Two autogas quotations can have the same headline price but cover different equipment, cylinder arrangements, testing and aftercare. When comparing LPG or CNG installation in Gyumri, request a complete written scope rather than choosing by system name alone.
Give every installer the same make, model, year, engine information and current vehicle condition. Confirm whether each proposal is LPG or CNG and whether the package is assessed for that engine. Existing running faults should be uated before conversion.
Do not compare a parts-only figure with a finished installation.
Ask to see the intended location before approval. Consider luggage volume, spare-wheel access, loading and how trim will be refitted. The installer should explain the proposed arrangement for the specific vehicle without unsupported promises about range or consumption.
Vehicle and engine, fuel type, component specification, cylinder choice, mounting work, existing faults and included documentation all matter. Ask which findings could require a revised price and approve changes before they are made. Also clarify what first check and later servicing are included.
Use an appropriately competent installer and confirm current Armenian inspection, registration and documentation requirements. At handover, have the installer demonstrate switching and operation, verify there is no gas odor or new warning, and receive component and service records. With suspected leakage or gas odor, stop using the gas system, avoid ignition sources and seek professional help.
