In 2024, the readers of the New Hampshire Union Leader voted A.J. LeBlanc Heating the winner in four categories at the Readers' Choice Awards: Best Plumber, Best Heating and Air Conditioning Contractor, Best Electrician, and Best Generator Installer. The four-category sweep was a recognition of our work across the full residential mechanical scope and the trust the southern New Hampshire community has placed in our team across nearly a century of service.

A look at what each award meant and how we have built the business across each trade.

A tradition of community-voted recognition

For more than 95 years, A.J. LeBlanc Heating has been a cornerstone of the Greater Manchester and southern New Hampshire communities, providing plumbing, heating, cooling, electrical, and generator services. The 2024 Union Leader Readers' Choice recognition was determined by reader votes, not industry panels, which means it reflects direct customer experience across the state.

Best Plumber

Our licensed plumbers handle the full range of residential plumbing across southern NH:

  • Water heater installation, service, and replacement (tank, tankless, and heat pump water heaters)
  • Faucet, toilet, garbage disposal, and fixture service
  • Leak detection and repair
  • Drain cleaning
  • Sump pump installation and service
  • Whole-home water leak detection systems (Moen Flo, Phyn)
  • Deduct meter installations
  • 24/7 emergency plumbing response

The Best Plumber category recognized consistent service quality across thousands of NH homes year after year.

Best Heating and Air Conditioning Contractor

Our HVAC team designs, installs, and services the systems that keep NH homes comfortable year-round through both long winters and humid summers. The work covers:

  • High-efficiency gas, propane, and oil furnaces
  • Boilers (cast-iron, condensing, combi)
  • Cold-climate heat pumps (central and ductless)
  • Dual-fuel system design and installation
  • Central air conditioning
  • Ductless mini split installation (single and multi-zone)
  • Smart thermostat installation and configuration
  • Indoor air quality solutions (UV, HEPA, electronic air cleaners, HRV/ERV)
  • Annual heating and cooling tune-ups
  • 24/7 emergency no-heat and no-cool response

We are a Mitsubishi Diamond Dealer and a Bosch Platinum Dealer, among other manufacturer certifications.

Best Electrician

Residential electrical work across NH is handled by our licensed in-house electricians:

  • Electrical panel upgrades and replacement
  • EV charger installation (Tesla, Rivian, all major brands)
  • Whole-house surge protection
  • Generator transfer switch installation
  • Service upgrades
  • Lighting, outlet, and switch installation
  • Code compliance and inspections

Being recognized as Best Electrician in addition to Best Plumber and Best HVAC reflects the genuine in-house electrical capability we have built, rather than subcontracting electrical work to outside firms.

Best Generator Installer

Whole-house standby generators are increasingly common in NH as ice storms, wind events, and grid demand all make extended outages more likely. Our generator team takes care of:

  • Generac and Kohler standby generator installation
  • Generator sizing consultations (right-sizing the unit to your home's actual load needs)
  • Power management module installation (lets smaller, more efficient generators serve larger homes)
  • Automatic transfer switch installation
  • Annual generator service and load testing
  • Portable generator transfer switch installation

Gratitude to our customers and team

Awards like the Union Leader Readers' Choice belong to the customers who voted and to the team that earns the votes one job at a time. To our customers across southern NH: thank you for the trust. To our licensed plumbers, electricians, HVAC installers, service technicians, dispatchers, and support staff: the work belongs to you.

Continuing recognition

The 2024 four-category win was part of a longer streak of recognition from both the Union Leader Readers' Choice and Manchester Radio Group's Best of The 603 awards. We do not take repeated recognition for granted. Every customer call is the next opportunity to earn the next vote.
