Why Your Heat Works But Your AC Doesn’t
If your furnace runs fine but your air conditioner won’t cool, you’re dealing with a cooling-side failure, not a full system failure.
Heating and cooling share ductwork — but they operate independently.
This is extremely common in:
- Oklahoma City
- Moore
- Norman
Top Causes
1. Outdoor Unit Not Running
If the condenser outside isn’t turning on, AC won’t cool.
- Bad capacitor
- Contactor failure
- Electrical issue
2. Refrigerant Leak
System runs but blows warm air.
3. Frozen Evaporator Coil
Airflow restriction or low refrigerant.
4. Thermostat Wiring Issue
Heating wire (W) works. Cooling wire (Y) not signaling properly.
Why This Requires Expert AC Service
This is not a DIY diagnosis.
An expert AC service technician will:
- Check refrigerant pressure
- Test capacitor and contactor
- Inspect evaporator coil
- Verify thermostat voltage
- Confirm compressor function

Repair vs Replacement?
- System is 12–15+ years old
- Compressor failed
- Refrigerant is R-22
- Repairs exceed 40% of replacement cost
Then AC installation becomes smarter long-term.
