When the heat goes out in Fullerton, CA, the clock starts running, 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 buried under frost, 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.
Most of our service calls are for Furnace Repair. Start there if your system isn't running right.
Warning Signs for Heating Repair
Recognizing the warning signs early can save you time and money. Here are the most common indicators that it's time to call a professional:
- Clicking and failed ignition attempts before the furnace gives up
- Some rooms warm while others stay stubbornly cold
- Heating bills spiking while comfort keeps falling
- No warm air at the registers even with the heat turned up
- A loud boom when the burners light, which points to delayed ignition
- The system starting and stopping every few minutes without warming the house
- A heat pump's outdoor unit encased in frost or ice
- A rotten-egg, burning, or musty smell once the heat kicks on
