Not sure if you need a full replacement or just a repair? At 1CoolAir, we never upsell. We’ll assess your system and give you straight advice.
| Consider Replacement If… | Repair May Be Fine If… |
|---|---|
| Your unit is 12–15+ years old | The system is under 10 years old |
| Repair costs exceed 50% of a new unit | It’s a minor, one-time fix |
| Monthly energy bills keep rising | The unit still cools/heats efficiently |
| Frequent breakdowns are happening | Problems are rare and isolated |
| Your home has uneven temperatures | Overall comfort is still good |
