A.J. LeBlanc Heating Wins Best of The 603 for the Fifth Year in a Row
In 2025, A.J. LeBlanc Heating, Plumbing, and Electric was once again voted Best of The 603 by Manchester Radio Group listeners. This marks the fifth consecutive year we have been recognized as one of New Hampshire's top home service companies for heating, cooling, plumbing, and electrical work. Five straight years of community recognition speaks to sustained customer trust across thousands of southern New Hampshire homes served.
About the Best of The 603 awards
Manchester Radio Group's annual "Best of The 603" awards are determined by listener voting across New Hampshire home services, professional services, dining, and retail categories. Unlike industry panels, Best of The 603 reflects direct customer experience: who do NH residents actually trust to fix their plumbing, install their AC, wire their EV charger, or service their generator?
Earning recognition for one year signals a strong year. Earning it five years in a row signals sustained service quality across many seasons, many homes, and many service calls.
