Buyer Beware! I called Shavitz for a written estimate to replace my AC & 60K BTU Furnace. Sales rep shows up in dress shoes to climb my ladder and is too lazy to view 2.5T AC on rooftop! He refuses to give me written estimate and gives me verbal price for inadequate equipment 2T AC & 45K furnacethat is 3x higher than highest estimate for 2.5T AC & 60K furnace obviously to maximize his commission! He says he's afraid his guys will fall thru my ceiling too! He refuses to give written quote after wasting 1.5 hours of my time! Good thing cuz I read several negative reviews about their installers falling thru ceilings. Buyer beware heads up!
