We Know
Manchester Homes.
Manchester is NH's largest city and a big part of our service area. We have served homeowners throughout the city for many years.
Housing: The city has everything. Triple-deckers and older multifamily on the West Side and in the older mill-worker neighborhoods around the millyard, established colonials in the North End, 50s and 60s ranches and capes out toward the beltway, and newer construction near the highway corridors. The older neighborhoods tend to have more involved mechanical systems.
Heating: Oil boilers are very common in the older city neighborhoods. Many are cast iron systems that have run for 30 or 40 years. Boiler replacements are one of the most common jobs we do in Manchester.
Cooling: Most of the older homes in Manchester were heated with boilers, which means no ductwork. Mini splits are typically the cleanest way to add cooling and a backup heat source at the same time.
