Hartford's natural gas distribution system includes cast iron mains installed in the 1940s and 1950s that still serve neighborhoods like Barry Square and Behind the Rocks. While Eversource has replaced many of these lines, thousands of homes still connect to aging infrastructure that experiences pressure fluctuations during peak winter demand. When gas pressure drops below 7 inches of water column during cold snaps, your furnace's gas valve may not seat properly when the heating cycle ends, allowing small amounts of gas to seep into the cabinet. Over time, this repeated stress causes valve seats to wear and O-rings to fail, creating the conditions for emergency furnace gas leak service calls. We test incoming gas pressure on every service call and document when utility supply issues contribute to furnace problems.
