Garbage Disposal FAQ
How much does garbage disposal installation cost?
A garbage disposal installation in Southern NH typically runs $200 to $400 installed, depending on whether an electrical outlet is needed and the cost of the disposal itself. A.J. LeBlanc Heating provides upfront quotes.
What size disposal do I need?
For most Southern NH households, a 1/2 HP disposal handles everyday use. For heavier use or harder-to-grind food waste, a 3/4 or 1 HP unit is worth the upgrade. A.J. LeBlanc Heating recommends based on your usage.
My disposal just hums but doesn't spin, is it broken?
Not necessarily. It is probably jammed. There is a hex key port on the bottom of most disposals. Inserting a 1/4-inch hex key and turning it back and forth usually frees the jam. If that does not work, call A.J. LeBlanc Heating.
Do you need an electrician for disposal installation?
Only if there is no outlet under the sink. If there is one, the plumbing connection is all that is needed. If not, A.J. LeBlanc Heating handles both the plumbing and the electrical.
