Short answer
Ductless work is judged on placement and honesty about coverage. A head heats and cools the room it is in and struggles past a closed door, so the single most useful thing an installer can tell you is which rooms the design explicitly does not serve. Multi-zone systems add a second trap: rated capacity is shared and derated across heads, so the sum on the brochure is not what you get with every head calling at once: ask for the real combined output. Also compare manufacturer training tied to the exact brand being proposed, head placement suited to how the room is actually used, and outdoor elevation above snow with drainage below it.

When this is the wrong comparison
Adding ductless heads to specific rooms is its own project. Heating an entire building with heat pumps, sizing against a whole-house heat loss, deciding what happens at the design temperature, upgrading the electrical service, is a larger project with a different comparison. Use the other guide for that.
What a written estimate should show
Put these 6 points to every business and write the answers next to each estimate.
- Which rooms the design explicitly does not cover
- Multi-zone derating, and the real output with every head running
- Manufacturer training tied to the brand actually being proposed
- Head placement, and whether it suits how the rooms are used
- Line-set route, condensate path and where the drain terminates
- Outdoor elevation above snow, clear of roof runoff, with drainage below
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 |
|---|---|---|
| Coverage | Lists which rooms the design does not heat or cool | "Whole-house comfort" |
| Output | Real combined output with every head running | Sum of the rated capacities |
| Placement | Head and outdoor-unit locations shown, snow clearance stated | Placement decided on the day |
| Line set and drain | Route, condensate path and drain termination described | Not mentioned |
| Electrical | Panel capacity checked, circuit and permit priced | "Electrical extra" |
Vermont licences and permits for this work
A mini-split job has three separate regulated pieces. Permanent wiring and any new breaker or disconnect belong to a licensed electrician under Vermont's Electricians' Licensing Board. Refrigerant handling needs EPA Section 608 certification. Any fuel-fired backup that is touched needs a Certificate of Fitness holder from the Division of Fire Safety.
Most reputable installers work through an electrician or employ one. The estimate should say who, because the electrical permit is often what holds a job up.
What changes the job around Burlington
Rebates are tied to the address. Efficiency Vermont offers a $375–$475 instant discount statewide for ductless heat pumps. Burlington Electric Department customers can get $2,100 or $2,500 for a mini-split, and Green Mountain Power customers get $2,000 per condenser if the household is income-qualified. The proposal should say which one it assumes.
Snow decides where the outdoor unit goes. It needs to sit above drifts and clear of roof runoff, with drainage below it, and Burlington yards and shared walkways often limit the choices. That is why a site visit that looks at the wall behind the outdoor unit is more useful than a phone quote.
Warning signs in a written estimate
- A promise of whole-house comfort from a single head
- No mention of rooms the design will not reach
- Multi-zone capacity quoted as the sum of the heads
- Outdoor unit on the ground where snow will bury it
- Electrical work assumed to be in the price when it is not
Questions to ask before you sign
- Which rooms will this design not heat or cool well?
- What is the combined output with every head calling?
- Where will the outdoor unit sit relative to snow and roof runoff?
- Who is the licensed electrician, and who pulls the permit?
- Which rebate is in the price, and who files the paperwork?

Common questions
How many mini-split heads does a house need?
It depends on the rooms you want to serve, not the floor area. A heat-loss calculation for each room gives the number; a head does little for a room behind a closed door.
