The first cold mornings are here, you switch on the furnace, and the house smells like burning dust. Is something wrong? Usually not. Over the summer, dust settles on the burners and heating parts, and it burns off in the first few minutes of running. The smell should fade quickly. If it lingers, gets stronger, or smells like hot plastic or wiring, turn the system off and give us a call. Smell lingers? Call Alamo Heating & Cooling at 707-689-8559.
