How We Price Water Heater Repair
Hourly Billing, One-Hour Minimum
Service calls are billed by the hour with a one-hour minimum. You pay for the actual time and parts to fix your water heater, not an inflated flat-rate book price.
No Trip Charges
We do not charge just to show up. Standard business-hours rates apply during the workweek. After-hours and emergency calls have a premium rate that we disclose up front before any work begins.
Honest Repair-or-Replace Assessment
If your tank is past its useful life or the repair cost is approaching replacement cost, we will tell you. Free written estimate on replacement so you can compare honestly.
No Commission, No Upsell
Our technicians are paid to fix your water heater, not to sell you a new one. They are not on commission. If a repair makes sense, we repair.
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 kindof shocked. Thank you!
