Stone Mountain Furnace and Heating Repair

Our winters are mostly mild, so a furnace can sit idle for weeks and then get called on hard when a cold front drops overnight temperatures below freezing. That is when worn parts show themselves. Each heating call kicks off a relay race inside a gas furnace. The draft fan spins up, a switch senses the vent is drawing, the igniter turns orange, fuel reaches the burners, a thin rod checks for flame, and the blower finally pushes warmth out. A failure at any point and the control board shuts things down and tries again, which is why a furnace may click, glow, light for a few seconds and go quiet. Electric furnaces and air handlers have their own weak spots in heating elements, sequencers and limit switches. On an older furnace, the culprit is often a single part: a cracked igniter, a flame sensor coated with residue, an inducer motor with worn bearings, a limit switch tripping because a dirty filter starves the airflow, or a blower capacitor that has faded. Find that part, replace it, and the furnace often has plenty of service left. One thing comes before any of this: if there is any gas odor, get the family outdoors and let the gas company or 911 know from the street. Do not touch switches or try to relight anything. Once the utility has made the home safe, we can find out why the smell showed up.
