We Know
Brentwood Homes.
Brentwood is a primarily residential Rockingham County community between the Seacoast and the state's interior, crossed by the Exeter River and its tributaries. A.J. LeBlanc Heating serves older farmhouses and newer single-family homes throughout this county-seat town.
Housing: Most Brentwood housing consists of owner-occupied, single-family homes, with only a small multi-family share. Substantial development occurred from 1990 through 2009, and the median home dates to about 1995. Older farmhouses and pre-1940 houses remain among the newer neighborhoods. Natural gas reaches only limited corridors, so oil and propane remain common across much of town.
Furnaces, Boilers &
Heat Pumps
Heating in Brentwood
Oil and propane heat many Brentwood homes. Unitil provides natural gas along limited corridors, including Route 27, with availability confirmed for each address. A.J. LeBlanc Heating services and replaces oil and propane boilers and furnaces in newer homes and older farmhouses and works on gas equipment where utility service is available. We help homeowners compare staying with the current fuel, completing an oil-to-gas conversion, or installing a cold-climate heat pump based on the home, ductwork or piping, electrical capacity, and available utilities.

Brentwood 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 Brentwood
Many newer Brentwood homes have forced-air ductwork that may accommodate central A/C or a ducted heat pump after airflow and capacity are verified. Older farmhouses with boiler heat may be better suited to a mini split system. Either type of heat pump can provide summer cooling and reduce oil or propane use during milder weather. A.J. LeBlanc Heating sizes the system to the home and the rooms it needs to serve.
Cooling Services We Provide
We install, repair, and service all types of cooling equipment in Brentwood, 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 Brentwood
Private wells are the main residential water source in Brentwood. The state included the town in a broader area targeted for arsenic and uranium testing, which supports testing for those contaminants but does not prove either is present in a particular well. A.J. LeBlanc Heating collects the water sample for independent laboratory analysis and uses a panel that also covers pH, hardness, staining conditions, odor, and other health-related contaminants.
Confirmed arsenic may lead to under-sink reverse osmosis or whole-house filtration, while uranium requires equipment selected and verified for the measured result. Other findings may support sediment, iron, manganese, hardness, sulfur-odor, or ultraviolet treatment. If the results call for radon aeration, we can direct the homeowner to an independent company.
Water Treatment Services We Provide
Our team installs and services water-treatment equipment for Brentwood 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
