We Know
Exeter Homes.
Founded in 1638, Exeter combines a historic Seacoast center with postwar neighborhoods and newer development toward the town's edges. Brick and clapboard homes from the 1700s and 1800s remain near Phillips Exeter Academy and downtown. A.J. LeBlanc Heating serves those historic houses, multi-family buildings, manufactured homes, and later single-family properties.
Housing: Exeter has a more varied housing mix than a typical suburb. Single-family homes account for just under half of its units, multi-family buildings make up close to 40 percent, and manufactured homes account for another 12 percent. Nearly one-quarter of the housing predates 1940, while construction also peaked during the 1970s and 1980s, putting the median build year near 1979. The oldest houses near Phillips Exeter Academy and downtown require particular care around original finishes and systems added over generations.
Heating: Exeter homes use natural gas, oil, propane, and heat pumps. Unitil provides natural gas in parts of town, allowing A.J. LeBlanc Heating to complete gas replacements and oil-to-gas conversions where service is available at the address. Many older homes still have oil-fired steam or hot-water systems that require experience with the boiler, piping, radiators, venting, and controls. In multi-family buildings, we also determine whether one system serves several units and plan zoning, access, and replacement around that layout.
Cooling: Older Exeter homes near downtown often have boiler heat and no ductwork for central air conditioning. A mini split system can provide zoned cooling with limited disruption to original plaster and woodwork, and it can also serve individual spaces in multi-family buildings. Postwar and newer homes with suitable forced-air ducts may be suited to central A/C or a ducted heat pump. A.J. LeBlanc Heating evaluates the home's layout, existing system, and electrical capacity before recommending equipment.

What Southern NH
Homeowners Say
"I found LeBlanc to be a friendly company. When I called, I was greeted by the office staff who scheduled my appointment for a yearly cleaning. Three days later the technician came over and cleaned the system. He did a great job like no one else has ever done before. He also checked the system for proper performance. I was very happy with his work and would recommend A.J. LeBlanc HVAC to anyone who is looking for a GOOD firm to service their systems. I would also recommend them for any new installation I guarantee that they will get reliable service."
