Heating and Furnace Repair in Sandy Springs

Did you switch the thermostat to Heat on the first chilly evening and get only silence? Or did the inducer hum, the igniter turn orange and then the whole thing quit? Maybe the blower runs but the registers deliver air that feels barely warm. Winters here are mild enough that a furnace can sit unused for months, which is exactly why problems tend to surface the first night it's truly needed. A gas furnace lights in a set order, and each step has its own common failure. The inducer motor has to start and prove draft through the pressure switch. The igniter has to reach temperature without cracking. The gas valve has to open, and the flame sensor has to confirm a flame within seconds or the control board shuts it down. A limit switch watches for overheating, which is often caused by a dirty filter or restricted ductwork. We test each step in turn, so the repair addresses the actual failure. Electric furnaces get the same methodical approach for heating elements, sequencers and relays. Please remember one thing above all: if you ever smell gas, get the household outdoors at once and reach the gas company or 911 from a safe distance, before calling anyone else.
