When the heat goes out in Dunwoody, GA, the clock starts ticking, and the diagnosis depends entirely on what kind of system is doing the failing. On a gas furnace, the single most frequent culprit is a flame sensor coated in oxide: the burners light, the sensor cannot prove the flame, and the board shuts the gas down three tries later and locks out. Close behind come cracked hot surface igniters, stuck pressure switches, clogged condensate traps on high-efficiency models, and blower motors that have quietly worn out. Heat pumps fail differently: a weak defrost cycle leaves the outdoor coil armored in ice, a failed reversing valve strands the system in cooling, and a dead outdoor unit leaves the electric backup strips carrying the whole house at several times the operating cost.
The repair homeowners call us about most is Furnace Repair. If something has stopped working, start there.
Warning Signs for Heating Repair
The sooner you notice these red flags, the easier and cheaper the fix. Watch for these telltale signs:
- The system starting and stopping every few minutes without warming the house
- The thermostat calls for heat but the vents blow cold air or nothing
- A heat pump's outdoor unit encased in frost or ice
- Clicking and failed ignition attempts before the furnace gives up
- Some rooms warm while others stay stubbornly cold
- Burning, musty, or rotten-egg odors when the heat runs
- Heating bills spiking while comfort keeps falling
- Booming or banging at ignition, a sign of delayed burner light-off
Act Before It Gets Worse
A failing capacitor, clogged condensate drain, or dirty flame sensor rarely fixes itself and usually gets more expensive to address the longer it runs. Don't wait, call (470) 200-3365 and we'll take a look right away.
