Nashua's urban residential core—notably the Tree Streets (Ash, Elm, Chestnut, Walnut) and French Hill—is densely populated with pre-1940 two-family and three-family multi-family properties. Most of these historic homes are heated by natural gas or oil-fired cast-iron boilers, with a substantial percentage still relying on single-pipe low-pressure steam radiators.

Manchester's architectural legacy is defined by the Amoskeag Manufacturing Company's historic expansion, leaving thousands of multi-family triple-deckers across the West Side, Rimmon Heights, and Center City, as well as grand Victorian estates in the North End.

Many of Bedford's premier neighborhoods—surrounding Pulpit Rock Conservation Area, Joppa Hill Road, and Back River Road—feature 3,500 to 6,000+ square-foot executive colonials built from the 1980s through the 2000s. Because municipal natural gas mains do not extend to these sprawling wooded subdivisions, properties rely on large 500-to-1,000-gallon underground propane tanks.

A large proportion of Hudson's single-family homes—particularly in the neighborhoods surrounding Benson Park, Robinson Pond, and along the Route 102 and Route 111 corridors—were constructed during the suburban boom of the late 1970s, 1980s, and 1990s. Many of these split-levels, raised ranches, and traditional capes still house their original 80% AFUE natural gas furnaces and legacy 10 SEER central air conditioners.

Litchfield's landscape is characterized by fertile agricultural soils, active farm stands, and single-family colonials and ranches built from the 1980s through the 2000s along the Route 3A corridor.
