Heat pumps and mini splits in Whatcom Falls

The houses in Whatcom Falls

The Whatcom Falls neighborhood surrounds the park of the same name, and its housing is mostly postwar to 1970s — ramblers, split-levels and daylight-basement houses on wooded lots, with newer construction on the streets running toward Lake Whatcom. Lots are larger and greener than in the older west-side neighborhoods, with mature conifers and, in several places, a creek or a ravine crossing the property. Attached two-car garages and crawlspaces are the norm.

What is probably heating yours right now

A mix of gas furnaces on original ducts and 1960s-era electric forced air, with baseboard in the daylight basements that were finished later. Wood stoves and inserts are more common here than in the city core, partly because the neighborhood reads as forested and partly because of long outage-prone lines under the trees. Electric furnace and baseboard homes qualify for the PSE conversion rebate; a wood-stove household should ask about the Northwest Clean Air Agency change-out program before buying anything.

What makes a Whatcom Falls install different

Part of this neighborhood drains into the Lake Whatcom watershed, so anything involving ground disturbance or new impervious area near the lake side gets more attention from the City than the same work would on the west side; we keep pads minimal and handle condensate deliberately. The tree cover is a two-part problem: needles and duff pack an outdoor coil fast, and the same canopy means branch and windthrow risk over the condenser location, so we place the unit clear of the drip line where the lot allows it. On the ravine lots, verify there is a legal, level location for the pad before any equipment is ordered.

Sizing for 19°F

Every Bellingham address shares the same code design temperature — 19°F at station Bellingham 2 N, colder than Sea-Tac's 24°F. What differs street to street is the envelope. A 1910s one-and-a-half storey with knee walls and original single glazing carries a very different load from a mid-2000s two-storey built to a modern code, even at identical square footage. That is why we run the load rather than multiplying square feet by a constant.
