Now installing Veteran-owned In-window heat pumps across the North Country
Heat and AC without the construction.
A cold-climate heat pump that mounts in your window. No outdoor unit on a pad, no refrigerant lines drilled through your walls, no drain to plumb. It heats straight through a New Hampshire winter, cools all summer, and costs far less to run than oil, propane or baseboard heat. Most installs take an afternoon.

Two quick ways to find out if it's right for you
How much could I save?
Answer three simple questions about how you heat your home today. We'll estimate what you could save each year compared with oil, propane or electric baseboard heat.
Estimate my savings →Will it fit my window?
We'll walk you through a few easy measurements, one at a time, with pictures. At the end you'll know whether your window looks like a fit.
Check my window →Who it's for
Anyone who wants to skip the construction
Renters and homeowners alike. No holes through the wall, no outdoor unit, no line sets running up the siding. It mounts in an existing window and comes out cleanly if you move or renovate.
Anyone tired of high heating and cooling bills
Let the heat pump carry the spaces you use most and let the boiler or furnace rest. Efficient air conditioning in the summer comes with it.
Spaces your system doesn't reach
Additions, apartments over the garage, sunrooms, finished attics, workshops, or the bedroom that never gets warm. Add heating and cooling without extending ductwork or pipes.
How it works
Check your window
Use our step-by-step fit check, or just call or text us. Tell us your window's measurements, or send a photo and we'll help. We confirm the fit before anything is ordered.
Reserve your unit
A deposit orders your unit. It usually arrives within a few days.
Installation
Our two-person crew mounts the unit, seals the window and tests everything. Most installs take about half a day, and your window still opens afterward.
Setup
We connect the Wi-Fi app, walk you through the remote, and haul away all the packaging.
Pricing
- Includes the heat pump, fit check, delivery, mounting, window sealing, Wi-Fi setup and packaging removal.
- Discounted pricing for each additional unit installed at the same property.
- Discounts available for military members, veterans, first responders and teachers. Just ask when you call.
- Standard installation covers a typical first-floor window. Specialized installations that need extra work, like upper-floor windows or sill build-outs, are quoted separately after the fit check.
Introductory offer: for our first 10 customers we’re waiving the standard installation fee, so it’s $2,995 installed (regularly $3,295). Specialized installations that need extra work are quoted separately. Call or text 802-424-0471 for details.
Deposit due when your unit is ordered, balance at installation. Because opened units can't be returned to the manufacturer, we always confirm the fit first.
Questions
Can I still open the window?
Yes. The brackets that hold the window snug against the unit fold back, so the window opens normally.
Does it really work in a North Country winter?
Yes. It keeps heating in outdoor temperatures as low as −22°F, with no electric-resistance backup coil doing the work.
Where does the water go?
The unit manages its own condensate. There's no drain line and no bucket to empty.
How loud is it?
It has a silent mode for bedrooms, and the saddle design keeps most of the machinery on the outdoor side of the window.
How many will I need?
Each unit delivers up to 9,500 BTU. Our savings calculator estimates how many units your space needs, and we confirm it during the fit check.
What if my windowsill is thin?
No problem. If your sill is thinner than the unit needs, we can build it out. Sill build-outs are quoted separately after the fit check.
