No two heating systems break the same way, and in Walnut Creek homes the first question on any no-heat call is what kind of equipment we are dealing with. Gas furnaces most often stall 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 underperforms 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.
The repair homeowners call us about most is Furnace Repair. That's the place to start if you need a fix today.
Warning Signs for Heating Repair
The sooner you notice these red flags, the easier and cheaper the fix. These are the signals our technicians see most often:
- Banging at startup caused by burners lighting late
- Thick ice or frost covering the heat pump outside
- No warm air at the registers even with the heat turned up
- Strange smells from the vents, especially rotten egg or burning
- Heating bills spiking while comfort keeps falling
- Clicking and failed ignition attempts before the furnace gives up
- The system starting and stopping every few minutes without warming the house
- Uneven heat, with certain rooms that never warm up
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. If you notice any of these signs, call (925) 205-6535 for a prompt inspection.
