We Know
Manchester Homes.
Manchester is New Hampshire's largest city, with housing that changes from one neighborhood to the next. A.J. LeBlanc Heating serves older multi-family buildings near the river, single-family neighborhoods across the city, and newer homes along the outer corridors.
Housing: Manchester includes nearly every major housing type found in southern New Hampshire. Census data shows that most housing units are in multi-family buildings, including the triple-deckers and other older buildings found on the West Side and around the Millyard. About one-third of the city's housing predates 1940, and the median home dates to about 1966. The North End has established colonials, outer neighborhoods include many ranches and capes from the 1950s and 1960s, and newer construction is found closer to the highway corridors.
Furnaces, Boilers &
Heat Pumps
Heating in Manchester
Manchester's older neighborhoods include cast-iron, oil-fired boilers and other heating systems that have served their homes for decades. Liberty Utilities provides natural gas across much of the city, so A.J. LeBlanc Heating replaces gas furnaces and boilers and completes oil-to-gas conversions where service is available. We also work on oil and propane systems and install cold-climate heat pumps where they fit the home. Our recommendation accounts for the building's heating needs, piping or ductwork, chimney and venting, electrical capacity, and mechanical space.

Mini Split Installation
Cooling in Manchester
Many older Manchester homes were designed around boiler heat and have no central cooling ducts. Ductless equipment can provide room-by-room cooling with less disruption to plaster walls, and separate zones can work especially well in triple-deckers and other multi-family buildings. Homes with suitable forced-air ducts may be better candidates for central A/C or a ducted heat pump. A.J. LeBlanc Heating plans each system around the building layout, the number of living spaces, and the available electrical capacity.
Cooling Services We Provide
We install, repair, and service all types of cooling equipment in Manchester, including central air, heat pumps, and ductless mini splits. With thousands of ductless installations completed across Southern NH, our team has extensive experience. We respond quickly when you need a repair or replacement.

Filtration, Softeners

Water Treatment in Manchester
Manchester Water Works supplies most city homes, drawing mainly from Lake Massabesic with a radial collector well beside the Merrimack River as a supplemental source. The utility uses treatment processes that include ozone and carbon filtration and maintains chloramine in the distribution system. Because the finished water is classified as soft, most Manchester homes do not need a water softener.
A.J. LeBlanc Heating can install activated-carbon equipment sized to reduce an unwanted taste or odor, along with under-sink carbon or reverse osmosis systems for drinking and cooking water. If the concern is limited to one faucet, we first check the fixture and nearby plumbing so the recommendation addresses the actual problem.
Water Treatment Services We Provide
Our team installs and services water-treatment equipment for Manchester homes. We use independent laboratory results for private wells and the utility report and condition at the tap for public-water homes.
- Well Water Filtration
- Water Softeners
- Iron & Manganese Removal
- Reverse Osmosis Drinking Water
- UV Purification
- Water Sampling & Independent Laboratory Testing

Plumbing in Manchester
Manchester's older homes and multi-family buildings can have compact utility spaces, aging shutoff valves, and drain piping that has been altered over the years. A.J. LeBlanc Heating repairs faucets, toilets, leaks, supply piping, household drains, and water heaters throughout the city. We also replace deteriorated cast-iron drain sections when corrosion, cracking, or recurring backups show that the pipe itself is failing.
In multi-family properties, we plan access and shutoffs carefully so the repair is clear and disruption is kept to a minimum.
