Every furnace repair in Lubbock includes a combustion safety check — because a furnace that won't ignite is a problem, but one leaking carbon monoxide is a danger.

- Furnace blowing cold air instead of warm
- Furnace won't turn on at all
- Pilot light keeps going out
- Loud bangs, rumbles, or screeches at startup
- Furnace short-cycling or running constantly
- Yellow flame instead of blue (combustion issue)
