COSMO COS-244AGC 24-Inch Gas Range

In this cosmo cos-244agc 24-inch gas range review, the verdict is simple: the COSMO COS-244AGC is the narrow-space pick in our best gas ranges guide for 2026, ranked seventh of seven overall but first for kitchens whose opening measures 23.6 inches wide. The COSMO COS-244AGC sells for $1,074.99 and holds a 3.6-star average from 24 Amazon ratings. It packs a 2.7 cu ft convection oven and four sealed burners, including a 17,400 BTU rapid burner, into a stainless steel slide-in body that measures 23.6 inches wide, 23.6 inches deep, and 35.5 inches tall. It weighs 132 pounds. Buy it only when a 24-inch cutout is your hard limit; shoppers with 30 inches of space should look at the larger GE model in our guide.

In practice, the COSMO COS-244AGC spreads 17,400 BTU at its rapid burner for searing and boiling, two 6,900 BTU burners for everyday pans, and a 5,000 BTU auxiliary burner for sauces that would scorch over high heat. Sealed burners keep spills on the surface instead of inside the chassis, and the cast iron grates hold heat well and lift out for cleaning. Inside, Rapid Convection moves hot air around the 2.7 cu ft cavity, so cookies and sheet-pan dinners brown more evenly and finish faster than in a standard oven. Two racks, a digital display with timer, metal knobs, a storage drawer, and a wok grate attachment round out the package. On top of that, the brushed 403-grade stainless steel resists corrosion, and the range ships set for natural gas with liquid propane conversion available. It draws 120 volts and 9 amps through a standard 3-prong plug.

By contrast with the bigger ranges higher in our guide, the COSMO COS-244AGC costs $1,074.99, and its 3.6-star rating comes from only 24 Amazon ratings, a small sample that leaves long-term reliability unproven. Meanwhile, the 2.7 cu ft oven holds about one sheet pan at a time, and installation demands a precise slide-in cutout plus roughly 35.5 inches of height clearance. Even so, few 24-inch ranges combine convection, four sealed burners, and a 17,400 BTU burner at any price. If your kitchen cannot fit a 30-inch range, this is the one to get.
