On average, a gas grill can last from five to 15 years. The exact lifespan depends on several factors, including the brand and quality of the grill, frequency of use, and whether the gas line is buried or above ground. With proper maintenance and care, such as regular deep cleanings to remove food, grease, and carbon deposits, a grill's life can be extended. Protecting the grill from the elements with a cover can also prevent rust and reduce the need for repairs. Most grill manufacturers also offer extended warranties, which vary in coverage and terms.

Local codes often mandate specific fittings, permits, and vent considerations for permitted function and safety, which are enforced by professionals.

The most significant benefit of having a gas grill over a propane grill is that you never run out of fuel unless there’s an outage in your area, which is rare. Unlike with a propane grill, you’ll never need to haul tanks back and forth to a local fill station, and you’ll never find yourself unable to use your grill because you forgot to refill your tanks. Gas grills also burn slightly cleaner than propane grills, and natural gas costs significantly less than propane, meaning it’s more affordable to run your grill.

Gas grill installation costs around $540 on average, not including the price of the actual grill, and most homeowners pay between $120 and $1,400. This total will go toward laying down a new gas line, connecting it to your existing gas system, pressure testing the line, and connecting it to your grill. Your total project price will depend on the length of the gas line, whether or not the line needs to be installed underground, and the cost of the permits in your area.
