HVAC Repair Costs in 2026
Common Repairs
- Capacitor replacement: $150-$300 — causes AC to not start or cycle frequently
- Blower motor: $300-$600 — causes weak or no airflow
- Refrigerant recharge: $200-$500 — indicates a leak that should also be repaired
- Ignitor/pilot: $150-$300 — furnace won't ignite
- Thermostat replacement: $100-$350 — system won't respond to temperature settings
- Contactor: $150-$300 — AC won't turn on
- Fan motor: $200-$450 — outdoor unit fan not spinning
Major Repairs
- Compressor replacement: $1,500-$2,500 — often more cost-effective to replace the entire AC unit
- Heat exchanger: $500-$1,500 — cracked exchanger is a safety hazard (CO risk)
- Evaporator coil: $600-$2,000 — frozen or leaking coil
- Condenser coil: $400-$1,200 — outdoor unit not cooling
Repair vs Replace Rule
If the repair costs more than 50% of a new system AND the system is over 10 years old, replacement is usually the better investment. New systems are 30-50% more efficient, which reduces monthly bills.
Related Questions
How do I know if my HVAC needs repair?
Warning signs: unusual noises (banging, squealing, clicking), weak airflow, warm air from AC, short cycling (frequent on/off), higher than normal energy bills, uneven temperatures, and strange smells (musty, burning, rotten eggs).
Can I repair my own HVAC system?
Simple tasks like changing filters, cleaning outdoor units, and resetting breakers are DIY-safe. Anything involving refrigerant, electrical components, or gas lines requires a licensed HVAC technician — both for safety and to maintain warranty.
Does home warranty cover HVAC repair?
Most home warranties cover HVAC systems, but with limitations: pre-existing conditions may be excluded, coverage caps ($1,500-$3,000) may not cover full replacement, and you must use their contractor. Read your contract carefully.
