How We Price Boiler Work
Free Estimates on New Installs
If your boiler needs to be replaced, the estimate is free. We come out, look at your system and venting, and give you a written quote.
Hourly Billing, One-Hour Minimum
Repair service is billed by the hour with a one-hour minimum. You pay for the actual time and parts to fix your boiler, 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.
No Commission, No Upsell
Our technicians are paid to fix your boiler, not to sell you a new one. They are not on commission. If a repair makes sense, we repair.
Reviews From Southern NH Homeowners
We have had A.J. LeBlanc Heating for plumbing work and more recently a heat pump installation. Everyone we have come in contact with was polite, easy to work with and talk to. We will continue to do business with them and would recommend them to friends or family.
Gwendolyn BowenHeat Pump customerAfter getting several estimates, it was obvious that A.J. LeBlanc Heating had the experience I was looking for. I was converting to gas from oil and I needed to understand how it worked and what was required to make the change. All permitting and inspections went without a hitch and as scheduled. Installation is clean and everything is working as promised.
Thomas LowHeating Service customerThey came in with the best price for a new furnace. Friendly, quick, and will only use them to service our furnace from now on.

Frequently Asked Questions
How quickly can you repair my boiler?
For emergency no-heat calls in winter, we prioritize response. For non-emergency repairs, we typically schedule within one to two business days. Call 603-623-0412 for current availability.
What boiler brands do you service?
We repair all major brands including Navien, Weil-McLain, Burnham, Viessmann, Buderus, Biasi, Rinnai, System 2000, Utica, and more.
Should I repair or replace my boiler?
If your boiler is under 15 years old and the repair cost is less than 50 percent of replacement cost, repair is usually the right call. We will give you an honest assessment.
Do you offer annual boiler maintenance?
Yes. Annual maintenance provides a regular tune-up that catches problems early and keeps your boiler running efficiently. Ask about our Rate Lock program for discounted off-peak tune-up pricing.
