Furnace Repair in Columbia Heights, MN
Furnace repair in Columbia Heights' houses from the 1910s through the 1950s starts with a $79 trip charge, waived when you approve the repair. Cramped basements and converted gravity ductwork are common, and we repair both furnaces and hot-water boilers.
Furnace repair calls in Columbia Heights homes
Columbia Heights houses are older and smaller than most in Anoka County, and the furnace often sits in a cramped basement with a low ceiling and the laundry crowding it. Many replaced a gravity furnace years ago, so the ductwork is a converted gravity system: big, low-velocity trunks and sometimes a single large return. A modern furnace on those ducts can overheat and trip its limit switch if the return is restricted, so a limit code isn't always a bad switch.
The other common setup is hot-water radiators on a boiler, especially in pre-1930 houses on the old streetcar blocks near Central Avenue. Boiler calls here involve circulator pumps, zone valves, air in the upper radiators and waterlogged expansion tanks. On furnaces and boilers alike, the chimney matters. These houses mostly vent into a masonry chimney, and a draft check, with a look for spillage at the draft hood, belongs on any furnace or water-heater service here.

Furnace repair in Columbia Heights: questions
Our Columbia Heights furnace keeps tripping its limit switch. Is the switch bad?
Sometimes, but in older houses the switch is usually doing its job. A converted gravity system or a single central return can starve the furnace of air, and a packed filter or closed registers make it worse, so the heat exchanger overheats and the limit opens. We measure temperature rise and static pressure. If airflow is the problem, a larger filter, another return or a blower speed change fixes it; a new switch alone won't.
What goes wrong with the radiator boilers in older Columbia Heights houses?
Most calls come down to a few parts: a circulator pump that hums without moving water, a zone valve stuck shut, air trapped in the upstairs radiators, or an expansion tank that has lost its air charge, which makes the relief valve drip. The boiler's own ignition and controls fail much like a furnace's. We bleed, test and price the repair in writing. Never cap a dripping relief valve.
