Reviews From Southern NH Homeowners
A.J. LeBlanc Heating responded very quickly to our plumbing leak. First time I have called LeBlanc Heating for plumbing, and the plumber they sent was very pleasant, clean, and quick. He made sure we had no other problems while he was here. Very professional and very reasonable! I will definitely use them again.
John WalkerPlumbing customerThe installer was very professional. He performed the installation quickly and cleaned up when he was done. I am extremely satisfied with the job that was done.
Philip GilbrethPlumbing Service customerI will put A.J. LeBlanc Heating on my 1st line plumber to call in the future. Very professional, and work was awesome even removing a component that kept wearing out with apex that won't give me that problem again. Then the final touch was when I received the bill. The pricing was so affordable I was kind of shocked. Thank you!

Frequently Asked Questions
How quickly can you repair my water heater?
For emergency calls involving water damage or complete loss of hot water, we prioritize response. For non-emergency repairs, we typically schedule within one to two business days.
What water heater brands do you service?
We service all major brands including Navien, Bradford White, Rheem, A.O. Smith, State, Rinnai, and all others.
Should I repair or replace my water heater?
A storage water heater often provides around 15 years of service, while a properly maintained tankless unit may last around 20 years. Age alone does not decide the recommendation. We look at where the failure is, tank condition, repair cost, warranty coverage, water quality, and service history. A sound tank with a replaceable control, valve, element, or ignition part may be worth repairing. A tank leaking through its body cannot be repaired and needs replacement.
Do you service tankless water heaters?
Yes. We service all types of tankless water heaters including Navien, Rinnai, and other major brands.
