When the heat goes out in Mission, TX, 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 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.

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:
- Short cycling every few minutes while the house stays cold
- A furnace that tries to light, clicks, and then quits
- Strange smells from the vents, especially rotten egg or burning
- Booming or banging at ignition, a sign of delayed burner light-off
- A heat pump's outdoor unit encased in frost or ice
- Cold rooms in one part of the house while others are comfortable
- The thermostat calls for heat but the vents blow cold air or nothing
- Energy costs climbing even though the house feels colder
