in Willis, Michigan

A new furnace on old ducts in Willis is a common disappointment, and we would rather prevent it than explain it afterward. On every installation estimate in Washtenaw County we check whether the existing ductwork can carry what the new equipment needs, and in the 1950s–80s rural ranches and farmhouses with scattered 2000s builds homes around Paint Creek the answer is often no. Temprasure replaces ductwork in Willis alongside the equipment when both are needed, commissioning them as one system, or on its own when the furnace is fine and the ducts are the only problem. The design, the materials, the sealing and the final measurements are the same either way, and the estimate is free.

Willis houses and what that means for duct replacement

The typical Willis house is a 1950s–80s ranch on a crawlspace or a shallow block basement, built by a farm family or an auto worker on a piece of split-off land, and heated by a furnace that has been replaced once or twice without anyone enlarging the ductwork. Many of these were originally on fuel oil, and we still find abandoned oil tanks in basements and oil-to-gas conversion furnaces that are long past their design life. The farmhouses along Bunton and Tuttle Hill Roads are 1870s–1920s two-stories with Michigan basements and a forced-air system threaded in after the fact, usually with cold upstairs bedrooms as the result. Scattered 1990s–2010s acreage homes are colonials and ranches on full basements with 80 or 90 percent furnaces, more often propane than natural gas. Manufactured and modular homes are a larger share of the housing here than in the rest of the county, and their package units and small downflow furnaces are a regular part of our work.

Finished basements and additions in Willis get ducted properly or they get a single run stolen from a bedroom above. The 1950s–80s rural ranches and farmhouses with scattered 2000s builds houses in Washtenaw County that have been expanded over the years, the family room added off the back, the room built over the garage, the basement finished for a teenager, usually have the second kind. On a Willis replacement or extension we calculate the load for the new space, size supply and return for it, and tie it into the trunk at a point that does not rob the rest of the house. Where the main trunk is undersized for the enlarged house, which is common near Paint Creek, we replace it as part of the job. The DTE Energy bill for the whole house usually drops when the system stops running long cycles to satisfy the one room that could never catch up.

Ductwork in Willis tells the story of the house. The 1950s–80s rural ranches and farmhouses with scattered 2000s builds near Willis Road east toward Sumpter and the Augusta-Sumpter township line often have original sheet-metal trunks with branch runs added over the decades, panned joist returns that leak into the basement, and flex duct in the newer sections out toward Bunton Road corridor that has sagged or been crushed. We repair, seal and replace ducts across Willis, about 18 minutes from our shop, and we start every duct job by measuring static pressure so the fix addresses the actual restriction rather than the one that is easiest to see.

Local details we plan around in Willis

• Private wells supply every home, and the water is hard with iron and sometimes sulfur, which eats water heater anodes and leaves sediment that needs flushing.
• Permits for Willis addresses go through Washtenaw County's building department, and inspections are scheduled on the county's southern-township rotation.
• All homes are on septic, and high-efficiency furnace condensate needs a neutralizer or a discharge point that does not feed the drain field.
• Willis is as flat as anywhere in Washtenaw County, and drainage is slow enough that ditches and field tiles run most of the spring. Crawlspaces near Paint Creek and along the lower stretches of Bunton Road stay wet into June, and that moisture finds its way into ductwork and furnace cabinets. Winter wind crosses the fields unbroken, and summer brings long humid stretches with little shade outside the old farmstead windbreaks.
