Cleaning of furnace/ducts. Did not go to furnace area after cleaning. Discovered two days after servicing ( we were not home for these days) that our furnace was not working, went to furnace room to investigate. Found the furnace front cover leaning against unit, with two screws lying on the floor. Numerous attempts to contact company, finally reached the OWNER, who came to my home within the hour. Interior temperature of home 16 degrees. Rude and condescending immediately upon entering my home and upon entering the furnace area started yelling at me " who took this apart- we can't be liable for this!! He then pushed a button and the furnace started working again- he looks at me like I was an idiot for not doing that and I felt like he was annoyed for coming out and turning my furnace back on. I asked him to put the furnace cover back on and he refused stating he did not have time for this and that he was helping me!! He lectured me that his people always make sure the unit is in working order before they leave. They also put the dirty furnace filter back in- companies I have used in the past at least put a cheap one in ( at least it is clean). When my husband came home, I told him the story and he tried to contact the owner to discuss how he treated me and handled the entire situation. None of our calls were answered. This is how the OWNER handles after care service ( after I just spent $520)!! HORRIBLE, RUDE CUSTOMER SERVICE!!!
