Propane, Compressed Gas & Dry Ice Supplier in Chester, CT

Tucked into the hillside above the Connecticut River about ten miles north of Long Island Sound, Chester is the kind of small Connecticut town that earns its “quaint and unique” reputation without having to try. The village center, where Main, Spring, and River streets converge at a tight curve, holds a mix of art galleries, locally owned restaurants, and shops that draw visitors from well beyond Middlesex County. In fact, the 1769 Chester-Hadlyme Ferry still carries passengers across the Connecticut River to Gillette Castle, one of the more quietly remarkable pieces of local character still operating in the state.
As a fourth-generation family business serving Connecticut since 1941, ALL-GAS is proud to support Chester homeowners and businesses. The town’s hillside setting, its wooded residential roads, and its distance from municipal gas infrastructure make propane a natural fit here. Whether you heat a historic colonial on a back road, run a business along Main Street, or manage a property near the river, we deliver reliable service and expert support year-round.
Services & Products We Provide
Residential Propane in Chester, CT
Chester’s residential character is a mix of village-center homes within walking distance of Main Street and properties spread along wooded, hilly roads where natural gas lines simply don’t reach. For those households, propane handles everything from whole-home heating and hot water to kitchen appliances, fireplaces, and standby generators that keep the lights on when storms roll through. At ALL-GAS, we handle installations on challenging terrain and provide automatic delivery so you don’t have to track your tank through a Connecticut winter.
Whether your home sits near the village green, along a quiet road above the river valley, or at the edge of Cockaponset forest, our team keeps your supply steady. Our residential propane services include:
