We Know
Hudson Homes.
Hudson lies across the Merrimack River from Nashua, with its town center near the meeting of Routes 3A, 102, and 111. A.J. LeBlanc Heating serves its established suburban neighborhoods, older homes, and later development throughout this community of roughly 25,000 residents.
Housing: Most Hudson homes are single-family houses, with a smaller share in multi-family buildings. Construction was especially active during the 1970s and 1980s, with some homes dating to the 1960s, and the median home dates to about 1983. Ranches, split-levels, and capes are common in the established neighborhoods. Many of those homes now contain original or earlier replacement heating and cooling equipment that deserves a careful evaluation before the next repair or upgrade.
Furnaces, Boilers &
Heat Pumps
Heating in Hudson
Natural gas from Liberty Utilities is the largest heating-fuel source in Hudson, while oil still heats about one-quarter of the town and propane and electric systems are also part of the mix. A.J. LeBlanc Heating replaces gas, oil, and propane furnaces and boilers and can complete an oil-to-gas conversion where service is available. Cold-climate heat pumps provide another option for homes with the right layout and electrical capacity. We evaluate the existing system and the home's heating needs before helping the homeowner compare repair and replacement choices.

Air Conditioning &
Mini Split Installation
Cooling in Hudson
Many Hudson ranches, capes, and split-levels were built without ductwork for central air conditioning. Mini splits can provide cooling in separate zones and supplemental heat without requiring a new duct system. Homes with a forced-air furnace and suitable ducts may be good candidates for central A/C or a ducted heat pump. A.J. LeBlanc Heating checks the home's layout, airflow, duct capacity, and electrical service so the equipment is sized for the actual space.
Cooling Services We Provide
Hudson homeowners can call us for central air conditioning, heat pumps, and ductless mini splits. Our team has installed thousands of ductless systems throughout Southern NH. We respond quickly for summer breakdowns and full system replacements.

Water Treatment in Hudson
Hudson's public water comes mainly from the Weinstein groundwater well in Litchfield, with Pennichuck water available as a supplemental supply. The town chlorinates the water, adjusts pH, and treats for iron and manganese. That information applies to the public system, not private wells.
Public-water customers may choose whole-house activated carbon to improve taste or odor, or an under-sink carbon or reverse osmosis system for filtered drinking water. For a private well, A.J. LeBlanc Heating starts by collecting samples for an independent laboratory and uses the results to select 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.
Water Treatment Services We Provide
We provide water-treatment installation and service in Hudson. Independent laboratory results guide every private-well recommendation, from drinking-water filtration to complete whole-house treatment.
- Well Water Filtration
- Water Softeners
- Iron & Manganese Removal
- Reverse Osmosis Drinking Water
- UV Purification

Plumbing in Hudson
Hudson's 1970s and 1980s ranches, capes, and split-levels are now at an age when valves, fixtures, supply lines, drains, and water heaters may need attention. A.J. LeBlanc Heating repairs running toilets, leaking faucets and pipes, failed shutoffs, slow drains, and unreliable water heaters. In homes served by private wells, our plumbers service well tanks and pressure switches.
We trace the problem to the part that failed and explain whether a focused repair or replacement offers the better value.
