Furnace Types: Gas vs Electric
Gas Furnaces — The most common furnace type in Central Texas. Burns natural gas to produce heat.
| Feature | Standard Efficiency | High Efficiency |
|---|---|---|
| AFUE Rating | 80% | 90-98% |
| Typical Cost (Installed) | $3,000 - $5,000 | $4,500 - $8,000 |
| Annual Operating Cost | Higher | 15-30% lower |
| Venting | Standard metal flue | PVC pipe (can vent sidewall) |
| Best For | Budget-conscious, existing infrastructure | Long-term savings, new construction |
Electric Furnaces — Uses electric heating elements instead of gas burners. Simpler design with fewer components.
| Feature | Electric Furnace |
|---|---|
| Efficiency | Nearly 100% (all electricity becomes heat) |
| Typical Cost (Installed) | $2,000 - $4,500 |
| Operating Cost | Higher than gas (electricity costs more per BTU) |
| Safety | No combustion gases, no carbon monoxide risk |
| Best For | Homes without gas lines, mild climates |
Heat Pumps — An alternative to furnaces that provides both heating and cooling. Highly efficient in mild climates like Central Texas. Learn about heat pump services. Heat pump vs furnace comparison.

Signs Your Furnace Needs Repair
Do not wait for a complete breakdown during a cold snap. Watch for these warning signs:
- Furnace not turning on — Check the thermostat, batteries, and circuit breaker first. If those are fine, the ignitor, control board, or gas valve may have failed. Furnace not turning on troubleshooting guide.
- Blowing cold air — If your furnace runs but the air is not warm, the problem could be a failed ignitor, a bad flame sensor, or thermostat settings. Furnace blowing cold air guide.
- Strange noises — Banging (delayed ignition), squealing (blower motor bearings), rumbling (dirty burners), or clicking (ignitor issues) all indicate specific problems.
- Yellow or flickering pilot flame — A healthy furnace flame is steady and blue. A yellow or flickering flame indicates incomplete combustion and possible carbon monoxide production.
- Frequent cycling — The furnace turns on and off every few minutes without reaching the set temperature. Usually caused by a dirty filter, bad thermostat, or overheating.
- Rising gas or electric bills — A sudden increase in heating costs means your furnace is losing efficiency.
- Burning or musty odors — A burning smell on first use of the season is normal (dust burning off). Persistent burning smells or musty odors require investigation.
- Carbon monoxide detector alarm — Evacuate your home immediately and call 911. A furnace can produce carbon monoxide from a cracked heat exchanger or improper venting.
- Age of furnace — Furnaces typically last 15-20 years. If yours is over 15 and needing repairs, replacement may be more cost-effective. How long does a furnace last?

Furnace Safety Information
Gas furnaces are safe when properly installed and maintained, but they do produce combustion gases that must be vented correctly. Here are essential safety tips:
- Install carbon monoxide detectors on every level of your home, especially near bedrooms. Test them monthly and replace batteries annually.
- Never block furnace vents or air returns — Restricted airflow causes overheating and can crack the heat exchanger.
- Keep the area around your furnace clear — At least 3 feet of clearance. No storage, no flammable materials.
- Change your air filter regularly — Every 1-3 months. A clogged filter is the number one cause of furnace problems. How to change your furnace filter.
- Schedule annual maintenance — Professional inspection catches cracked heat exchangers, gas leaks, and carbon monoxide risks before they become dangerous. Maintenance plans.
- Know the signs of carbon monoxide — Headaches, dizziness, nausea, confusion. If your CO detector alarms or you experience these symptoms, evacuate and call 911.
Furnace Maintenance

Furnace Repair vs Replacement: When to Replace
Use this guideline to decide between repair and replacement:
Repair if:
- Furnace is under 12 years old
- This is the first or second repair
- Repair cost is less than one-third the cost of a new furnace
- No safety issues (heat exchanger is intact)
Replace if:
- Furnace is 15-20+ years old
- Repair cost exceeds half the cost of a new furnace
- Heat exchanger is cracked (safety hazard)
- Multiple breakdowns per season
- Energy bills are steadily rising despite maintenance
- Furnace uses R-22 refrigerant (if it is a heat pump)
- Parts are discontinued or hard to find
Use our Repair or Replace Calculator to run the numbers. Check your furnace’s age with our HVAC Age Decoder.

Frequently Asked Questions About Furnace Repair
How much does furnace repair cost in Killeen, TX?
Most furnace repairs in Killeen and Central Texas cost between $150 and $700. A diagnostic service call is $75-$150. Common repairs like an ignitor or flame sensor replacement cost $150-$350. Major repairs like a blower motor replacement run $300-$700, and heat exchanger replacement costs $1,000-$3,000. We provide upfront pricing before starting any work.
How long does furnace repair take?
Most furnace repairs are completed in 1-2 hours during a single visit. Our trucks carry the most common parts including ignitors, flame sensors, capacitors, and thermostats. Heat exchanger replacement or complete system replacement takes longer — typically 4-8 hours.
Why is my furnace blowing cold air?
The most common causes are a failed ignitor (furnace cannot light the burners), a dirty flame sensor (furnace lights but shuts off within seconds), incorrect thermostat settings (check that it is set to “heat” and “auto”), or a clogged air filter causing the furnace to overheat and shut down. Read our full troubleshooting guide.
How long does a furnace last?
A well-maintained gas furnace typically lasts 15-20 years. Electric furnaces can last 20-30 years due to fewer mechanical components. Without regular maintenance, lifespan drops significantly. Read our complete guide: How long does a furnace last?
Should I repair or replace my furnace?
As a rule of thumb, if your furnace is over 15 years old and the repair costs more than half the price of a new furnace, replacement is usually the better investment. A new high-efficiency furnace can reduce heating costs by 15-30% compared to an older model. Use our Repair or Replace Calculator to compare costs for your specific situation.
Is a gas or electric furnace better for Texas?
For most Central Texas homes with natural gas service, a gas furnace is the more economical choice because natural gas costs less per BTU than electricity. However, if your home does not have a gas line, an electric furnace or heat pump is the better option. Heat pumps are particularly well-suited to Texas because they provide both heating and cooling efficiently in our mild climate. Gas vs electric furnace comparison | Heat pump vs furnace comparison.
How often should I change my furnace filter?
Standard 1-inch filters should be changed every 1-3 months. If you have pets, allergies, or live in a dusty area, change it monthly. Thicker 4-5 inch media filters last 6-12 months. A clean filter is the single most important thing you can do to prevent furnace problems and maintain efficiency. How to change your furnace filter.
