New Equipment, Old Houses, Honest Options
Walk the mechanical rooms of Amherst and you'll find a generation of equipment reaching the end at once: oil boilers hung in the '80s and '90s, propane furnaces from the first wave of conversions, all of it running on borrowed time. Replacement here comes with a question most towns never face — with no gas main under much of town to tie into, do you buy another delivered-fuel system, switch to a cold-climate heat pump, or pair the two?
Three Ways to Replace a Heating System in a No-Gas Town
Like-for-like is the simple path — a new high-efficiency oil boiler or propane furnace drops into the existing fuel setup and burns meaningfully less than a decades-old unit. The second path is a full switch to a cold-climate heat pump, trading the delivery truck for the electric meter. The third, increasingly common in Amherst, is the hybrid: a heat pump sized to carry most of the winter, with the boiler retained for the deepest cold. A good installer estimates more than one path and shows the assumptions, because the right answer differs between a tight 1990s garrison and a drafty antique.
What Careful Installation Looks Like in an Older Home
- A real heat-load calculation — antique framing, stone foundations, and patchwork insulation make square-footage rules of thumb useless here
- Right-sizing over up-sizing — an oversized system short cycles, and old houses punish that habit with uneven rooms
- Respectful routing — linesets, venting, and any new duct runs planned around plaster, paneling, and original framing rather than through them
- Chimney and venting checks — old masonry flues often need a liner before new equipment can vent into them safely
- Haul-away and cleanup — the dead boiler and the empty tank leave when the crew does
Replace on Your Schedule, Not the Weather's
The best month to replace a heating system is any month you're not desperate. Shoulder-season installs — spring and early fall — mean full equipment selection, time to compare quotes, and no scramble while the house sits cold. If last winter ended with you googling boiler noises at midnight, start estimates now, while the decision is still yours to make slowly.

Amherst Installation Questions
There's no gas on my street — what should replace my oil boiler?
You have three realistic paths: a new high-efficiency oil boiler, a switch to propane, or a cold-climate heat pump — on its own or paired with a smaller boiler. Which one wins depends on your fuel usage, your ductwork situation, and how long you plan to own the house. An installer who quotes two of these side by side is handing you a decision; one who quotes only the option he sells is handing you a pitch.
Will an installer insist on adding ductwork to my antique home?
A good one won't. Forcing ducts into a house framed before ductwork existed usually means lost closets, dropped ceilings, and chopped framing — and there are almost always better answers, from ductless mini-splits to compact high-velocity systems to simply upgrading the hydronic setup the house already has. Expect the layout conversation to start with what the house allows, not with what the catalog contains.
What happens to the old oil tank?
Removal can usually be arranged as part of the job — tank, lines, and fill pipe — and it's worth doing rather than leaving a decommissioned tank in the basement to worry a future home inspector. If you're keeping oil as backup, the tank stays and simply gets checked over. Either way, raise it during the quote so it lands in the plan and the estimate.
