Alburgh asks for 11 months of run time from a mini-split
Winter nights average 13°F here from December through February, and homes need heat from September through May. That is nine months of heating, then two more of cooling in July and August, when afternoons average 78°F. Only a few weeks a year ask nothing of the system at all.
A mini-split installed here has to hold its output on the coldest nights of the year, not just take the edge off a mild one. Any unit made from 2023 on has to meet 7.5 HSPF2 for heating and 14.3 SEER2 for cooling, the same federal floor as any other split-system heat pump. Almost half the homes here still heat with fuel oil, so a mini-split sized for these winters is doing real work, not backup work.

Vermont has no state license for HVAC contractors.
Vermont keeps no state record of who installs mini-splits. There is no test to pass and no license number tied to the business doing this work.
With no state license to point to, the check on this job most likely comes from the town. In most cities and counties, installing a mini-split needs a permit from the local building office, and an inspection once the work is done. That inspection is a local check, not a state one, because there is no state rule for this trade here.

- Is a mini split worth it?
- For most homes here, yes, but it depends on what's heating the house now. Alburgh sees winter lows around 13°F, and cold-climate mini splits are built to keep working at those temperatures. If you're heating with fuel oil, which close to half the homes here still do, a mini split can cover the shoulder months and take some of the load off the oil system the rest of the year. A contractor can look at your house and tell you what size and how many heads make sense.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, depending on the system. Each indoor head is sized for the room it's in, so the number you need depends on how many rooms you want heated and cooled separately. A one-room addition might only need a single-zone system. A house with several bedrooms and a living area usually needs a multi-zone setup, and a contractor will size it room by room rather than guess at a whole-house number.
- Can a mini split heat a whole house?
- It can, if it's sized and placed for that from the start. Homes here need heat for 9 months of the year, September through May, with winter nights averaging 13°F, so the system has to be rated for real cold, not just mild weather. A whole-house mini split setup usually means a head in every main room, sized to cover the house at its coldest, and a contractor will work that out room by room rather than off one general figure.
