How we work with commercial customers
Commercial work is priced hourly plus parts rather than flat-rate, because the equipment population in Twin Ports commercial buildings is far too varied for a price book to be honest about. We tell you the rate and the estimated hours before we start.
Every visit produces a written report per unit: equipment identified by tag and serial, the readings taken, the work performed, parts used, and recommendations separated into needs-attention-now, plan-for-this-year, and monitor. That structure is what turns HVAC from a series of surprises into a line you can budget.
For property managers and multi-site owners we maintain a per-address equipment list — model, serial, age, refrigerant, filter and belt sizes — so a call about "the unit over the north end" does not begin with a scavenger hunt. We will build that inventory during a survey and you keep it whether or not you sign an agreement.
Why cold-climate commercial is its own problem
Commercial equipment here fails from weather more than from run hours. Ten months of freeze-thaw, snow load and salt-laden air off Lake Superior corrode cabinets and coils, seize economizer dampers, and freeze condensate lines that drained perfectly in October.
That makes the failures predictable, which is the whole argument for scheduled maintenance. A stuck-open economizer heating subzero outdoor air through a Duluth winter is invisible from inside the building and can add thousands to a heating season. It is found on a maintenance visit, or it is not found at all.
