Heat pump or furnace? That is the first thing that matters when the heat quits in Laredo, TX, because the two fail in completely different ways. Heat pumps tend to freeze up when defrost stops working, get stuck in cooling when a reversing valve fails, or quietly lean on the electric backup strips, at several times the normal operating cost, when the outdoor unit dies. Gas furnaces typically come down to the flame sensor: once oxide coats it, the burners light but the flame cannot be proven, so the board cuts the gas and locks out after three tries. After that, we most often find cracked hot surface igniters, stuck pressure switches, clogged condensate traps on high-efficiency models, and blower motors at the end of their life.
Most of our service calls are for Furnace Repair. If something has stopped working, start there.
When to Call for Heating Repair in Laredo
Spotting the early warning signs lets you act before the problem gets expensive. Watch for these telltale signs:
- An outdoor heat pump coil that stays iced over
- Some rooms warm while others stay stubbornly cold
- Burning, musty, or rotten-egg odors when the heat runs
- The thermostat calls for heat but the vents blow cold air or nothing
- A loud boom when the burners light, which points to delayed ignition
- Heating bills spiking while comfort keeps falling
- A furnace that tries to light, clicks, and then quits
- Frequent on-off cycles that never bring rooms up to temperature
