Furnace vs Boiler in Juneau City and Borough, Alaska
When a furnace makes sense
If your house already has ducts, a furnace is the simpler choice. It heats air directly and a blower pushes it through the house, which recovers fast on cold nights, and nights here average 26°F from December through February. With heat needed close to 12 months a year, that quick response matters.
When a boiler makes sense
A boiler suits a house with radiators or in-floor pipes already in place, since it heats water and sends it through those lines instead of ducts. It runs about 5% cheaper here than a furnace does, which adds up when heat is needed close to 12 months a year. Where that piping isn't already there, it's a bigger change to take on.
