Verified record
A.J. LeBlanc Heating works out of 45 South River Road in Bedford and covers heating, cooling and plumbing across southern New Hampshire. The company holds New Hampshire mechanical business entity licence MBE0006399, verified active against the state registry, and an individual gas fitter licence, GF0700136, held by Robert M Bouchard, is registered against the business. The Better Business Bureau lists it as accredited with an A+ grade, and its Google profile carries 4.8 stars from 748 ratings across 344 reviews since 2021 — 56 of them in the last six months. Speed under pressure is the thread running through the record. A customer who came home in August 2026 to a dead air conditioner had a technician there within the hour and the system running again, at what he called a reasonable after-hours cost. A May 2026 household with a leaking hot water heater — not customers at the time — had someone there in 45 minutes to shut the water off and quote, and a new heater fitted the next day. A two-zone HVAC replacement ran through the four coldest days of a hard January 2026 winter with crews swarming the job to keep it moving. Customers name their technicians and ask for them again. David H turns up across annual maintenance on furnaces, tankless water heaters and three-unit mini-split sets; Peter D serviced a set of six mini-splits, inspecting, cleaning and testing each one while explaining how to run them season by season. Others describe a boiler, water tank and water filtration system installed inside two days. Several accounts are specifically about not being oversold. A 2021 customer with badly corroded circulators was offered a repair rather than a new boiler, and the final bill came in under estimate. A 2024 customer with an old chimney asked a LeBlanc boiler technician to referee three wildly different chimney quotes and got advice on what was actually needed. On Reddit in May 2026, one homeowner said other vendors wanted to convert his house to propane and cut far more vents while LeBlanc replaced the furnace and added a three-ton Bosch heat pump; another posted quotes for an indirect hot water heater install at $6,800 and $7,200 against LeBlanc's $4,800. The friction is around emergency access and scheduling. A December 2025 caller with a Saturday emergency was told to call back Monday because he was not a regular customer, and a January 2023 caller says nobody came out at night at all. A 2024 reviewer said the furnace work he was paying for had stopped being done completely and switched companies. A 2022 customer at a townhouse complex had scheduling and permitting coordination missed twice. And a 2024 boiler replacement — praised overall, with a temporary boiler fitted so the household had hot water — ran into complications and a heating oil spill just as the crew left, both eventually put right. A deep bench with genuine emergency capacity and a habit of quoting the smaller fix. If you are not already a customer, ask directly how out-of-hours calls are prioritised before you need one.
“My Dad recently used AJ LeBlanc and was very impressed. Would recommend them to anyone who is on the lookout for heating.”
“Paul the plumber quoted an indirect hot water heater install Higher then Heritage when I recently got quotes Heritage was 6800 Paul the plumber was 7200 AJ was 4800 I didn’t think it was possible.”
“AJ Leblanc. They replaced a furnace and added a 3ton Bosch heat pump. Other vendors wanted to replace oil with propane, cut way more vents, convert to fully electrical, the list goes on.”
“AJ Leblanc is excellent.”
“I like Aj Leblanc I just need to get in the habit of calling them first….”
