Do you offer same-day water heater installation?
Yes. A.J. LeBlanc Heating master plumbers are typically available for same-day water heater service and replacement throughout Southern NH. We stock Bradford White, Navien, Rinnai, A.O. Smith, and State units. Call 603-623-0412 and we will assess availability immediately.
What's the difference between tankless and traditional water heaters?
A traditional water heater stores 40 to 80 gallons of hot water in a tank, keeping it warm continuously. A tankless (on-demand) unit heats water instantly as you need it, so you never run out and aren't paying to maintain a tank temperature. Tankless units are wall-mounted, smaller, and typically last longer. We help you evaluate which makes sense for your Southern NH home and usage.
Do you handle full kitchen and bathroom remodels?
Yes. A.J. LeBlanc Heating handles all the plumbing rough-in and finish work for kitchen and bathroom renovations across Southern NH. We coordinate with your GC or builder, pull all required permits, and install sinks, faucets, toilets, showers, tubs, and all related plumbing.
Are your plumbers licensed in New Hampshire?
Yes. All of our plumbers hold NH master plumber licenses and are fully insured. We are also not commission-based, so our plumbers earn the same regardless of what they recommend, and you always get an honest assessment of what your Southern NH plumbing actually needs.

Yes. Emergency plumbing service is available 24/7 for all existing A.J. LeBlanc Heating customers throughout Southern NH. If you have a burst pipe, major leak, or no hot water, call 603-623-0412 any time.
