- Insist on a Manual J load calc — oversizing wastes money
- Buy in the off-season (spring or fall) for better pricing
- Check manufacturer and utility rebates (federal 25C credit ended 2025)
- Past ~12–15 years, replacing usually beats repeated repairs
- Bundle AC and furnace replacement to save on labor
