Nine months of heat, one month of real cooling
In Woodstock, a mini-split earns its keep in winter more than summer. Nights average 12°F from December through February, and the heating season runs September through May, nine months of the year. Cooling only matters in July, when afternoons average 77°F. Whatever gets installed has to be sized for that long, cold stretch first.
A lot of homes here still heat with fuel oil, and a mini-split installed to replace or back up an oil system needs to actually hold up on those 12°F nights, not just run. Any new unit manufactured now has to meet the federal minimum of 14.3 SEER2 for cooling and 7.5 HSPF2 for heating, but in a place where the real work is nine months of cold, the heating side of that rating matters more than the summer number does.

Vermont has no state license for HVAC contractors.
Vermont keeps no state record of HVAC contractors at all. No registration, no exam, nothing on file tying a name to this trade. Anyone can take on a mini-split installation here and call themselves qualified for it.
For this job, the protection comes from the local building office instead. A mini-split installation needs a permit in most cities and counties, and an inspection once the work is done. That inspection is what checks the installation was done right here, not a license.

- Is a mini split worth it?
- For most homes here, yes, especially as a way to add heat or cooling to a space without ductwork. Nearly half the homes in this area heat with fuel oil, and a mini split gives you an efficient backup or primary heat source that doesn't depend on that system. With winter nights averaging 12°F, look for a cold-climate model rated to keep producing heat at those temperatures. A contractor can walk through your specific rooms and heating setup to say whether it makes sense for your house.
- How many rooms can a mini split cover?
- A single outdoor unit can run one indoor head or several, depending on the system. Single-zone systems heat and cool one room or open area. Multi-zone systems connect several indoor heads to one outdoor unit, and each head is controlled on its own so you can set different temperatures room to room. How many zones your house needs comes down to the layout, and a contractor can size that out room by room.
- Can a mini split heat a whole house?
- It can, if enough indoor units are placed to cover every room, but that depends on your layout and how the house holds heat. A multi-zone system with heads in each main room can carry the full heating load, and cold-climate models are built to keep working through winter nights at 12°F and colder. Homes here need heat from September through May, so the system has to hold up for most of the year, not just take the edge off. A contractor can look at your floor plan and tell you what it would take to cover the whole house.
