It's July. Your AC Just Died. The Emergency Tech Charges $400/Hour.
Friday afternoon. 94 degrees outside. Your HVAC compressor just failed. The emergency tech can come — but it's $400/hour plus parts. That $40 filter change you skipped in April? It just became a $3,000 repair.
The Preventive Maintenance Schedule
| Frequency | Tasks |
|---|---|
| Monthly | Replace or clean filters, check thermostat calibration, inspect drain lines |
| Quarterly | Clean coils, check refrigerant levels, lubricate moving parts, inspect belts |
| Semi-annually | Full system inspection, duct inspection, test safety controls |
| Annually | Full clean and tune-up, efficiency testing, replace worn components |
What You Save
| Scenario | Annual Cost |
|---|---|
| Reactive only (no maintenance) | $4,500-$12,000+ |
| Preventive maintenance contract | $1,200-$3,000 |
| Net savings | $3,300-$9,000 |
Plus, well-maintained systems use 15-25% less energy. On a commercial system, that's $200-$800/month.
Red Flags Your System Needs Attention
- Uneven temperatures between zones
- Unusual noises during startup
- Higher-than-normal energy bills
- Musty smells when the system runs
- System cycling on and off frequently
