Four lakes, a lot of part-time houses and trucked-in fuel
Chestertown is the hub of northern Warren County's lake country. Brant Lake, Loon Lake and Friends Lake are ringed with camps and second homes; the hamlet has older year-round homes and a Main Street that has been there since the stagecoach days; Pottersville and the Route 8 and Route 9 corridors have farmhouses and newer builds. A large share of the properties are seasonal or part-time, which is exactly the situation a zoned heat pump is built for.
No gas line reaches any of it. Camps run on propane and electric baseboard; year-round homes run on oil and wood. Winter design temperature is about -10°F, and the hollows around the lakes run colder. For a part-time owner, the pain is not only the fuel price; it is coordinating a propane delivery for a house nobody is in, and hoping the tank does not run dry during a cold snap.
A Mitsubishi system changes that. Heat or cool only the zones in use, monitor it from your phone through the Mitsubishi Comfort app, hold 50°F all winter for a small electric bill, and have cooling in August. Year-round Chestertown homes get the same thing in reverse: dependable sub-zero heat at a fraction of oil's cost per BTU. Chestertown is about 50 minutes from Ticonderoga by Route 9 through Schroon Lake, and we group it with Warrensburg and Bolton Landing on our Warren County runs.

Why Mitsubishi Hyper-Heat works in Chestertown
Winter on Lake George is colder than most people downstate expect. Design temperatures around Chestertown run close to -10°F, the wind off the lake adds to it, and shoulder-season nights in April and October still call for heat. Mitsubishi Electric Hyper-Heating INVERTER (H2i) equipment delivers 100% of its rated heating capacity at 5°F, keeps operating to -13°F, and the H2i Plus and FS-series models we install run to -22°F.
Because the inverter compressor modulates rather than cycling, a Hyper-Heat system runs low and quiet most of the winter and only ramps up on the handful of nights that need it. That is also what makes it cheap to hold a camp at 50°F while you are away. We size from a room-by-room load calculation and tell you honestly whether a backup heat source still earns its keep.

What we install in Chestertown
Lakefront camps and year-round village homes need different systems. These are the ones we install most around Chestertown:
- Camp and second-home systems on Brant Lake, Loon Lake and Friends Lake with freeze alerts and remote control
- Propane and electric baseboard replacements, usually one to three zones
- Whole-home oil conversions in year-round homes in the hamlet and Pottersville
- Floor-mounted units for camps with knee walls and cathedral ceilings
- Farmhouses on Route 8 and Route 9 with a ducted air handler where a furnace exists
- Repair and maintenance on any brand, grouped with our Warren County service runs

Traditional HVAC →Heat pump rebates for Chestertown homeowners
Chestertown is National Grid territory, so NYS Clean Heat rebates run through National Grid rather than NYSEG. The program works the same way: Adirondack Heat Pumps is a participating contractor, the rebate is applied on the invoice, and whole-home conversions off oil, propane or electric baseboard generally qualify for more than a single room.
Seasonal camps qualify the same as year-round homes; the rebate follows the equipment, not the months you live there.
Programs and tiers change, so we do not print dollar figures here. We confirm your exact amount at the free estimate and file the paperwork for you. See rebates & savings and financing.
Run your numbers first. Our savings calculator compares your current oil, propane or electric bill against a Mitsubishi system and generates a $250-off code you can use at your estimate.

Heat pump questions from Chestertown homeowners
Can I manage my Brant Lake camp from downstate?
Yes. Every system we install can connect to the Mitsubishi Comfort app or kumo cloud, so you can set each zone, hold 50°F while the camp is empty and get a low-temperature alert if it ever drops.
Which rebate applies in Chestertown?
National Grid. NYS Clean Heat rebates through National Grid apply to qualifying Mitsubishi installs, seasonal or year-round, and we file them as a participating contractor.
How far are you from Chestertown?
About 50 minutes from Ticonderoga by way of Schroon Lake. Estimates are free, there is no travel charge on installs, and we group Chestertown with Warrensburg and Bolton Landing for service.
Will a heat pump replace my oil boiler as the only heat?
In most Chestertown homes, yes. Mitsubishi Hyper-Heat delivers 100% capacity at 5°F and runs to -22°F on H2i Plus models. We tell you after the load calculation whether your house still wants the boiler or a stove for backup.
Can you add cooling to a camp that only has baseboard heat?
Yes. A single- or dual-zone Mitsubishi system replaces the baseboard heat and adds cooling and dehumidification in the same install, and it is quiet enough not to carry across the lake.
