Signs Your Furnace Needs Repair in Round Rock, TX

Do not wait for a complete shutdown to call for service. These symptoms mean your furnace needs professional attention now:

Furnace blowing cold air in Round Rock

The most common complaint. Usually caused by a failed ignitor, a dirty flame sensor, a tripped limit switch, or a gas supply interruption.

Furnace not turning on at all

If your thermostat calls for heat and nothing happens, the problem is typically in the ignition system, the control board, or the thermostat itself.

Furnace making a banging noise in Round Rock

A loud bang or boom when the furnace starts is a classic sign of delayed ignition — unburned gas igniting in a flash. This needs immediate attention.

Furnace pilot light out

On older standing-pilot furnaces, a pilot that will not stay lit usually points to a failing thermocouple. On modern systems, it is typically the ignitor or gas valve.

Short-cycling furnace

Starts, runs for a few minutes, shuts off, restarts. Almost always caused by overheating due to a clogged filter, blocked vents, or a failing heat exchanger.

Yellow or orange pilot flame instead of blue

A healthy furnace flame is blue. Yellow or orange flames indicate incomplete combustion — potentially a carbon monoxide risk.

Gas smell when furnace runs

A faint gas smell at startup is common, but a persistent smell means you should turn off the furnace, leave the house, and call us at (512) 690-7796 immediately.
