Furnace Repair in San Antonio, TX | Gas & Electric Furnace Service

Most furnace repairs range from $150 to $800, depending on the issue. Simple fixes like thermostat problems or dirty filters cost $150–$300. Component replacements (ignitor, flame sensor, blower motor) run $200–$600. Major repairs (heat exchanger, gas valve) can reach $800–$1,500. We provide upfront pricing before any work begins, and all repairs include our 1-year warranty.

Consider replacement if your furnace is over 15 years old, requires frequent repairs, has a cracked heat exchanger, or repair costs exceed 50% of replacement value. Repair makes sense for newer systems (under 10 years), single component failures, and when the furnace has been well-maintained. We'll give you honest guidance based on your specific situation.

Yes! We provide emergency furnace repair throughout San Antonio. When your heat goes out on a cold night, call (210) 555-0199 for same-day service. We prioritize heating emergencies, especially for families with young children or elderly residents.

The most common issues we see are: faulty igniters (won't start), dirty flame sensors (cycles on/off), clogged filters (poor airflow), thermostat problems (won't respond), blower motor failure (no air movement), and cracked heat exchangers (safety hazard). Many of these can be prevented with annual maintenance.

Most furnace repairs take 1–3 hours. Simple fixes (thermostat, filter, flame sensor cleaning) take 30–60 minutes. Component replacements (ignitor, blower motor, capacitor) take 1–2 hours. Complex repairs (gas valve, heat exchanger inspection) may take 2–3 hours. We'll give you an accurate time estimate before starting work.

If your furnace is still under manufacturer warranty (typically 5–10 years on parts), the part may be covered. However, labor is usually not included. All Yeti repairs come with our 1-year warranty covering both parts and labor, giving you peace of mind beyond the manufacturer's coverage.

Our warranty covers all parts and labor for one full year from the repair date. If the same issue returns or the repaired component fails, we'll fix it at no additional charge. This includes free return visits and any necessary replacement parts (excluding damage from external causes like power surges or flooding).
