Book furnace repair in Circle Pines any day, 7am–9pm. You see a flat-rate price on paper before any work, and the $79 trip charge comes off once you approve the repair. Gas here comes from the city's own Centennial Utilities, so a gas smell goes to them first and the furnace comes to us.
Most furnace calls in Circle Pines come from houses built in the 1950s and 60s, in basements that have held three or four furnaces. The ductwork is original, the return is often a single grille that was never enlarged when central air arrived, and a loaded filter on that small return can overheat the heat exchanger until the high-limit switch shuts the burners down. Newer 96% furnaces in the same basements fail in the usual places: flame sensors, igniters, inducer motors, and the condensate trap and hose that feed the pressure switch.
The gas side has its own division of labor here. Centennial Utilities, the city-owned gas company, handles everything up to and including the meter, so low pressure or an outage on that side is the utility's to fix. Past the meter, the house piping, the furnace and its venting belong to the homeowner, and that's the equipment we repair and test.

Try one reset first: switch the furnace off for a minute, then back on. After gas service is restored, air can linger in the house piping, and a furnace that fails to light a few times in a row locks itself out, often for about an hour. If it still won't light after a reset, call us. We check gas pressure, the igniter and the flame sensor, and anything the utility tagged off stays off until it's inspected.
Maybe, but read the bill first. Centennial's customer guide points to the days in the billing period, colder weather and changes at home, and it adjusts readings for the heat content of the gas, which varies month to month. If usage is still high for the weather, suspect the furnace: a clogged filter or weak blower stretching every cycle, short-cycling on a faulty limit or sensor, or a thermostat schedule nobody set. A tune-up from $129 checks it.
