Furnace repair costs
Common furnace repairs in Kansas City, like igniter or flame sensor replacement, run $150-$350. Bigger repairs such as a failing heat exchanger or blower motor can run $500-$1,500, and a cracked heat exchanger often means replacement is the safer call.
Winter cold snaps in Kansas City push furnaces hard, so an annual fall tune-up (typically $100-$150) catches minor issues before a January breakdown.
AC repair costs
AC repairs range from $150 for a simple capacitor swap up to $1,200+ for refrigerant leak repairs. A failing compressor can push repair costs above $2,000, at which point comparing to full replacement makes sense on older units.
Ductwork and airflow repairs
Many Kansas City homes, especially older bungalows and ranches, have ductwork that's undersized or leaking. Duct sealing and minor repairs run $400-$2,200 depending on how much of the system needs work.
Poor airflow is a common complaint in homes with original 1950s-60s ductwork paired with newer, higher-efficiency equipment, so it's worth having a contractor evaluate the full duct system, not just the equipment.
When repair costs point to replacement
As a general rule, if a single repair quote is more than 30-50% of a replacement system's cost on a unit already 12+ years old, most Kansas City contractors will recommend replacement instead, particularly with the ongoing shift from R-410A to R-454B making some older refrigerant hard to source.
Typical cost ranges
| Furnace igniter or flame sensor repair | $150 - $350 |
| Furnace blower motor repair | $500 - $1,500 |
| AC capacitor/contactor repair | $150 - $400 |
| AC refrigerant leak repair | $300 - $1,200 |
| Ductwork repair/sealing | $400 - $2,200 |
| Annual tune-up (furnace or AC) | $100 - $200 |

Common questions
What's the average HVAC repair cost in Kansas City?
Most single repairs fall between $150 and $650, though major component failures like a compressor or heat exchanger can run $1,000-$2,500.
Is furnace repair cheaper than AC repair?
They're similar for common issues like sensors or capacitors, but major furnace repairs like heat exchangers tend to be pricier than most AC component repairs.
Why is ductwork repair sometimes needed with HVAC repairs?
Many Kansas City homes have original ductwork that's undersized or leaking, which can cause uneven heating and cooling even after equipment repairs, especially in older neighborhoods.
Should I repair or replace an old furnace?
If your furnace is 15+ years old and the repair quote is high relative to a new unit's cost, most Kansas City contractors recommend replacement, especially heading into another cold winter.
Do repair costs include the service call fee?
Usually a diagnostic or service call fee ($75-$150) is separate and is often credited toward the repair cost if you move forward with the same company.
