Furnace not igniting or blowing cold
Furnace won't ignite · blowing cold air · short-cycling · burning smell on first startup.

If you smell gas, leave the building right away without flipping switches or using phones inside, then call 911 or your gas utility’s emergency line from outside.
Pipes freezing while heat is out
If you will be away during cold weather, the American Red Cross advises leaving the heat on and set no lower than 55°F (Red Cross). If your Sioux Falls home’s heat has failed and freezing weather is forecast, call for service right away.
AC out during a summer heat wave
