Short answer
Compare the company's actual experience with your building and system type, whether it is taking on a service call, a construction role or a design-build role, and how it plans a shutdown around occupied space instead of treating a business like an empty house.
Controls, electrical and trade coordination matter on any project with more than one contractor involved, and submittals, permits, commissioning and closeout are the difference between a project that is documented when it's done and one where nobody can say what was actually installed a year later. Emergency response and preventive-maintenance terms are worth comparing as their own line item, since a company that handles residential no-heat calls well does not automatically have the staffing or parts relationships a commercial contract needs.

Reading the estimate line by line
The table sets a strong answer beside a weak one for the lines that most often decide the total.
| Estimate line | A strong estimate says | A weak estimate says |
|---|---|---|
| Role | States service, construction, design-build or plan-and-spec role | Trades listed with no role |
| Shutdowns | Phasing plan with outage windows for tenants | "We'll coordinate" |
| Documentation | Submittals, permits, commissioning and closeout listed | Handover not described |
| Controls and electrical | Says who coordinates them and who is licensed | "By others" with no name |
| Ongoing service | Emergency and maintenance terms stated | Silent after installation |
Vermont licences and permits for this work
Commercial mechanical work uses the same Vermont licences as residential work: a licensed master plumber for plumbing, a Certificate of Fitness holder for fuel-fired equipment, a licensed electrician for wiring and EPA-certified technicians for refrigerant. The difference is scale and paperwork.
A commercial contractor should be able to produce insurance certificates for the property owner, name the licence holder who signs the permit and say whether a commissioned boiler inspector must look at any pressure vessel. Ask for those before mobilising.
What changes the job around Burlington
Burlington permits run through the Department of Permitting & Inspections, whose Trades Division issues construction permits and whose online portal takes applications for every permit it administers. On a commercial job the permit timeline can set the schedule, so the estimate should show when permits are applied for and who chases them.
Downtown and Old North End buildings are often occupied and old: piping and ductwork run through tenant spaces, and one shutoff can serve several businesses. Ask the estimate to name the hours work can happen and which tenants lose water or heat at each stage, because that difference is what turns a two-hour outage into a two-day one.
Warning signs in a written estimate
- Experience claimed with no matching building type or system size
- No plan for keeping tenants or customers comfortable during work
- Permits left to the owner with no explanation
- No closeout documents promised
- Emergency terms that only exist on the website
Questions to ask before you sign
- What comparable buildings and systems have you worked on?
- Which phases need a shutdown, and how long is each?
- Who applies for permits and books the inspections?
- What documents do we get at closeout?
- What are your emergency response and maintenance terms after the project?

Common questions
Are commercial plumbing and HVAC licences different in Vermont?
The licences are the same: master plumber, Certificate of Fitness for fuel-fired equipment, licensed electrician and EPA refrigerant certification. What changes is scale, insurance and documentation.
