No two heating systems break the same way, and in Garland homes the first question on any no-heat call is what kind of equipment we are dealing with. Furnaces most often quit on an oxidized flame sensor. The burners fire, the sensor fails to confirm the flame, and after three attempts the control board closes the gas valve and locks the system out. Cracked hot surface igniters, sticking pressure switches, plugged condensate traps on high-efficiency units, and tired blower motors round out the usual list. Heat pumps have their own failure patterns. A defrost cycle that falls short lets ice build up on the outdoor coil, a bad reversing valve traps the system in cooling mode, and a dead outdoor unit hands the whole load to the electric backup strips, which cost several times as much to run.

Warning Signs for Heating Repair
Spotting the early warning signs lets you act before the problem gets expensive. Watch for these telltale signs:
- Burning, musty, or rotten-egg odors when the heat runs
- Higher heating bills with less comfort to show for them
- Clicking and failed ignition attempts before the furnace gives up
- The thermostat calls for heat but the vents blow cold air or nothing
- The system starting and stopping every few minutes without warming the house
- A heat pump's outdoor unit encased in frost or ice
- Some rooms warm while others stay stubbornly cold
- Booming or banging at ignition, a sign of delayed burner light-off
