AC Maintenance in Norman, OK: Signs of Wear and What to Watch For

If you’re a homeowner in Norman, OK, routine AC maintenance is key to catching small issues before they become major problems. On a recent service call, our technician inspected two systems and uncovered several warning signs that indicate the west unit is nearing the end of its service life.
🔍 What We Found:
While both systems were operational, the west unit raised several red flags:
- The blower wheel was extremely dirty, which can restrict airflow and strain the system.
- The blower capacitor was testing out of range—an early warning that the motor could soon fail.
- We found significant rust in the burner compartment, indicating long-term moisture exposure.
- The condenser fan motor had play in the shaft, which will eventually lead to failure.
- The condenser fan capacitor was also out of range and should be replaced.
Despite these issues, the system was still running—but not as efficiently or reliably as it should.
✅ What We Did:
- Changed all system filters
- Cleared both condensate drain lines to prevent backups
- Washed both outdoor units to restore cooling efficiency
- Checked refrigerant pressures for both systems
- Documented all findings and emailed estimates to the customer
The homeowner opted to hold off on major repairs for now, but we’ve given them the information needed to make an informed decision when they’re ready.
