One mechanic.
One van.
On purpose.
Vanderkamp runs no crews, no sales commissions and no waiting room, because every one of those things ends up on your invoice. What it runs instead is a high-roof ProMaster with a parts wall sorted by failure rate — igniters and flame sensors at hip height, because that is what a Michigan furnace actually breaks.
The trade calls it a truck stock problem. Solve it properly and four out of five calls end in one visit; solve it badly and every repair becomes two trips and a restocking story. The van is the business plan.
What rides along
For heat
Hot-surface igniters (three flavors), flame sensors, universal control boards, inducer motors, a blower motor in the two common frames, gas valves, thermocouples for the old stuff.
For cool
Run capacitors 35/5 through 55/5, contactors, fan motors, a hard-start kit, line-set fittings, and the vacuum pump that never gets skipped.
For both
Combustion analyser, CO meter, manometer, megohmmeter, and the license that says the readings mean something: Michigan Mechanical Contractor — fictional, like the rest of this site.
Where the van goes
Based in Livonia. Wayne and the near half of Oakland are the bread and butter; Washtenaw is routine. Same-day no-heat coverage holds inside that triangle — past M-59 or into Macomb it becomes an honest conversation about tomorrow morning, and you will hear that on the phone, not at the curb.
Livonia, Westland, Canton, Plymouth, Northville, Farmington, Redford, Garden City, Dearborn and the Heights, Novi, Ann Arbor, Ypsilanti. If your town is not on that list, ask — the answer is usually a drive-time, not a no.
