Short answer
Boiler and heating work in Greater Burlington is a wet-side trade: hydronic piping, zones, circulators, radiation and combustion on delivered oil or propane. The specialists who do it well are not always the ones who do cooling, and a good estimate turns on whether combustion is tested with recorded readings instead of a visual check, whether zone, circulator, valve and air-elimination faults are actually diagnosed, and whether a replacement is sized from a heat-loss calculation, not the label on the old boiler. How a replacement affects domestic hot water, and how delivered-fuel service and run-out restarts are handled after hours, are also worth comparing directly.

When this is the wrong comparison
This guide covers boilers, furnaces, radiant and other fuel-fired heating. Cooling, ductwork, ventilation and controls are a separate trade, and a specialist in hydronics may not do them at all.
What a written estimate should show
Put these 6 points to every business and write the answers next to each estimate.
- Combustion testing with recorded readings, not a visual check
- Zone, circulator, valve and air-elimination diagnosis
- Whether replacement sizing comes from a heat-loss calculation
- Existing radiation and whether it suits a lower water temperature
- Domestic hot water and how a replacement affects it
- Delivered-fuel service, run-out restarts and after-hours terms
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 |
|---|---|---|
| Combustion | Readings recorded with an analyser and handed over | "Looks fine" |
| Sizing | Heat-loss calculation for the house | Same size as the old boiler |
| Radiation | Says whether existing radiators suit a lower water temperature | Silent |
| Hot water | Says how domestic hot water is affected | Not mentioned |
| After hours | Terms for run-outs and no-heat calls stated | "We are always available" |
Vermont licences and permits for this work
Anyone who installs, inspects or services oil, propane or natural-gas equipment in Vermont must hold a Certificate of Fitness from the Division of Fire Safety. That is the certificate that matters for a boiler, and the estimate should name the certificate holder.
Hydronic piping is plumbing work, so a boiler replacement that changes the piping brings in a licensed plumber as well. The Division also commissions boiler inspectors, which matters for larger or multi-unit pressure vessels.
What changes the job around Burlington
Delivered fuel is the local reality. In many Burlington-area homes the boiler burns oil or propane from a tank, so no-heat calls often begin with an empty tank or a run-out that left air in the line. A good estimate says how run-out restarts are handled and whether the price includes bleeding the line.
At the Essex Junction 1 N station the winter normal is about 7,300 heating degree days, so a boiler that is one size too large cycles constantly and wastes fuel through the cold months.
Warning signs in a written estimate
- Replacement suggested without a heat-loss calculation
- No combustion readings on a service visit
- Parts replaced one by one to see what fixes it
- No Certificate of Fitness holder named
- A price that ignores domestic hot water
Questions to ask before you sign
- Who holds the Certificate of Fitness for this work?
- Will you record combustion readings and give me a copy?
- How did you size the replacement?
- What happens to my hot water during and after the change?
- How are run-outs and after-hours no-heat calls handled?
