The thing most pages get wrong

Southwest Gas's Arizona program does not pay for a new gas furnace or water heater in 2026: the residential form lists only showerheads, washers and windows. Check the current year's form before counting on a gas appliance rebate.

Lower incomes

Southwest Gas is one of the funders named on the Department of Housing's weatherization income chart, with APS and SRP; the state program is free below 200% of poverty.
