What to check first
- Confirm who supplies, installs and warrants the system
- Verify current product documents directly
- Compare written service and financial terms with alternatives
Verify the current contractual chain
A recognizable brand does not by itself establish who will install the equipment, honor the warranty or provide service. Obtain current documents and identify the legal entities accepting each obligation.
Review the equipment model, warranty exclusions and process for making a claim. Compare the full proposal with alternatives using the same consumption and site assumptions. Avoid making a purchase decision from historical brand reputation or an unsupported claim about the best time to invest.
