About South Mountain
South Mountain is the agricultural service hub between Mountain village and the South Branch of the South Nation River, and its HVAC profile sits at an unusual intersection: village-density housing on Main Street and County Road 13, plus a heavy concentration of working farms on the surrounding concession roads. Those are two genuinely different HVAC markets in one ZIP code. In the village core, we see the same pattern as much of older North Dundas — 1960s-70s bungalows with original sheet-metal ductwork, low-efficiency furnaces being replaced like-for-like by contractors who didn't measure static pressure first, and undersized cold-air returns that make the new high-efficiency furnace short-cycle. Out on the concessions, we're sizing systems for farmhouses with kitchen additions and converted summer rooms, plus the secondary heat loads of attached workshops and farm offices. South Mountain also has one of the few natural gas pockets in rural North Dundas — Enbridge service follows County Road 1 in places — so unlike most of our service area, the heat-pump-vs-furnace calculation is genuinely open here, and the right answer depends on whether your specific lot is gas-served or still on propane. We check the gas map before we quote, every time.

Why South Mountain Homeowners Choose Alpine Air
We Check the Gas Map First
Enbridge service is spotty in rural South Mountain — your neighbour might have it and you might not. We verify your specific lot before recommending equipment, so the proposal matches your actual fuel options.
Static Pressure Measured Before Quoting
The most common South Mountain call is 'my replacement furnace is louder and the back room is colder than before.' That's a ductwork problem the original installer didn't catch. We measure first, quote second.
Farm Outbuilding Heat
Workshops, farm offices, and converted milk houses all have HVAC needs. We design these as zoned systems with ductless mini-splits or unit heaters rather than wasting capacity on the main house furnace.
Real SD&G Pricing
We won't pad a South Mountain quote because we drove 'all the way out here.' This is core territory and we price it the same as Winchester or Morrisburg.
