Call out overnight if the house is dropping toward freezing, if anyone in it is elderly, very young or unwell, or if you smell gas or hear the CO alarm — in those last two cases leave first and call from outside.
General guidance, not advice for your specific situation. We do not publish cost estimates: almost no contractor here lists their rates publicly, so any figure we printed would be a guess you might plan around. Ask two of them.

Most often the burner is not lighting while the fan still runs, which a homeowner reads as "it is on but cold". A blocked filter or a snow-covered intake pipe can also trip a safety limit that shuts the burner down and leaves the fan moving air. If the fan setting on the thermostat is on ON rather than AUTO, it will blow room-temperature air between heating cycles and nothing is wrong at all.
Fifteen to twenty years is the usual range for a well-maintained unit, less if it has run without filter changes. Age alone is not a reason to replace one that works, but it changes the arithmetic on a large repair — a major part on an eighteen-year-old furnace is worth weighing against a replacement rather than treated as an obvious yes.
Any work on the gas side of a furnace must be done by someone holding a gas fitter certificate. Plenty of Calgary firms hold both plumbing and gas tickets, which is why so many listings here describe themselves as doing both trades. Ask whether the ticket holder is the person actually attending, not just someone on the payroll.
In a Calgary winter it can become one. A house that is dropping toward freezing risks burst pipes as well as discomfort, and that risk rises fast once it is unoccupied or the temperature outside is well below zero. If you smell gas or a carbon monoxide alarm sounds, leave the building first and call from outside.
