“

Earlier this year, we worked with St Amant H S & Sons Inc to install a new furnace, and everything went perfectly. The team was professional, efficient, and cleaned up after themselves. Our new furnace looks great!<br><br>More recently, we hired them again to replace our water pump and repair the foot valve in our well. They went above and beyond to help us resolve these issues. We’re very happy with their service and would definitely recommend them — very nice people to deal with!
