5 stars for our technician and Fred’s Heating and Air. Had them come to give a second opinion about our not so old furnace that another company found several things “needing replacing” or perhaps a “new furnace”! A more thorough inspection was done by the Fred’s tech, as well as some terrific education about the items in question which as it turned out were NOT needing replacement and were all in good working order. I trust Fred’s honesty and integrity.
