When the heat goes out in Marietta, GA, the clock starts ticking, and the diagnosis depends entirely on what kind of system is doing the failing. On a gas furnace, the most common no-heat call we run is a flame sensor coated in oxide: the burners light, the sensor cannot prove the flame, and the board shuts the gas down after the third attempt 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. That's the place to start if you need a fix today.
When to Call for Heating Repair in Marietta
Catching these issues early helps you avoid costly problems. Keep an eye out for the following clues:
- Booming or banging at ignition, a sign of delayed burner light-off
- An outdoor heat pump coil that stays iced over
- A furnace that tries to light, clicks, and then quits
- Cold rooms in one part of the house while others are comfortable
- Frequent on-off cycles that never bring rooms up to temperature
- The thermostat calls for heat but the vents blow cold air or nothing
- Strange smells from the vents, especially rotten egg or burning
- Higher heating bills with less comfort to show for them
