Ductwork Replacement in Northville, Michigan

Houses in Northville that were built in the Victorian-era two-stories downtown and 1970s–2010s colonials in the surrounding subdivisions have ductwork from that era, and a good share of it has reached the end. Temprasure comes out to the Randolph Street blocks and anywhere else in 48167 with a manometer and a light, measures the static pressure the blower is fighting, walks the trunk and branches and returns, and tells you honestly whether sealing and a new return will get there or whether the system needs to come out. When it is replacement, we design it for the house as it is now, install it in a few days with the basement disruption spelled out in advance, and balance it with numbers you keep.

Northville houses and what that means for duct replacement

Northville's housing splits sharply between the historic city and the township subdivisions. The Cady Street district and the blocks off Main and Center are 1870s to 1920s two-stories and Queen Annes with Michigan basements, fieldstone walls and low ceilings, where the ductwork was retrofitted and the furnace location is usually a compromise. Some of these houses still have steam or hot-water radiators fed by boilers that have been rebuilt more than once. The Beal Town and Randolph Street blocks have 1920s to 40s bungalows with small basements and finished attics. Beyond the city, the township's 1970s colonials and quad-levels in Northville Hills and Highland Lakes are on block basements with original trunk-and-branch duct, and the 1990s to 2010s subdivisions off Seven Mile, Six Mile and Beck Road are large colonials on poured basements with two systems, zoning and, often, a furnace in the attic serving the second floor. Water heaters in the newer houses are 50-gallon or power-vented gas units, and 75-gallon tanks are not unusual.

Two-story subdivision houses in Northville from the Victorian-era two-stories downtown and 1970s–2010s colonials in the surrounding subdivisions are the second most common replacement. The basement trunk is usually fine; the problem is the attic. Flex duct was pulled between the trusses in the Randolph Street blocks twenty or thirty years ago, and it has since sagged, kinked, been crushed by stored boxes, chewed by mice and patched with tape, and the single return in the upstairs hall was never enough. Past a point, patching is throwing money at it. We replace the attic system with a designed layout: shorter, straighter runs, rigid metal where a chase allows, insulated flex kept to the last few feet, and a dedicated return on the second floor. The upstairs of a Northville colonial in 48167 comes within a degree or two of the first floor when it is done.

We run duct work across Northville, about 28 minutes from our Ypsilanti shop, and the jobs cluster in the Victorian-era two-stories downtown and 1970s–2010s colonials in the surrounding subdivisions near the Cady Street historic district, Northville Hills and Maybury State Park. Leaky returns in a Wayne County basement pull in moisture and dust; undersized supplies starve the coil in summer and overheat the exchanger in winter. Sealing and repairing what is there solves most of it. Replacing a trunk or rerouting a run solves the rest, and we tell you which your house needs after measuring, not before.

Local details we plan around in Northville

• Northville's historic district commission reviews exterior changes on designated downtown properties, which can constrain where a condenser or a PVC vent termination goes.
• The city sits in two counties and permits run through the city building department regardless, but township addresses just outside the limits go through Northville Township.
• Boilers and radiators are still in service in a meaningful number of downtown houses, and we work on those systems as well as forced air.
• Northville is hilly for Southeast Michigan, sitting on the moraine ridge that runs through Maybury State Park, and the elevation plus heavy tree cover keeps the historic district a few degrees cooler on summer afternoons than the flat suburbs to the south. The Middle Rouge and Johnson Creek run through the downtown valley, and basements along them carry moisture. The open high ground along Seven and Eight Mile takes winter wind with little obstruction.
