Good Morning!
You can reduce energy loss by making sure your pipes are properly insulated. Insulation decreases the chance your pipes will freeze and it cuts down on sweating which causes mold to grow.
Check to see if your pipes are warm to the touch. If they are, the pipes are a good candidate for insulation. You can find pre-slit pipe foam at most hardware and do-it-yourself stores. Cut it to size and fasten it around the pipes with duct tape.
Make sure your pipes are clean before you cover them, and don’t compress the insulation too much, because it will not work as well.
