Several factors affect the rental costs of diesel generators, including the generator's size, duration of hire, and any additional services such as delivery and setup. It's crucial to consider these elements when planning your rental to ensure you get the best value.
When renting a diesel generator, be aware of potential hidden fees. These can include delivery and pick-up charges, which may be flat rates or based on mileage. Fuel surcharges, damage waivers, and cleaning fees for returning the equipment in poor condition can also add to the total cost. Understanding these fees upfront can help you budget more accurately.
The demand for diesel generators in Phoenix is expected to remain strong in 2025, driven by construction projects and the need for reliable backup power. Rental companies are expanding their fleets to include more fuel-efficient and environmentally friendly models, which may influence rental pricing.
Ensure that any diesel generator you rent complies with local emissions regulations. Non-compliance can result in fines and additional costs, so it's essential to verify this with your rental provider.
