Furnace and Heating Repair in Sandy Springs

Because our winters are mostly gentle, a furnace can sit idle from April to November and then be asked to run for hours straight the first night the thermometer drops below freezing, which is precisely when a part that has been quietly wearing out decides to quit. Sandy Springs HVAC repairs gas and electric furnaces in single-family homes, townhomes, rentals and small commercial spaces, and we handle no-heat calls by following the furnace's own ignition chain one link at a time. On a gas unit that chain goes like this: a call for heat from the thermostat, the inducer purging the flue, a pressure switch proving draft, the igniter reaching temperature, the valve releasing gas and the flame sensor confirming ignition. Lose any link and the furnace stops, and the trouble is that every broken link feels the same from the living room. The findings we see most are a flame sensor wearing a thin coat of oxidation, an igniter with a hairline crack, an inducer motor that has slowed down, a high-limit switch that tripped because the furnace ran hot, and a blower motor or capacitor at the end of the road. Electric furnaces bring their own suspects in heating elements, sequencers and relays. Before calling, set the thermostat to heat and a few degrees above room temperature, confirm the power switch mounted near the cabinet has not been flipped off, and change the filter if it is clogged, since a starved furnace overheats and trips its limit. On gas odor there is no gray area: leave the house without touching light switches and call the gas company or 911. When the utility says it is safe, ring (770) 954-8245, and you will hear the repair figure before any part comes out of the box.
