Signs Your Furnace Needs Repair
Recognizing the early warning signs of furnace failure can be the difference between a simple fix and a dangerous mid-winter breakdown. If you notice your system is 'short cycling'—turning on and off frequently—or if your utility bills have skyrocketed despite no change in usage, your heater is likely struggling with a mechanical inefficiency. Be particularly alert for unusual sounds like banging, whistling, or screeching, as well as any persistent odors or a pilot light that has turned from a steady blue to a flickering yellow. Addressing these red flags early not only restores your comfort but also prevents potential safety hazards like carbon monoxide leaks or electrical fires.
Signs Include:
Blowing Cold Air: Your system is running, but the air coming from the vents isn't getting warm.
Strange Noises: Banging, whistling, or rattling sounds coming from the furnace cabinet.
Frequent Cycling: The heater turns on and off constantly without reaching the set temperature.
Odd Smells: A persistent burning smell or the scent of rotten eggs (signaling a possible gas leak).
Pilot Light Issues: A yellow or flickering pilot light instead of a steady blue flame.

Why is my furnace blowing cold air?
This is often caused by a dirty air filter, a faulty thermocouple, or a pilot light that has gone out. We recommend checking your filter first; if the issue persists, call us for a diagnostic.
How much does furnace repair cost in New Braunfels?
Costs vary depending on the part needed. We charge a flat-rate diagnostic fee to find the problem and provide a transparent, upfront quote before any work begins.
Is it safe to run my furnace if I smell gas?
No. If you smell a "rotten egg" odor, turn off the gas line, exit your home immediately, and contact the gas company and Centeno Air for an emergency inspection.
How long does a furnace usually last in Texas?
In our climate, a well-maintained furnace can last 15–20 years. However, if your unit is over 15 years old and needs frequent repairs, a replacement may be more cost-effective.
Do you offer 24/7 emergency heating repair?
Yes. We understand that heating failures during a freeze are an emergency. Our team is available 24/7 to restore warmth to your New Braunfels home.
Can a dirty filter cause my heater to stop working?
Yes. A clogged filter restricts airflow, causing the furnace to overheat and trigger a safety "limit switch" that shuts the system down.
