We Know
Chester Homes.
Chester has retained its working-farm character even as its population grew from about 860 residents in 1900 to just over 5,200 in 2020. A.J. LeBlanc Heating serves older properties around the Route 121 and 102 town center and newer homes on larger lots throughout the community.
Housing: Nearly every Chester housing unit is an owner-occupied, single-family home. The median house dates to about 1991, and many properties were built during the 1990s and 2000s. Pre-1940 farmhouses and colonials remain in older areas, while ranches and split-levels from the 1970s and 1980s add another layer to the housing stock. Large lots and newer, larger homes can require careful zoning and equipment placement.
Furnaces, Boilers &
Heat Pumps
Heating in Chester
Oil is Chester's most common heating fuel, with propane also used in a town that has no natural gas service. A.J. LeBlanc Heating services and replaces oil and propane boilers and furnaces in older farmhouses, ranches, split-levels, and newer homes. Boiler systems may require evaluation of the baseboard or radiators and piping, while larger forced-air homes need airflow and zoning considered. Cold-climate heat pumps provide another option for homeowners who want to reduce delivered-fuel use.
Heating Services We Provide
Chester homeowners can call us for heating installation, repairs, and annual service. We also replace complete heating systems and respond quickly when something goes wrong.

Air Conditioning &
Mini Split Installation
Cooling in Chester
Many older Chester homes use boiler heat and lack ductwork for central air conditioning. A multi-zone mini split system can add cooling to larger floor plans without opening finished walls for new ducts. Homes with suitable forced-air ductwork may be better candidates for central A/C or a ducted heat pump. A.J. LeBlanc Heating measures the home and sizes the system to its actual layout instead of relying on a rule of thumb.
Cooling Services We Provide
We install, repair, and service all types of cooling equipment in Chester, 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
& Testing
Water Treatment in Chester
Chester relies on groundwater from private wells and smaller regulated public-water systems. Nearby wells can have different chemistry, so private-well treatment begins with testing at the property, while regulated-system customers begin with their provider's report. A.J. LeBlanc Heating submits collected private-well samples to an independent laboratory and matches equipment to confirmed results or a specific taste, odor, staining, or scale concern.
Options may include sediment, iron, manganese, hardness, sulfur-odor, ultraviolet, or arsenic treatment. For confirmed radon in well water, we can recommend an independent mitigation company for the homeowner to contact. Regulated-system customers may choose whole-house carbon or a dedicated drinking-water system for a specific goal.
Water Treatment Services We Provide
Our team installs and services water-treatment equipment for Chester homes. We use independent laboratory results for private wells and the utility report and condition at the tap for public-water homes.

- Water Softeners
- Iron & Manganese Removal
